Your science teacher gives you a glass jar filled with water, organic material, dirt, and small rocks. She asks you to shake the jar for one minute and allow it to rest overnight
How does this experiment prove the composition of soil?
A
All materials will remaindhoxed with the water in the glass jar
B
The particles will settle into layers with organic material on the top and rocks on bottom
с
The particles will settle into layers with rocks on the top and organic material on the top
D
The rocks will settle on the bottom and all other particles will remain mixed with the water.
Answer: B. The particles will settle into layers with organic material on the top and rocks on bottom
Explanation:
Soil contains different particles in it from various types of souls such as sand and silt to organic material. These particles have different weights and sizes and so can be separated by the glass jar experiment above.
With soil having larger particles. They will appear in the bottom of the jar and but the top will have decaying and partially decayed material.
A student reads the following statement.
The presence of greenhouse gases in Earth's atmosphere is important to Earth's ability to support human life.
How would Earth be different without greenhouse gases in its atmosphere?
A. More heat from solar radiation would escape into space.
B. More solar radiation would be reflected back into space.
c. More solar radiation would penetrate Earth's crust and mantle.
D. More beat from solar radiation would be stored in Earth's core,
The correct answer is A. More heat from solar radiation would escape into space.
Explanation
Greenhouse gases are a set of gases present in the earth's atmosphere that have the function of regulating the temperature by retaining and radiating heat energy. One of the sources of heat energy for greenhouse gases is radiation from the sun, which reaches planet Earth, passes through the atmosphere, and reaches the earth's surface where a part is reflected out of the atmosphere and another part is retained and irradiated by greenhouse gases in different directions, being retained between the atmosphere and the earth's surface, contributing to temperature regulation. Therefore, the correct answer is A. More heat from solar radiation would escape into space.
