Unit 3 Weather Practice Test

Front

What is a high pressure area in weather?

Back

A high pressure area is a region where the atmospheric pressure is higher than that of the surrounding areas, typically associated with clear skies and calm weather.

Front

What is a low pressure area in weather?

Back

A low pressure area is a region where the atmospheric pressure is lower than that of the surrounding areas, often leading to cloudy skies and precipitation.

Front

How do high and low pressure areas affect weather?

Back

High pressure areas generally bring clear skies and stable weather, while low pressure areas are associated with clouds, rain, and storms.

Front

What causes a hurricane to form?

Back

A hurricane forms when warm, humid air rises over the ocean, creating a low pressure area. Cooler air spirals in, and the warm air continues to fuel the storm.

Front

What is a cold front?

Back

A cold front is the leading edge of a cooler mass of air that replaces a warmer mass of air, often resulting in precipitation and a drop in temperature.

Front

What weather conditions are expected when a cold front passes?

Back

When a cold front passes, it typically brings a drop in temperature, increased wind, and precipitation.

Front

What is the significance of temperature in predicting frozen water pipes?

Back

Frozen water pipes are likely when temperatures dip near or below the freezing point (32°F or 0°C).

Front

What does a weather map indicate about high pressure systems?

Back

A weather map shows high pressure systems as areas with clear skies and stable weather, often moving in a clockwise direction.

Front

What is the relationship between air pressure and wind speed in hurricanes?

Back

In hurricanes, lower air pressure at the center leads to stronger winds as air rushes in to fill the low pressure area.

Front

What is the role of humidity in weather systems?

Back

Humidity refers to the amount of moisture in the air, which can influence cloud formation, precipitation, and storm development.
