What rock types are formed above ground?

Extrusive igneous rocks and some sedimentary rocks are formed above ground.


What type of rocks form due to cooling?

The earth is composed of various types of rocks, some formed as a result of pressure while others due to cooling. Igneous rocks form when molten lava cools and solidify to form crystals.


Are all inorganic rocks formed from other rocks?

No, not all inorganic rocks are formed from other rocks. Some inorganic rocks, such as igneous rocks, are formed from the cooling and solidification of molten materials like lava or magma. These rocks do not necessarily originate from pre-existing rocks.


Which rocks would be formed above the surface of the earth?

Extrusive igneous rocks, some sedimentary rocks


Why do are some rocks flat?

Some rocks are flat because they were formed through processes like sedimentation or metamorphism, which can result in layers of sediment or minerals being compressed into flat planes. Additionally, erosion and weathering can also contribute to shaping rocks into flat surfaces over time.


What rocks are from volcanoes?

Igneous rock is the type of rock most commonly formed from volcanoes. igneous rocks may be formed from the magma underground, or form after the magma has ejected into the air. Underground, they can be formed when magma (molten rock) is trapped in small pockets and cools slowly over time. Above ground, igneous rocks are formed as the lava cools. Metamorphic rocks can be the result of volcanic activity, but they are not formed directly from volcanoes. Metamorphic rocks are the result of intense heat or extreme pressure transforming either sedimentary or igneous rocks, and these stresses can come from volcanic action, though that is not always the case.


How are metamorfic rocks formed?

formed by immense heat and pressure


What are some examples of rock types?

Igneous rocks - rocks formed from molten rock of the mantle Sedimentary rocks - rocks found in streams Metamorphic rocks - rocks changed by the effects of heat and pressure


How coaral reefs are formed?

They are formed in the ocean. By some rocks and plants. Put on for hundreds of years.


What are some igneus rocks?

some igneus rocks are Granite,Basalt,Pumice,Obidan,and Rhyolit.


What rocks are not formed by the rock cycle?

Artificial rocks, such as concrete or bricks, are not formed by the natural rock cycle. These rocks are man-made through processes like mixing cement, shaping, and hardening. They do not undergo the typical geological processes like weathering, erosion, and lithification that form natural rocks.


Are minerals always formed from cooling magma or lava?

No. Some minerals in sedimentary rocks are formed from chemical reactions at the surface or precipitate out of solution. Most deposits of calcite and aragonite are from the shells of living organisms. Minerals in metamorphic rocks form as a result of solid-state chemical changes under heat and pressure, or from reactions with hot water.
