What is a sedimentary rock?

Back

A type of rock that is formed by the accumulation and compaction of mineral and organic particles, often found in layers. Example: sandstone.

What are the three main types of rocks?

Back

Igneous, metamorphic, and sedimentary.

Front

How do igneous rocks form?

Back

Igneous rocks form from the cooling and solidification of molten rock (magma or lava).

Front

What is the rock cycle?

Back

The rock cycle is the continuous process of rock formation and transformation, involving igneous, sedimentary, and metamorphic rocks.

What is an igneous rock?

Back

A type of rock that forms from the cooling and solidification of magma or lava.

Front

What is a metamorphic rock?

Back

A type of rock that has changed from its original form due to heat, pressure, or chemical processes.

Front

What is the difference between granite and basalt?

Back

Granite is a coarse-grained igneous rock, while basalt is a fine-grained igneous rock. Both are formed from cooled magma.

Front

What conditions are necessary for metamorphic rocks to form?

Back

Metamorphic rocks form under conditions of high heat and pressure.

Front

What is erosion?

Back

Erosion is the process by which soil and rock are removed from the Earth's surface by natural processes such as wind or water.

Front

What is compaction in the context of sedimentary rocks?

Back

Compaction is the process by which sediments are pressed together under their own weight, leading to the formation of sedimentary rocks.
