| Question | Answer |
|---|---|
| Explain the process of condensation. | Water vapor cools and changes from a gas to a liquid which create clouds. |
| What are the three main types of clouds and describe them? | Cumulus- low altitude, flat bottoms, fluffy tops Stratus-low altitude, flat, layered, spread all over sky Cirrus-high altitude, thin, feathery, “wispy” |
| What type of cloud produces thunderstorms and tornadoes? | Cumulonimbus |
| How are air masses mainly classified? | humidity and temperature |
| Compare and contrast a continental tropical air mass and a continental polar air mass. | Continental tropical- dry (over land), warm, low pressure Continental polar- dry (over land), cold, high pressure |
| Compare and contrast a maritime tropical air mass and a maritime polar air mass. | maritime tropical- moist (over water), warm, low pressure maritime polar- moist (over water), cold, high pressure |
| Where do maritime air masses form compared to continental air masses? | Maritime air masses form over the ocean. Continental air masses form over land. |
| What kind of air mass would form over Atlanta, Georgia? | continental tropical |
| What kind of air mass would form over the Gulf of Mexico? | maritime tropical |
| What is a front? | An area where two air masses meet and do not mix together. |
| What is the funnel-shaped cloud that reaches the surface of the Earth called? | Tornado |
| What happens when a hurricane moves over land? | It will weaken due to the energy lost and it usually will bring winds and rain |
| Where do hurricanes form? | Over warm water (usually near areas by the equator) |
| Where does a hurricane get its energy? | From warm water and humid air |
| What is the area where the temperatures are the warmest with low pressure and no winds during a hurricane called? | The eye |
| How do thunderstorms form? | Warm air is quickly forced upward during a cold front, creating cumulonimbus clouds. |
| What two main factors determine climate of an area? | Temperature and precipitation |
| What causes a flood and which type of storm can lead to flooding? | Floods occur when the ground cannot absorb any more water, so it builds up on the surface. Hurricanes can cause flooding because of the excessive rain. |
| When does lightning mostly occur? | Lightning is a sudden spark as energy jumps between thunderclouds-cumulonimbus, mostly during thunderstorms. |
| What type of clouds form as a cold front develops? | cumulonimbus |
| How does unequal heating of Earth’s surface cause tornadoes? | When a cold air mass runs into a warm air mass it forces the warm air mass upward creating cumulonimbus clouds, as a cold front occurs. The clouds spin because of winds, created by differences in the air pressures due to the unequal heating. |
| What type of air would affect the northern part of the United States during the winter? | Cold, dry air |
| Which air mass would form over the coast of southern California? | Maritime tropical |
| What occurs at a cold front? | A cold air mass runs into a warm air mass and violently pushes the warm air mass upward. This can create cumulonimbus clouds and could produce thunderstorms and tornadoes. |
| What occurs at a warm front? | A moving warm air mass rises over a cold air mass. |
| What occurs at a stationary front? | A cold air mass and warm air mass collide and neither have enough force to push the other one, so they have a standoff (both stay there) resulting in days of cloudy weather or precipitation. |
| What occurs at an occluded front? | Two cold air masses move towards each other and they trap a warm air mass in the middle. The warm air mass is pushed upward and is cut off from the ground. |
