Large Scale Patterns Flashcards
how does climate determine large scale patterns?
climate determines the distribution of different types of communities across earth.
what are the large scale climate patterns?
weather
climate
what is weather?
description of physical condition of atmosphere (moisture, temperature, wind, pressure).
what is climate?
long-term pattern of weather in a particular area.
what does the tilt of the earth and rotation around its axis affect?
It causes differential heating of our daily and annual cycles because it causes long-term patterns of rainfall and solar radiation that define patterns of global climate.
what does the earth’s rotation affect?
winds at high pressure cells @ earth’s surface to circulate to the north/south.
What is solar radiation?
electromagnetic energy.
what does a short wavelength cause?
higher energy
the hotter an object is…
the shorter wavelengths of energy emitted.
some energy that reaches earth reflects back into the atmosphere. Where does that energy go?
- some is reflected into the atmosphere by gases: carbon dioxide, water vapor, methane.
- some is absorbed by the earth’s surface.
why do tropical regions have greater heating than other places?
*equator= titled towards sun and gets direct sunlight and warmer than other latitudes.
*warm air holds more moisture than cold air, increasing water holding capacity of air around the tropics.
*solar radiation draws water from vegetation, but then air saturates and water condenses and falls.
what happened to air that expands from the equator and looses much of its moisture?
it sinks @ 30 degrees Celsius and increases water-holding capacity and soaks cup and available water.
what happens (-) or (+) 30 degrees Celsius?
turns into deserts.
what happens to cold air from poles and warm air at 30 altitude?
picks up moisture and clash over 30-60 degrees latitude creating wet environments as a result of air cooling and descending.
what influences climate from the ocean?
ocean currents.
