Heat Transfer

Converting UnitsTemperature readings can be converted from the Fahrenheit scale to the Celsius scale using the following equation:

Heat Transfer Heat transfer occurs when a warm radiator heats a room. What type of heat transfer could keep the paper in the air?

Heat Transfer

Water in the Atmosphere

The Driest Place on EarthThere are places in the Atacama Desert where a single drop of rain has never been measured.

Water in the Atmosphere

The Water CycleWhat are the processes in the water cycle?

Latitude and TemperatureWhat are the three temperature zones on the map?

Global Patterns

Distance from Large Bodies of WaterAlaska is about twice the size of Texas. Factors influencing temperature, such as distance from large bodies of water, affect this big state in different ways.

Global Patterns

Which climate data do you think describe Juneau? Fairbanks?

Currents and TemperatureWarm ocean water warms the air above it. A cold current brings cool air.

Global Patterns

Global Patterns

Wind and PrecipitationMountains can form a barrier to humid air. What happens to the humid air when it encounters the mountains?

Global Patterns

Jet StreamsWhich arrow shows the polar jet stream on the diagram? Which arrow shows the subtropical jet stream?

Air Pressure

Air ColumnThe weight of the column of air above you puts pressure on you. How does pressure from air molecules keep you from being crushed?

Air Pressure

Reading a Mercury BarometerWhat would a low air pressure reading look like?

Inside an Aneroid BarometerAn aneroid barometer has an airtight metal chamber, shown in red. Which diagram shows the aneroid barometer under high pressure and which shows it under low pressure?

Air Pressure

Effect of Altitude on Pressure and DensityHow densely packed would the molecules be at the different altitudes?

Air Pressure

Wind Direction and SpeedBased on the direction of the wind vane, which direction would the kite be flying?
