i have this thing for science and the teachers asked us to do something on "climate change"
what does she mean by:: what are thr renewable energy sources?
Id really appreciate it if you helped:)

Answer 1

climate change! i think ur teacher perhaps talking about climate which is nowadays getting warmer....something like global warming! but i m not sure about it.

Answer to ur second question is.....
Some resources are such as plants (crops, forests) and animals are replaced from time to time b'coz they have a life cycle, and continuous harvest is possible. These resources are said to be renewable.

Renewable sources are of conventional types, such as forests, crops, other plants, wild life and aquatic resources; and non conventional types, such as solar energy, wind energy, wave & tidal energy, biogas, atomic energy, and so on.
These resources can also be grouped as water resources, energy resources, agriculture, rangelands, forest resources, wild life, aquaculture, etc.

Answer 2

Renewable energy sources is energy that can be replenished at the same time as it gets used. Unlike fossil fuels they have no detrimental effects on the environment. Examples are solar and wind energy

Answer 3

Well I don't think they know what they are talking about.The earth has been recycling the fossil fuels for a million years . I think they have a misunderstanding of how mother does it. A tree or any plant starts the recycling of our air and they like the CO2 that we produce. The plants take in CO2 and put out oxygen,that is part of it. The CO2 branch of the recycling is the tree growing and shedding its leaves and they wash down to the delta where it decomposes into gas,oil,and coal. do u think u can recycle better?

Answer 4

Wind, Water, Solar, Geothermal, Wood, etc. She means what materials are able to be recycled and used as energy at the same time.
