Environmental Science Ch. 3 Review

Front

What layer is above the troposphere?

Back

Stratosphere: The second layer of Earth's atmosphere, located above the troposphere and below the mesosphere, characterized by a temperature increase with altitude.

Front

What is the relationship between earthquake magnitudes?

Back

An earthquake of magnitude 7 is 31.7 times stronger than an earthquake of magnitude 6. This is due to the logarithmic scale used to measure earthquake magnitudes.

Front

Which of the following is NOT an abundant greenhouse gas?

Back

Ozone: While ozone is a greenhouse gas, it is not as abundant as carbon dioxide, methane, or nitrous oxide in the atmosphere.

Front

Where are most of Earth's active volcanoes located?

Back

Around the Pacific Rim: This area, also known as the Ring of Fire, is where a large number of earthquakes and volcanic eruptions occur.

Front

What do plants need like organisms need water?

Back

Sunlight: Plants require sunlight for photosynthesis, which is essential for their growth and energy production.

Front

Define greenhouse gases.

Back

Greenhouse gases are gases in Earth's atmosphere that trap heat, including carbon dioxide, methane, and nitrous oxide.

Front

What is the function of the stratosphere?

Back

The stratosphere contains the ozone layer, which absorbs and scatters ultraviolet solar radiation, protecting living organisms on Earth.

Front

Explain the significance of the Pacific Ring of Fire.

Back

The Pacific Ring of Fire is significant due to its high levels of tectonic activity, including earthquakes and volcanic eruptions, affecting global geology.

Front

What is the difference between weather and climate?

Back

Weather refers to short-term atmospheric conditions, while climate is the long-term average of weather patterns in a specific area.

Front

What role do plants play in the carbon cycle?

Back

Plants absorb carbon dioxide during photosynthesis, helping to regulate atmospheric CO2 levels and providing oxygen as a byproduct.
