Why is it difficult to see rocks change?
Rock transformations happen over thousands or millions of years, making them hard to observe directly.
What happens when sedimentary rock is exposed to extreme heat and pressure?
a) It becomes an igneous rock
b) It turns into metamorphic rock
c) It erodes into sediments
d) It melts into magma
Answer: b) It turns into metamorphic rock

a) Sedimentary
b) Metamorphic
c) Intrusive igneous
d) Extrusive igneous
Answer: d) Extrusive igneous
What type of rock is formed when magma cools slowly beneath the Earth’s surface?
a) Extrusive igneous
b) Intrusive igneous
c) Sedimentary
d) Metamorphic
Answer: b) Intrusive igneous
What is the process by which sediment is transported and deposited in new locations?
a) Compaction
b) Cementation
c) Erosion
d) Melting
Answer: c) Erosion
What happens when rocks are exposed to high temperatures?

a) Melting
b) Weathering
c) Compaction
d) Erosion
Answer: a) Melting
Which of these changes sedimentary rock into metamorphic rock?
a) Heat and pressure
b) Melting
c) Cooling and crystallization
d) Erosion
