to make plastic. Coal is a solid mineral fuel that was very important in the past.

5
00:00:35,450 --> 00:00:42,810
We use coal to produce electrical energy in power plants and to make iron. Natural gas is a mixture

6
00:00:42,810 --> 00:00:52,270
of gases that is often found with oil. It is used as fuel to produce electrical energy in power

7
00:00:52,270 --> 00:01:00,990
plants and for cooking and heating our homes. Uranium is a white metal that is found in large

8
00:01:00,990 --> 00:01:09,650
amounts in the earth's crust. It is also very toxic. It is used in nuclear power plants

9
00:01:09,650 --> 00:01:13,409
to generate electrical energy. Bye bye!
