Rocks and Rock Cycle

Front

What is the process necessary to form a metamorphic rock?

Back

Heat and/or pressure.

Front

What does the Law of Rock Superposition state?

Back

New layers of sediment settle on top of older layers of rock.

Front

What is compaction in the context of the rock cycle?

Back

The process when rocks are deeply buried, placing them under pressure due to the weight of overlying layers.

Front

Which type of rock is considered the youngest in a sequence?

Back

The topmost layer, such as Sandstone.

Front

Why is Granite labeled as an intrusion?

Back

It cooled internally without reaching the surface.

Front

What is lithification?

Back

The process of turning sediment into rock through compaction and cementation.

Front

Define sedimentary rock.

Back

Rocks formed from the accumulation and compaction of mineral and organic particles.

Front

What is the role of erosion in the rock cycle?

Back

Erosion breaks down rocks and transports sediments to new locations.

Front

Explain the term 'metamorphism'.

Back

The process by which existing rocks are transformed by heat, pressure, or chemically active fluids.

Front

What is the difference between intrusive and extrusive igneous rocks?

Back

Intrusive rocks cool slowly beneath the surface, while extrusive rocks cool quickly on the surface.
