| A | B |
|---|
| Oceans... | store and transfer more heat than the continents |
| Oceans... | warm up and cool down slowly |
| Oceans.. | moderate temperatures of surrounding areas |
| air mass | a large boy of air that has the same properties as the Earth's surface over which it develops |
| Precipitation and storms occur | when warm and cold air masses meet |
| High pressure systems... | have decreasing cloudiness because the sinking of cold air makes it difficult for warm air to rise, cool and condense |
| Low presure systems | have cloudy weather because higher temperatures warm the ground and surrounding air which rises, cools and condenses to form clouds |
| A tornado happens when... | wind at differnt heights blows in different directions and at different speeds over land |
| A tornado is... | a violently rotating column of air in contact with the ground |
| A hurricane forms when | warm, moist air rises quickly over the ocean causing a strong, whirling storm with high winds and heavy rains |
| Three factors that impact the development of a storm when two air masses meet | Differences in moisture; air pressure; temperature |
| The main factor that impacts the development of wind is... | atmospheric pressure |
| What is the underlying reason for major systems such as hurricanes, tornadoes, and thunderstorms | The Earth is trying to redistribute its heat by moving air |
| Where do tropical storms begin | over water near the equator because tropical stroms are fueled by warm water |
| Coriolis effect is... | the rotation of the earth's surface causing wind systems to curve. |
| What are the forces that cause weather? | air, water and the sun |
| Two ways in which energy from the Sun is distrubuted around Earth is... | radiation and convection |
| Climate | the weather of a region averaged over a long period of time |
| How does wind move between Low and High pressure areas | it moves from areas of high pressure to areas of low pressure |
| What area of the Earth receives the most direct sunlight? | Area around the equator (middle) |
