What is the source of geothermal energy

The interior of the Earth is at a very high temperature. That heat from the core is the ultimate source of geothermal energy.

When the Earth was formed 4.8 billion years ago, the core was mostly molten iron and nickle. The energy to heat the core came from the gravitational energy present at the time of formation. Since then, additional heat energy has been added through nuclear decay of uranium and other heavy materials which were also included in the original formation process.

Which is a fossil fuel coal or oil

Both of them are because they evolved from little tiny creatures millions of years ago

What is the major source of air pollution today

the major source is the burning of fossil fuels

How does nuclear fission produce energy

A controlled nuclear chain reaction produces heat, driving steam turbines to produce energy.

In which decade were the first important laws passed to decrease water pollution

What is the law of the clean water act
rarrwwww
The clean water act is in act as of today. The clean water act is making sure every person has clean water to drink.
What is the most important law passed to deal with air pollution

most likely the Clean Air Act Answer: Like many milestones in human affairs the first was the most important since the first demonstrates that the law can do something about the problem, In the case of air pollution we have several choices: 300 CE: Roman law controls air emissions from certain industries in England 1272 CE: Use of Sea Coal banned by Edward I (and several folowing kings)

1895 CE: 1st US law against air pollution 1956 CE: British Clean Air Act 1963 CE: US Clean Air Act

What type of pollution did the clean water act succeed in limiting

Water Pollution.

Hybrid cars have 2 motors what are they

Electric and usually gasoline.

One problem with wind energy as a major source of electricity is

The problem with wind energy is that it does not produce much electricity. Wind does not flow at all places. So having wind energy as a major source of electricity is not a option.
