Science Layers of the Atmosphere

Barometer

measures air pressure

Psychrometer

measures relative humidity

Anemometer

measures wind speed

isobar

A line on a weather map that joins places that have the same air pressure

What determines the boundaries between atmosphere layers?

Changes in air pressure and temperature

Artificial satellites orbit the earth here.

Exosphere/Thermosphere

In which layer would you see a meteor burn up?

Mesosphere

The ozone is found in the...

Stratosphere

weather

The condition of Earth's atmosphere at a particular time and place.

Which layer of the atmosphere has the lowest density of gas molecules?

Thermosphere/Exosphere

In which layer does the earth's weather occur?

Troposphere

Which layer contains the most density of air molecules?

Troposphere

What are the layers of the atmosphere bottom to top?

Troposphere; Stratosphere; Mesosphere; Thermosphere, Exosphere

Warm front

a front where warm air slides over cold air and brings drizzly rain and then are followed by warm weather

jet stream

a high-speed high-altitude airstream blowing from west to east near the top of the troposphere

If you climb a mountain, then air pressure

decreases

maritime tropical air mass

forms over the Gulf of Mexico; warm & humid

maritime polar air mass

forms over water near the poles; cold & humid

Cold front

forms when cold air moves under warm air which is less dense and pushes air up (produces thunderstorms heavy rain or snow

Stationary front

when a warm air mass and a cold air mass meet and no movement occurs
