Rocks and Minerals Knowledge Assessment

This video tutorial covers a test on rocks and minerals, starting with the properties of common minerals, including luster and hardness. It then moves on to igneous rocks, focusing on granite's characteristics. The tutorial compares sedimentary rocks, conglomerate, and breccia, and discusses coal's composition. It also explores metamorphic rocks, particularly the metamorphism of limestone. Finally, the rock cycle is explained, detailing the processes of weathering, erosion, deposition, burial, compaction, and cementation. The video concludes with a summary of the key concepts covered.

Which mineral is non-metallic and can be scratched by a fingernail?

• Fluorite

• Selenite Gypsum

• Halite

• Calcite

Which metallic mineral is harder than glass and has a green-black streak?

• Galena

• Hematite

• Pyrite

• Magnetite

Which statement about granite is false?

• It is felsic in composition.

• Its grains are 1-10 millimeters in size.

• It formed at the Earth's surface (extrusive).

• It is lighter in color than gabbro.

Which rock is black, non-vesicular, glassy, and felsic in composition?

• Obsidian

• Pumice

What is the main difference between conglomerate and breccia?

• Conglomerate contains round fragments, and breccia contains angular fragments.

• Conglomerate has larger grains than breccia.

• They have different minerals inside them.

• Conglomerate is crystalline, and breccia is clastic.
