A

Which point shows the prevailing westerlies? 1 2 3 4

1

How is an occluded front different from a cold front? Warm air is pushed up during an occluded front, while cold air moves quickly during a cold front. Occluded fronts cause warm air to feel dry, while cold fronts cause ground temperatures to feel cooler. Warm air moves slowly during an occluded front, while cold air is cut off from the ground in a cold front. Occluded fronts cause rapid changes in weather conditions, while cold fronts cause widespread cloud formation.

A

Which type of clouds are shown? cirrocumulus cumulonimbus cumulus stratus

A

How do ice and water on the ground affect incoming solar radiation? They filter 22 percent of solar radiation that reaches the surface. They reflect 4 percent of solar radiation that reaches the surface. They absorb 100 percent of solar radiation that reaches the surface. They scatter 5 percent of solar radiation that reaches the surface.

B

How does latitude affect climate? Latitude controls the angle of tilt for Earth's axis. Latitude determines the duration of daylight hours. Latitude causes air temperatures to remain cool at higher elevations. Latitude causes ocean currents to move in a certain direction.

B

What climate condition occurs during El Niño? dry heat throughout North America warm water moving toward the coast of South America heavy rain moving toward the coast of South America flooding throughout North America

B

When does the Northern Hemisphere receive the fewest direct rays from the Sun? during the fall equinox during the winter solstice during the spring equinox during the summer solstice

B

Which characteristic describes the troposphere? contains the ozone layer has the highest air pressure spans 12-50 km above Earth is a good place for planes to fly

B

Which description refers to cirrus clouds? are fluffy are wispy produce snow form at low altitudes

B

Which is a type of heat transfer that causes the air at the top floor of a building to be hotter than the air at the bottom floor of a building? conduction convection radiation reflection

B

Which is one way that Earth's atmosphere supports life? It filters out oxygen. It keeps Earth warm. It increases UV radiation. It provides a solid shield.

B

Which phrase describes air density? increases as altitude increases equals mass divided by volume pushes molecules in one direction exerts less pressure as it increases

B

Which statement best describes a characteristic of maritime polar air masses? They occur mostly during the summer. They form over water with cool, moist air. They bring dense, heavy snow in the winter. They have cool, dry air that forms over land.

B

A person trapped outside during a thunderstorm should lie in a ditch or other low-lying area. get out of a car and take shelter under a tree. stay away from trees, water, and tall objects. run away from the thunderstorm as quickly as possible.

C

How can the process of climate change best be described? artificial and sporadic dangerous and quick natural and continuous unnatural and short-term

C

How do changes in wind currents affect the short-term climate in a region? Prevailing winds can cause a milder climate with heavy rain. Global winds can cause a longer summer. Prevailing winds can cause heavy rains or a dry climate. Global winds can cause a longer winter.

C

In addition to liquid precipitation, which are present when freezing rain occurs? ice pellets snowflakes cold surfaces warm temperatures

C

Joe, a hiker, stands at the top of a hill on a trail above the ocean. Joe's friend Dave is just starting out at the trailhead, which is at the beach. Which statement about this scenario is accurate? The air Joe is breathing is denser than the air at sea level. The air pressure is higher where Joe is than where Dave is. If Joe keeps going up, air pressure will continue to decrease. The air Joe is breathing is denser than the air Dave is breathing.

C

What percent of solar radiation is filtered by clouds and may cause sunburn on cloudy days? 3 percent 14 percent 22 percent 31 percent

C

What type of weather will this part of the United States most likely experience due to the incoming air mass? thick fog with cold air sunny skies with dry air humid conditions and rain cooler temperatures with no rain

C

Where does the energy within the greenhouse effect originate? from convection within the atmosphere from the circular movement of hot and cold air from solar radiation entering the atmosphere from the conduction of heat from the ground to the air

C

Which causes an increase in greenhouse gases? change in wind patterns strengthening of hurricanes burning of wood and coal movement of warm ocean waters

C

Which condition is necessary for water droplets to condense and form clouds? dry air ice crystals in air tiny particles in air rising temperatures

C

Which describes how prevailing winds affect precipitation in a region? Prevailing winds force cool, moist air from oceans to rise. Prevailing winds blow in the opposite direction as normal winds. Prevailing winds cause huge air masses, both warm and cool, to move. Prevailing winds that move over land usually cause the most precipitation.
