Interactions Among Earth’s Spheres
The Earth System
Earth has five spheres.
Energy in Earth’s Atmosphere
Radiation From the Sun
Energy travels to Earth as electromagnetic waves. What are the types
of electromagnetic radiation in the diagram?
Energy in Earth’s Atmosphere
Energy in the Atmosphere
Some wavelengths reach Earth’s
surface. Other wavelengths are
completely or partially absorbed in
the atmosphere.
Energy in Earth’s Atmosphere
Use the higher percentages below to show a bar graph. Give it a title.
Energy in Earth’s Atmosphere
Energy at Earth’s
Surface
Complete each sentence
with a word from the
Word Bank to learn what
is happening to the
energy at Earth's surface
and in the lower
atmosphere.
Energy in Earth’s Atmosphere
Greenhouse Effect
The greenhouse effect is a
natural heat-trapping
process. What is the
sequence of events that
causes it to occur?
Energy in Earth’s Atmosphere
Heating of Earth’s Surface
The angle of the sun's rays causes temperature differences at Earth's surface.
Which areas on Earth receives the most direct light from the sun, and which
areas receive the least?
Energy in Earth’s Atmosphere
The Coriolis Effect
The Coriolis effect determines the direction of global winds.
Energy in Earth’s Atmosphere
Global Wind Belts
The Coriolis effect and other factors combine to produce a pattern of wind belts
and calm areas around Earth. Match the descriptions of the global winds with their
location on the globe.
Climate and Climate Regions
Reading Climate Graphs
A graph of temperature can be combined with a graph of precipitation
to form a climate graph. The graphs below show climate data for
Makindu, Kenya.
Climate and Climate Regions
Bangkok, Thailand
A tropical, rainy climate.
Climate and Climate Regions
Orlando, Florida
Nearly all of Florida lies within a temperate marine climate.
Climate and Climate Regions
Godthåb, Greenland
Polar climates are the coldest climates. In polar climates, short, cool
summers follow bitterly cold winters.
Climate and Climate Regions
Mexico City, Mexico
The climate on the lower slopes of a mountain range is like that of the
surrounding countryside. But in the highlands, or the higher slopes of
mountains, temperatures are lower and precipitation increases.
Climate and Climate Regions
Moving Continents
How has continental movement affected climate?
Climate and Climate Regions
Glaciers in North America
The map shows the parts of North
America that were covered by
glaciers 18,000 years ago.
Climate and Climate Regions
Ice Ages and Temperature
The estimated average worldwide temperature for the past 350,000
years was about 14°C. Cold glacial periods have alternated with
warm interglacial periods.
Natural Disasters in Florida
Ben wants to know the
average number of
hurricanes that struck the
east coast annually from
2003 through 2008. Which
measure of central
tendency should Ben use?
Natural Disasters in Florida
Hurricane Paths
The east coast of the United States, including Florida, is at high risk for
hurricanes.
Natural Disasters in Florida
Florida Disasters
Natural disasters have
greatly affected human life
in Florida. Can you point to
an area on the map that
was affected by a
disaster?
Natural Disasters in Florida
Warnings about
Possible Storms
What is the appropriate
storm related to each
sign?
Composition & Structure of the
Atmosphere
Gases in the Air
Which circle graph shows the correct percentage of gases in the
atmosphere? How should each portion of the graph be labeled? What
would be a good title for the graph?
Composition & Structure of the
Atmosphere
Troposphere and
Stratosphere
Earth's weather occurs in the
troposphere. The stratosphere
contains the ozone layer.
Composition & Structure of the
Atmosphere
Changing Temperatures
The graph shows how temperatures in the atmosphere change with
altitude.
Composition & Structure of the
Atmosphere
Mesosphere and Thermosphere
The mesosphere protects Earth’s
surface from being hit by most
meteoroids. In the thermosphere,
the air is thin and you cannot feel
heat.
Human Activities and Climate Change
Ozone Cycle
Ozone in the atmosphere is constantly being created and destroyed.
Human Activities and Climate Change
Ozone Hole
The ozone hole (shown in blue) is over Antarctica. The hole has grown over
time, but its size varies seasonally and from year to year. Mario José Molina
and two other scientists won the Nobel Prize for Chemistry in 1995 for their
theory that gases used in many household products help create the hole.
Human Activities and Climate Change
Greenhouse Effect
Which word in the Word Bank completes
each sentence?
Human Activities and Climate Change
Carbon Dioxide Levels
The graph shows the levels of carbon dioxide in the atmosphere over
time.
Human Activities and Climate Change
Sea Level Rise
The satellite image shows
how sea level rise could
affect the eastern United
States.
