- Evaporation
- The process by which water molecules in liquid water escape the hydrosphere & causes the air to rise as water vapor.
- cirrocumulus
- This cloud tells us storms are on the way
- frost
- process by which molecules of water vapor become liquid water
- Condensation
- The process by which molecules of water vapor in the air cool and become liquid water.
- cumulonimbus
- This cloud produces thunderstorms
- hail
- ice pellets that add layers of ice as they are carried up and down in a cumulonimbus cloud.
- nimbostratus
- This cloud produces drizzle, rain, or snow
- Humidity
- The amount of water vapor in a given volume of air.
- Dew point
- The temperature at which air is saturated and condensation forms.
- Cirrus
- Wispy, feathery clouds made of ice crystals that form at high levels.
- precipitation
- Any form of water that falls from clouds and reaches earths surface
- Relative humidity
- The percentage of water vapor in the air compared to the maximum amount of water vapor that air can contain at a particular temperature.
- freezing rain
- raindrops that freeze after they hit the ground or other cold surfaces
- cumulus
- This cloud produces fair weather
- drought
- Long periods of unusally low precipitation
- Water cycle
- The Continental movement of water among Earth's atmosphere, Oceans, and land surface through evaporation, condensation, and precipitation.
- rain gauge
- Meteorologists collect rainfall with this.
- dew
- water that condenses from the air onto a cooler surface
- Stratus
- Clouds that form in flat layers and often cover much of the sky.
- sleet
- raindrops that freeze into tiny particles of ice as they fall through the air.
- Cumulus
- fluffy white clouds usually with flat bottoms that look like cotton.
- snow
- water vapor that's in a cloud is converted directly into ice crystals.
