Explanation

Question 8 of 18

1

Select from the dropdown lists to complete the text.

The ( core, heart ) of the Earth is a ball of ( solid, liquid ) (inner) and ( liquid, solid ) (outer) iron and nickel.

Around the core is the ( mantle, outer layer ), which is semi-molten rock that moves very ( slowly, quickly ).

The outer layer of the Earth is the ( crust, surface layer ). The ( crust, surface layer ) is divided into slabs called ( tectonic, boundary ) plates (that float on the mantle).

Plates are made up of two type of crust: ( continental, constructive ) and ( oceanic, destructive ).

The places where plates meet are called plate ( margins, collisions ) or plate ( boundaries, gatherings ).

Explanation

Question 9 of 18

1

What are the three different types of plate margin?

Select one or more of the following:

Destructive
Continental
Constructive
Conservative
Oceanic

Explanation

Question 10 of 18

1

Select from the dropdown lists to complete the text.

( Destructive, Constructive ) margins occur where two plates are moving towards each other. When a ( continental, destructive ) plate meets an oceanic plate, the oceanic plate is forced down into the ( mantle, crust ) and destroyed. When two ( continental, oceanic ) plates meet the plates collide, fold and are forced ( upwards., downwards. )

( Constructive, Conservative ) margins occur when plates are moving away from each other. This causes ( magma, lava ) to rise and cool, filling in the gap and creating new ( crust, mantle ).

( Conservative, Constructive ) margins occur when plates move ( sideways, upwards ) past each other, or move in the same direction but at different ( speeds, pressures ). Crust is not ( destroyed or created, destroyed or moved, damaged or moved ).

Explanation

Question 11 of 18

1

Volcanoes are found at destructive and constructive plate margins.

Select one of the following:

True
False

Explanation

Question 12 of 18

1

At a destructive margin the ❌ plate is forced downwards into the mantle, where it is melted and destroyed. This forms a pool of ❌, which then rises through cracks in the crust known as ❌. The magma then erupts onto the surface of the earth (where it is now described as ❌) and forms a ❌.

At a constructive margin the magma rises up into the gap caused by plates ❌, creating a volcano.

Volcanoes can also form over parts of the ❌ that are extremely hot. These areas are known as ❌.

Question 13 of 18

1

At which type(s) of plate margin do earthquakes occur?

Select one of the following:

All three types of plate margins
Two types of plate margins: constructive and destructive margins
One type of plate margin: conservative margins

Explanation

Question 14 of 18

1

Earthquakes are caused when plates get stuck and have to jerk past each other. As they move past each other vibrations (also known as shock waves) are sent out, which form the earthquake.

Select one of the following:

True
False

Explanation

Question 15 of 18

1

The focus of the earthquake is on the Earth's surface.

Select one of the following:

True
False

Explanation

Question 16 of 18

1

Which three types of scales are used to measure earthquakes?

Select one or more of the following:

Moment magnitude
Lester
Richter
Mercury
Mercalli
Logarithmic

Explanation

Question 17 of 18

1

When a volcano erupts, what can it emit?

Select one or more of the following:

Lava
Magma
Gases
Ash
Rocks
