b) Sedimentary
c) Metamorphic
d) All rock types

10. Question 9
What is the primary characteristic of
igneous rocks?
a) They are formed by sediment
deposition.
b) They are formed under intense heat
and pressure.
c) They crystallize from molten material.
d) They contain fossils.

11. Question 10
Which of the following processes is the
starting point for the formation of
sedimentary rocks in the rock cycle?
a) Crystallization of magma
b) Weathering and erosion
c) Melting of rocks
d) Metamorphism

12. Question 11
Which process best explains the transition
from sedimentary rock to metamorphic rock?
a) The rock is melted and then cooled
rapidly.
b) The rock undergoes high heat and
pressure without melting.
c) The rock is weathered into smaller
particles.
d) The rock cools from molten magma.

13. Question 12
Which of the following best describes how
magma is produced in the rock cycle?
a) It forms from the cooling of igneous rocks.
b) It forms when rocks are subjected to intense
heat deep beneath Earth’s surface.
c) It forms from the cementation of sediments.
d) It forms when rocks undergo erosion.

14. Question 13
In the rock cycle, how does heat and
pressure affect igneous and sedimentary
rocks?
a) They cause the rocks to melt and become
magma.
b) They cause the rocks to undergo erosion and
become sediments.
c) They transform the rocks into metamorphic
rocks.
d) They cool the rocks to form new igneous rocks.

15. Question 14
Which part of the rock cycle
directly contributes to the
formation of soil?
a) Erosion of sedimentary rocks
b) Cooling of igneous rocks
c) Compaction of sediments
d) Metamorphism of rocks.

16. Question 15
What is the primary reason why
sedimentary rocks are often layered?
a) They are formed by multiple layers of molten
materials.
b) They form through deposition of sediments
over long periods.
c) They are subject to constant pressure
changes.
d) They are melted and re-solidified in layers.
