Answer the following question given this paragraph: There are very few gas molecules in the mesosphere. This means that there is little matter to absorb the Sun's rays and heat the air. Most of the heat that enters the mesosphere comes from the stratosphere below. That's why the mesosphere is warmest at the bottom. Q: Most of the heat that enters the mesosphere comes from where? A:

OPTIONS:
- Earth's surface
- Exosphere
- Troposphere
- the stratosphere

Answer: the stratosphere

Problem: OPTIONS:
- gravity
- velocity
- diffusion
- reflection
Q: Answer the following question given this paragraph: One thing is true of both regular and diffuse reflection. The angle at which the reflected rays leave the surface is equal to the angle at which the incident rays strike the surface. This is known as the law of reflection . The law is illustrated in the Figure below and also in this animation: http://www. physicsclassroom. com/mmedia/optics/lr. cfm.
