| What region has forests and plenty of rain fall all year? | rain forest |
| What do all three temperate marine climates have in common? | They all have mild winters. |
| What is the gradual increase in the temperature of the atmosphere? | global warming |
| What type of climate would you be likely to live in if you lived far from an ocean? | continental |
| What are the characteristics of summer? | longer days and more direct rays from the sun |
| What type of climate do the Great Plains and the Rocky Mountains have? | semiarid |
| Finish this sentence: If an organism today needs certain conditions to live, then a similar organism that lived in the past... | needed similar conditions |
| What happens to the sea level during an ice age? | It lowers. |
| What has happened to the level of carbon dioxide in the atmosphere over the past 200 years? | increased steadily |
| What does the ozone layer do? | filter harmful ultraviolet radiation from the sun |
| What do the chlorine atoms in the statosphere do to the ozone? | break the O3 (ozone) into oxygen (O2) |

| Into what 2 states did the most recent major ice age extend? | Iowa and Nebraska |
| How can continental movements cause climate changes? | When continents move, land and sea move causing changes in winds and ocean currents which causes climate change. |
| How might carbon dioxide cause global warming? | by trapping more heat in the atmosphere |
