Igneous and Metamorphic Rocks: Foliated and Nonfoliated Metamorphic Rocks

The video tutorial discusses slate, a metamorphic rock used for roofing, derived from shale. It explains how slate's foliation, caused by heat and pressure, makes it ideal for roofs. The video contrasts foliated rocks like slate and schist with non-foliated rocks like marble, highlighting differences in structure and breakage patterns.

Which metamorphic rock is commonly used for roofing due to its ability to split into flat sheets?

• Marble

• Slate

• Granite

• Limestone

What is the original sedimentary rock from which slate is formed?

• Sandstone

• Conglomerate

• Limestone

• Shale

What process causes the grains in slate to align in parallel bands?

• Crystallization

• Sedimentation

• Foliation

• Erosion

Which of the following is a foliated metamorphic rock?

• Basalt

• Schist

• Marble

• Quartzite

How does marble differ from slate in terms of its structure?

• Marble is derived from shale, while slate is not.

• Marble is non-foliated, breaking in uneven fragments.

• Marble breaks along flat bands, while slate does not.

• Marble is foliated, while slate is not.
