|
How does the water move on the earth’s surface?
|
1. air currents (wind)
2. Earth’s rotation 3. Location of continents |
|
|
How does the water move deep in the ocean?
|
Changes in
density/salinity and temperature affect ocean water density |
|
|
The curved path of ocean currents and wind due to earth’s rotation:
|
Coriolis Effect
|
|
|
When cold, nutrient rich water comes to the surface because of wind:
|
upwelling
|
|
|
How does living near a large body of water affect the climate?
|
Temps are moderate because water does not absorb or release heat quickly
|
|
|
3 factors needed for hurricanes to form:
|
1. warm moist air (warm sst)
2. Coriolis effect 3. low wind shear |
|
|
The type of heat energy released by hurricanes:
|
Latent heat
|
|
|
This is given off when there is a phase change (evaporation and condensation):
|
Latent heat
|
|
|
The 2 seasons when hurricanes tend to form and WHY:
|
late summer & early fall
WHY: higher sst’s |
|
|
Hurricanes become weaker when they move from water to land because:
|
They lose their
warm water |
|
|
Warm water in the equatorial pacific moving east because of a change in wind explains this part of
El Nino: |
Why weather patterns change during El Nino
|
|
|
3 forms of severe weather that lead to flooding:
|
Blizzards
Hurricanes Thunderstorms |
|
|
A tornado takes this type of path when it touches down on land:
|
unpredictable path
|
|
|
Conditions needed for hail stones to form:
|
strong updrafts in a cumulonimbus cloud
|
|
|
How do cold air masses move?
|
pushed underneath warm air masses
|
|
|
The weather caused by cumulonimbus clouds:
|
thunderstorms
|
|
|
The season associated with most severe weather in the USA and WHY:
|
Spring
*air masses have the greatest difference in temperature |
|
|
This happens to an air mass when it hits a mountain range:
|
adiabatic cooling
|
|
|
An air mass rises and cools, this forms clouds:
|
adiabatic cooling
|
|
|
This type of landform forms on the side of a mountain that is not facing the wind and does not receive rainfall:
|
Rain shadow desert forms on the leeward side of the mountain
|
|
|
The main source of energy in the Earth’s climate system:
|
Sun
|
|
|
Ways to reduce the amount of carbon dioxide (CO2) in the atmosphere:
|
Use cars less
Turn down furnace Use less AC |
|
|
Warming of the atmosphere when greenhouse gases trap the sun’s heat:
|
greenhouse effect
|
|
|
Possible causes of Earth’s climate changing:
|
Human activity
Volcanic activity Orbital change Plate tectonics |
|
|
Things that may decrease temperatures by reflecting sunlight back into space:
|
Clouds, ice, snow, volcanic clouds
|
|
|
This is how scientists have shown that ice ages usually occur after carbon dioxide levels on the earth are low:
|
ice core samples
|
|
|
The one idea that scientists agree on regarding global warming:
|
CO2 has been
increasing |
