Answer:
There are three main types of rocks: sedimentary, igneous, and metamorphic. Each of these rocks are formed by physical changes—such as melting, cooling, eroding, compacting, or deforming—that are part of the rock cycle. Sedimentary rocks are formed from pieces of other existing rock or organic material

Which model of the solar system has Earth at the center of the revolving planets and stars? An example model is shown
below. A geocentric
B heliocentric
C Newtonian
D mercurian
Answer:
The geocentric model of the solar system has Earth at the center.
Explanation:
Throughout history, there have been multiple different models that humans thought of or created through observation. The two most famous ones from the past are the geocentric and heliocentric, with the geocentric coming earlier and for a very long time being the model that was accepted by the majority.
The geocentric model is a model that puts Earth in the center of the universe. Earth is presented as the most important and largest object in the universe. All of the space bodies, the Sun, stars, Moon, planets, were thought to revolve around Earth. As it turned out, this model was full of mistakes. Everything about it was wrong, with the only correct thing being that the Moon is actually revolving around Earth.

Active volcanoes are most likely to form at or near-
A. Transform plate boundaries
B. A convergent continental continental plate boundary
C. The center of the continents
D. A conversion oceanic continental continental plate boundary( subduction boundaries)
Answer:
A convergent oceanic-continental plate boundary (subduction boundaries).
Explanation:
Volcanoes form two types of plate boundaries, but also in the interior of the continental plates where there are hot spots below. The two types of plate boundaries where volcanoes can be found are the convergent and divergent plate boundaries, with the first ones having the vast majority of the volcanoes above the surface, while the second ones have the vast majority below the water surface.
At convergent plate boundaries, especially where continental and oceanic plates collide, there are volcanoes all across the plate boundary. This is due to the formation of a subduction zone, where the crust gest much more fragile around it and magma manages to push through and come out on the surface very easily. In practice, this can easily be seen by the fact that the majority of the volcanoes are found in the so-called ''Ring of Fire'' where there are numerous convergent boundaries between continental and oceanic plates.

Megalodon left an awful lot of teeth behind, but don't worry. It is likely that it had plenty of extras. Like modern sharks, Megalodon had several rows of teeth. Scientists believe that Megalodon had six rows of 7-inch-wide, razor-sharp teeth, top and bottom, for a total of 276 teeth in its giant jaws! It's no wonder, then, that this ancient shark left so many of them behind. Without this trail of teeth, we would not know that these enormous creatures swam the ancient oceans as a top predator.Select the two sentences that support the idea that scientists combine knowledge from different fields to do their jobs.
A. A Good Guess
B. In order to make the comparison, scientists use a mixture of math and science.
C. Scientists know that there is a relationship between the size of a modern shark's teeth and its body length.
D. Using a mathematical formula, scientists can use Megalodon's teeth to make an educated guess about how long it was.
E. Giant-sized Tooth Fairy
F. Megalodon left an awful lot of teeth behind, but don't worry
G. It is likely that it had plenty of extras.
H. Like modern sharks, Megalodon had several rows of teeth.

A segment has midpoint at (2,-4) and an endpoint at (5,-9). What are the coordinates of the other endpoint?
Answer:
The coordinates of the other endpoint are (-1,1).
Explanation:
Mid point = (2,-4)
One endpoint = (5,-9)
We need to find the coordinates of the other mid points. Let it is (x₂,y₂). Using the mid point formula to find it.
[tex]\text{Mid-points}(x_m,y_m)=(\dfrac{x_1+x_2}{2}, \dfrac{y_1+y_2}{2})[/tex]
We have, [tex]x_m=2, y_m=-4, x_1=5, y_1=-9[/tex]
[tex]\text{Mid-points}(2,-4)=(\dfrac{5+x_2}{2}, \dfrac{(-9)+y_2}{2})\\\\\dfrac{5+x_2}{2}=2\ \text{and}\ \dfrac{y_2-9}{2}=-4\\\\5+x_2=4\ \text{and}\ y_2-9=-8\\\\x_2=-1\ \text{and}\ y_2=1[/tex]
So, the coordinates of the other endpoint are (-1,1).

A. working in service industries
B. farming and herding
C. working in factories
D. mining for gold and other resources
Please select the best answer from the choices provided
Answer:
B. farming and herding
Explanation:
More than half of Africa's people make their living from farming. Although its total harvest has climbed over the past few decades, this is mainly because there are more people farming more land. But in many places there is no spare land to farm.

Answer:
Constructive Forces
Explanation:
The tectonic plates are doing the construction of the mountains and land formations.
Explain how plate tectonics and/or process of weathering, erosion, and deposition have shaped peninsula
Answer:
The material moved by erosion is sediment. Deposition occurs when the agents, usually wind or water, of erosion lay down sediment. Deposition changes the shape of the land. Water's movements (both on land and underground) cause weathering and erosion, which change the land's surface features and create underground formations.

If a rock started with 1,000 atoms of a parent but now contains 250 atoms, how many half lives have passed?
a. 0.5 half lives.
b. 1 half life.
c. 2 half lives.
d. 0.25 half lives.
Answer:
Option C. 2 half lives.
Explanation:
The following data were obtained from the question:
Original amount (N₀) = 1000 atoms
Amount remaining (N) = 250 atoms
Number of half-lives (n) =?
Half-life is defined as the time taken for the substance to reduce to half its original side. Mathematically, it can be obtained as follow:
N = 1/2ⁿ × N₀
N is the amount remaining.
n is the number of half-lives.
N₀ is the original amount.
Using the above formula, we can obtain the number of half-lives as follow:
Original amount (N₀) = 1000 atoms
Amount remaining (N) = 250 atoms
Number of half-lives (n) =?
N = 1/2ⁿ × N₀
250 = 1/2ⁿ × 1000
Cross multiply
250 × 2ⁿ = 1000
Divide both side by 250
2ⁿ = 1000/250
2ⁿ = 4
Express 4 in index form
2ⁿ = 2²
n = 2
Therefore, it will take two (2) half lives for the amount to get to 250 atoms.
Why does air pressure decrease from the troposphere to the exosphere?
HOW DOES ALTITUDE AFFECT YOUR BREATHING?
Answer:
In higher altitudes, the air is usually colder, less dense, and has less oxygen molecules. This means that if you were there, you would need to take more breaths to get the same amount of oxygen as you would at lower altitudes. Higher elevation makes it even harder to breathe.

What are three differences between brittle and plastic strain (may include both characteristics of the strain as well as the conditions and locations where each type of strain occurs), and give an example of the type of structure (deformation feature) associated with each type of strain. Make sure you clearly identify which type of strain is associated with each different trait and feature.
Answer:
elastic deformation: the rock returns to its original shape when the stress is removed.
plastic deformation: the rock does not return to its original shape when the stress is removed.
fracture: the rock breaks.
Explanation:
Stress is the force applied to an object. In geology, stress is the force per unit area that is placed on a rock. Four types of stresses act on materials.
A deeply buried rock is pushed down by the weight of all the material above it. Since the rock cannot move, it cannot deform. This is called confining stress.
Compression squeezes rocks together, causing rocks to fold or fracture (break) (figure 1). Compression is the most common stress at convergent plate boundaries.
Rocks that are pulled apart are under tension. Rocks under tension lengthen or break apart. Tension is the major type of stress at divergent plate boundaries.
When forces are parallel but moving in opposite directions, the stress is called shear (figure 2). Shear stress is the most common stress at transform plate boundaries.
Stress In Earth’s Crust
Enormous slabs of lithosphere move unevenly over the planet’s spherical surface, resulting in earthquakes. This chapter deals with two types of geological activity that occur because of plate tectonics: mountain building and earthquakes. First, we will consider what can happen to rocks when they are exposed to stress.
