Instructions: Answer all questions to get your test result.
1) The convergence of two continental plates would produce
A
a trench
B
an island
C
a valley
D
mountains
2) Only 50% of solar energy reaches Earth's surface. What happened to the rest of it?
A
It loses energy traveling through space
B
it is absorbed or reflected by the atmosphere
C
it is reflected off the moon and back into space
D
it loses energy overcoming the Sun's gravity
3) Permanent deforestation can contribute to global warming by

decreasing CO2 levels
B
increasing N2 levels
C
increasing CO2 levels
D
decreasing N2 levels
4) Which increases average global temperatures?
A
increased ocean algae
B
increased biodiversity
C
decreased CO2 emissions
D
increased fossil fuel usage
5) More solar energy reaches the equator than the poles because equatorial regions
A
have more hours of daylight
B
are covered by more land
C
have more plants to absorb the light
D
receive sun rays closest to vertical
6) What causes the wind deflection from the poles towards the equator?
A
the oblong shape of the Earth
B
rotation of Earth on its axis
C
Tilt of Earth's axis relative to its orbital plane
D
the difference in land mass between the two hemispheres
7) Ocean surface currents are created by
A
salinity variations
B
differences in water density
C
differences in water temperature
D
friction with winds
8) When a cold air mass is found under a warm air mass, the result is
A
Temperature Inversion
B
Greenhouse Effect
C
Coriolis Effect
D
Upwelling
9) Earth rotates in an Easterly direction. Therefore, southward wind currents in the Northern Hemisphere appear to be deflected to the
A
West
B
South
C
East
D
North
10) Where would a rain forest most likely be found?
A
in California
B
20 degrees South of the Equator
C
20 degrees North of the Equator
D
near the equator
11) Snow on the ground prevents the poles from heating up because...
A
heat spreads from the equator
B
snow absorbs greenhouse gases
C
heat is actually released from Earth's core
D
snow reflects solar radiation
12) Which cycle was made possible by photosynthetic cyanobacteria?
A
phosphorus
B
water
C
nitrogen
D
oxygen
13) Limestone has carbon in it. How is the carbon in the limestone most often released into the atmosphere?
A
abrasion by wind-blown sand (physical weathering)
B
chemical reaction between limestone and rainwater (chemical weathering)
C
destruction of limestone by lichens (biological weathering)
D
formation of stalactites and stalagmites in limestone caves (deposition)
14) What material is to blame for the holes in the ozone layer?
A
chlorofluorocarbons (CFCs)
B
fossil fuels
C
coal-containing sulfur
D
hydrocarbons
15) What type of energy from the oceans is responsible for weather patterns?
A
magnetic
B
thermal
C
mechanical
D
electrical
16) Arctic tundra has an average temperature of -11 Celsius, and average precipitation of 20cm/year. Based on this, what conclusion can be made about the tundra?
A
small population changes
B
long growing season
C
high nutrients
D
low biodiversity
17) Methane gathered from coal mines have been used to power fuel cells. Since the fuel in these cells is not burned, using methane will help to...
A
increase concentration of atmospheric ozone
B
reduce pollutants commonly associated with fossil fuel combustion
C
increase public awareness of global warming issues
D
reduce public demand for alternative fuel sources
18) What is most likely created when groundwater heated by the rock overlying a magma chamber is released back to Earth's surface through fractured rock?
A
volcanic eruption
B
earthquake activity
C
plate subduction
D
geyser formation
19) Why do scientists use a formula to estimate groundwater flow, instead of taking direct measurements as they do in surface freshwater streams?
A
there is more surface water than groundwater so it is easier to measure
B
groundwater freezes easily so its more difficult to measure flow rate
C
scientists cannot easily reach groundwater to determine flow rate
D
groundwater does not move underground so it has no flow rate
20) What is the driving force for surface ocean currents?
A
density layering
B
salt concentration
C
global winds
D
Coriolis Effect
