Chapter 16
| Question | Answer |
|---|---|
| What is weather? | The state of the atmosphere at a specific time and place. |
| What is humidity? | The amount of water vapor present in the air. |
| What is relative humidity? | A measure of the amount of water vapor present in the air compared to the amount needed for saturation at a given temperature. |
| What is dew point? | The temperature as which the air is saturated and condensation occurs. |
| What is fog? | Low level stratus clouds near the ground |
| What are the different heights of clouds? | Strato - low; Alto - Middle; Cirro - High |
| What are the different shapes of clouds? | Stratus, Cirrus, Cumulus |
| What is precipitation? | When moisture condenses out of air and falls to ground as rain, sleet, snow or hail. |
| What is a tornado? | A violent, whirling wind that moves in a narrow path over land |
| What is an air mass? | A large body of air with similar temperature and moisture. |
| What is an isobar? | A line that connects points of equal pressure. |
| What is an isotherm? | A line that connects points of equal temperature. |
| What are the characteristics of a cumulus cloud? | Puffy, white clouds that look like cotton balls |
| What are the characteristics of a cirrus cloud? | High, white feathery clouds usually associated with fair weather. |
| What are the characteristics of a stratus cloud? | Clouds that look like layers of sheets |
| What does a meteorologist do? | A person who forecasts the weather using data collected from many sources. |
| What type of cloud does a tornado form from? | Cumulonimbus cloud called a wall cloud |
| Where do hurricanes form? | Over tropical areas |
| What is sleet? | Rain that passes through a layer of freezing air near the ground |
| How does snow form? | Forms when water vapor changes directly into a solid. |
| One place where low pressure systems form? | Along fronts. |
| How does a cold front form? | A cold air mass approaches a warm air mass pushing the warm air mass up causing clouds to form and possibly strong storms. |
| How does a warm front form? | A warm air mass approaches a cold air mass pushing the cold air mass down causing stratus clouds to form and possibly a steady rain. |
| How does lightning form? | Forms when current flows between regions of opposite electrical charges. |
| How does thunder form? | A result of lightning, the air is super heated causing to expand then contract causing a sound wave. |
| What is hail? | Precipitation that forms in lumps of ice. |
| How do hailstones grow? | They grow larger as they're tossed up and down by rising and falling air. When large enough they fall to the ground. |
