1
What do the energy resources uranium and coal have in common?
Both release energy through combustion
Both are formed from remains of dead organisms
Both are acquired by mining the lithosphere
Both generate radioactive wastes
2
Which of the following interactions between Earth and solar energy works to warm Earth?
absorption of solar energy by continental land masses
reflection of solar energy from polar snowcaps
use of solar energy in the process of photosynthesis
transformation of solar energy into auroras
3
What is the primary means through which the sun warms Earth?
fluctuation of subatomic particles
transfer of energy through conduction
fluctuation of gravitational fields
transfer of energy by electromagnetic radiation
4
Which resources have the most drawbacks for the environment during their acquisition?
oil and coal
coal and solar energy
geothermal energy and oil
solar energy and geothermal energy
5
Low and high tides occur 2x a day. Which factor affects the tides the greatest?
air pressure differences
gravitational pull from the sun
gravitational pull from the moon
seasonal temperature variations
6
An air mass coming from Canada toward North Carolina would most likely bring which conditions?
warm and humid
warm and dry
cool and dry
cool and humid
7
Which conclusion is supported by the diagram?
The Northern Hemisphere is experiencing daytime.
The equator has the greatest number of deserts.
The tilt of Earth is causing icebergs to melt.
The Southern Hemisphere is experiencing summer
8
Which of the following best explains why Earth is tectonically active?
Earth's surface sits on a moving, semisolid layer
Earth's surface are under great pressure from ocean water
Some areas of Earth's surface are thicker than others
The surface rotates more rapidly than other layers
9
Which statement describes an action directly caused by density differences in tectonic plates?
Continental plates are thicker and contain older material
When ocean & continental plate collide, ocean plate subducts
Magnetic particles in ocean plates change at times
Ocean plates move outward from the mid-ocean ridge
10
Without oceans, temps would vary from current temps. What helps maintain the temps of Earth?
high humidity near the ocean
depth of ocean
evaporation of ocean water
density of ocean water
11
A volcano found in the center of a tectonic plate tends to be a result of which phenomenon?
unusually excessive erosion that wears away bedrock
activity at a hot spot
strong earthquake
pressure in thick sediments that produces heat
12
Which characteristic of the asthenosphere helps explain the evidence of crustal-plate motion?
the ability to deflect solar winds
the semiliquid physical state
the ability to absorb heat energy
the magnetic properties
13
Atmospheric carbon is the most important threat to the health of the biosphere. How?
Carbon atoms bond with water vapor to create acid rain
Carbon compounds can cause genetic damage when used for fuel
CO2 in the atmosphere serves as a carrier for diseases
CO2 gas can effectively trap heat in the atmosphere
14
Which movement of tectonic plates caused the rift valley to form
Two tectonic plates collided with each other.
Two tectonic plates separated from each other.
One tectonic plate slid under another.
One tectonic plate slid past another.
15
Which statement best describes the greatest impact the ozone layer has had on the geosphere?
Ozone is necessary for the formation of sedimentary rocks
Ozone prevents surface rocks from being cracked by UV light
Ozone layer oxidizes iron-containing surface rocks
Ozone allow liquid water to form and start eroding rocks
16
Which layer of Earth is the source of lava that erupts from volcanoes?
outer core
lithospher
inner core
asthenosphere
17
How would season on Earth differ if Earth's axis was at a 90 degree angle?
Season on Earth would not be affected.
The seasons would be the same everywhere all year long.
It would always be summer at the equator.
There would be no seasons anywhere on Earth.
18
Why does February sometimes have 29 days instead of 28?
The Moon completes more than one full cycle in some months,
It takes Earth about 3651/4 days to revolve around the Sun.
The speed at chich Earth orbits the Sun varies.
it takes the Moon about 27 days to revolve around Earth.
19
Which most likely caused the changes observed in the data over time?
increase in the amount of precipitation
decrease in the amount of recharge
decrease in irrigation for farming
increase in water conservation efforts
20
How did the discovery of identical fossils on distant continents support Continental Drift?
it suggested liquid rock in the mantle hardens the crust
it suggested forces caused continents to separate over time
it showe that the cooling of Earth helped produce continents
it showed evolution is similar on separate continents
