Answers

1
Which of the following best describes the mechanism for cloud formation?
Descending air cools causing condensation of clouds
Rising air heats by the Sun, forcing condensation of clouds
Rising air expands and cools forcing condensation of clouds.
Descending air is compressed and water vapor forms clouds

1
4
2
3
4

Volcano
Island Arc
Mid-Ocean Ridge
Mountain
5
Which of the following has the greatest affect on global climate?
solar energy
the ozone hole
earth's internal heat
automobile exhaust
6
What is the main cause of earthquakes and volcanoes on Earth's surface?
Pressure in the mantle being released quickly
Combined influence of the gravity from the Moon and Sun
Uneven heating and cooling of the surface of the Earth
The release of excess carbon into the atmosphere
7
Tides are caused by
The shifting of plates on the ocean floor
strong winds that blow over the ocean
gravitational interaction of Earth, the moon and the Sun.
Earth's revolution around the Sun.
8
Which best explains why the oceans have a great impact on the weather over the continents?
The oceans store and transfer more heat than the continents.
Ocean waves move more easily than continental rock.
Ocean water contains more salt than continental lake water.
Oceans have wider variety of organisms than continents.
9
Which of the following most likely causes pebbles in a stream to erode?
movement of ice
freezing and thawing
force of gravity
flowing water
10
What position must the Moon be located in for a solar eclipse to occur?
B
C
A
D
11
Which of the following would result in a decrease in average surface temperatures on Earth?
an increase in carbon dioxide in the atmosphere.
continental ice melting into ocean water
ash from a major volcanic eruption
an increase in decomposer populations
12
Which organisms would be the oldest in the diagram below?
early horses
armored fish
dinosaurs
trilobites
13
What would happen if the temperature of Earth's atmosphere was equal, ground to outer space?
Air movement would stay the same.
Air movement would stop.
Air movement would speed up.
Air movement would slow down.
14
Which of the following is the source of most of the atmosphere's oxygen?
polar ice caps and other parts of the cryosphere
consumers
volcanoes and other parts of the geosphere
producers
15
Which statement is BEST supported by the fossil record?
Most early life-forms that left fossils still exist today.
Fossils are found only in areas that were once under water
Most early life-forms that left fossils are now extinct.
Fossils are found in nearly all rock types.
16
Why do hurricanes form in ocean waters near the equator?
They need frictionless surfaces of large oceans to form.
They need the jet stream winds of the tropics to form.
They need the warm, humid air above tropical oceans to form.
High pressures of the tropics form the hurricane eye.

acid rain reacting with limestone bedrock
granite being crushed into clay-sized particles
water freezing in the cracks of a roadside outcrop
rocks falling off the face of a steep cliff
20

extrusive igneous rock
intrusive igneous rock
metamorphic rock
sedimentary rock
21
A glacier is a slow moving river of ice. How does a glacier help create soil?
It melts and becomes part of streams and rivers.
It carries plants down mountains and to oceans.
It freezes small particles of dirt to form large rocks.
It scrapes small particles off large rocks.
22
Which arrow shows heat transferred by convection as the Sun strikes sand on the beach?
3
2
1
4
23

the Moon absorbs light from Earth
the Moon transmits sunlight
the Moon reflects sunlight
25
Which method transfers heat from deep in Earth's interior to the crust?
