Weather
Thin and wispy looking, almost like someone pulled them apart. These clouds usually mean good weather.

An anemometer
The breakdown and wearing away of rock through long exposure to wind, water, heat, and cold.
Weathering
Look like a huge gray blanket that lay low in the sky. These clouds usually mean rain is coming.
Stratus clouds
A mass of cool air moving toward a warmer air mass.
A cold front
Water falling to the earth in the form of rain, sleet, hail, or snow.
Precipitation

A Front
When water changes from a gas to a liquid. It happens when water vapors get cold.
Condensation
An instrument used by scientists to measure the amount of rain or other forms of precipitation.

Erosion
White puffy clouds that look like they are piled up on top of each other. These clouds are a sign of good weather.
Cumulus clouds
What the weather is like for a certain area over a long period of time is called...

All of the gases (air) that surround the Earth
The atmosphere
Condensed water vapors in the atmosphere. They form when tiny drops of water and ice join together in the sky.
Clouds
A map or graph that is used to record the weather. They can show weather patterns and trends.
