Cirrus Clouds Above 6000 m Means “curly” ice crystals
Cirrus Sunlight passes through easily
Cirrocumulus Form before or after a snowfall or rainfall.
Cirrostratus Halo appearance around sun or moon. Bending of light rays as they pass through the ice crystals. May thicken and lower to turn into altostratus clouds.
StratusClouds Means “sheet-like” or “layered” low clouds Form when warm, moist air lies below a layer of cold air. Often block out sun. Cover large areas.
Nimbostratus Nimbo means “rain” Bring heavy rains or snow.
Cumulus Means “piled” or “heaped.” Form due to warm, moist air rises and cools. Height of cummulus depends on speed of upward movement and moisture in the air.
Cumulus Lots of moisture rises.
Billowing Cumulus Will develop into a cumulonimbus cloud.
Cumulonimbus Thunderhead Rain Lightning Thunder
Fog Low level stratus cloud. Radiation fog or “ground fog.
Steam Fog Fog over James River. Land on other side of bridge, no fog. Forms near lakes or rivers where cool air meets warm water.
Upslope fog Forms when air cools as it rises along landslopes.
Advection Fog Warm moist air goes over cool land.

Clouds and Weather Predictions 5 th Grade Science.
Earth Science Hook. Clouds How do Clouds Form? In order for clouds to form you need the following: – Low Pressure – Relatively “humid” air – Condensation.
Up in the clouds …. How are clouds formed? Warm moist air rises because it is less dense. As it rises it cools and becomes more dense so it can’t hold.
Clouds Water from the earth’s surface moves into the air by EVAPORATION and becomes WATER VAPOR. Clouds are formed when rising air is cooled and the water.
Low Altitude Clouds Form below 2000 meters. Forms when warm, moist air rises, expands and cools. Made of water droplets only! There are 5 different.

C LOUDS. WHAT IS A CLOUD? A collection of water droplets Why White? -They are white, because they reflect the color of the sun. Why Gray? – They are gray.
Cloud Formation. Formation of Clouds Clouds are formed when water vapour is cooled below the dew point during its upward movement. Dew point – the temperature.
CLOUDS. * Form of condensation * Visible chunks of small water droplets or ice crystals * Good indicators of what’s going on in the atmosphere.
Clouds Amber and James. How are clouds formed? Clouds form by condensation. The sun heats the earth and the air above it. This warmer air will rise.
Why does it rain? (think back to work on the water cycle.)
CLOUD FORMATION There are 3 things required for clouds to form: 1.Water vapour 2.Change in temperature or pressure 3.Condensation nuclei (dust, smoke,
Clouds. What is a cloud? Warm air contains water vapor The air cools as it rises The water condenses around a solid object, such as dust or smoke, and.
