The Igneous Rock Song!

The video tutorial discusses igneous rocks, one of the three main rock types on Earth, along with sedimentary and metamorphic rocks. It explains how igneous rocks form from molten rock, either as lava on the Earth's surface or as magma below it. The video also covers the different textures of igneous rocks, categorized into intrusive and extrusive types, and provides examples such as granite, basalt, obsidian, and pumice.

What is the primary difference between lava and magma?

• Lava forms igneous rocks, while magma does not.

• Lava is cooler than magma.

• Lava is molten rock on the Earth's surface, while magma is below the surface.

• Lava is found below the Earth's surface, while magma is on the surface.

How do intrusive igneous rocks form?

• They form from sedimentary processes.

• They form when magma cools slowly below the Earth's surface.

• They form when lava cools quickly on the Earth's surface.

• They form from the rapid cooling of magma above the surface.

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

• Slate

• Basalt

• Granite

• Marble

Which igneous rock is known for its fine-grained texture?

• Granite

• Basalt

• Pumice

• Obsidian

What is a characteristic of pumice?

• It is a type of metamorphic rock.

• It is a light and porous rock.

• It is a dense rock.

• It is formed from sedimentary processes.
