Structure Of The Earth

Question 1

What are the different layers of the Earth

Answer 1

• innercore
• outer core
• Mantle
• Crust

Question 2

What is the inner core

Answer 2

• made of iron and nickel
• as hot as the surface of the sun

Question 3

Outer core

Answer 3

• made of Iron and nickel
• liquid form of inner core

Question 4

Mantle

Answer 4

• made of magma and molten rock
• thickest part of the Earth

Question 5

Crust

Answer 5

• layer of solid rock that we live on
• very thin

Question 6

Tectonic plates

Answer 6

• Where the earth a has cracked and split into different pieces
• they are moved around fuelled by energy from the hot mantle
• made of either oceanic or continental crusts

Question 7

Oceanic crust

Answer 7

Tectonic plates which are found mainly under oceans

Question 8

Continental crust

Answer 8

Tectonics plates which are found mainly under land

Question 9

Destructive/convergent plate boundary

Answer 9

• a plate margin that involves an oceanic and continental plate
• moves towards each other
• the oceanic plate is forced underneath the continental plate
• this is known as subduction

Question 10

Constructive/divergent plate boundary

Answer 10

• where plate margins move away from each other and mantle separates
• usually found under oceans

Question 11

Conservative plate margin

Answer 11

• where two tectonic plates slide past each other
• friction causes them to get stuck
• pressure build up until friction is overcome
• usually under oceans

Question 12

Collision plate margins

Answer 12

• where two tectonics plates both push together and move above
• usually happens in continental plates
