• the crust, the upper mantle, the lower mantle, the outer core and the inner core

• the crust, the upper mantle, the lower mantle, the outer core

• the crust, the inner mantle, the outer mantle, the upper core and the lower core.

• the crust, the mantle and the heart of the Earth.

The crust is a thin layer that covers the Earth's surface. There are two types of crust, the continental crust and the _______ crust.

Due to the high pressure generated by the other layers, the inner core is:

• liquid

• semiliquid

• solid

• hot

Who discovered the outer core and the inner core?

• Richard Oldham and Inge Lehman

• No one

• Albert Einstein

• Nikola Tesla

The Earth's crust is made up of seven large plates and several other smaller ones, that fit together like a puzzle. These plates are called ________ ______.

__________ ________ produce movement of the crust and they are the reason why tectonic plates move.

The super continent that existed 325 million years ago is called:

• pangea

• pancia

• pangia

• jig saw continent

Continental drift refers to:

• the movement of the Earth's continent

• the movement of volcanoes and earthquakes

• the tendency of continents to move in random order

• the layers of the Earth

There are different types of plate boundary.

When plates move apart we refer to _________ plate boundary.
