The rapid cooling of lava on the earth's surface produces a rock characterized by a fine-grained texture. This type of rock is known as extrusive igneous rocks, and it is formed when lava cools down on the earth's surface quickly.
The fast cooling does not give time for crystals to form, resulting in small crystals and a uniform texture. The size of the crystals is determined by the rate of cooling, with rapid cooling resulting in tiny crystals and slow cooling resulting in larger crystals.
Extrusive igneous rocks are formed by the solidification of lava that flows out of a volcano or a fissure on the earth's surface. This lava flows at high temperatures and cools quickly due to contact with the air. They have a number of uses, including construction and as a source of crushed stone for road construction. Some of the most common examples of extrusive igneous rocks include basalt, andesite, rhyolite, pumice, and obsidian. Basalt is the most common type of extrusive rock on the earth's surface, and it is often used in the construction industry because of its durability.

An island is 2.1mi due north of its closest point on a straight shoreline. A visitor is staying at a cabin on the shore that is 7.9mi from that point. The visitor is planning to go from the cabin to the island. Suppose that the visitor runs at a rate of 5mph and swims at a rate of 1mph. How far should the visitor run before swimming to minimize the time it takes to reach the island? Assume that the distance from the point on the shore closest to the island and the point at which the visitor: begins swimming is x. Then the time spent running by the visitor as a function of x is T r
=hr Assume that the distance from the the island and the point at which the visitor begins swimming is y. Then the time spent swimming by the visitor as a function of y is T s
=hr What is the total time spent running and/or swimming by the visitor as a function of x ? T(x)= hr How far should the visitor run from the cabin in order to minimize the time it takes for them to reach the island? mi What is the minimum amount of time it will take for the visitor to reach the island from the cabin? hr NOTE: you may use decimals in your answers to this problem. If you enter an answer containing decimals, make sure it is correct to at least 3 decimal places.
The visitor should run a distance of 7.9 miles from the cabin to minimize the time it takes to reach the island.
To determine the distance the visitor should run before swimming to minimize the time it takes to reach the island, we need to find the minimum point of the total time function, T(x).
Given:
Distance from the point on the shore closest to the island to the cabin = 7.9 mi
Distance from the island to the point at which the visitor begins swimming = y
Running speed of the visitor = 5 mph
Swimming speed of the visitor = 1 mph
Let's derive the total time function:
T(x) = T_r + T_s
To find T_r, we divide the distance to be covered by running (x) by the running speed:
T_r = x / 5
To find T_s, we divide the distance to be covered by swimming (y) by the swimming speed:
T_s = y / 1 = y
Substituting these values into the total time function:
T(x) = (x / 5) + y
We know that the distance from the cabin to the island is the sum of the distances covered by running and swimming:
x + y = 2.1
Rearranging the equation, we get:
y = 2.1 - x
Substituting this value of y into the total time function:
T(x) = (x / 5) + (2.1 - x)
Simplifying the equation:
T(x) = (x / 5) + 2.1 - x
To minimize the time, we differentiate T(x) with respect to x and set it equal to zero:
d(T(x)) / dx = (1 / 5) - 1 = 0
1 / 5 - 1 = 0
-4 / 5 = 0
Since -4 / 5 is not equal to zero, there is no critical point. We can conclude that the minimum time is achieved when the visitor runs the entire distance from the cabin to the island.
Therefore, the visitor should run a distance of 7.9 miles from the cabin to minimize the time it takes to reach the island.
The minimum amount of time it will take for the visitor to reach the island from the cabin is T(7.9) = (7.9 / 5) + 2.1 - 7.9 = 1.58 + 2.1 - 7.9 = 0.78 hours (or approximately 46.8 minutes).

Why did Native Americans join the missions? What made the missions so destructive? What specific Spanish actions made the missions oppressive?
1. The various myths that Americans created about the mound builders were that the mound builders were not American Indians, but instead a lost tribe from another continent.
Some said that the mounds were built by European explorers from long before Columbus’s time. These myths were harmful for American Indians as they worked to erase the historical contributions of American Indians to North American culture.2. The Hopewell and Mississippian cultures defy traditional stereotypes of American Indians living north of Mexico in several ways. The Hopewell culture, for example, was a highly developed trading culture that constructed elaborate burial mounds.
The Mississippian culture was marked by large, walled cities with complex social and political structures. These cultures were significant as they showed that American Indians had complex societies with advanced technologies and that North America was not just a “wilderness” waiting to be tamed by Europeans.3. Native Americans joined the missions for various reasons, including the promise of food, clothing, and shelter.
However, the missions were ultimately destructive because they were designed to assimilate Native Americans into European culture and religion. The specific Spanish actions that made the missions oppressive include forced labor, beatings, and whippings, as well as the removal of Native American children from their families and communities to be raised in European-style boarding schools.

For a given latitude, if the stated time of sunrise is 610 am at 120°00' W, what is the time of sunrise at 117°30' W?
To determine the time of sunrise at 117°30' W given the stated time of sunrise at 120°00' W, we need to consider the longitudinal distance between the two locations.
Since each degree of longitude corresponds to approximately 4 minutes of time, we can calculate the time difference between the two longitudes.
120°00' W - 117°30' W = 2°30' = 2.5 degrees
Next, we need to convert the longitude difference into time difference.
2.5 degrees x 4 minutes/degree = 10 minutes
Therefore, there is a 10-minute time difference between 120°00' W and 117°30' W.
Now, let's apply this time difference to the stated time of sunrise at 120°00' W, which is 6:10 am.
If we subtract 10 minutes from 6:10 am, we get:
6:10 am - 10 minutes = 6:00 am
Therefore, the time of sunrise at 117°30' W would be approximately 6:00 am.
It's important to note that this calculation assumes a consistent sunrise time across the latitude and does not take into account other factors that can affect the actual sunrise time, such as seasonal variations, local topography, or daylight saving time adjustments.

The graph on the left shows the flow and temperature of ocean currents, and the graphs on the right indicate the prevailing wind directions. Ocean currents and wind directions can combine to influence terrestrial climatic conditions. The land masses that will be warmer are the continents located in the western hemisphere.
The continents in the western hemisphere are expected to be warmer due to the clockwise motion of the ocean currents in the northern hemisphere. This motion allows for the warm water to be transported from the equator to the poles, which then creates a warming effect on the land masses.
On the other hand, the land masses in the eastern hemisphere are expected to be cooler due to the counter-clockwise motion of the ocean currents in the southern hemisphere.The prevailing winds also play a role in the climatic conditions of land masses. The land masses that are closer to the equator and that experience the trade winds will have a warmer climate due to the constant warm air flow.

german scientist that developed theory of continental drift
The theory of continental drift, which holds that Earth's continents move, was put forth by German scientist Alfred Wegener.
The scientist Alfred Wegener is most closely connected with the concept of continental drift. Wegener wrote a paper outlining his notion that the continents were "drifting" across the Earth, occasionally crashing through oceans and into one another, in the early 20th century. He referred to it as continental drift.
Between 1912 and 1929, he published a substantial amount of convincing fossil and geological evidence in support of his theory, but most other scientists disregarded it. The concept of continental drift didn't enter the mainstream of science until the 1960s.

The height of a right circular cone is multiplied by 3, but its radius remains fixed. By what factor will the volume of the cone be multiplied? A. 3 B. 9 C. 1/3 D. 1/9
Answer:
A. 3
Explanation:
A cone is a three dimensional shape with a flat base and curved surface. A right circular cone is a cone where the axis of the cone is the line meeting the vertex to the midpoint of the circular base.
The volume of a right circular cone = πr²h/3; where r is the radius of the cone and h is the height of the cone.
Let us assume the cone has a height of h, and radius of r. Hence:
Volume (V₁) = πr²h/3
If the radius remains fixed and the height is multiplied by 3. Hence:
V₂ = πr²(3h)/3 = πr²h = 3V₁
The volume would be multiplied by 3

Large rock slabs called tectonic plates, which separate the Earth's crust, are continually moving and changing the planet's topography. The theory of plate tectonics contends that the lithosphere, the planet's outer shell, is divided into a number of plates that move across the rocky interior of the planet and on top of its soft core (mantle).
The earth's crust is made up of enormous, solid rock "plates" that are separated by a rock layer. All of the edges of one plate touch the edge of the plate next to it because of how snugly the plates fit together.
