Question

4.

What renewable energy source utilizes Earth’s gravitational pull on water?
wind
solar
biomass
hydropower

Answer 1

The renewable energy source that utilizes Earth’s gravitational pull on water is hydropower.
Hydropower is generated by harnessing the energy of moving water, such as in a river or waterfall, to drive turbines that generate electricity. The gravitational pull of the Earth causes water to flow downhill, which can be harnessed to create electrical power. It is a clean and renewable energy source that does not produce greenhouse gases, and it is a significant source of electricity in many countries around the world.

Answer 2

hydropower

Step-by-step explanation:

Hydropower is the renewable energy source that utilizes Earth’s gravitational pull on water. It converts the energy from the falling or flowing water into electricity by using turbines and generators. The gravitational pull of the earth on water creates potential energy, which is then converted to kinetic energy as the water flows or falls, and finally, this kinetic energy is converted to electrical energy by hydropower plants. It is a clean and renewable energy source that doesn't produce harmful emissions and provides a reliable source of electricity to many parts of the world.
