Human Impact Study Guide (24/25)

Front

What is geothermal energy?

Back

Geothermal energy is a renewable energy resource that comes from the heat stored beneath the Earth's surface.

Front

How does hydropower generate energy?

Back

Hydropower generates energy by using the motion of water in a dam to turn turbines.

Front

What happens to sea levels as global temperatures rise?

Back

As global temperatures rise, sea levels are expected to increase due to melting glaciers and thermal expansion of water.

Front

Why are oil, natural gas, and coal considered nonrenewable resources?

Back

These fuels are considered nonrenewable because they are available in a limited supply, and once used, they cannot be replenished.

Front

What is the impact of melting glaciers on sea levels?

Back

Melting glaciers contribute to rising sea levels as they release freshwater into the oceans.

Front

What is the definition of renewable energy?

Back

Renewable energy is energy that comes from resources that are naturally replenished, such as sunlight, wind, and water.

Front

What is the main cause of climate change?

Back

The main cause of climate change is the increase in greenhouse gases in the atmosphere, primarily from human activities like burning fossil fuels.

Front

What are greenhouse gases?

Back

Greenhouse gases are gases that trap heat in the atmosphere, contributing to the greenhouse effect. Examples include carbon dioxide and methane.

Front

What is the greenhouse effect?

Back

The greenhouse effect is the process by which certain gases in the Earth's atmosphere trap heat, keeping the planet warm.

Front

What is the role of permafrost in climate change?

Back

Permafrost, when thawed, releases greenhouse gases like methane, which can further accelerate climate change.
