10 Questions
What are the three major types of rocks?
The three major types of rocks are igneous rocks, sedimentary rocks, and metamorphic rocks.
What is the definition of igneous rocks?
Igneous rocks are defined as rocks that form from the cooling and solidification of molten rock.
What are the two types of igneous rocks?
The two types of igneous rocks are intrusive igneous rocks and extrusive igneous rocks.
What are the three major types of metamorphism?
Contact metamorphism, regional metamorphism, dynamic metamorphism
What is the difference between foliated and unfoliated metamorphic rocks?
Foliated rocks have distinct bands of minerals, while unfoliated rocks do not
Give an example of a foliated metamorphic rock and its industrial use.
Slate is a foliated metamorphic rock used in roof tiles and flooring
Give an example of a non-foliated metamorphic rock and its industrial use.
Marble is a non-foliated metamorphic rock used in construction, cosmetics, and paper
What are extrusive igneous rocks and how are they formed?
Extrusive igneous rocks are formed by the cooling and solidification of lava on the Earth's surface. They cool very rapidly, forming invisible crystal structures that are much smaller than in intrusive igneous rocks.
Give an example of an intrusive igneous rock and its common uses.
An example of an intrusive igneous rock is granite. It is valued for its large crystal structures and colorful grain. Granite is extensively used in making kitchen counters, floor tiles, and monuments.
What are the three types of sedimentary rocks and how are they formed?
The three types of sedimentary rocks are clastic sedimentary rocks, organic sedimentary rocks, and chemical sedimentary rocks. Clastic sedimentary rocks form from the lithification of sediments called clasts, which are produced by the weathering of other rocks. Organic sedimentary rocks form from the lithification of sediments from organic materials. Chemical sedimentary rocks form when water evaporates and produces sediments of dissolved matter.
