Water in the Atmosphere and Precipitation

2. rain that falls through a 0 degrees C layer and freezes in particles smaller than 5 millimeters in diameter.
4. rain that freezes over when it hits the ground, due to cold surfaces.
6. Look fluffy and round. Usually signs of fair weather.
7. Water vapor in a cloud that is converted directly into ice crystals. In endless shapes and patterns.
8. A measure of the amount of water vapor in the air.
9. Wispy, feathery clouds and found in low temperatures. Clouds are made up mostly of ice cubes.
11. Long periods of unusually low precipitation.
12. Towering clouds with flat tops that often produce thunderstorms.
13. Form in flat layers. Usually cover most of the sky. Status clouds can thicken and produce drizzle, rain or snow.
14. Any form of water that falls from the clouds and reaches the Earth's surface.

1. The temperature at which condensation begins.
3. Drops of water that are at least 0.5 millimeters in diameter.
5. The percent of water vapor in the air compared to the maximum amount the air can hold.
8. Round pellets of ice larger than 5 millimeters in diameter. Forms inside cumulonimbus clouds during a thunderstorm. Layers of ice build up on each pellet in cold regions of the clouds until it is heavy enough to fall to the ground.
9. The process by which molecules of water vapor in the air become liquid.
10. the process by which water is converted from its liquid form to its vapor form and thus transferred from land and water masses to the atmosphere.
15. A prefix added that means that a cloud will produce snow or rain.
