What happened to the sedimentary and igneous
rocks?
Answer:
Sedimentary rocks are formed on or near the Earth’s surface, in contrast to metamorphic and igneous rocks, which are formed deep within the Earth. The most important geological processes that lead to the creation of sedimentary rocks are erosion, weathering, dissolution, precipitation, and lithification.
Erosion and weathering include the effects of wind and rain, which slowly break down large rocks into smaller ones. Erosion and weathering transform boulders and even mountains into sediments, such as sand or mud. Dissolution is a form of weathering—chemical weathering. With this process, water that is slightly acidic slowly wears away stone. These three processes create the raw materials for new, sedimentary rocks.

how do seasonal changes in the amount of sea ice influence the salinity of the remaining surface water? is water density greater before or after sea ice forms? explain.
As the season warms, the ice melts and the water becomes less salty. This affects the density of water. Density is reduced. As ice forms, the density of water increases.
What is the density of water?Seawater density or density is the mass of seawater per unit volume. At the same temperature, liquid water has a density of nearly 1,000 kg per cubic meter. In general, seawater density increases with decreasing temperature, increasing salinity, and increasing seawater depth.
The density of seawater at sea level is 1,020 to 1,029 kg per cubic meter. The ocean floor has the highest density because the surface is contaminated with seawater. At the deepest part of the ocean, the density of seawater can reach 1,050 kg per cubic meter.

How does the fraction of oxygen in earth’s atmosphere today compare to what it was 3 billion years ago?
The fraction of oxygen in Earth's atmosphere today is approximately 21%, while it was less than 0.1% around 3 billion years ago.
The fraction of oxygen in Earth's atmosphere today is significantly higher compared to what it was 3 billion years ago. Oxygen levels on Earth have undergone significant changes over geological time due to biological and geological processes.
Around 3 billion years ago, Earth's atmosphere was primarily composed of nitrogen, carbon dioxide, water vapor, and trace amounts of other gases. Oxygen was present in only trace amounts, estimated to be less than 0.1% of the atmosphere.
The increase in oxygen levels occurred as a result of the photosynthetic activity of early cyanobacteria, which released oxygen as a byproduct during photosynthesis. Over millions of years, oxygen levels gradually increased due to the proliferation of these oxygen-producing organisms.
Today, oxygen makes up approximately 21% of Earth's atmosphere. This increase in oxygen has had profound effects on the evolution of life on Earth, allowing for the development of more complex organisms that rely on oxygen for respiration.
In summary, the fraction of oxygen in Earth's atmosphere has significantly increased from less than 0.1% around 3 billion years ago to approximately 21% in the present day, primarily due to the activities of oxygen-producing organisms.

Which statement best explains Australia’s population density?
a) Much of the interior is dry and unsuitable for farming.
b) Mountain ranges limit coastal populations.
c) The number of Aboriginal people has steadily declined.
Answer:
B
Explanation:
A doesn't concern population density, c concerns population diversity. B explains how due to the mountain ranges on the east coast of Australia, it is harder to inhabit that area resulting in the majority population living elsewhere.
Mountain ranges limit coastal population in Australia.
Thu, the correct option is B.
What is population density?Population density is the number of people in a given area of land.
The population density, or the number of people divided by the area's size, is determined by the number of people who reside there. Many different creatures' distribution, growth, and migration can all be described using population density.
Three alternative methods are frequently used to determine population density. There are three types of density: agricultural, physiological, and mathematical.
A high population density indicates that the population is large for the country's size. Countries with dense populations include Belgium and the Netherlands. Large nations with low densities include Australia and Canada.
A region's population density rises as a result of the presence of employment opportunities and other economic activity. Typically, heavily populated areas have good infrastructure for transportation, energy, water, and sanitation.

what were the two (2) observations that scientists made that indicated magma was rising in mt. pinatubo?
The two observations that indicated magma was rising in Mt. Pinatubo were an increase in seismic activity and ground deformation.
Mount Pinatubo is an active volcano located in the Philippines. In 1991, the volcano experienced a major eruption that caused widespread destruction and loss of life.
Prior to the eruption, there were two key observations that indicated that magma was rising within the volcano: an increase in seismic activity and ground deformation.
Seismic activity refers to the vibrations or waves that are generated by movements within the earth's crust. When magma begins to rise within a volcano, it can cause an increase in seismic activity as the movement of the magma generates vibrations that can be detected by seismographs.
In the case of Mount Pinatubo, there was a significant increase in seismic activity in the months leading up to the eruption. This increase in seismic activity was one of the key indicators that magma was rising within the volcano.
Ground deformation is another key observation that can indicate the movement of magma within a volcano. As magma rises towards the surface, it can cause the ground above it to deform or bulge upwards.
This deformation can be detected using a variety of methods, including satellite imagery, GPS, and ground-based measurements. In the case of Mount Pinatubo, ground deformation was also observed in the months leading up to the eruption.
The deformation was initially small, but it gradually increased over time, indicating that magma was continuing to rise towards the surface.
Taken together, these two observations - an increase in seismic activity and ground deformation - provided strong evidence that magma was rising within Mount Pinatubo prior to the eruption.
This information was critical for scientists and authorities who were monitoring the volcano, as it allowed them to issue timely warnings and evacuate residents from the surrounding areas before the eruption occurred.

Describe TWO ways that topography affects the spatial pattern of population distribution shown on the map.
Answer:
Rugged and undulating are the two ways which shows that topography effects the population of an area.
Explanation:
Topography has a great effects on the distribution of population. Rugged topography is a type of topography in which the surface is uneven and rocky while undulating topography refers to land which is just like waves having lower and higher points. So both of these topography decreases the population of people because on these lands walking is difficult due to no roads and uneven surface so that's why people settle on the plain areas.

Answer:
45, 54, 72
Explanation:
In this case, a quadrilateral is like a square, with 4 sides but it's sides are longer than a square.
The perimeter of any geometrical figure is the sum of all the side's lenght, so, if we have the perimeter and the value of one side, we can deduce the lenght of the other sides because we have a data of the ratio. Let's first see how much is left on the missing sides.
P = a + b + c + d
207 = 36 + b + c + d
171 = a + b + c
This means that the sum of the other 3 sides is 171. We know that the ratio of those sides is 5:6:8, so the sum of these sides can be written like this, in function of those ratios:
171 = 5x + 6x + 8x
171 = 19x
x = 9
With this number we can now calculate the sides of the quadrilateral:
a = 5x = 5 * 9 = 45
b = 6x = 6 * 9 = 54
c = 8x = 8 * 9 = 72
Therefore the missing sides's lenght are:

As the nebula begins to shrink and spin, what else does it begin to do?
As the nebula begins to shrink and spin, it also starts to flatten into a spinning disk. The process of star formation begins with the gravitational collapse of a nebula, which is a cloud of gas and dust in space.
As gravity pulls the particles inward, the nebula starts to shrink and spin due to the conservation of angular momentum. As a result, the nebula begins to flatten into a spinning disk-like structure.
This flattening and spinning of the nebula into a disk shape is a common phenomenon observed in the early stages of star formation. The conservation of angular momentum causes the collapsing nebula to flatten along its axis of rotation, similar to how a spinning ice skater extends their arms to increase their rotational speed. This spinning disk is known as an accretion disk.
The formation of an accretion disk is essential for the subsequent stages of star formation. Within the disk, the material continues to collapse and condense, eventually leading to the formation of a protostar at the center.
The protostar accumulates mass from the surrounding disk, while the remaining material in the disk may eventually coalesce into planets or other celestial objects.
Therefore, the flattening and spinning of the nebula into an accretion disk are crucial steps in the process of star and planet formation.

determine the number of unpaired electrons in the octahedral coordination complex [mn(no2)6]3−. number of unpaired electrons:
the octahedral coordination complex [Mn(NO2)6]3- has one unpaired electron in the eg orbital.
In the octahedral coordination complex [Mn(NO2)6]3-, the Mn ion has a +3 charge. The electronic configuration of Mn in its +3 oxidation state is 3d4, where 3d represents the valence shell electronic configuration and 4 represents the number of electrons in the d-orbital.
In an octahedral complex, the d-orbitals split into two sets of three: t2g and eg. The t2g set contains three orbitals that are lower in energy, while the eg set contains two orbitals that are higher in energy. The sixth d-orbital is non-bonding and has the same energy as the t2g set.
In [Mn(NO2)6]3-, the six NO2 ligands donate six electrons to the Mn ion, which are used to fill the t2g and eg sets. The t2g set is completely filled with electrons, while one of the eg orbitals has a single electron. Therefore, there is only one unpaired electron in the complex.
In summary, the octahedral coordination complex [Mn(NO2)6]3- has one unpaired electron in the eg orbital.

the presence of ___________ on the surface of mars provides additional evidence for a wet martian past.
The presence of hydrated minerals on the surface of Mars provides additional evidence for a wet Martian past. These minerals, such as clay minerals and sulfates, require water to form. Their presence suggests that liquid water once existed on Mars, indicating a more habitable environment in the past.
The presence of hydrated minerals on Mars provides important clues about the planet's history and the conditions that may have prevailed in the past. Hydrated minerals, like clay minerals and sulfates, contain water molecules within their crystal structures. These minerals require the presence of liquid water over an extended period to form. Therefore, their identification on the Martian surface suggests that water was once present in significant amounts.
The existence of hydrated minerals strengthens the case for a wet Martian past and supports the hypothesis that Mars had a more habitable environment in the past. The discovery of these minerals through remote sensing techniques, such as spectroscopy, allows scientists to infer the past presence of liquid water, even if it is not present in liquid form today.
This evidence adds to other indicators of a wet Martian history, including the presence of ancient riverbeds, sedimentary layers, and features resembling shoreline formations. Overall, the presence of hydrated minerals on Mars provides valuable additional evidence for the planet's past as a potentially habitable world with liquid water.

How does air move in the atmosphere?
a. From high pressure to low pressure
b. From warm regions to cold regions cFrom the equator to the poles dFrom the lower atmosphere to the upper atmosphere
Air moves in the atmosphere from high pressure to low pressure. Air pressure is the force exerted by air molecules on the surface below. The movement of air in the atmosphere is due to the pressure differences caused by temperature differences in the atmosphere and the rotation of the earth.
Air moves in response to differences in pressure, which are caused by differences in temperature. When air warms up, it expands, becomes less dense and rises, causing an area of low pressure. On the other hand, when air cools, it contracts, becomes more dense and sinks, creating an area of high pressure.
The movement of air from high to low pressure is what causes wind to blow. The greater the difference in pressure, the faster the wind will blow. Winds move from areas of high pressure to areas of low pressure.
When air is heated at the equator, it expands and rises, causing an area of low pressure. This warm air rises and moves towards the poles, creating a circulation pattern in the atmosphere known as the Hadley cell.
As this air cools, it sinks back down towards the surface at around 30 degrees latitude, creating an area of high pressure known as the subtropical high.
From here, the air flows back towards the equator, completing the circulation cell. This movement of air is responsible for the trade winds that blow from east to west across the tropical regions of the world.
In conclusion, the movement of air in the atmosphere is caused by differences in pressure, which are caused by differences in temperature. Air moves from areas of high pressure to areas of low pressure, and the circulation of air around the world is driven by temperature differences between the equator and the poles.
