What happens during atmospheric convection?
Cool air circles pockets of warm air.
Warm air circles pockets of cool air.
Warm air rises and cool air sinks.
Cool air rises and warm air sinks
Convection currents from uneven heating of the Earth's surface cause _______.
Fossils
Volcanoes
Mountains
Wind
Which statement correctly defines wind?
The movement of air from areas of low pressure to areas of high pressure
The movement of air to a colder area in the atmosphere.
The movement of air from areas of high pressure to areas of low pressure.
The movement of air pushed around and bouncing off Earth's surface.
Why do mountain climbers often wear masks at high altitudes?
The air is less dense, so there is less oxygen to breathe.
The air pressure is higher, making it harder to breathe.
The temperature is too high, requiring filtered air.
The air contains too much oxygen, which can be harmful.
What type of weather would a continental tropical air mass bring?
Dry and cold weather
Wet and cold weather
Dry and warm weather
Wet and warm weather
In the map above the label L indicates an area of low:
temperature

The weather map shows isobars very close together (a steep pressure gradient). Which of these is most likely occurring?
strong winds
low visibility
very low temperatures
very dry air
Air Pressure Gradient
a large body of air in the troposphere with similar characteristics of pressure, moisture, and temperature
the amount of difference in air pressure over a specific distance; the greater the pressure gradient, the greater the speed of wind
a weather instrument used to measure wind speed
the weight overlying atmosphere pushing down on a given unit of area
3. The Sun strikes the Earth the most at the Equator and the least at the poles. This causes warm air to ____________ from the equator and cold air to ___________ at the poles.

5. What is humidity?
Water, in liquid or solid form, that falls from the atmosphere.
The atmospheric conditions, along with short-term changes, of a certain place at a certain time.
The amount of water vapor in the air.
The force that a column of air applies on the air or a surface below it.
