How is energy from the sun distributed around earth?
amm1812
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 :)

Write the basic and simplified form of energy system in the atmosphere?
Margaret [11]

Answer:

An energy system is a system primarily designed to supply energy-services to end-users.[1]:941 Taking a structural viewpoint, the IPCC Fifth Assessment Report defines an energy system as "all components related to the production, conversion, delivery, and use of energy".[2]:1261 The field of energy economics includes energy markets and treats an energy system as the technical and economic systems that satisfy consumer demand for energy in the forms of heat, fuels, and electricity.[1]:941

Which of the following is NOT part of the definition of a mineral? Select one: a. Has a specific chemical composition O b. Has a
Kay [80]

Answer:

The following is NOT part of the definition of a mineral: c. can be produced by natural or laboratory processes. Is glacial ice a mineral? d. Yes. Which type of bonds results when two atoms share electrons? d. Covalent

Explanation:

Mineral are composed of specific chemical elements. The are organized and their atomic structure forms crystals. They occur naturally and they are associated with rocks. The reason why they are inorganic is because they do not contain carbon, however, they can be produced by organic processes. Therefore, c. is NOT part of the definition of a mineral.  Following the same principles, ice is considered a mineral because it is composed of one single chemical molecule (H2O), it occurs naturally and it contains a well organized crystal structure. The process of sharing two atoms is called covalent bond. In an ionic system, the electron is transferred to another atom so the concept of sharing is limited to the covalent bond.
