Rocks and The Rock Cycle

Front

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?

Back

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

Front

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

Back

Igneous rock, because lava cools into solid rock.

Front

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?

Back

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

Front

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

Back

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

Front

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

Back

Metamorphic rock

Front

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

Back

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

Front

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

Back

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