when colder air moves toward a warmer air mass; the air pushes beneath the warm air

What areas have some of the world's most extreme climates?

Which side of a mountain experiences more rain and is cool?

In the middle latitudes, summers are hot and winters are cold. t/f?

What describes the weight of molecules in a large mass of air?

a boundary between two air masses

the atmospheric conditions, along with the short-term changes, of a certain place at a certain time

areas of low rainfall on the downwind slopes of mountains

Mountains are barriers to winds but they do not affect climate. t/f?

Vegetation is sparse only covering about _____ of the desert land.

a large area of air that has uniform temperature, humidity, and air pressure

Warm air masses have lower pressure, which means more weight. t/f?

Polar regions are warmer because they receive more solar energy. t/f?

Coastal areas get colder than inland areas. t/f?

Cool dense air sinks making it difficult for clouds to form. t/f?

Rain forests make up ____ of earth's land surface but hold half of terrestrial life.

Which side of a mountain is dry and receives less rain?

Mountains affect climate because of their high altitude and changes in air pressure. t/f?

Scientists who study and predict weather

How much solar energy can ice and snow reflect?

Air masses can change as they move over earth's surface. t/f?

In a low-pressure system, winds will blow counterclockwise and _______________

When an approaching front stalls for several days with warm air on one side and cold air on the other side

What area is a forest with a high annual rainfall, no freezing temperatures, and a lot of plant/animal life?

Cool air masses have high pressure. t/f?

Cloudy weather and precipitation are associated with low pressure systems. t/f?

Warm Air in a low pressure system ______.

Air masses cannot collide with one another. t/f?

Cool air in a high pressure system sinks. t/f?

Which of the following variables DOES NOT get factored in to determine weather?

when a fast moving cold from catches up with a slower warm front; brings precipitation

Large bodies of water heat slowly so areas near oceans have ______________ climate in the summer.

___________________ largely determines the climate of most regions.

the long term average weather conditions that occur in a particular region

Soil &rock of lands warmer to higher temperatures than oceans which makes temperatures on continents more extreme. t/f?

In a high-pressure system, winds will blow ______________ and diverge

warmer air moves toward cold air; the warm air rises and glides above the cold air mass

__________ are dry lands that cover many parts of earth.

when air molecules are cool, they are ______ together.
