Rock Types

Which rock type is derived from the Latin word 'ignis' meaning fire?

• Sedimentary Rock

• Metamorphic Rock

• Igneous Rock

• Carbonate Rock

Igneous rocks are crystalline solids that form directly from the cooling of:

• Water

• Magma

• Sediment

• Shale

Which type of igneous rock is typically coarse-grained, showing crystal growth, because its magma cooled beneath the surface over thousands of years?

• Extrusive Igneous Rock

• Volcanic Igneous Rock

• Intrusive Igneous Rock

• Metamorphic Igneous Rock

Sedimentary rocks are often referred to as "secondary rocks" because they are formed by material that is accumulated and compacted/cemented together.

• True

• False

What is the collective name for processes that cause mineral and/or organic particles to settle and accumulate, or minerals to precipitate from a solution?

• Metamorphism

• Erosion

• Lithification

• Sedimentation

Which of the following is NOT a main type of sedimentary rock?

• Clastic sedimentary rocks

• Chemical sedimentary rocks

• Igneous sedimentary rocks

• Organic sedimentary rocks

Clastic sedimentary rocks like sandstone and shale are classified primarily based on the:

• Mineral composition

• Size of the particles

• Organic content

• Color of the rock

Which of the following is an example of an organic sedimentary rock?

• Gypsum

• Sandstone

• Gneiss

• Coal

The term "Metamorphic" comes from "meta" and "morph," meaning:

• Rock and Fire

• Change and Form

• Hard and Soft

• Earth and Heat

In most cases, the formation of metamorphic rocks involves burial which leads to a rise in:

• Mineral content

• Gravity and depth

• Temperature and pressure

• Water content
