sedimentary
No, it can form on land also. Just as long as they go through lithification
Sedimentary rocks formed under oceans, but the ocean may no longer be there. The Great Lakes region was once all under water and has much sedimentary rock.
Because of how they form and what conditions they form under.
Yes, most sedimentary rocks are formed under water. They are commonly created through processes like erosion, transportation, and deposition of sediments in water bodies such as oceans, rivers, and lakes. Over time, these sediments become compacted and cemented together to form sedimentary rocks.
Igneous rocks form because, magma cools under the ground, or magma erupts, then cools on the ground forming these rocks.
Hyperbasal Intrusive Rocks.
Rocks do not form from water.
Sedimentary rocks form on the Earth's crust, and can form metamorphic rocks when buried. Igneous rocks form under the surface, or when liquid magma reaches the surface as lava.
Intrusive igneous rocks do this.
Intrusive
Yes. That is why some rivers have rapids. Water going over rocks create them.
Metamorphic rocks are often found deep under the earth's surface because metamorphic rocks form from heat and pressure. Therefore, they form while they are under the earth's surface.
