The Rock Cycle

Front

Fill in the blank: Igneous rock forms when ______ cools and hardens.

Back

magma

Answer explanation

Igneous rock forms when magma cools and hardens. Magma is molten rock beneath the Earth's surface, and its solidification results in igneous rock, unlike sediment, water, or sand, which do not form igneous rock.

Front

What is the process by which sedimentary rock is formed?

Back

Erosion and deposition of sediments

Answer explanation

Sedimentary rock forms through the process of erosion and deposition of sediments. Over time, layers of sediments accumulate, compact, and cement together, leading to the formation of sedimentary rock.

Front

What drives the rock cycle according to the text?

Back

Tectonic activity and heat from the Earth's interior

Answer explanation

The rock cycle is primarily driven by tectonic activity and heat from the Earth's interior, which facilitate processes like melting, metamorphism, and the movement of rocks, unlike solar energy or erosion.

Front

Fill in the blank: Metamorphic rock forms when extreme pressure and heat change ______ and sedimentary rock.

Back

igneous rock

Answer explanation

Metamorphic rock forms when extreme pressure and heat change igneous rock and sedimentary rock. Igneous rock is one of the primary types of rock that can transform into metamorphic rock under these conditions.
