When an earthquake occurs, two different types of waves are generated. These waves are called P waves and S waves. Examine the diagram, which shows how the waves travel through Earth. Which statement provides the best evidence of Earth’s structure, based on the information in the diagram?
A. The bending of S-waves shows that Earth has both an outer and an inner core.
B. Earthquakes provide no information because they cannot be detected all over Earth.
C. S-waves do not travel through liquids, so the evidence shows that Earth has an outer core layer made of liquid.
D. P-waves do not travel through liquids, so the evidence shows that Earth has an outer core layer made of liquid.
Answer:
Since S-waves do not travel through liquids, the evidence shows that Earth has an outer core layer made of liquid.
Summarize the Natural Processes of weathering ,erosion, and deposition
Answer:
I won’t do it in paragraph form cuz it will look very choppy but here you go:
Weathering is when the weather itself changes something, like when a metal bike gets rusty after sitting outside for a long time, or when a plant grows out of concrete.
Erosion is when something gets eroded away at. Like when something has water or wind is flowing against it so much that it changes shape. This is how canyons are made.
Deposition is when a gas turns into a solid, removing energy and skipping the liquid step (frost forming on car window)
Which two factors that influence weather are caused by the uneven heating of
Earth's surface by sunlight?
A. The formation of ocean currents that carry cold or warm water
B. The curving of an ocean current's path as Earth rotates
C. The formation of convection currents in the atmosphere
D. The curving of an air current's path as Earth rotates

Which statement about the sun's energy is correct?
A. It is entirely re-radiated back into space.
B. A part of it is destroyed by greenhouse gases.
C. A part of it is absorbed by atmospheric gases.
D. It makes Earth too hot for plants and animals to survive.
Answer:
C. A part of it is absorbed by atmospheric gases.
Explanation:
brainiest plz
The statement about the sun's energy is correct is a part of it is absorbed by atmospheric gases. Hence option C is correct.
What is atmosphere?Atmosphere is defined as the layer of gases kept in place by Earth's gravity and forming its planetary atmosphere. There are several minor layers in addition to the five major ones that make up Earth's atmosphere. The primary layers are, from lowest to highest, the troposphere, stratosphere, mesosphere, thermosphere, and exosphere.
Ozone (O3), which is present in the upper atmosphere, absorbs a sizable part of the Sun's UV radiation (the stratosphere). The Earth system does not become hotter as a result of solar radiation that Earth's surface or atmosphere reflect back into space. Heat is produced as a result of absorbed radiation.
Thus, the statement about the sun's energy is correct is a part of it is absorbed by atmospheric gases. Hence option C is correct.
