Exploring Rock Types and Formation

Which of the following is an example of an intrusive igneous rock?

• Basalt

• Granite

• Pumice

• Obsidian

What is the primary process involved in the formation of sedimentary rocks?

• Melting

• Erosion

• Deposition

• Crystallization

Which of the following is a foliated metamorphic rock?

• Marble

• Slate

• Quartzite

• Anthracite

Explain how sedimentary rocks can transform into metamorphic rocks.

• Through melting and solidification

• By exposure to high heat and pressure

• By weathering and erosion

• Through cooling and crystallization

Analyze the differences in texture between intrusive and extrusive igneous rocks and explain how these differences arise.

• Intrusive rocks have a fine-grained texture due to rapid cooling, while extrusive rocks have a coarse-grained texture due to slow cooling.

• Intrusive rocks have a coarse-grained texture due to slow cooling, while extrusive rocks have a fine-grained texture due to rapid cooling.

• Both intrusive and extrusive rocks have similar textures due to similar cooling rates.

• Intrusive rocks have a glassy texture, while extrusive rocks have a vesicular texture.

Which of the following processes is not involved in the formation of metamorphic rocks?

• Heat

• Pressure

• Melting

• Chemical activity

Which of the following is an example of a non-foliated metamorphic rock?

• Schist

• Gneiss

• Marble

• Phyllite
