2.1 The Rock Cycle

Question 1

What are the stages of the rock cycle?

Answer 1

Weathering 
Transport and erosion
Deposition
Burial
Uplift/recrystallisation/melting

Question 2

Explain weathering?

Answer 2

The insitu break up or down of rocks due to physical

, chemical or biological processes

Question 3

Explain transport and erosion?

Answer 3

Grains are transported and are broken up due to abrasion and attrition becoming smaller and rounder
There 4 modes of transport - ice, water, gravity, wind

Question 4

Explain deposition?

Answer 4

Occurs when there is not enough energy to maintain transport

Question 5

Explain burial?

Answer 5

Layers of sediment build up causing compaction and cementation turning sediment into sedimentary rock

Question 6

Explain uplift?

Answer 6

Sedimentary rock can be pushed up to the surface again

Question 7

Explain recrystallisation?

Answer 7

Sedimentary rock recrystallises into metamorphic rock due to increase temperature and/or pressure

Question 8

Explain melting?

Answer 8

Sedimentary rock can melt into magma (intrusive or extrusive igneous rocks)
Intrusive - sills, dykes and plutons
Extrusive - columnar jointing and lava flow
Metamorphic rock can melt the same way
Partial melting can also be of mantle peridotite
