Question 1

1 mark

Based on the rock cycle, what is the internal process that leads to the formation of igneous rocks?

Question 2

1 mark

A geological diagram shows the interaction between the lithosphere, atmosphere, and hydrosphere. Which part of the rock cycle involves all three systems simultaneously?

Question 3

1 mark

Consider a massive batholith located deep within the lithosphere. For this rock to eventually become part of a conglomerate (a sedimentary rock), which sequence of geological events must occur?

Question 4

Explain how increased heat and pressure lead to the formation of new minerals and textures in metamorphic rocks.

Write your answer out first, then check it against the worked solution.

Question 8

6 marks

Explain the role of plate tectonics in driving the rock cycle, specifically focusing on the formation of metamorphic rocks.

Write your answer out first, then check it against the worked solution.

Question 9

2 marks

Explain the significance of burial as a process in the formation of sedimentary rocks within the rock cycle.

Write your answer out first, then check it against the worked solution.

Question 10

8 marks

a) Explain how divergent plate boundaries lead to the formation of igneous rocks, detailing the magma generation process and the typical rock types produced.

b) Describe the different mechanisms of magma generation and subsequent igneous rock formation that occur at convergent plate boundaries, distinguishing between oceanic-oceanic and oceanic-continental convergence.

c) Compare the chemical compositions and eruption styles of igneous rocks typically formed at divergent boundaries versus convergent boundaries, explaining how these differences relate to the specific tectonic settings.
