Chapter 28 and 29 Flashcards
What is Troposhere?
A layer extending an average of 12 km above Earth’s surface.
What is Temperature inversion?
This occurs when air temperature increases with altitude and the air becomes stable.
What is the Green House Effect?
Is the natural process in which certain gases in the atmosphere warm a planet as they absorb and emit infrared radiation.
How are the atmospheric layers divided?
Based on differences in composition and temperature.;
What gas makes up the majority of the atmosphere?
Nitrogen
What gas makes 21 percent of the atmosphere?
Oxygen
What is the remaining one percent in the atmosphere?
Trace gases-majority is Argon
What is the ozone layer?
Protects us from the harmful radiation.
In the Troposphere does temperature decrease or increase with altitude?
decreases.
How many layers are there in Earth’s Atmosphere?
5 layers
What are the name of the atmospheric layers closest to earth’s surface to farthest to earth’s surface?
Troposphere, Stratosphere, Mesosphere, Thermosphere, and Exosphere.
What layer is the ozone layer found?
Stratosphere
In the mesosphere does the temperature decrease or increase with altitude?
decrease
Does the thermosphere and exosphere affect weather?
No
How much of solar radiation is absorbed by Earth’s surface?
50%
How much solar radiation is reflected back by land and sea surface?
5%
How much solar radiation is absorbed by particles in the atmosphere?
20%
How much of radiation is reflected back by clouds and other particles?
25%
What are the three basic cloud types?
Stratus,cumulus, cirrus
Describe Stratus clouds.
Layered sheetlike clouds
Describe Cumulus clouds
puffy
Describe Cirrus clouds
Wispy and are high altitude clouds.
What are the steps of the water cycle?
evaporation,condensation, transpiration, precipitation,runoff, and infiltration
Jet Stream
A narrow band of fast-moving, high-altitude aire.
Coriolis effect
The apparent deflection of an object due to Earth’s rotation.
Air mass
A large volume of air with uniform moisture and temperature throughout.
weather fronts
air masses that interact in zones
How many jet streams are there in the world?
Four
How many pressure systems are there?
Two
What is a low pressure system also known as?
L
Which direction does air flows for low pressure system?
Counterclockwise
What are some results from a low pressure system?
cloud formation and precipitation.
What is a high pressure system also known as?
H
What direction does a high pressure system rotate?
Clockwise
What are some results from High Pressure system?
Clear skies.
What are the four types of weather fronts?
Cold, Warm, Stationary, and Occuluded.
How does a cold front form?
Cold air forces warm air upward in a fast and chaotic manner.
How is a cold front represented on a weather forecast?
A blue triangle
How are warm fronts formed?
Warm air rises gently above cold air.
How are hot fronts represented in forecasts?
Red semicircles
How are stationary fronts created?
Cold and warm air masses meet and neither front advances
How are stationary fronts represented on forecasts
Red half circles on top and blue triangles on bottom and they rotate.
How are occluded fronts created?
A fast moving cold front overtakes a slow warm front.
How do occluded fronts represented on forecast?
Purple triangle and semicircles rotate
Maritime climate
A climate that is strongly affected by an ocean.
Continental climate
A climate that is not directly affected by an ocean.
Sea breeze
Blows from over the water toward land in the afternoon, when the land is warmer than the ocean.
What is weather?
Are the day to day outside conditions.
What are the five spheres of Earth’s System?
Atmosphere, Cryosphere, Lithosphere, Hydrosphere, Biosphere.
What is the atmosphere?
The air around us.
What is biosphere?
Everything organic?
What is the hydrosphere?
Everything that is liquid water.
What is cryosphere?
Everything that is frozen water like in snow ice and glaciers.
What is the lithosphere?
Earth’s outermost layer.
What is the primary factor that influences climate at a given location?
Latitiude.
Where is solar radiation most intense on earth’s surface?
Equator.
At what degree does the sun rays hit the tropical area?
90 degrees.
At what angle does the sun rays hit the temperate?
45 degrees.
At what angle does the sun rays hit the pole?
30 degrees
What other factors determine climate?
Precipitation, mountains, and bodies of water.
On the windward side what are the conditions?
Cool, and wet, and a lot of vegetation.
What are the conditions of the leeward side.
Dry, not a lot of vegetation and warm.
