Chapter 1 Inside Earth

1.

1 point

Why isn't' the inner core molten?

It is too hot

That type of rock doesn't melt

Too much pressure for the rock to expand and become liquid

Not enough heat

2.

1 point

The lithosphere is broken into separate sections called

Continents

Plates

Faults

Boundaries

3.

1 point

Which layer is directly above the lithosphere

Crust

Asthenosphere

Mantle

Core

4.

1 point

Who had the theory of Continental Drift?

Hess

Wegener

Wilson

5.

1 point

A transform boundary is where

two plates move toward each other

two plates move up

two plates slide past each other

two plates moves apart from each other

6.

1 point

A divergent boundary is where

two plates move toward each other

two plates move up

two plates slide past each other

two plates moves apart from each other

7.

1 point

According to Wegener, how would the surface of Earth changed over the last 200 million years?

Earth is exactly the same as it was then

Pangaea broke up and continents moved to current locations

The mid-ocean ridge and sea floor spreading moved the continents

8.

1 point

Hess used which three pieces of evidence?

Fossils

Magnetic stripes

Molten material (pillow shaped rocks)

Drilling samples

9.

1 point

Where would you expect to find the oldest rock on the ocean floor?

at the mid-ocean ridge

a divergent boundary

farthest from the mid-ocean ridge

at the molten eruption site

10.

1 point

How does temperature and pressure change as you go down into the earth?

Both decrease

Both increase

Pressure increases but it get colder

Pressure decreases and temperature stays about the same.

11.

1 point

The mid-ocean ridge is a result of which type of boundary

transform

convergent

tension

divergent

12.

1 point

Which layer is the hottest?

Asthenosphere

Lithosphere

Inner core

Crust

13.

1 point

What causes convection currents in the mantle?

the sun

molten eruptions

heat from the core

pressure from the crust

14.

1 point

Which layer is directly below the mantle?

Outer core

Asthenosphere

Lithosphere

Crust

15.

1 point

Which layer is associated with granite?

Inner core

Continental crust

Lithosphere

Oceanic crust

16.

1 point

When two plates collide, which one will float on the other?

the most dense

the least dense

the oldest

granite

17.

1 point

What are the two types of evidence scientists/geologists use to study the inside of the earth?

rock samples

sand samples

seismic waves

videos of inside earth, sent by aliens

18.

1 point

Why did people reject Wegener's theory?

Not enough good evidence

People did not believe the submarine findings

He only provided one piece of evidence

Not sufficient evidence on HOW the plates moved

19.

1 point

Continental Drift is a theory that

plates move because of convection currents

Wegener used to explain Pangaea and support this evidence

that Hess created

uses technology developed post WWII

20.

1 point

Which layer is associated with molten material?

Outer core

Continental crust

Asthenosphere

Crust

21.

1 point

Which layer has rock that is soft/hard which allows this rock to bend?

Continental crust

Outer core

Asthenosphere

Inner core

22.

1 point

A trench is a result of this type of boundary

transform

convergent

tension

divergent

23.

1 point

What would you predict might happen if the core lost all of its heat?

the earth would freeze

major earthquakes would destroy earth

convection currents would stop and so would plate movement

the core would sink

24.

1 point

Which of the following are the three main layers of Earth?

Core

Lithosphere

Asthenosphere

Mantle

Crust

25.

1 point

This theory states that Earth's plates are in slow constant motion (driven by convection currents in the asthenosphere)

Sea Floor Spreading/Plate Tectonics

Continental Drift

Moving plates

Pangaea
