Concetti Chiave
- Igneous rocks form from intense underground heat and solidified lava, with granite being a notable durable and water-resistant material.
- Sedimentary rocks originate from the accumulation of sediments deposited by wind and water, including limestone and sandstone.
- Limestone and sandstone often contain fossilized remains, with sandstone being more resistant to pollution than limestone.
- Metamorphic rocks result from the transformation of igneous and sedimentary rocks, with slate and marble as common examples.
- Marble, a metamorphic rock formed by chemical processes, is prized for its color and decorative uses.
Rocks
Igneous rocks are the types of rock goes back to millions years ago and they derive of intense underground heat and of the solidification of the lave.
The most important material derived by igneous rock is granite. Granite is a material very durable and water resistant.
Sedimentary rocks are the result of sediments of other rock. this material is deposited by winds and waters. Limestone and sandstone are the material derivation by sedimentary rocks.
Metamorphic rocks are formed by transformation of igneous and sedimentary rocks. Slate and marble are metamorphic rocks. This types of metamorphic rock are trained by chemical process. Marble has a different color and it is used for decorative purposes.
