NCERT Solutions for Class 11 Geography Chapter 5: Minerals and Rocks 🪨

NCERT Solutions for Class 11 Geography Chapter 5 – Minerals are naturally occurring, inorganic substances found in the Earth’s crust. They have a specific chemical composition and crystalline structure. Some minerals are valuable—think gold, diamonds, and emeralds—while others are less glamorous but still important, like clay and salt. These minerals are the raw materials for everything from jewelry to construction materials.

Types of Rocks: From Hot Lava to Solid Stone 🌋

Rocks are made up of one or more minerals. They’re categorized into three types based on how they form: igneous, sedimentary, and metamorphic.

1. Igneous Rocks: Formed from the cooling and solidification of magma or lava. Examples include granite and basalt. 🌋
2. Sedimentary Rocks: Formed by the accumulation of sediments. They’re often layered and include rocks like sandstone and limestone. 🌱
3. Metamorphic Rocks: These rocks are formed from existing rocks that undergo heat and pressure. Marble, for example, is a metamorphic rock that originates from limestone. 🏔️

Each of these rock types has its own unique characteristics, and understanding them helps geologists unlock the history of our planet.
