- 1. Multiple Choice
Iceland is able to use the large amount of volcanoes to its advantage. The underground magma is used to heat and supply electricity for a large portion of the country. The use of this type of energy has great advantage over burning coal because
renewable resources are being used
all answer choices are correct
the cost is much less than coal
it does not create CO2 which may contribute to climate change
- 2. Multiple Choice
Which of the following statements is not true of temperature in Earth's layers?
The heat in the interior of the Earth is maintained by internal pressure and density
The lithosphere has a higher temperature than the asthenosphere
Radioactive substances inside the Earth release energy which creates heat
heat increases with depth from the Earth's surface
- 3. Multiple Choice
The intense heat from Earth's interior that warms the magma beneath the Earth's surface is called
geothermal energy
hydrogen energy
tidal power
solar energy
- 4. Multiple Choice
Waves travel at different speeds through the Earth's interior. What property distinguishes the Earth's crust, mantle, and core?
mass
pressure
composition
temperature
- 5. Multiple Choice
The pie chart illustrates the fuel sources for electricity in the country. Which of the following statements is true according to the pie chart?
Renewable resources are the main source for electricity in the country
Nuclear energy accounts for a large part of the non-renewable resources in the country
Fossil fuels are the main energy source for electricity in the country.
Non-renewable resources are used as often as renewable resources in the country
- 6. Multiple Choice
Which diagram best represents the type of plate movement that results in FOLDED mountains?
- 7. Multiple Choice
Like the layers of the ocean, the Earth's crust is divided into part based on physical properties. Which of the following statements best describes a layer of the Earth?
The asthenosphere has the greatest density
The mesosphere has the least density
The outer core has the least density
The inner core has the greatest density
- 8. Multiple Choice
In which of these ways can volcanoes help build up new land?
by adding water vapor to the atmosphere
by adding heat to Earth's surface
by adding gases to the atmosphere
by adding lava to Earth's surface
- 9. Multiple Choice
As you move northwest through the Hawaiian Islands, the age of the islands increases. The older islands are northwest of the new islands because they
age faster than those to the east
formed from old, recycled, silica-rich magma
were made of less lava than the southwestern islands
formed first and were moved away from the hot spot
- 10. Multiple Choice
Where on the ocean floor is new ocean crust being created?
the continental shelf
the continental slope
the deep ocean trenches
the mid-ocean ridges
- 11. Multiple Choice
Which occurrence is NOT caused by the motion of Earth's plates?
ocean tides
mountain formation
earthquakes
volcanoes
- 12. Multiple Choice
The movement of the two continents as shown in picture can best explained by
plate tectonics
coastal flooding
magnetic changes
volcanic eruptions
- 13. Multiple Choice
Most earthquakes and volcanoes occur in areas of the Pacific Ocean called the "Ring of Fire." Scientists agree that the reason for this is
That part of the Earth is hotter than all other parts of Earth.
A large number of people live in these areas.
The ocean weighs so much that it forces magma up.
plate boundaries are located in those areas
- 14. Multiple Choice
The image represents the type of plate movement found on the San Andreas fault line. What type of motion would you expect to find this region?
convergent motion
divergent motion
transform motion
sea floor spreading
- 15. Multiple Choice
Which of the following would be the least likely cause of volcanic eruption?
gas pressure within Earth's crust
new magma flowing into an already full magma chamber
tectonic plates sliding past each other
tectonic plates colliding
- 16. Multiple Choice
Look at the picture of the table. According to this information, the earthquake that produced this damage had a magnitude of about
3.0
5.0
2.5
6.5
- 17. Multiple Choice
Which of these statements does NOT support the theory of plate tectonics?
The continents appear to fit together like pieces of a puzzle
South American mountain ranges align with African mountain ranges
Similar fossils are found on different continents
Antarctica seems to have always been covered with glaciers
- 18. Multiple Choice
Earthquakes are most likely to occur where
the density cracks thin areas of Earth's crust
heat causes the mantle to expand
there are plate boundaries
bubbles of magma rise to the surface
