How is the glass in a greenhouse similar to greenhouse gasses in the atmosphere? | They both allow light in and trap heat. |
Name some factors that could effect an areas climate? | Latitude, nearby oceans or mountains. |
Where should you go to stay safe in a tornado? | Get to low areas such as a basement or a cellar. |
There is a thunderstorm outside, would it be safe to hide inside a metal shed? | No! |
What are some of the effects of global warming? | Drought, melting glaciers, dramatic temperature changes |
What do weather maps use to show areas that have the same atmospheric pressure? | Isobar lines |
As altitude increases, what happens to the temperature? | The temperature decreases. |
What conditions will start a hurricane? | A low pressure area over warm ocean water. |
Why does water condense on the ground in the early morning? | The air temperature near the ground has reached its dew point. |
Name some adaptations that animals have developed to live in extremely cold regions? | Hibernation, thick fur, |
What will happen when an area reaches 100% humidity? | Water vapor will condense into water drops |
What is the term used to describe the specific temperature at which water vapor begins to condense to into liquid water? | The dew point |
