They record the magnitude of the earthquake.

Answer

They determine the speed of seismic waves.

Question 3

What is Plate Tectonics Theory?

Accepted Answer

It states that the lithosphere is divided into slabs called plates which float and gradually move.

Answer

It states that the plates are moving due to the energy from the mantle

Answer

It states that the lithosphere is composed of a crust and an upper mantle.

Answer

It explains the similarities of countries in terms of rock components.

Question 4

Which does not describe the lithosphere?

Accepted Answer

Lithosphere is made of molten rocks.

Answer

Lithosphere is divided into slabs called plates.

Answer

Plates of lithosphere are gradually moving.

Answer

The lithosphere is made of the crust and the upper mantle.

Question 5

What type of rock makes up most of the oceanic crust?

Accepted Answer

Basalt

Answer

Granite

Answer

Shale

Answer

Limestone

Question 6

Which BEST describes the divergent plate boundary?

Accepted Answer

The plates in the divergent boundary are moving away from each other

Answer

The old crust is deformed resulting to the formation of mountains.

Answer

The plates in divergent boundary move towards each other

Answer

The new crust is destroyed during diverging of plates because the magmais flowing out melting its materials

Question 7

What are colliding when plateaus and mountains ranges are formed?

Accepted Answer

Continent-continent plate boundary

Answer

Continent- ocean convergent plate boundary

Answer

Ocean-Ocean convergent plate boundary

Answer

Cannot be determined

Question 8

What causes the other plate to subduct beneath the other plate during convergence?

Accepted Answer

The material of the other plate is denser than the other

Answer

The overriding plate is heavier than the other plate.

Answer

The plates have the same components and the overriding is by chance.

Answer

The plate that sinks beneath the other moved first than the other.

Question 9

The following shows the difference between convergent plate boundary and divergent plate boundary EXCEPT

Accepted Answer

A divergent plate boundary usually occurs in the seafloor while a convergent boundary occurs only on the continental crust.

Answer

A divergent plate boundary forms rift valley while a convergent boundary forms trenches

Answer

Plates in a divergent plate boundary is drifted away while in a convergent plate boundary is moving towards each other

Answer

A divergent plate boundary produces new crust while a convergent boundary destroys old crust.

Question 10

How are the plate boundaries classified?

Accepted Answer

Through the movements of the plates.

Answer

Through the location of the plates on the world map

Answer

Through the type of continents involved in the movement of the plates

Answer

Through the movement of the asthenosphere beneath the lithosphere

Question 11

Accepted Answer

Faults

Answer

Answer

Answer

Question 13

Which two plates formed San Andreas Fault?

Accepted Answer

North American Plate and Pacific Plate

Answer

Pacific Plate and South American Plate

Answer

North American plate and Nazca Plate

Answer

South American Plate and Nazca Plate

Question 14

Which is formed when continental plate converges with another continental plate?

Accepted Answer

Mountain

Answer

fault

Answer

island arc

Answer

volcano

Question 15

Which is formed when oceanic plate converges with another oceanic plate?

Accepted Answer

island arc

Answer

fault

Answer

ridges

Answer

rift valley

Question 16

The diagram on the shows the movement of the mantle under the Earth’s crust, which process is represented by the diagram?

Accepted Answer

convection

Answer

rotation

Answer

conduction

Answer

radiation

Question 17

At which geologic feature does new oceanic crust form due to seafloor spreading

Accepted Answer

mid-ocean ridges

Answer

trench

Answer

mountain ranges

Answer

rift valley

Question 18

Movement of the oceanic crusts in the Atlantic Ocean floor produced themid-oceanic ridge. In which part of the mid-oceanic ridge would theyoungest crust be seen?

Accepted Answer

along the ridge itself

Answer

farthest from the ridge

Answer

along the trench

Answer

at the side of the ridge

Question 19

The process of ___________ continually adds new crust to the ocean floor along both sides of the mid-ocean ridge.

Accepted Answer

seafloor spreading

Answer

continental drift

Answer

plate tectonics

Answer

convection

Question 20

It is an event in which Earth’s magnetic field changes direction

Accepted Answer

magnetic reversal

Answer

field reversal

Answer

polarity reversal

Answer

polar reversal

Question 21

How does magnetic stripping on the seafloor provide evidence of seafloor spreading?

Accepted Answer

Rocks found in different areas from the oceanic ridge show different polarity at different times.

Answer

Rocks of the same age found on the seafloor with different magnetic polarity.

Answer

The magnetic polarity of the old and young rocks found in the ocean floor are the same.

Answer

Rocks found far from the ridge are younger compared to those found near it suggesting formation at different times.

Question 22

An evidence that supports Wegener’s theory of continental drift is that ____.

Accepted Answer

fossils of the same organism have been found on different continent

Answer

land bridges still exist that connect major continents

Answer

major rivers on different continents match

Answer

the same magnetic directions exist on different continents
