Answer:
Choice B., infrared radiation
Explanation:
A gas in atmosphere which allows the incoming of the solar radiation to reach Earth's surface and on the other hand also absorbs these radiation which are re-emitted as heat, trapping heat in atmosphere and causing temperature to rise is called green house effect.
<u>For example, carbon dioxide is a greenhouse gas which traps heat from sun resulting in the warming the planet
.</u>
<u>Thus, infrared radiations which is a source of heat is reflected back to the Earth’s surface by greenhouse gases.</u>
Answer:
Sunlight penetrates the top layers of the ocean, so photosynthesis occurs there.
Explanation:
It's a chemical change. In synthesis you add compounds which form new ones. This means that it cannot be a physical or phase change because you form something new. Not all synthesis and decomposition reactions use nuclear energy therefore it is a chemical change.
