Question

1. practice: energy resources
2. practice: energy resources

respond to the following based on your reading.
question 1
what role does the sun play in allowing power to be produced with wind turbines?
question 2
how do hydroelectric dams emit greenhouse gases like methane without burning any fossil fuels?

Explanation:

The sun heats the Earth's surface unevenly. This causes differences in air temperature and pressure, leading to wind. Wind is then used to turn wind turbines for power generation. Hydro - electric dams can emit methane because the flooded vegetation in the reservoir decomposes anaerobically, producing methane as a by - product.

Answer:

Question 1: The sun heats the Earth's surface unevenly, creating wind that powers wind turbines.
Question 2: Flooded vegetation in the reservoir of hydro - electric dams decomposes anaerobically, emitting methane.
