If you live far from the ocean, it is likely you will have a ______________ climate?
Where on Earth do the sun's rays hit least directly?
Earth's atmosphere traps energy from the sun. This allows water to exist as a ____________?
What does the tilt of Earth's axis as it revolves around the sun cause?
Where do the sun's rays hit most directly?
What best describes what scientists measure when they compare the readings of wet and dry bulb thermometers?
b. moisture in the air
c. wind speed
d. relative humidity
d. relative humidity
What do meterologists say are caused by uneven heating within short distances or small areas?
What are caused by uneven heating over long distances or larger areas?
What happens to solid molecules when they are heated?
a. move closer together
b. move further apart
c. they stay the same
move further apart (fast moving/less dense)
Molecules in cooler substances______________.
a. don't move
b. are moving faster
c. are moving slower
c. are moving slower (more dense/closer together)
Convection takes place because ______________ air is more dense than ______________ air.

b. water droplets
d. a gas
d. a gas
Which of the following are part of the water cycle?
Mild marine climates, like much of the west coast of the US, have _______winters and _______summers.
relatively warm winters and cool summers
What often happens when air moves from high pressure toward low pressure?
_________ are caused by differences in air pressure and temperature?
Air pressure decreases as you move away from the Earth. Further in the atmosphere, however,
air pressure first __________then____________.
increases, then decreases
Air in the atmosphere has pressure, because air has ____________?
Land cooling off faster than water causes ___________ breezes.
Winds are caused by differences in_________________.
Why does one hemisphere have summer at the same time the other hemisphere has winter?
- Due to the tilt of the Earth on its axis, one hemisphere receives direct rays/energy from the sun, causing warmer temperatures during the summer months. The opposite hemisphere receives least direct
- rays/energy from the sun at the same time, causing colder winter temperatures.
Why does lake effect snow occur?
Cold, dry air masses from the north travels over the great lakes. Land around the lakes cools down a lot faster than the water in the lakes. Warmer lake water is evaporated as the air mass travels over the warm water. The water vapor from the lake rises, cools, reaches its dew point, and condenses forming a lot of clouds. The clouds saturate and eventaully fall to Earth as a lot of precipitation/snow around the lake.
What are the names of the two snowiest cities in the US? Where are they located?
Rochester, NY and Buffalo, NY
