There are a few different answers to this question, depending on what you are asking. I'll go over the main ones.
1. The Earth's axis is tilted in comparison to the Sun, so days get shorter in the winter months. This is due to less light, and therefore energy, hitting the Earth directly. Instead, that energy either misses entirely, or hits nearer to the Equator. This is why the poles have twenty-four hour days and nights depending on the season. (Night in the winter, day in the summer.)
2. In terms of the food chain, energy from the sun is converted to basic sugars by plants in a process known as photosynthesis, inside the plant's cloroplasts. Small animals such as mice and insects consume the plants, and the energy those plants converted from sunlight. This continues up the food chain until you get to apex-predators (tigers, bears, wolves, owls, etcetera).
3. In terms of electricity, solar panels are made of tons of 'solar cells' which tend to be lots of silicon atoms, which like to share electrons, and a conductive backing. (Pardon me if some of this section is incorrect, I only have a basic understanding of solar panels) When a photon (that is, a light particle) hits the silicon, it bumps off an electron, and the conductive backing catches it, resulting in a electrical current. This current is incredibly small per solar cell, so you need a ton of them to make any sort of useful power out of them. Solar panels do degrade over time, but incredibly slowly, there are some from the 1970's that still generate just as much power as they did originally (if not, only ever so slightly less).
I hope I answered what you needed to know! If you wanted a different answer, feel free to comment with some clarification and I would love to fill you in :)
Best describes Antarctica are known as reserves of oil and coal as well as mineral deposits in Antarctica.
<h3>What do you mean by Antarctica?</h3>
Antarctica is known as reserves of oil and coal as well as mineral deposits Antarctica although detailed knowledge of these mineral deposits.
There are deposits of minerals in Antarctica including coal and iron ore. Antarctica refers to the major source of oil and coal for the world.
Therefore, C is the correct option.

Krakatau volcano on 27 August 1883
Answer: 147 million km (happy to help)

Answer:
Step 1
Explanation:
Rocks that forms metamorphic rocks are not pushed to the earth surface. On the surface, the pressure and temperature conditions are not high enough to cause any metamorphic transformation in a rock.
Rocks must subside into deeper levels of the crust where mineral changes occur and hence new rocks called metamorphic rocks.
