What are causes of climate change?
please elaborate : ) thank you!
why does our planet appear blue?
Answers
Answer:
Mars is the red planet; the Moon is an ashy grey; Saturn shines yellow and the Sun is a brilliant, blinding white. But our planet, when seen from the depths of space, whether we rise up above our world only slightly, in low-Earth orbit, or whether we travel to the outer reaches of our Solar System, shines a glorious blue.
Explanation:
Water vapor. The most abundant greenhouse gas, but importantly, it acts as a feedback to the climate. Water vapor increases as the Earth's atmosphere warms, but so does the possibility of clouds and precipitation, making these some of the most important feedback mechanisms to the greenhouse effect.
Carbon dioxide (CO2). A minor but very important component of the atmosphere, carbon dioxide is released through natural processes such as respiration and volcano eruptions and through human activities such as deforestation, land use changes, and burning fossil fuels. Humans have increased atmospheric CO2 concentration by more than a third since the Industrial Revolution began. This is the most important long-lived "forcing" of climate change.
Methane. A hydrocarbon gas produced both through natural sources and human activities, including the decomposition of wastes in landfills, agriculture, and especially rice cultivation, as well as ruminant digestion and manure management associated with domestic livestock. On a molecule-for-molecule basis, methane is a far more active greenhouse gas than carbon dioxide, but also one which is much less abundant in the atmosphere.
Nitrous oxide. A powerful greenhouse gas produced by soil cultivation practices, especially the use of commercial and organic fertilizers, fossil fuel combustion, nitric acid production, and biomass burning.
Chlorofluorocarbons (CFCs). Synthetic compounds entirely of industrial origin used in a number of applications,
You might have heard that the ocean is blue because the sky is blue, and water reflects the skies. Well, the sky is blue; that’s for certain. And the sky is blue because our atmosphere is more efficient at scattering blue (shorter-wavelength) light than red (longer-wavelength) light. This is the reason why the earth looks blue in color.

Answer:
W
Explanation:
Gravitational force is calculated by (m₁ * m₂)/d² where d is the distance, m₁ is the mass of one object and m₂ is the mass of another. Let's set m₁ to the mass of the star. Since the gravitational force we are trying to calculate is between the star and each object, the number amount of the star's mass is not required. Additionally, all objects are the same distance from the star, so distance measurements do not matter. All we have to do is compare the masses. By using the equation, logically, greater masses should yield a larger gravitational force. Thus, since W has the greatest mass, it must have the strongest gravitational force of attraction with the star.
Answer:
C) W
Explanation:
(m1 * m2)/d2, where d is the distance, m1 is the mass of one item, and m2 is the mass of another, is the formula for gravitational force. Let's put m1 equal to the star's mass. The mass of the star is not necessary since the gravitational force we are attempting to compute is between each item and the star. Distance measurements are also irrelevant because all objects are at the same distance from the star. To compare the masses is all that is necessary. Using the equation, more masses should theoretically result in a stronger gravitational pull. W must thus have the biggest gravitational pull on the star since it has the most mass.

What is the law that states “energy cannot be created or destroyed it can only change to different forms”?
A.Law of Conservation of Energy
B.Law of Conservation of Matter
C.Law of Gravity
D.Law of Physics
Answers
Answer:
A. Law of Conservation of Energy
Explanation:
The first law of thermodynamics, also known as Law of Conservation of Energy, states that energy can neither be created nor destroyed; energy can only be transferred or changed from one form to another. ... In other words, energy cannot be created or destroyed.
Law of Conservation of Energy is the law that states energy cannot be created or destroyed it can only change to different forms.
What do you mean by conservation of energy?The law of conservation of energy states that the amount of energy is neither created nor destroyed. For example, when you roll a toy car down a ramp and it hits a wall, the energy is transferred from kinetic energy to potential energy.
The law of conservation of energy states that energy can neither be created nor destroyed - only converted from one form of energy to another. This means that a system always has the same amount of energy, unless it's added from the outside.
The principle of energy conservation states that energy is neither created nor destroyed. It may transform from one type to another.

Use the words continuous, data, discrete, qualitative, and quantitative to summarize the types of data scientists work with.
Answers
Scientists are continuously studying data everywhere were if they were to be examining 2 million light-years away or something so discrete, you need a magnifying glass. Scientists are always, measuring things qualitatively and that means by their quality and not the quantity and that is how most scientific questions are answered. Now if scientists studied by there quantity, which means to use for how much there is instead of how good something is built or studied or measured scientists data would be much different.

2. What is carbon footprint?
3. What is the difference between finite and infinite?
4. How does using a fan lowers the greenhouse gas emissions?
5. What is mitigating?
6. How can sweeping minimizes noise pollution?
7. How does planting can conserve our natural resources?
Answers
Answer:
Explanation:
1) Hanging clothes to dry reduces electricity use and greenhouse gas emissions and makes clothes last longer.
2) The carbon footprint serves as an indicator to compare the amount of greenhouse gases emitted over the entire life cycle from the production of a good or service along the supply chain to its final consumption
3) The word 'Finite' itself describes that it is countable, and the word 'Infinite' means it is not finite or uncountable.
Answer:
Explanation:
1.) Using hanging clothes instead of using any machine(dryer) reduces the emission of gases and uses natural ways (sunlight, wind) to dry them up.
2.) Carbon footprint can be defined as the amount of greenhouse gases especially carbon dioxide (CO2) and methane emissions, that relate to daily human activities.
3.) If the no. of elements are countable then they are said to be finite, while if the no. of elements are uncountable then they are said to be infinite.
4.) Fans help to evaporate moisture from the skin, providing a cooling effect as it creates breezes instead of cooling it, while
Air conditioners remove heat from the air by using energy-intensive refrigeration cycles,
Thus fan helps to reduce greenhouse gas emissions.
5.) Mitigating refers to the act of reducing or minimizing the negative impacts of a particular issue or problem.

Mechanical energy can take on many forms, but these different forms can be categorized as either potential energy or energy of motion. The height an object is dropped from has an effect on the amount of energy in the object. Let’s conduct an experiment to see the effect.
:How does the height of an object affect the amount of mechanical energy it contains?
1:Variables What is the test variable?
Answers
The height of an object is crucial to the amount of energy something has because the higher up it is the most potential energy it has and kinetic energy it could have.
For example, if the height of a basketball was just a couple inches off the ground, it would not have a large amount of potential energy because because there is not much of a fall between the ball and the ground. However, if the ball was higher, there would be more potential energy because there is more room to fall.
---
"What is the test variable?"
The test variable, or independent variable in this case would be the height, as the scientist is changing the height in order to get different results in the total mechanical energy, which would be the dependent variable.

Title: Classifying Objects Purpose: The phone book, library, and the grocery store all use a classification system to make finding things much easier. In any classification system, objects are grouped together because they share similar characteristics. In this activity, you will gather, organize, and group objects based on their similarities. Procedure: Find a place (bedroom closet, kitchen, or garage) in your home that contains many objects. The name of this place will represent their kingdom. Write the name of the kingdom in the chart below. Divide the items into two groups. Each group should have similarities that are specific only to that group. Each group will represent a phylum. Write the name of one of the phylum along with the name of the items that belong to that phylum in the chart below. You can substitute pictures instead of the names of each item. Continue this process until you reach the last level of the classification system. Conclusion: 1. What traits did you use to separate the items into two different phyla? 2. What traits did you use to separate the items into two different classes? 3. What traits did you use to separate the items into two different orders? 4.

Answers
Answer:
H - 16
C - 4
O - 4
Explanation:
The reaction is
2CO + 4H2 = x CH4O
This means x=2 because the number of atoms have to be balanced. There are 8 Hydrogens on one side, meaning 16 in all. There are 2 Carbons on one side, meaning 4 in all. Lastly, there are also 2 Oxygens on one side, meaning there are 4 in all.
Atoms in the reaction are H- 8 atoms, C-2 atoms, and O- 2 atoms.
During the reaction, 2 molecules of methanol are produced.
We can write the equation as
CO+ 2 H2 ⇒ CH3OH
(Methanol)
For 1 molecule of CO and 2 molecules of H2 we get 1 molecule of CH3OH.
Hence, for 2 molecules of CO and 4 molecules of H2 we get 2 molecules of CH3OH(methanol).
From the reaction, we can easily calculate that 8 H atoms, 2 C atoms and 2 O atoms are getting reacted.
