Energy Transfer In Natural System

Question 1

Outer core

Answer 1

Outer core is the layer below the earths mantle

Question 2

Inner core

Answer 2

Earths solid centre

Question 3

Asthenosphere

Answer 3

A partly molten layer in earths upper mantle just below lithosphere

Question 4

Mantle convection

Answer 4

The driving force behind tectonic plate moment. It works when cold manga rises then gets cold and then gets hot again. Sort of like a circle

Question 5

Plate boundary

Answer 5

The region where two tectonic plates are in contact

Question 6

Divergent plate boundary

Answer 6

A region where tectonic plates are spreading apart

Question 7

Rift valley

Answer 7

A steep sided valley formed on land

Question 8

Ridge push

Answer 8

A process in which tectonic plates push apart old material and creating new ones

Question 9

Rift eruptions

Answer 9

Volcanoes that occur where magma erupts through long cracks

Question 10

Convergent plate boundary

Answer 10

Region where tectonic plates are colliding

Question 11

Subduction

Answer 11

When one tectonic plate is forced under another

Question 12

Mantle

Answer 12

Earths thickest layer. Makes up 70 percent of the earths volume

Question 13

Slab pull

Answer 13

The pulling of a tectonic plate as its edge subduction deep into the mantle

Question 14

Volcano belt

Answer 14

A long chain of volcanoes

Question 15

Composite volcanoes

Answer 15

Large cone shape volcano. Very explosive. Thick magma but not very big volcano

Question 16

Shield volcano

Answer 16

Largest but not very tall. Magma is formed from deeper in the earth. Less explosive. Found in oceans

Question 17

Rift volcanoes

Answer 17

Looks like a curtain. Less explosive, lots of lava. Forms in cracks

Question 18

Volcanic island arc

Answer 18

A long chain of volcanic islands

Question 19

Focus

Answer 19

A location where the earthquakes happen (the exact tension)

Question 20

Epicentre

Answer 20

Area directly above the focus
