Metamorphism and Rock Transformation Concepts

The video tutorial covers contact and regional metamorphism, explaining how heat and pressure from magma and tectonic plate interactions transform rocks. It details the processes and examples of rock transformations, such as sandstone to quartzite and limestone to marble. The tutorial also discusses the effects of pressure on rock density, emphasizing the impermeability of metamorphic rocks.

What are the two main types of metamorphism discussed in the video?

• Static and dynamic

• Thermal and dynamic

• Contact and regional

• Chemical and physical

What causes contact metamorphism?

• Pressure from tectonic plates

• Heat from magma

• Erosion by water

• Wind abrasion

Which rock can sandstone transform into through contact metamorphism?

• Gneiss

• Marble

• Slate

• Quartzite

What geological process is primarily responsible for regional metamorphism?

• Volcanic eruptions

• Wind erosion

• Tectonic plate collisions

• River sedimentation

Which type of metamorphism affects a larger area?

• Contact metamorphism

• Thermal metamorphism

• Dynamic metamorphism

• Regional metamorphism

What is the parent rock of slate in the transformation sequence?

• Granite

• Limestone

• Shale

• Sandstone

Which rock is formed from bituminous coal under heat and pressure?

• Peat

• Graphite

• Anthracite coal

• Diamond

What happens to the density of a rock when pressure is increased?

• Density decreases

• Density fluctuates

• Density remains the same

• Density increases

In the density demonstration, what happens to the volume when pressure is applied?

• Volume fluctuates

• Volume increases

• Volume remains constant

• Volume decreases

Why are metamorphic rocks generally impermeable?

• They have high porosity

• They are loosely packed

• They are highly compressed

• They contain many fractures
