Multiple Choice

What happened to the polar bear’s habitat as you played the game?

• Carbon raining down increased the amount of ice and improved the habitat for polar bears.

• Carbon raining down caused flooding and the loss of habitat for polar bears as the ice melted.

• Oxygen raining down caused flooding and the loss of habitat for polar bears sea levels rose.

• Carbon raining down caused flooding and the loss of habitat for polar bears as sea levels rose.

Fill in the Blank

The Earth can be thought of as a collection of different systems like the atmosphere, the water on our planet, the _______, and all living things.

Multiple Choice

When the amount of water in the oceans changes it can affect the land and then living things

• True

• False

Multiple Select

Select all the correct statements

• Increased carbon dioxide in the atmosphere is trapping more heat and causing rising global temperatures.

• Increased carbon dioxide in the atmosphere is trapping more heat and causing falling global temperatures.

• Earth supports life ibecause the average global temperature is “just right,” not too hot and not too cold.

• Earth’s atmosphere contains gases that create a greenhouse effect

Reorder

Reorder the following to reflect the pathway to the GreenHouse effect

• the Sun shines down through the atmosphere of invisible gases to Earth’s surface

• the Earth warms

• some of the thermal energy (heat) radiates back toward space—some escapes

• some is trapped by special gases in the atmosphere that absorb thermal energy

• these gases are called greenhouse gases because they act like the glass on a greenhouse to trap thermal energy.

Multiple Choice

The main greenhouse gases in Earth’s atmosphere are ​ ​ ​ ​

• carbon dioxide
• nitric acid
• greenhouse gases
• fossil fuels
• natural gas

Multiple Choice

Greenhouse gases are necessary to maintain Earth’s average temperature.

• TRUE

• FALSE

Multiple Choice

______ occurs when more of the thermal energy from the Sun remains within Earth’s atmosphere, resulting in rising global temperatures.

• the enhanced greenhouse effect

• the burning of fossil fuels

• greenhouse effect

Fill in the Blank

Precipitation, including rain and snow, results when water __________from bodies of water such as the oceans, rivers, and lakes.

Reorder

Reorder these into logical cause and effect statements.

• As the Earth’s bodies of water absorb more thermal energy, the temperature of the water increases.

• This increases the rate of evaporation and results in more water vapor in the atmosphere.

• As the water vapor rises in the atmosphere, it cools and condenses to form clouds and, ultimately, precipitation.

• False

Multiple Select

Choose all the correct answers.

• Corals are important because and protect the land from being eroded by waves

• Corals grow along the coastlines of land

• Corals are important because they can be used to make jewelry.

• Corals provide habitats for marine organisms.

Fill in the Blank

Most coral reefs grow where ocean ____________ are relatively warm and corals can get plenty of sunlight.

Fill in the Blank

The algae capture sunlight and produce ____ for the corals through photosynthesis.

Multiple Choice

Corals can survive coral bleaching events and obtain new algae.

• True

• False

Reorder

How coral bleaching occurs

• corals become stressed when ocean water temperatures increase

• corals eject the algae that live in them

• when corals lose their algae, they lose their food source

• and they also lose their color
