Answer:

Explanation:
An element only has <u>one</u> type of atom and cannot be broken down by chemical means.
Let's analyze the answer choices.
1. This has two types of atoms, so it cannot be an element. It has more than one type of atom.
2. This has two types of atoms that are bonded together. It cannot be an element because there is more than one type of atom and the bonds can be broken.
3. This has one type of atoms, so it is an element.
Therefore the best answer choice is 3.
When it nears the sun, due to the power of solar wind
Answer:
It can reduce carbon in the atmosphere.
On the earth surface
Explanation:
The long-wavelength radiation is created on the earth surface when electromagnetic radiation is re-emitted.
- The sun releases radiation in form of short-wave.
- They are usually more energetic and with short wavelength and a high frequency.
- When they interact with materials on the earth, they are radiated back as long-wavelength radiation that usually causes heat.
- Ultraviolet rays and other high energy waves are emitted from the sun because it is a very hot body.
- When these radiations enters the earth, they are re-radiated back as long waves with lower energy.
- Earth is cooler than the sun
- When some of the short waves for example, the ultraviolet rays gets to the surface, it is absorbed and re-radiated back.
- When the short waves are absorbed, they lose some of their their energy to the earth surface.
- The remainder is radiated back as less energetic long waves.
- The hotter a body is, the more energetic the radiation it releases.
