Front

What is weathering by abrasion?

Back

Weathering by abrasion is the process of wearing down rocks and minerals through friction and impact caused by particles carried by water, wind, or sand.

Front

What are three methods scientists use to study Earth's climate history?

Back

Scientists study Earth's climate history by examining fossils, ice cores, and tree rings.

Front

What is a common characteristic of geothermal and solar energy?

Back

Both geothermal and solar energy do not produce greenhouse gases.

Front

How does hydropower generate energy?

Back

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

Front

What is true about oil, coal, natural gas, and uranium?

Back

They are all finite, or limited, non-renewable resources.

Front

Define renewable resources.

Back

Renewable resources are natural resources that can be replenished naturally over time, such as solar energy, wind energy, and biomass.

Front

What is the greenhouse effect?

Back

The greenhouse effect is the warming of Earth's surface due to the trapping of heat by greenhouse gases in the atmosphere.

Front

What is the role of fossils in studying climate change?

Back

Fossils provide evidence of past life and environmental conditions, helping scientists understand how climate has changed over time.

Front

What is acid rain?

Back

Acid rain is precipitation that contains high levels of sulfuric or nitric acids, often resulting from air pollution.

Front

What is the difference between renewable and non-renewable resources?

Back

Renewable resources can be replenished naturally, while non-renewable resources are finite and cannot be replaced once used.
