Metamorphic Rocks Lesson

The degree of metamorphism is often determined by studying the ___________ of a metamorphic rock.

• contact metamorphism

• foliated

• schist

• nonfoliated

• texture

They are formed when great heat and pressure are applied to rock, the rock can change both its shape and its composition

• Sedimentary Rocks

• Metamorphic Rocks

• Foliated Rocks

• Nonfoliated Rocks

What changed rocks?

• Great pressure made the rocks less rigid without melting it, and then great pressure deformed it.

• Great heat made the rocks less rigid without melting it, and then great pressure deformed it.

• Great pressure and heat made the rocks less rigid without melting it, and then great pressure deformed it.

What are the 2 kinds of metamorphic rock?

• foliated and non-foliated rocks

• intrusive and extrusive rocks

• organic and chemical rocks

• Marble or Slate

These are metamorphic rocks in which the grains are arranged in either parallel layers or bands and show the thin, flat layering

• foliated rocks

• intrusive rocks

• non-foliated rocks

• extrusive rocks

Limestone subjected to heat and pressure deep beneath the surface are formed into _______.

• conglomerate

• quartzite

• marble

• Slate

This type of rock forms from the recrystallization of existing rocks due to heat and pressure

• Sedimentary

• Metamorphic

Metamorphic rocks are grouped according to the ________ of the grains making up the rocks.

• Size

• Shape

• Arrangement

• hardness

The weakly cemented quartz particles in sandstone due to heat and pressure recrystallize to form ________.

• conglomerate

• quartzite

• marble

• Slate

These are metamorphic rocks in which the grains are arranged randomly

• foliated rocks

• intrusive rocks

• non-foliated rocks

• extrusive rocks
