Term
Characteristics of Atmosphere
Definition
6 main layers, protects us from harmful objects/ rays
Term
Homosphere
Definition
Similar throughout
Term
Heterosphere
Definition
Different throughout
Term
Troposphere
Definition
closest to Earth; we live in it; 7.5 mi, all weather occurs here
Term
Stratosphere
Definition
still, leaves white trail
Term
Mesosphere
Definition
coldest; meteoroids burn up here
Term
Thermosphere
Definition
hot
Term
Ionosphere
Definition
Thin air, lower region of thermosphere
Term
Exosphere
Definition
hottest layer, upper region of thermosphere
Term
What would mt. climbers have to do to prepare for an overnight stay?
Definition
Face their tent flaps toward the valley because heat rises during the night from the valley that has been collecting it all day.
Term
How God uses oxygen to sustain his creation
Definition
Animals, bacteria, microorganisms, and plants need it for respiraton
Term
How He uses Nitrogen
Definition
Plants use it to create proteins all animals need.
Term
Uses Carbon Dioxide
Definition
plants could not photosynthesize without it which would mean no oxygen from them
Term
If UV radiation is increased...
Definition
It causes cataracts, sunburn: skin cancer later in life, plankton die, and animals who eat them will die.
Term
Water Cycle
Definition
Water enters atmosphere through transpiration and the water vapor condenses into clouds. Then the water enters again through precipitation
Term
The ozone layer is important...
Definition
Because it protects us from UV radiation
Term
Troposphere means...
Definition
change
Term
Arctic regions are...
Definition
cold, icy, have long winters, short summers
Term
Temperate regions have...
Definition
4 seasons, 30d- 60d N or S
Term
Tropical regions...
Definition
have long summers and short winters, 0d-30- N or S
Term
Humidity
Definition
Amount of water vapor in the air when you feel hot or sticky
Term
Cold air masses
Definition
Form on poles, colder than earth's surface
Term
Warm air masses
Definition
form over tropical areas
Term
Cloud seeding and how it works
Definition
Clouds are seeded with crystals of dry ice which attrct water molecules which grow large enough to form rain or snow
Term
First stage of thunderstorm
Definition
Cumulus stage: warm air rises from the ground that is warmer than its surroundings; the air forms a cumulus clound and air currents flatten the cloud into a thunderhead
Term
Second stage
Definition
Mature stage: cumulus cloud grows and spreads out into an anvil shape, forming a cumulonimbus cloud, then the falling rain cools the air
Term
Third Stage
Definition
Final stage: Thunderstorm dies out as it uses up its supply of water vapor.
Term
Cold Fronts
Definition
Form when a cold air mass overtakes a warm one. The dense cold air lifts the warm air.
Term
Rainstorms
Definition
Appear along cold fronts When warm air is moistm cumulus and cumulonimbus clouds form. These produce violent, but short lived storms.
Term
High Pressure Area
Definition
Area where cold air is sinking
Term
Low Pressuse area
Definition
Where warm air is rising
Term
Thunder
Definition
Sound that results from rapid expansion of air that accompanies a lightening strike.
Term
Lightning
Definition
Eliectric discharge of energy from storm clouds
Term
Latitudes affect on daylight
Definition
It depends on the tilt of the sun and where the sun lies
Term
Inland temperature
Definition
warmer than coast, less rain
Term
Coastal Temperature
Definition
colder, more rain
Term
Major Greenhouse Gases
Definition
Water Vapor, carbon Dioxide, and Ozone
Term
CLimate
Definition
temperature over a long period of time
Term
Weather
Definition
day-to-day temperature changes
Term
Rainforests
Definition
charcterized by high rainfall, 40-75% of worlds species live here
Term
Winward side of mt.
Definition
Colder side of mt, and gets more rain
Term
Leeward
Definition
Not exposed to wind and weather/ side facing the wind
