Answer:
Geo thermal : Nuclear reactions
Bio mass : plants
Solar : sun rays
Hydro power : Water
Explanation:
Geothermal energy is also used to directly heat individual buildings and to heat multiple buildings with district heating systems. Hot water near the earth's surface is piped into buildings for heat. A district heating system provides heat for most of the buildings in Reykjavik , Iceland.
The major biomass sources currently used are sugar cane and corn to produce bioethanol , and rapeseed for biodiesel production.

Answer:
The use of music
Explanation:
<em>The independent variable in the example is the use of music.</em>
The independent variable in research or experiment is a variable whose value is not affected by any other variable. That is, the value of an independent variable is not influenced by any other variable.
<u>In this case, the use of music stands alone and is not influenced by any other variable in the experiment. In actual fact, the use of music's effect is being tested in the experiment and hence, is not in itself influenced by any other variable.</u>
