What are the sources and any problems associated with 1) fossil, 2) nuclear, and 3) renewable fuels?
Evgesh-ka [11]

Answer:

<u>Fossil fuel- </u>The sources of fossil fuels are directly from the plants and animals, that are buried millions of years back and are converted into fossil now.

The consumption of fossil fuel leads to the emission of carbon into the atmosphere that is responsible for the increasing global temperature. This is one of the major problem of fossil fuel use.

<u>Nuclear fuel-</u> Nuclear fuels are derived from the radioactive elements such as uranium, strontium and potassium.

One of the major problem of using nuclear fuel is that it releases radioactive waste, that are harmful for various life forms.

<u>Renewable fuels-</u> This are renewable energy that can be generated again and again and are directly derived from the wind, water and the sun. For example, wind mill, solar panels and dams.

One problem of renewable fuels is that it has a lower production of energy such as electricity in comparison to the fossil fuels.

what would happen if igneous rock was first exposed to energy from the sun and then millions of years later to energy from Earth
inysia [295]

Answer:They would become igneous rocks

Explanation:

If originally, sedimentary rocks are exposed to energy from the sun, no changes will occur to them.

One will hardly spot any difference in their mineralogical composition as such.

The temperature of the sun does not any significant alteration on earth materials.

The heat from the interior has a very significant effect on rocks, especially sedimentary rocks.

Heat from the interior can reach a staggering 6000°C which is more than enough to cause a metamorphic change in a body rock.

In fact, at this temperature, igneous rock will be produced from the sedimentary rock.
