Atmosphere
Name the 4 layers of the Atmosphere from bottom to top.
Troposphere, Stratosphere, Mesosphere, Thermosphere
What layer does weather occur in?
Troposphere
What are of the 5 steps of the water cycle.
Runoff, Evaporation, Condensation, Precipitation, Transpiration.
The four main types of fronts
Cold front, warm front, stationary front, occluded front
What are the four air mass types:
cP- Continental Polar
cT- Continental Tropical
mP- Maritime Polar
mT - Maritime Tropical
As you increase altitude in the atmosphere the pressure will________________
Decrease
What is the hottest layer?
Thermosphere
Water molecules heat up from the sun and turn into water vapor
Evaporation.
Forms when a cold air mass quickly pushes under a warm air mass and raises it up. Brings very strong storms and rainy weather.
Cold front
Cumulus, Stratus, Cirrus
What layer is the coldest?
Mesosphere
Meteors burn up in this layer:
Four types of precipitation.
Rain, snow, sleet, hail
Forms when a warm air mass slowly moves over a cold air mass. Brings warm drizzly weather.
Warm front
Cyclones rotate in what direction?
Counter-clockwise
The ozone layer protects us from what?
UV radiation
Water in a plant will evaporate from the leaves.
Transpiration
When a cold air mass and a warm air mass meet and both are equally strong so neither move. This causes rainy weather.
Stationary Front.
Anticyclone usually bring what kind of weather.
Brings clear, sunny weather
What are the percentages of the gasses that are found in the atmosphere:
Nitrogen:
Oxygen:
Other Gasses:
Nitrogen: 78%
Oxygen: 21%
Other Gases: 1%
Measure of force with which air molecules push on a surface.
Air pressure
This forms when water vapor in the air becomes liquid or ice crystals.
Clouds
Forms when a cold air mass and a cool air mass meet and push up a warm air mass off the ground.
Occluded front.
What kind of weather does a low pressure bring?
Cloudy, rainy weather
