Understanding Granite and Metamorphic Rocks

The video explains how granite, an intrusive igneous rock, forms larger crystals due to slow cooling inside the Earth. When exposed to heat and pressure, granite transforms into a metamorphic rock called gneiss.

What type of rock is granite?

• Extrusive igneous

• Sedimentary

• Metamorphic

• Intrusive igneous

Why does granite have larger crystals?

• It is exposed to sunlight

• It forms on the Earth's surface

• It cools slowly inside the Earth

• It is a sedimentary rock

What happens to granite when it is exposed to heat and pressure?

• It becomes a sedimentary rock

• It melts into magma

• It transforms into a metamorphic rock

• It remains unchanged

What is the metamorphic rock that granite transforms into?

• Slate

• Marble

• Gneiss

• Quartzite

Which process is responsible for the transformation of granite into gneiss?

• Erosion

• Weathering

• Heat and pressure

• Cooling
