What happens to a climate as a location nears the poles?
It gets colder.
How is it possible that there would be snow on high mountains that are located near the equator where it is very warm?
Because the higher the elevation, the colder the temperature.
What heats up faster: land or water?
Land
Climates located near the equator usually have what type of climate?
Warm
What do we call a "mistake" made in the DNA copying of an individual's genes that results in trait variation?
Mutation
How many years of data are required to determine regional climate?
30 or more
Describe air molecules at high elevations (2 characteristics!)
Spread out, not very many and slow moving
Why does land heat up faster than water?
Land is darker and absorbs more energy from the sun than water.
Climates near the equator are warmer because...
They receive more direct sunlight.
What do we call the distance from crest to crest on a wave?
Wavelength
Out of the four factors we are studying, what is the most influential factor on the climate of a region?
LATITUDE
Describe air molecules at low elevations. (2 characteristics)
Closer together, a lot of them and fast moving.
How do we describe the climate of locations that are near the water?
Mild
Rio de Jeneiro, Brazil has a latitude of 22.9*S and Mykanos, Greece has a latitude of 37*N. Who would be colder and WHY?

"It's windy today" is an example of...
weather
When molecules move quickly at low elevations, what do they create?

Mt Everest has the highest elevation of any mountain; what mountain range is it a part of?
The Himalayas
Describe the difference in the molecules in land vs water
Land has molecules that are compact and not moving much. The molecules in water are more spaced out and moving around.
