Take A Short And Easy Trivia Quiz On Earth Science!

1. A system is shut off from the enviroment.

The correct answer is "closed" or "close". This suggests that the system is not open or accessible to the environment. It is likely sealed or shut off in some way, preventing any interaction or exchange with the surrounding environment.

2. Which of the following is NOT one of Earth's four spheres?

Lithosphere

Ecosphere

Hydrosphere

Biosphere

The correct answer is Ecosphere. The ecosphere is not one of Earth's four spheres. The four spheres are lithosphere (which includes the solid outer layer of the Earth), hydrosphere (which includes all water on Earth), atmosphere (which includes the air and gases surrounding Earth), and biosphere (which includes all living organisms on Earth). The ecosphere is not a recognized scientific term or sphere.

The correct answer is Ecosphere. The ecosphere is not one of Earth's four spheres. The four spheres are lithosphere (which includes the solid outer layer of the Earth), hydrosphere (which includes all water on Earth), atmosphere (which includes the air and gases surrounding Earth), and biosphere (which includes all living organisms on Earth).

3. From solid to water is.....

Sublimation

Deposition

Condensation

Evaproation

Condensation is the process in which a gas or vapor changes into a liquid. In this case, the question is asking about the change from a solid to water, indicating that the solid is being converted into a liquid form. Sublimation refers to the direct change from a solid to a gas without going through a liquid phase. Deposition is the reverse process of sublimation, where a gas changes directly into a solid. Evaporation refers to the change from a liquid to a gas. Therefore, the correct answer is condensation.

4. Reflection bounces off as to absorption .

When light or sound waves hit a surface, they can either bounce off or be absorbed by the surface. In this case, the correct answer is "takes it in, absorbs" because it suggests that the surface is absorbing the reflection rather than reflecting it back.

7. When is the earth farthest from the sun?

June

April

January

July

The earth is farthest from the sun in July. This is because the earth's orbit around the sun is not a perfect circle, but rather an ellipse. The point in the orbit where the earth is farthest from the sun is called aphelion, and it occurs in July. In contrast, perihelion, the point where the earth is closest to the sun, occurs in January.
