Metamorphism

The video explains how heat, pressure, and dissolved minerals in hot groundwater contribute to metamorphism, a process that rearranges and sometimes changes the composition of mineral grains. This process can create new types of rocks, such as marble.

What are the primary factors that contribute to the process of metamorphism?

• Heat, pressure, and dissolved minerals

• Wind and erosion

• Freezing and thawing

• Sunlight and rain

What role do dissolved minerals in hot groundwater play in metamorphism?

• They cool down the rocks

• They contribute to the rearrangement of mineral grains

• They cause rocks to melt

• They prevent metamorphism

How does metamorphism affect mineral grains?

• It rearranges and sometimes changes their composition

• It turns them into liquid

• It dissolves them completely

• It makes them larger

Which of the following is a result of metamorphism?

• Formation of igneous rocks

• Creation of new rock types like marble

• Erosion of existing rocks

• Deposition of sediments

Which type of rock is specifically mentioned as being formed through metamorphism?

• Granite

• Limestone

• Marble

• Sandstone
