Weather Final Review Test 14

Which most likely produces clear, cool weather?

• zero air pressure

• stable air pressure

• a low pressure system

• a high pressure system

Which best explains why a nearby body of water tends to make local temperatures milder?

• Water constantly releases heat into the air.

• Water gains and loses heat more slowly than land.

• Some water stays liquid when everything else is frozen.

• When water is frozen it protects the nearby area from wind.

Why is there usually more cloud cover at higher altitudes?

• Air pressure decreases at lower altitudes.

• Air pressure increases at higher altitudes.

• Water vapor condenses at cooler air temperatures.

• Water vapor condenses at warmer air temperatures.

Which has the greatest effect on the temperature of a region?

• the amount of plants it has

• the amount of rainfall it gets

• the amount of humans it has

• the amount of sunlight it gets

How would weather conditions in an area change if a high pressure system replaced a low pressure system?

• The area would become more stormy and rainy.

• The area would become more humid and warmer.

• The area would become cooler with less humidity.

• The area would become warmer with strong winds.

What form of precipitation, in which ice crystals freeze over and over, frequently occurs during thunderstorms?

• hail

• snow

• sleet

• heavy rain

Which type of air pressure causes a storm to form on a spring day?

• low pressure, causing air to rise, cool, and form water droplets

• high pressure, causing air to rise, cool, and form water droplets

• low pressure, causing air to sink and bring water droplets to the ground

• high pressure, causing air to sink and bring water droplets to the ground

If a weather system is moving from the Pacific coast to North Carolina, from which direction will the winds in North Carolina most likely blow?

• north

• west

• east

• south

Which best describes how changes in air pressure can affect the development of a hurricane?

• Cooling ocean water causes air pressure to drop. This causes high winds and rain to develop, which may become a hurricane.

• Cooling ocean water causes air pressure to rise. This causes light winds and snow to develop, which may become a hurricane.

• Warming ocean water causes air pressure to rise. This causes light winds and sleet to develop, which may become a hurricane.

• Warming ocean water causes air pressure to drop. This causes high winds and thunderstorms to develop, which may become a hurricane.

A strong low-pressure weather system forms off the coast and moves toward a land area. Which weather conditions will likely result from the low-pressure system?

• clear, sunny skies and calm winds

• mostly sunny skies with little to no precipitation

• partly cloudy skies with little precipitation and light winds

• mostly cloudy skies with moderate to heavy precipitation and strong winds
