Rocks

What are the three major types of rocks based on their formation?

• Igneous, Sedimentary, and Metamorphic

• Volcanic, Oceanic, and Continental

• Hard, Soft, and Medium

• Primary, Secondary, and Tertiary

How are igneous rocks formed?

• From compressed sediments

• From molten matter cooling and solidifying

• From existing rocks undergoing high pressure

• From organic matter decomposition

What are sedimentary rocks primarily comprised of?

• Molten lava

• Minerals, small pieces of plants, and organic matter

• Only large rock fragments

• Only solidified magma

What happens to igneous and sedimentary rocks during metamorphism?

• They melt completely

• They are compressed and deposited over time

• They undergo change due to high temperatures and pressures without melting

• They are broken down into smaller pieces

Which of the following is an example of a metamorphic rock mentioned in the video?

• Pumice

• Sandstone

• Marble

• Coal
