ROCKS and MINERALS for Kids - What are their differences? - Science for Kids

Rocks are the solid parts of the earth, made up of different elements called minerals. Rocks are formed from combinations of minerals that have developed naturally over time.

Rocks are classified into three types based on their origin: igneous, sedimentary, and metamorphic. Examples include granite rock, coal, and marble. Petroleum, despite being liquid, is also considered a rock formed from the remains of living things and sediment deposits. Rocks are extracted from quarries or mined underground.

Minerals vary greatly and possess important physical properties such as hardness, shape, luster, and color. Examples include diamond (the hardest mineral), talc (the softest mineral), quartz (which can be white or pink), and gold (a very shiny material).

Since prehistoric times, people have utilized rocks and minerals for various purposes, including making utensils, building houses, paving, and creating beautiful jewelry. An activity is suggested to create an exposition of rocks and minerals, labeling them with details like name, photo, location, color, texture, and hardness.
