Front

How does the rate of cooling affect the size of crystals?

Back

Slow cooling leads to larger crystals.

Front

What are the four elements that make up gypsum in definite proportions?

Back

Calcium, oxygen, sulfur, and hydrogen.

Front

What is the difference between cleavage and fracture in minerals?

Back

Cleavage describes how a mineral splits easily along its surface, while fracture is when a mineral breaks apart in an irregular way.

Front

What causes some minerals to be more abundant than others in the Earth's crust?

Back

They are widespread and can form under common geological conditions.

Front

During crystallization, how do atoms arrange themselves?

Back

Atoms form a repeating pattern to create crystal structures.

Front

What is crystallization?

Back

The process by which atoms arrange themselves into a structured pattern to form crystals.

Front

Define a mineral.

Back

A naturally occurring inorganic solid with a definite chemical composition and a crystalline structure.

Front

What is the role of temperature in the formation of minerals?

Back

Temperature affects the solubility of minerals and the rate of crystallization.

Front

What is the significance of mineral hardness?

Back

Mineral hardness determines how easily a mineral can be scratched and is measured on the Mohs scale.

Front

What is the Mohs scale?

Back

A scale that ranks minerals based on their hardness from 1 (talc) to 10 (diamond).
