Rocks Quiz

Which type of rock is created by the transformation of existing rock types through high pressure and temperature?

• Igneous rocks

• Sedimentary rocks

• Metamorphic rocks

• Volcanic rocks

What is the first step in the formation of sedimentary rocks?

• Compaction of layers

• Cementation by salt crystals

• Erosion of sediments into water

• Formation of rock mass

During the formation of sedimentary rocks, what is the role of salt crystals?

• They erode the sediments

• They pile up to form layers

• They glue the layers together

• They compact the sediments

What are clastic sedimentary layers formed by?

• The accumulation of volcanic ash

• The erosion and accumulation of small broken bits of rock

• The compaction of animal bones

• The solidification of molten lava

What type of igneous rocks are formed from magma that cools quickly and are fine grained?

• Intrusive igneous rocks

• Metamorphic rocks

• Sedimentary rocks

• Extrusive igneous rocks

What causes the formation of metamorphic rocks?

• Cooling of magma or lava

• Deposition of mineral grains

• Intense heat or pressure

• Erosion of mountains

How does limestone transform under intense heat and pressure?

• It becomes granite

• It becomes sandstone

• It becomes marble

• It becomes slate

What is the process that breaks down rocks into smaller pieces, eventually forming sediments?

• Compaction

• Cementation

• Weathering and Erosion

• Melting

Which process involves the movement of rocks from the Earth's surface towards the core due to tectonic forces?

• Sedimentation

• Weathering and Erosion

• Uplifting

• Heat and pressure

When rocks are affected by weathering and erosion, they change into which of the following?

• Lava

• Magma

• Sediment

• Coal
