What are the energy sources responsible for cycling matter through the living and non living components on earth?
your butt hole and you jk i got no clue
How is nuclear energy and fusion energy different?
Nuclear energy as we use it now is from nuclear fission. Nuclear fusion is the joining up of nuclei rather than the splitting (fission), but it is not yet available on Earth.
How is the suns energy classified?
Energy sources can be classified into two types: nonrenewable and renewable. Nonrenewable resources, such as fossil fuels and nuclear material, are removed from the earth and can be depleted. These resources have been the most used type of energy in the modern era. The source of energy that does not replenish in nature is known as non-renewable source of energy. Coal, petroleum, natural gas, etc. are some of the examples of non-renewable sources of energy. (b) Exhaustible sources are those sources of energy, which will deplete and exhaust after a few hundred years. An ideal source of energy should possess the following characteristics. (a) It should be capable of giving an adequate amount of useful energy. (b) It should be convenient to transport, store and use. (c) It should be economical. It does a huge amount of work per unit mass. It is easily accessible. It is easy to store and transport. It is economical.
What 2 places on early earth could organic molecules been synthesized?
Two hypotheses about the source of organic molecules on Earth would be, first, that they formed out of the original chemical composition of the planet, because of the energy provided by solar radiation and lightning, and second, that they were already present in interstellar dust clouds and therefore were part of the original composition of the Earth when it condensed out of an interstellar dust cloud.
How are thermal pollution and global warming related?
Net heat is generated on earth by liberating energy from stored energy sources (coal, oil, gas, nuclear, etc). All heat generation warms the earth. Nordell estimates this accounts for 73% of observed warming.
How did the three sources of heat prevent life from existing when the earth was formed?
the first sources of heat was asteroids and meteorites. another sources of heat for the early earth was the contraction of gravity. the third sources of energy for the early earth was radioactivity. hope this helped :)
Which of earth's early sources of heat are not major contributors to earth's present-day internal energy?
The sun
Earth's energy sources?
There are many of energy sources in earth like solar energy, geothermal energy, hydroelectricity, tide energy, nuclear energy.
What are the two source of energy that power the earths system?
The sun and the earth's interior are the two sources of energy that power earth's systems.
What are the two sources of that power earths energy?
The sun and the earth's interior are the two sources of energy that power earth's systems.
What are the sources of energy that power the earths systems?
The sun and the earth's interior are the two sources of energy that power earth's systems.
What are two sources of energy that power earths system?
The sun and the earth's interior are the two sources of energy that power earth's systems.
Energy can enter the earth system from internal sources through convection and from external sources through what?
Energy can enter the earth system from internal sources through convection and from external sources through radiation from the Sun (solar energy).
What are two sources energy for the earth system?
Matter and energy
What are earth's internal energy sources?
pressure
What were some of the heat sources for early earth?
yea
What were the sources of heat for the protoplanet?
the sources of heat is the sun and the solar system this makes the earth have heat and energy. The sun is the earth main source of heat and energy
