Explanation:
James looked at a picture of rock layers while studying how scientists determine the ages of rocks. He looked at the variety of layers and understood that the law of superposition indicated something about the rock layer ages. What does the law of superposition indicate?
A. The rock layers can change their position and push younger rock layers under older rock layers.
B. The rock layers can change their position and push older rock layers under younger rock layers.
C. The rock layers on top are the youngest layers and the lower rock layers are the oldest layers.
D. The rock layers on top are the oldest layers and the lower rock layers are the youngest layers.
Answer:The answer would be C.
Explanation:
Law of superposition, a major principle of stratigraphy stating that within a sequence of layers of sedimentary rock, the oldest layer is at the base and that the layers are progressively younger with ascending order in the sequence.

Answer:
In the Explanation
Explanation:
Asteroid and Comets:
While asteroids consist of metals and rocky material, comets are made up of ice, dust, rocky materials and organic compounds. When comets get closer to the Sun, they lose material with each orbit because some of their ice melts and vaporizes. Asteroids typically remain solid, even when near the Sun.
Planets and dwarf planets:
The main difference between a dwarf planet and a planet is size. Because they are smaller, dwarf planets lack the gravitational forces needed to pull in and accumulate all of the material found in their orbits.
Inner Planets and Outer Planets
Inner planets are the closest 4 planet to the Sun in the solar system. They are mostly made of rocks(Mercury, Venus, Earth, and Mars.) Outer Planets are the 4 planets that are the most far away from the Sun. They are mostly made up of ice, and gas (Jupiter, Saturn ,Uranus and Neptune.)
Earth and Venus
While Venus and Earth have similar sizes and are solar system neighbors, they have evolved very differently. Venus today lacks oceans, appears to lack plate tectonics, and has a massive carbon dioxide atmosphere that creates a greenhouse effect that makes the surface a hot hell.

What is a comparison of the actual use of renewable, sustainable resources, including water and land, that a population uses for support relative to what is annually renewed. Non-renewable resources are not considered since they are not considered sustainable.
Answer:
Right here
Explanation:
The renewable resource can be used over and over and replaced very fast to human standers. Nonrenewable resources cannot be made fast enough by human standards.
The renewable resource can be used repeatedly and quickly replaced by human beings. By human standards, nonrenewable resources cannot be produced quickly enough.
What are Renewable and Non-renewable resources?A resource can be classified as renewable or nonrenewable based on whether it can replace itself at the rate it is used up or whether it has a finite supply. Timber, wind, and solar power are examples of renewable resources, whereas coal and natural gas are examples of non-renewable resources.
Renewable energy sources are a source of energy that is never exhausted and can provide a steady flow of clean energy. A natural resource that cannot be easily replaced by natural means quickly enough to keep up with use is referred to as a non-renewable resource which is also known as a finite resource. Fossil fuels made of carbon are one instance.
Thus, the renewable resource can be used repeatedly and quickly replaced by human beings. By human standards, nonrenewable resources cannot be produced quickly enough.

PLEASEE ANSWER BEFORE FRIDAY APRIL 30 Seven students looked at a barometer, a weather device that measures air pressure. They had different ideas about air pressure. This is what they
thought:
Kimberly:
Glenn:
Rae:
Jeff:
Oliver:
I think air has to be moving to create air pressure.
Air pressure is a downward force.
The higher in the atmosphere, the greater the air pressure.
Air pressure is the same in all directions.
Air pressure increases as the number of air particles increases.
Warm air masses have higher pressure than cool air masses.
When air pressure decreases, it might rain or snow.
Cameron:
Jay:
Circle the names of the students you agree with and describe why you
agree. Describe your ideas about air pressure.
Answer: pressure is called atmospheric pressure, or air pressure. It is the force exerted on a surface by the air above it as gravity pulls it to Earth. Atmospheric pressure is commonly measured with a barometer. ... Meteorologists describe the atmospheric pressure by how high the mercury rises.
