This is rain, snow, sleet, or hail that falls from clouds to earth's surface.

This is the condition of the atmosphere at a certain time and place.

Millions of tiny water droplets or ice crystals.

This is water droplets formed when the air around the glass cooled to below the dew point.

This is the boundaries between air masses of different densities and different temperatures.

This movement is called the water cycle.

This is when the temperature happens at which the balance happens.

low ( 0 - 2000 mtrs. )
medium ( 2000 - 6000 mtrs.)
high ( above 6000 mtrs. )

This comes from the surrounding air.

It is a large body of air that has similar temperature and moisture content.

This is water that flows over land and into rivers, streams, and eventually the ocean.

Liquid water droplets on a surface or on tiny particles in the air.

Water; in any form. The four major forms are rain, sleet, hail, and snow.

The air must be saturated or have a relative humidity of 100%.

The less dense air mass rises over the denser air mass.

It may condense to form water droplets.

This depends on the rates of evaporation and condensation.

A lump of ice that falls from the sky.

A small temperature drop is needed for air to reach its dew point.

This forms when a cold air mass and a warm air mass go toward each other.

This change occurs when the sun's energy heats earth's surface.

It is that total part of the atmosphere pressure that is caused by vapor pressure

8000 mtrs

The temperature at which the rate of condensation equals the rate of condensation.

This forms when a warm air mass gets caught in between two cold air masses.
