How much of the globe is covered by dry land rather than (liquid or solid) water?
a) 30%
b) 50%
c) 75%
d) 15%
Explanation:
About 75% of Earth is covered by ocean and 10% of the land surface is topped by ice. Exposed dry land is relatively scarce.

Which of the following is NOT one of the tectonic stresses experienced by Earth's crust?
a) Compression.
b) Tension.
c) Erosion.
d) Shear.
Explanation:
Erosion is a process that shapes Earth by acting at the planet's surface; erosion is NOT a result of plate tectonics. By contrast, the movement of tectonic plates DOES produce compressional, tensional, and shear stress.

When rock deforms elastically,
a) it is permanently deformed after stress is removed.
b) it returns to its original size and shape after stress is removed.
c) it stretches irreversibly, even after stress is removed.
d) it fractures along planes of weakness when stress is applied.

a) it is permanently deformed after stress is removed.
b) it returns to its original size and shape after stress is removed.
c) it stretches irreversibly, even after stress is removed.
d) it fractures along planes of weakness when stress is applied.
Explanation:
Elastic means behavior like a rubber band—it returns to original size and shape after stressed and released.

b) it returns to its original size and shape after stress is removed.
c) it stretches irreversibly, even after stress is removed.
d) it fractures along planes of weakness when stress is applied.
Explanation:
Plastic means behavior like chewing gum—it stays deformed when stressed and released.

When rock is stressed beyond its elastic limit,
a) minerals undergo retrograde metamorphism.

When rock is stressed beyond its elastic limit,
a) minerals undergo retrograde metamorphism.
b) the rock loses heat.
c) a new elastic limit is established.
d) it deforms plastically or breaks.
Explanation:
Folds and faults form when the elastic limit is surpassed. Cold rock is more brittle than warm rock, so warm rock deforms plastically to produce folds, and cold rock breaks to produce faults. Confining pressure also plays a role in determining elastic and plastic limits.

Rock in the center (or core) of a syncline is
a) younger than rock horizontally away from the center.
b) the same age as rock horizontally away from the center.
c) older than rock horizontally away from the center.

Rock in the center (or core) of a syncline is
a) younger than rock horizontally away from the center.
b) the same age as rock horizontally away from the center.
c) older than rock horizontally away from the center.
d) younger or older than rock horizontally away from the center.
Explanation:
Think of a syncline as being shaped like a bowl. Sedimentary rocks are deposited horizontally with newer, younger rock on top of older rock. Flatten out the bowl by squishing and spreading it out. If the bowl was layered rock, can you see that younger rock forms the outside or "upper" part (deposited last)?

Rock in the center (or core) of an anticline is
a) younger than rock horizontally away from the center.
b) the same age as rock horizontally away from the center.

a) younger than rock horizontally away from the center.
b) the same age as rock horizontally away from the center.
c) older than rock horizontally away from the center.
d) younger or older than rock horizontally away from the center.
Explanation:
Think of an anticline as shaped like an "A" or an upside-down bowl. Sedimentary rocks are deposited horizontally with newer, younger rock on top of older rock. Flatten out the "A" by squishing and spreading it out. If the "A" was layered rock, can you see that younger rock forms the outside or "upper" part (deposited last)?

c) up.
d) down.

For a normal fault, the hanging wall moves
a) sideways.
b) obliquely.
c) up.
d) down.
Explanation:
A block of rock of a certain size will be lengthened horizontally if a fault forms and the hanging wall moves down. Normal faults are the result of tension.

For a reverse fault, the hanging wall moves
a) sideways.
b) obliquely.
c) up.
d) down.
Explanation:
A block of rock of a certain size will be shortened horizontally if a fault forms and the hanging wall moves up. Reverse faults are the result of compression.

a) fluid basaltic lava.
b) alternating layers of lava, ash, and mud.
c) ash, cinders, glass, and lava fragments.
d) massive amounts of ash.
Explanation:
A composite cone is so named because it consists of layers of differing consistency.

Plains and plateaus are both flat landforms. How do they differ from one another?
a) Elevation
b) Geologic history
c) Elevation and geologic history
d) Geographical location
Explanation:
Plains are located at the bases of the mountain ranges that produce the sediment that composes them. Plateaus are pieces of crust that have been tectonically uplifted.

Where is most of Earth's fresh water found?
a) Lakes.
b) Ice caps and glaciers.
c) Rivers.
d) Underground.
Explanation:
79% of Earth's fresh water is currently locked up in ice! Less than 21% has the potential for use by land-based life.

What is the source of the energy that drives the hydrologic cycle?
a) The Sun, through the process of condensation.
b) The Sun, through the process of precipitation.
c) The Sun, through the process of warming.
d) The Sun, through the process of evaporation.

What is the source of the energy that drives the hydrologic cycle?
a) The Sun, through the process of condensation.
b) The Sun, through the process of precipitation.
c) The Sun, through the process of warming.
d) The Sun, through the process of evaporation.
Explanation:
To drive the water cycle, billions of tons of water must of lifted into the sky. This involves breaking the hydrogen bonds between liquid water molecules as well as lifting them up. All this takes energy! The Sun supplies it. The energy pumped into the evaporated water is spent by the water when it falls back to Earth, as it moves across and reworks the land.

d) the wedge of sediment at the base of the continental slope.
Explanation:
The continental rise is created by submarine "landslides" called turbidity currents.

Precipitation that does not infiltrate becomes
a) groundwater.
b) the water table.
c) soil moisture.

Explanation:
If water does not infiltrate, it stays on the surface and flows downslope.

The maximum amount of water a particular soil can hold is determined by the
a) porosity.
b) permeability.
c) degree of saturation.
d) amount of recharge.
Explanation:
Porosity is the percentage of open space in a soil. Water can only occupy open spaces—the higher the porosity, the larger the amount of water that can be held.

b) permeability.
c) degree of saturation.
d) amount of recharge.

An example of nonpoint water pollution is
a) heat from a nuclear power plant.
b) arsenic from a mine.
c) plastic bags in the ocean.
d) dead fish downstream from a factory.
Explanation:
Plastic bags come from a multitude of sources. Pollution from distributed, hard-to-pinpoint sources is non-point pollution.
