Rocks and The Rock Cycle

A geologist finds a sedimentary rock that has visible layers and is easy to break apart. What does this rock tell us about its environment of formation?

• The rock was formed under intense heat and pressure.

• The rock formed near a volcano.

• The rock formed from sediments being deposited and compacted over time.

• The rock was formed when magma cooled rapidly.

When lava cools quickly on the Earth's surface, what type of rock is most likely formed, and why?

• Sedimentary rock, because sediments settle from the lava.

• Igneous rock, because lava cools into solid rock.

• Metamorphic rock, because the heat changes surrounding rocks.

• Sedimentary rock, because the lava erodes the surface into sediments.

Sedimentary rocks are often found in layers, with older layers at the bottom. What can the arrangement of these layers tell scientists about the history of the area?

• The area was once covered by lava that cooled and hardened.

• The area experienced periods of deposition where sediments settled over time.

• The layers formed from magma cooling at different times.

• The area was subjected to intense pressure, causing the layers to fold.

What is the main difference between the formation of igneous rocks and sedimentary rocks?

• Igneous rocks form from sediments being compacted, while sedimentary rocks form from molten material cooling.

• Sedimentary rocks form from magma cooling, while igneous rocks form from sediments accumulating.

• Igneous rocks form from molten material cooling, while sedimentary rocks form from sediments being compacted.

• Both igneous and sedimentary rocks form through the cooling of magma.

A sedimentary rock is subjected to intense heat and pressure but does not melt. What type of rock will it most likely become?

• Igneous rock

• Metamorphic rock

• Intrusive igneous rock

• Magma

Which process is most likely to lead to the formation of a sedimentary rock?

• Melting and cooling of rock material.

• Weathering of rocks into smaller particles, followed by compaction and cementation.

• Exposure to intense heat deep beneath the Earth’s surface.

• Rapid cooling of magma at the Earth's surface.

How can surface processes like weathering and erosion affect the rock cycle?

• They cause rocks to change directly into magma.

• They break rocks down into sediments, which can later form sedimentary rocks.

• They increase the temperature of rocks, turning them into metamorphic rocks.

• They cause rocks to sink below the Earth’s surface and melt.
