Flashcards in Atmosphere/Weather Review Deck (50):
What is the layer of gas that surrounds the earth?
What are the layers of the atmosphere?
Which layer contains gases essential for life?
Which layer does weather occur in?
In what layers does the temp decrease as the altitude increases?
Troposphere and Mesosphere
In what layers does the temp increase as the altitude increases?
Stratosphere and Thermosphere
Which layer includes the ozone?
Which layer do planes fly in?
Which layer is 50-80 km?
Which layer begins to merge with space?
Which layer has air that is highly ionized by UV rays?
What is special about the Ionosphere?
1. It keeps radio waves from completely leaving the atmosphere
2. It causes Auroras
What gases are found in the atmosphere?
Oxygen, Nitrogen, CO2 and Argon
Where are most of the gases found?
In the lower atmosphere
Which component of the atmosphere formed from the surface of the earth and pollution?
Which component is always present due to evaporation and is mostly near the surface?
Which component blocks UV rays in the higher atmosphere and is considered a pollutant in the lower atmosphere?
What are ionized particles sent out by the sun?
What are single oxygen molecules bounded with paired oxygen?
What does the Ozone do?
It blocks 99% of UV radiation
What is causing ozone thinning?
The release of CFC's
Where is the hole in the ozone?
What does dust form in the atmosphere?
Rain and fog
What is the transformation of water vapor to liquid when it comes in contact with a cooler object?
What is energy in the form of water?
What is the direct transfer of heat from a hot object to a cooler object?
What is the transfer of heat as warm air or liquid rises and cools air or liquid falls?
What is the only way heat can enter the earth?
What is the effect that traps heat radiation that radiated from the earth?
Why is the greenhouse effect necessary for life?
The earth would be frozen without it
What is the main cause of the modern greenhouse effect?
What are some other causes of the modern greenhouse effect?
Burning fossil fuel, deforestation, methane, and CFC
What is the relationship between temperature and altitude?
As altitude increases, temperature decreases
What is an upside down temp, condition where the ground radiates heat and cools faster than air?
How does temperature inversion form?
Cool air stays near the ground and traps smoke, fog, and other pollutants
What is smoke and fog mixed together?
How does the rotation and the tilt of the earth effect the temp of the earth?
1. The closer you are to the equator the more direct sunlight you are going to get, causing small differences between the warm seasons.
2. The middle part of the earth gets direct rays half of the year, causing extreme differences in the seasons
What is going on during the Winter Solstice?
The sun's rays are below the equator at the tropic of capricorn and are starting to go higher
What is going on during the Summer Solstice?
The sun's rays are above the equator at the tropic of cancer and are starting to go lower
What is going on during the Spring Equinox?
The sun's rays are at the equator and are rising
What is going on at the Autumnal Equinox?
The sun's rays are at the equator and are falling
What are the seasons of the earth like in the polar regions?
There are few direct rays, so it is cold most all of the year
What are the seasons of the earth like near the equator?
There is more direct sunlight, so there are only small differences between the warm seasons
What are the seasons of the earth like between the polar regions and equatorial regions?
There are direct rays for only half of the year, so there are extreme differences in the seasons
When are the warmest and coldest times of the day?
Warmest - Late afternoon
Coldest - Just before dawn
When is the warmest and coldest time of the year?
Warmest - July
Coldest - January
How is water heated and what affects the heating?
Heats up at different levels based on water clarity
How is land heated?
Only heats on surface, the top 1-2 feet
How does heat spread through water and land?
Much easier in water because of fluid and convection
