Earth's Changing Climate Test Review

What is the greenhouse effect?

• a process where gasses in earth's atmosphere absorb energy to keep earth warm

• a process where carbon is stored in plants and later released as sugars

• a process where ice melts and polar bears lose their habitats

• a process where sunlight is absorbed by oceans and released as infrared energy

Answer explanation

The greenhouse effect is what keeps earth warm and liveable. Greenhouse gases like carbon dioxide and methane absorb infrared energy, keeping more energy in the Earth system. More energy in the earth system leads to warmer temperatures.

This graph of Global Average Surface Temperature shows...

• fluctuations, but no real trend

• a positive or increasing trend

• a negative or decreasing trend

Answer explanation

Trends are patterns in data over long periods of time.

Fluctuations are variation, or changes, in data.

What does carbon dioxide do in the atmosphere?

• allows condensation and cloud formation to occur

• causes a chemical reaction between ozone and oxygen

• absorbs infrared energy, keeping it in the earth system longer

• absorbs sunlight energy, keeping it in the earth system longer

Earth's atmosphere is made of different gases that can affect Earth's climate in different ways.

• True

• False

Answer explanation

Carbon dioxide, methane, and water vapor are greenhouse gases that absorb energy and keep it in the Earth system. This can allow temperatures to increase. Not all gases absorb energy though.

Climate is affected by how much energy is in the Earth System.

• True

• False

Answer explanation

Since energy affects temperature (more energy = warmer temperatures), the amount of energy in the atmosphere and earth's surface determines climates.
