Rock Identification

Front

What is Coquina?

Back

Coquina is a sedimentary rock made up entirely of cemented marine shells.

Front

What type of rock is Granite?

Back

Granite is an intrusive igneous rock that forms deep inside the Earth from felsic magma that cools slowly.

Front

What is Pumice?

Back

Pumice is an extrusive igneous rock that forms when volcanic lava cools quickly and traps gas bubbles, resulting in a light, porous texture.

Front

What is Obsidian?

Back

Obsidian is an extrusive igneous rock that cools extremely fast, resulting in a glassy texture.

Front

What is Gneiss?

Back

Gneiss is a metamorphic rock formed as a result of high-grade metamorphism, characterized by its banded appearance.

Front

What is the difference between intrusive and extrusive igneous rocks?

Back

Intrusive igneous rocks form from magma that cools slowly beneath the Earth's surface, while extrusive igneous rocks form from lava that cools quickly on the surface.

Front

What is the process of sedimentary rock formation?

Back

Sedimentary rocks form through the accumulation and compaction of sediment, which can include minerals, organic material, and fragments of other rocks.

Front

What is metamorphism?

Back

Metamorphism is the process by which existing rocks are transformed into new types of rocks through heat, pressure, and chemical processes.

Front

What are the three main types of rocks?

Back

The three main types of rocks are igneous, sedimentary, and metamorphic.

Front

What is the rock cycle?

Back

The rock cycle is the continuous process of rock formation and transformation, involving the processes of melting, cooling, eroding, compacting, and metamorphosing.
