| What causes weather? | The uneven heating of Earth's ground and atmosphere |
| What is meteorology? | The study of the Earth's air, especially the movements and events that cause weather |
| Who studies meteorology? | A meteorologist |
| What is temperature? | The measurement of the amount of heat energy in the atmosphere |
| What tool do meteorologist use to measure air temperature? | A thermometer |
| What word do we use to describe the amount of water vapor that is in the air? | Humidity |
| What tool do scientist use to measure the amount of water vapor in the air? | A hygrometer |
| What is a front? | The boundary between air masses of different temperatures and humidity |
| What is an air mass? | A very large body of air that has about the same temperature and humidity through it |
| Describe a cold front. | When cold air pushes into warm air causing the warm air to rise quickly; this front produces thunderstorms, bringing fair, cooler weather. |
| Describe a warm front. | When warm air mass slides above a cold air mass producing light rain or snow, lasting for several days; when the front passes we will have warmer, more humid weather. |
| What tool do scientists use to measure the amount of rainfall? | A rain gauge |
| The weight of the air over a given spot is called _____. | air pressure |
| What tool do scientists use to measure air pressure? | A barometer |
| You are in a _____ pressure area when warm air presses down on the Earth's surface with less force. | low |
| What type of weather do low pressure systems usually produce? | Wet weather |
| You are in a _____ pressure area when cold air pushes down harder on the Earth's surface. | high |
| What type of weather do high pressure systems usually bring? | Pleasantly dry and cool weather |
| What is the movement of air from high to low pressure areas? | wind |
| What tool do scientists use to measure wind speed? | An anemometer |
| This type of cloud is fluffy and white with a flat bottom. It usually bring fair weather. | Cumulus cloud |
| This type of cloud is a smooth, gray cloud that covers the whole sky. It usually brings light rain and drizzle. | Stratus cloud |
| This type of cloud is feathery and made of tiny pieces of ice. It is associated with fair weather. | Cirrus cloud |
| This type of cloud looks like puffs of smoke. It usually brings thunderstorms. | Cumulonimbus cloud |
| Name four different types of precipitation. | Rain, snow, sleet, hail |
| What type of severe storm forms over land? | Tornadoes |
| What type of severe storm forms over water? | Hurricanes |
| _____ is the measure of the amount of heat energy in the atmosphere. | Temperature |
