Answer

Oceanic ridge

Answer

Island

Answer

Canyon

Question 10

What is the term for a landform that forms when two plates collide and one plate is forced below the other?

Accepted Answer

a subduction zone

Answer

a mid-ocean ridge

Answer

a rift valley

Answer

a transform fault

Question 11

What is most likely to happen if oceanic crust and continental crusts converge?

Accepted Answer

A volcano formed on the surface of the continental crust due to the melting of subducted part of the oceanic crust.

Answer

Nothing will happen to both oceanic and continental crusts because the layers will melt in the asthenosphere.

Answer

Both continental and oceanic crusts will away from each other. This is called convergent boundary.

Answer

The denser continental crust is subducted beneath the less dense oceanic crust.

Question 12

Divergent boundaries could also exist between continental plates. If there are two crustal plates involved along with this boundary, what is the correct order of sequences and what processes will take place in 20 years based on the illustrations below?

Accepted Answer

1, 3, 4, 2; as magma rises from deep within the Earth and forms a new crust on the lithosphere.

Answer

1, 3, 4, 2; only where earthquakes occur. A submarine mountain range was formed too.

Answer

1, 2, 3, 4; where an underwater volcano develops.

Answer

1, 2, 3, 4; All geologic features/events happen.

Question 13

Geological features are results of internal processes of the Earth such as plate tectonics. Which is an example of landforms associated with the divergence of two continental plates?

Accepted Answer

The East African Rift Valley (EAR) is a developing divergent plate boundary in East Africa. where the eastern portion of Africa, the Somalian plate, is pulling away from the rest of the continent, that comprises the Nubian plate.

Answer

All of the above are applicable.

Answer

The Mid-Atlantic Ridge includes a deep rift valley that runs along the axis of the ridge for nearly its entire length.

Answer

The East Pacific Rise where Magma from deep in the Earth's mantle wells up in the gaps and forms new crust, eventually moving upwards and creating underwater ridges.

Question 14

Why does the oceanic crust subduct beneath the continental crust when two tectonic plates collide?

Accepted Answer

It is denser than the continental crust

Answer

It is less dense than the continental crust

Answer

It is thicker than the continental crust

Answer

It is thinner than the continental crust

Question 15

To find the epicenter of an earthquake, at least ______ seismic stations are needed.

Accepted Answer

3

Answer

2

Answer

1

Answer

4

Question 16

Love and Rayleigh waves can pass through ___________________.

Accepted Answer

the surface only.

Answer

all layers of the earth.

Answer

the mantle only.

Answer

the earthquakes only.

Question 17

How do scientists determine the epicenter of an earthquake?

Accepted Answer

They used the time interval of P and S waves in three different seismic stations to determine the epicenter.

Answer

They determine the arrival of seismic waves in a specific location.

Answer

They measure the time interval between primary waves, the fastest wave, and secondary waves.

Answer

The scientists used the different speeds of the P wave and S wave.

Question 18

Why is the P wave faster to reach the seismic station than the S wave?

Accepted Answer

P waves can move through solid rock and fluids, like water or the liquid layers of the Earth, allowing them to pass through easily.

Answer

The nature of its propagation and travel is longitudinal.

Answer

It can be transmitted only in solid rocks.

Answer

P waves can move through only the liquid layers of the Earth, allowing them to pass through easily.

Answer

South American plate

Answer

Eurasian plate

Question 20

Answer

Mid-Atlantic ridge

Answer
