air pressure | how much the air pushes on any surface |
front | the place where one air mass meets another air mass |
fog | small liquid water drops that lie close to the ground |
Cirrus clouds | feathery clouds that form high in the atmosphere and are made of ice crystals |
Cumulus clouds | fluffy and white with flat bottoms that form lower in the atmosphere than Cirrus clouds. |

Cumulonimbus clouds | storm clouds that are dark and heavy and usually mean a strong storm is approaching. |
Sun | warms the land and oceans. |
heat | is transferred to the atmosphere and warms the air |
moving air | wind |
ocean current | ocean water that flows from one place to another, affecting the weather and climate of an area. |
wind | can carry clouds and air masses with them to affect the weather and climate of an area |
rain | liquid drops of that fall from clouds |
drizzle | small raindrops |
snow | frozen water that is made of ice crystals called snowflakes |
sleet | small drops of ice that are formed when falling snow melts and then freezes again |
hail | pellets or chunks of ice |
atmosphere | a mixture of gases and air that surround the earth. |
hydrosphere | includes all the water found on Earth |
biosphere | includes all living things found on Earth |
geosphere | is made up of a thin surface layer of rock, soil, and sediments and well as the layers of the Earth. |
precipitation | water that falls to the Earth's surface in the form of rain, snow, sleet, or hail |
