Rocks and Minerals

What are Rocks?

Rocks are solid materials that make up the Earth's crust. They are composed of minerals, and can be classified into three main types: igneous, sedimentary, and metamorphic.

Types of Rocks

• Igneous Rocks: Formed from the cooling and solidification of magma or lava. Examples include granite and basalt.
• Sedimentary Rocks: Formed from the accumulation and compression of sediments. Examples include limestone and sandstone.
• Metamorphic Rocks: Formed from the alteration of existing rocks through heat and pressure. Examples include marble and slate.

What are Minerals?

Minerals are naturally occurring, inorganic substances with a specific chemical composition and crystal structure. They are the building blocks of rocks and are classified based on their chemical composition.

Identifying Minerals

Minerals can be identified based on their physical properties, including color, luster, hardness, cleavage, and streak.

Importance of Rocks and Minerals

Rocks and minerals have a significant impact on our daily lives. They are used in construction, manufacturing, and even in technological devices. Understanding their properties and characteristics is important for various fields, including geology, engineering, and environmental science.
