weather

air pressure

• is the measure of the force with which air molecules push on a surface

• how much air someone can blow in a balloon

• it make clouds get bigger

• the pressure of rock

altitude

• How low something is relative to the Earth

• is the height of an object above the Earth's surface

• How high a mountain is

• How high the ground is compared to the height of air

Coriolis effect

• spinning of the Earth

• Pressure pushing down on Earth

• The movement of wind is affected by the rotation of the Earth.

• The wind changed by the amount of altitude

jet stream

• A stream of air causing jets to move slower

• Circle of wind that causes rain and snow

• High winds that blow across the earth

• are narrow belts of high speed winds that blow in upper troposphere and lower stratosphere

What causes wind

• unequal heating of the Earth's surface and by pressure differences

• Movement of trees

• spinning of the Earth and the tilt of the Earth

• Cloud build up blocking the sun's light

What is an air mass

• A mass of air blow the Earth's surface

• Is a large body of air that has similar temperature and moisture

• The height air is above the Earth's surface

• Is what causes air to move a cloud

Front

• When wind is in front of another movement

• kind of movement of streaming air

• when 2 different air masses meet, a boundary between them

• How movement of a air mass sinks to the surface of the Earth

local winds

• are influenced by the geography of an area

• winds that only blow at the Earth's surface

• raise of air because of altitude

• movement of an air mass
