Exploring Types of Rocks

What are the three main types of rocks?

• Coal, Sandstone, Slate

• Basalt, Shale, Quartzite

• Granite, Limestone, Clay

• Igneous, Sedimentary, Metamorphic

Define sedimentary rock.

• Metamorphic rock is created from heat and pressure.

• Sedimentary rock is a type of rock formed from the accumulation and compaction of sediments.

• Sedimentary rock is made entirely of minerals without any sediments.

• Igneous rock is formed from volcanic activity.

Give an example of a sedimentary rock.

• sandstone

• granite

• basalt

• marble

What process forms metamorphic rocks?

• Metamorphism

• Sedimentation

• Volcanism

• Erosion

What is the main characteristic of igneous rocks?

• Igneous rocks are crystalline in nature.

• Igneous rocks are always found underwater.

• Igneous rocks are primarily composed of fossils.

• Igneous rocks are formed from sediment.

How are igneous rocks formed?

• Igneous rocks are formed from the cooling and solidification of magma or lava.

• Igneous rocks are formed from the erosion of sediment.

• Igneous rocks are formed by the compression of organic materials.

• Igneous rocks are formed through the crystallization of minerals in water.

What is metamorphosis in geology?

• The process of sedimentation in rock formation.

• Metamorphosis in geology is the transformation of rocks into metamorphic rocks due to heat, pressure, and chemical processes.

• The breaking down of rocks into smaller particles.

• The formation of igneous rocks from molten lava.

Name a common metamorphic rock.

• Schist

• Basalt

• Granite

• Limestone

What is the difference between intrusive and extrusive igneous rocks?

• Intrusive rocks have larger crystals due to slow cooling, while extrusive rocks have smaller crystals due to rapid cooling.

• Intrusive rocks are formed from lava on the surface.

• Intrusive rocks cool rapidly and are found on the surface.

• Extrusive rocks have larger crystals due to slow cooling.

How do sedimentary rocks typically form?

• Sedimentary rocks form from volcanic activity.

• Sedimentary rocks originate from the metamorphism of igneous rocks.

• Sedimentary rocks are created by the cooling of magma.

• Sedimentary rocks form from the accumulation and compaction of sediments.
