The diagram represents a model of Earth’s surface and internal structure. Letters A, B, C, and D represent four different layers. Some depths below Earth’s surface are shown. Which Earth layer is inferred to be composed of solid nickel and iron?

In which area of Earth’s interior is the pressure most likely to be 1.2 million atmospheres?

Asthenosphere

Stiffer Mantle

Inner Core

Outer Core

At which depth below Earth’s surface is the interface between Earth’s outer core and stiffer mantle located?

700 km

2900 km

2000 km

5100 km

Scientists have classified Earth’s interior into the known layers based primarily on evidence gained by studying

deep drill cores

volcanic eruptions

gravity measurements

earthquake seismic waves

According to the Earth Science Reference Tables, as the depth within the Earth's interior increases, the

density, temperature, and pressure increase

density, temperature, and pressure decrease

density and temperature increase, but pressure decreases

density increases, but temperature and pressure decrease

Compared to oceanic crust, continental crust is generally

older and thinner

older and thicker

younger and thinner

younger and thicker

According to the plate tectonics theory, the Peru-Chile Trench and the Andes Mountains formed along the west coast of South American because the South American Plate

collided with the Nazca Plate

collided with the North American Plate

slid away from the Nazca Plate

slid away from the North American Plate

When two tectonic plates collide, oceanic crust usually subducts beneath continental crust because oceanic crust is primarliy composed of igneous rock that has

low density and is mafic

low density and is felsic

high density and is mafic

high density and is felsic

The cross-section shows the direction of movement of an oceanic plate over a mantle hot spot, resulting in the formation of a chain of volcanoes labeled A, B, C, and D. The geologic age of volcano C is shown. What are the most likely geologic ages of volcanoes B and D?

B is 5 million years old and D is 12 million years old

B is 12 million years old and D is 6 million years old

B is 9 million years old and D is 9 million years old

B is 10 million years old and D is 4 million years old

10.

The movement of tectonic plates is inferred by many scientists to be driven by

tidal motions in the hydrosphere

density differences in the troposphere

convection currents in the asthenosphere

solidification in the lithosphere

11.

Which features are commonly formed at the plate boundaries where continental crust converges with oceanic crust?

large volcanic mountain ranges parallel to the coast at the center of the continents

A deep ocean trench and a continental volcanic mountain range near the coast

An underwater volcanic mountain range and rift valley on the ocean ridge near the coast

Long chains of mid-ocean volcanic islands perpendicular to the coast

12.

The map to the right shows the continents of Africa and South America, the ocean between them, and the ocean ridge and transform faults. Locations A and D are on the continents. Locations B and C are on the ocean floor. The oldest basaltic crust is most likely located at point

13.

A seismic station is located 8000 kilometers from the epicenter of an earthquake. How long did it take the first P-wave to travel from the epicenter to the seismic station?

9 minutes 20 seconds

11 minutes 20 seconds

20 minutes 40 seconds

4 minutes 20 seconds

14.

A seismograph records the arrival of a P-wave at 11:13 am. If the earthquake occurred 4000 kilometers from the recording station, when did the earthquake occur?

11:06 am

11:13 am

11:11 am

11:00 am

15.

Which statement correctly compares seismic P-waves with seismic S-waves?

P-waves travel faster than S-waves and pass through Earth’s liquid zones.

P-waves travel faster than S-waves and do not pass through Earth’s liquid zones.

P-waves travel slower than S-waves and pass through Earth’s liquid zones.

P-waves travel slower than S-waves and do not pass through Earth’s liquid zones.

16.

The P-wave generated by an earthquake took 2 minutes and 40 seconds to reach one of the seismic stations. Approximately how long did the S-wave take to reach the same seismic station?

1 minute 20 seconds

2 minutes 40 seconds

3 minutes 30 seconds

4 minutes 50 seconds

17.

How many seismic stations must report seismogram information in order to locate an epicenter?

One

Two

Three

Four

18.

The seismogram shows P-wave and S-wave arrival times at a seismic station following an earthquake. The distance from this seismic station to the epicenter of the earthquake is approximately

1,600 km

3,200 km

4,400 km

5,600 km

19.

Earth’s internal heat is the primary source of energy that

warms the lower troposphere

melts glacial ice at lower altitudes

moves the lithospheric plates

pollutes deep groundwater with radioactivty

20.

In which layer of Earth’s interior is the inferred temperature 6,000º C?

crust

outer core

inner core

mantle

21.

The composition of Earth’s core is thought to be the same as the composition of many

meteorites

volcanic ashes

granites

basalts

22.

On the map above, line AB is drawn across several of Earth’s tectonic plates in the South Atlantic Ocean. Which cross section best represents the plate boundaries and mantle movement beneath line AB?

23.

Which graph best shows the range of density in each of Earth’s layers?
