Answers

1
What do the energy resources uranium and coal have in common?
Both release energy through combustion
Both are acquired by mining the lithosphere
Both generate radioactive wastes
Both are formed from remains of dead organisms
2
What is the primary means through which the sun warms Earth?
transfer of energy through conduction
fluctuation of subatomic particles
fluctuation of gravitational fields
transfer of energy by electromagnetic radiation
3
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,
4
Which layer of Earth is the source of lava that erupts from volcanoes?
lithospher
inner core
outer core
asthenosphere
5
Which statement describes an action directly caused by density differences in tectonic plates?
Ocean plates move outward from the mid-ocean ridge
Magnetic particles in ocean plates change at times
When ocean & continental plate collide, ocean plate subducts
Continental plates are thicker and contain older material
6
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
strong earthquake
pressure in thick sediments that produces heat
activity at a hot spot
7
Low and high tides occur 2x a day. Which factor affects the tides the greatest?
seasonal temperature variations
air pressure differences
gravitational pull from the sun
gravitational pull from the moon
8
Which resources have the most drawbacks for the environment during their acquisition?
geothermal energy and oil
oil and coal
coal and solar energy
solar energy and geothermal energy
9
How did the discovery of identical fossils on distant continents support Continental Drift?
it showed evolution is similar on separate continents
it showe that the cooling of Earth helped produce continents
it suggested liquid rock in the mantle hardens the crust
it suggested forces caused continents to separate over time
10
Which of the following interactions between Earth and solar energy works to warm Earth?
transformation of solar energy into auroras
absorption of solar energy by continental land masses
reflection of solar energy from polar snowcaps
use of solar energy in the process of photosynthesis
11
Which conclusion is supported by the diagram?
The equator has the greatest number of deserts.
The tilt of Earth is causing icebergs to melt.
The Northern Hemisphere is experiencing daytime.
The Southern Hemisphere is experiencing summer
12
Which most likely caused the changes observed in the data over time?
increase in the amount of precipitation
increase in water conservation efforts
decrease in irrigation for farming
decrease in the amount of recharge
13
Without oceans, temps would vary from current temps. What helps maintain the temps of Earth?
high humidity near the ocean
density of ocean water
evaporation of ocean water
depth of ocean
14
Which movement of tectonic plates caused the rift valley to form
One tectonic plate slid under another.
One tectonic plate slid past another.
Two tectonic plates collided with each other.
Two tectonic plates separated from each other.
15
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
16
Which characteristic of the asthenosphere helps explain the evidence of crustal-plate motion?
the ability to deflect solar winds
the ability to absorb heat energy
the semiliquid physical state
the magnetic properties
17
Which statement best describes the greatest impact the ozone layer has had on the geosphere?
Ozone prevents surface rocks from being cracked by UV light
Ozone is necessary for the formation of sedimentary rocks
Ozone layer oxidizes iron-containing surface rocks
Ozone allow liquid water to form and start eroding rocks
18
An air mass coming from Canada toward North Carolina would most likely bring which conditions?
warm and dry
warm and humid
cool and dry
cool and humid
19
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
20
How would season on Earth differ if Earth's axis was at a 90 degree angle?
There would be no seasons anywhere on Earth.
It would always be summer at the equator.
Season on Earth would not be affected.
The seasons would be the same everywhere all year long.
