Test Description: Use to review for SES 3-6
Instructions: Answer all questions to get your test result.
1) The convergence of two continental plates would produce
A
an island
B
a valley
C
a trench
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 reflected off the moon and back into space
C
it loses energy overcoming the Sun's gravity
D
it is absorbed or reflected by the atmosphere
3) Permanent deforestation can contribute to global warming by
A
increasing CO2 levels
B
decreasing N2 levels
C
decreasing CO2 levels
D
increasing N2 levels
4) Which increases average global temperatures?
A
increased fossil fuel usage
B
increased biodiversity
C
decreased CO2 emissions
D
increased ocean algae
5) More solar energy reaches the equator than the poles because equatorial regions
A
receive sun rays closest to vertical
B
have more hours of daylight
C
are covered by more land
D
have more plants to absorb the light
6) What causes the wind deflection from the poles towards the equator?
A
rotation of Earth on its axis
B
the difference in land mass between the two hemispheres
C
the oblong shape of the Earth
D
Tilt of Earth's axis relative to its orbital plane
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
Greenhouse Effect
B
Coriolis Effect
C
Temperature Inversion
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
North
C
East
D
South
10) Where would a rain forest most likely be found?
A
20 degrees South of the Equator
B
near the equator
C
20 degrees North of the Equator
D
in California
11) Snow on the ground prevents the poles from heating up because...
A
snow absorbs greenhouse gases
B
heat is actually released from Earth's core
C
snow reflects solar radiation
D
heat spreads from the equator
12) Which cycle was made possible by photosynthetic cyanobacteria?
A
nitrogen
B
oxygen
C
phosphorus
D
water
13) Limestone has carbon in it. How is the carbon in the limestone most often released into the atmosphere?
A
chemical reaction between limestone and rainwater (chemical weathering)
B
formation of stalactites and stalagmites in limestone caves (deposition)
C
destruction of limestone by lichens (biological weathering)
D
abrasion by wind-blown sand (physical weathering)
14) What material is to blame for the holes in the ozone layer?
A
chlorofluorocarbons (CFCs)
B
fossil fuels
C
hydrocarbons
D
coal-containing sulfur
15) What type of energy from the oceans is responsible for weather patterns?
A
magnetic
B
mechanical
C
thermal
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
long growing season
B
high nutrients
C
small population changes
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 public awareness of global warming issues
B
reduce pollutants commonly associated with fossil fuel combustion
C
increase concentration of atmospheric ozone
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
geyser formation
B
volcanic eruption
C
earthquake activity
D
plate subduction
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
scientists cannot easily reach groundwater to determine flow rate
C
groundwater freezes easily so its more difficult to measure 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
Coriolis Effect
C
global winds
D
salt concentration
