Heat Transfer
Converting Units Temperature readings can be
converted from the Fahrenheit scale to the
Celsius scale using the following equation
3
What are three ways Heat is transferredgt

• Radiation
• Conduction
• Convection

Heat Transfer
Heat Transfer Heat transfer occurs when a warm
radiator heats a room. What type of heat transfer
could keep the paper in the air?
5

Global Patterns
Latitude and Temperature What are the three
temperature zones on the map?
10
Global Patterns
Distance from Large Bodies of Water Alaska 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.
Which climate data do you think describe Juneau?
Fairbanks?
11
Global Patterns
Currents and Temperature Warm ocean water warms
the air above it. A cold current brings cool air.
12
Global Patterns
Wind and Precipitation Mountains can form a
barrier to humid air. What happens to the humid
air when it encounters the mountains?
13
Global Patterns
Jet Streams Which arrow shows the polar jet
stream on the diagram? Which arrow shows the
subtropical jet stream?
14
Air Pressure
Air Column The weight of the column of air above
you puts pressure on you. How does pressure from
air molecules keep you from being crushed?
15
Air Pressure
Reading a Mercury Barometer What would a low air
pressure reading look like?
16
Air Pressure
Inside an Aneroid Barometer An 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?
17
Air Pressure
Effect of Altitude on Pressure and Density How
densely packed would the molecules be at the
different altitudes?
18
Winds
Wind Direction and Speed Based on the direction
of the wind vane, which direction would the kite
be flying?
19
Winds
Land Breeze Where would you draw arrows to show
how a land breeze develops?
