This is the amount of water in the air. What is humidity?

This is used to measure the amount of heat energy in an area. What is a thermometer?

This is used to measure the air pressure in an area. What is a barometer?

When wind speeds reach 74 mph, these storms occur over large bodies of water. What are hurricanes?

Turn to page 317. What is the first step in the formation of a tornado What is when air spins from the bottom of a thunderstorm?

This is what causes wind. What is the uneven heating of Earth’s surface?

These winds travel over a short distance and are caused by the uneven heating of land and sea. What are local winds?

Winds that travel over long distances and in only one direction. What are global winds?

Without wind, all of Earth’s precipitation would fall here. What is the ocean (right where it evaporated)?

Name the diagram. What is a sea breeze.

A large body of air that has the same temperature and humidity. What is an air mass?

This forms when two air masses collide. What is a front?

When these move through an area, they cause the weather to become humid and warm. What are warm fronts?

These cause cool, dry weather when they have passed through an area. What are cold fronts?

These cause warm air to be pushed up rapidly, often causing thunderstorms. What are cold fronts?

What are cumulus clouds? These clouds are in a “heap”. They look like cotton balls and indicate fair weather. What are cumulus clouds?

These clouds form high in the troposphere and are made up of ice crystals. What are cirrus clouds?

These clouds form low in the atmosphere These clouds form low in the atmosphere. They “spread out” and cover the sky. What are stratus?

These clouds are massive in size and produce heavy rains. What are cumulonimbus clouds?

On this weather map, where would clouds be least likely to form? 1 2 3 Region 1. High pressure systems usually have fair weather. In low pressure systems, warm air holding water vapor rises. Water vapor condenses on dust particles and forms clouds.

The main job of oceans. What is to keep Earth’s climate mild by removing heat (cooling) warm areas and distributing that heat to cold areas?

What is a convection current? When currents bring warm water to a cold area, it is evaporated and moved over land as part of this cycle. What is a convection current?

The main source of energy for ocean currents. What are global winds?

What is the fact that warm air is less dense than cold air? This is why warm air holds more water than cold air. It is also why warm air rises. What is the fact that warm air is less dense than cold air?

This is how oceans keep Earth’s climate mild. Ocean currents help to bring warm water from the equator to areas of the Earth that are closer to the poles and colder. When that warm water reaches land in those areas, it is evaporated and moved over land as water vapor by convection currents. There, it condenses to water and releases heated energy into the atmosphere, warming the climate of that cold area. This also keeps the tropical regions near the equator a little cooler.
