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