Geology and Rocks: Exploring the Fascinating World Beneath Our Feet

🌍Geologists study the Earth's structure, its formation, and changes over time.

🧱Rocks can be classified into three main types: sedimentary, metamorphic, and igneous.

🌋Sedimentary rocks are formed from particles of sand, shells, and other materials, while metamorphic rocks undergo intense heat and pressure beneath the Earth's surface.

💡Igneous rocks are formed from cooled magma, either inside the Earth (intrusive) or on the surface (extrusive).

🌱Geologists play a crucial role in studying human-environment interactions and promoting sustainable practices.

What do geologists study?

—Geologists study the Earth's structure, how it was formed, and how it has changed over time.

What are the three main types of rocks?

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

How are sedimentary rocks formed?

—Sedimentary rocks are formed from particles of sand, shells, and other materials that have been compacted over time.

How are metamorphic rocks formed?

—Metamorphic rocks are formed when existing rocks undergo intense heat and pressure within the Earth's crust.

What are igneous rocks?

—Igneous rocks are formed from cooled magma or lava. They can be classified as intrusive or extrusive based on where they solidify.
