Question 2 (1 point) Which renewable energy source harnesses the Earth's internal heat? - Geothermal energy Ob Solar active systems C Biomass energy d Tidal energy

## Step 1<br />The question is asking us to identify the renewable energy source that harnesses the Earth's internal heat. The options provided are Geothermal energy, Solar active systems, Biomass energy, and Tidal energy.<br /><br />## Step 2<br />Geothermal energy is the energy that is derived from the heat stored within the Earth. This heat is generated by the decay of radioactive isotopes and the compression of the Earth as it cools. This heat is then harnessed to generate electricity and heat.<br /><br />## Step 3<br />Solar active systems, on the other hand, harness the energy from the sun. This is not the Earth's internal heat, but rather the heat from the sun.<br /><br />## Step 4<br />Biomass energy is derived from organic materials such as plants and animals. This is not the Earth's internal heat, but rather the energy from organic materials.<br /><br />## Step 5<br />Tidal energy is derived from the gravitational pull of the moon and the sun on the Earth's oceans. This is not the Earth's internal heat, but rather the energy from the gravitational pull of the moon and the sun.
