Mr. R
This is incorrect. The answer is metamorphic.
Extrusive igneous rocks are one type of rocks that can be formed above the ground. Sedimentary rocks can also be formed above the ground.
There are three main types of rocks: igneous, sedimentary, and composites. Igneous rocks are formed when sedimentary or composite rocks experience extremes of heat and pressure. Sedimentary rocks are formed when smaller particles are overlaid for extended periods of time. Composite rocks are formed a mixture of elements under pressure.
They are known as Conglomerate.
Igneous rocks are formed from the cooling of magma that rises up from the mantle. Sedimentary rocks are formed from the compaction of small grains of weathered igneaous or metamorphic rock. Metamorphic rocks are formed from the action of heat and/or pressure on igneous or sedimentary rocks. Finally, subduction process at certain plate boundaries return all three rock types to the mantle. So there exists a contiuous cycle between the three types of rock; starting with igneous rocks, perhaps becoming sedimentary rock or metamorphic rock or both, then returning to the mantle.
Geologists classify rocks by looking at their chemical and mineralogical composition then at the the size and shape of their component minerals then at any texture, pattern or grain that the rocks may display. They also classify them in relation to how they were formed.
Sedimentary rocks, such as sandstone or limestone, are typically formed by processes powered by solar energy. These rocks are created through the accumulation of sediment derived from the weathering of pre-existing rocks, a process driven by the Sun's energy.

No, rocks are formed when molten magma or lava cools and solidifies. This process can occur underground (intrusive igneous rocks) or on the Earth's surface (extrusive igneous rocks), leading to the formation of various types of rocks.
Extrusive igneous rocks are one type of rocks that can be formed above the ground. Sedimentary rocks can also be formed above the ground.
The three main types of rocks found in nature are igneous, sedimentary, and metamorphic rocks. Igneous rocks are formed from the cooling and solidification of molten rock, sedimentary rocks are formed from the accumulation and compression of sediments, and metamorphic rocks are formed from the alteration of existing rocks due to heat and pressure.
Rocks are formed through a process called the rock cycle, which involves three main types of rocks: igneous, sedimentary, and metamorphic. Igneous rocks are formed from cooled magma or lava, sedimentary rocks are created from the accumulation and compression of sediments, and metamorphic rocks are formed from the alteration of existing rocks under intense heat and pressure. The type of rock formed depends on the specific conditions present during its formation.
The three main rock types are igneous, sedimentary, and metamorphic. Igneous rocks are formed from cooled and solidified magma, sedimentary rocks are formed from the accumulation of sediment, and metamorphic rocks are formed from the alteration of existing rocks due to heat and pressure. The rock cycle is a continuous process where these three types of rocks are constantly being transformed from one type to another through processes like weathering, erosion, and heat and pressure.
Extrusive igneous rocks and some sedimentary rocks are formed above ground.
Extrusive rocks, also known as volcanic rocks, are formed from magma that has cooled and solidified on the Earth's surface. These rocks tend to have small crystals due to their rapid cooling process. Common types of extrusive rocks include basalt, andesite, and rhyolite.
Rocks altered by heat and pressure beneath the Earth's surface are metamorphic rocks. These rocks are formed through the process of metamorphism, which involves the transformation of existing rock types like sedimentary or igneous rocks into new types of rocks under high temperatures and pressures. Metamorphic rocks typically exhibit distinct textures and mineral compositions as a result of this process.
Clastic sedimentary rocks are formed from the accumulation of rock and mineral fragments, while chemical sedimentary rocks are formed from the precipitation of minerals out of solution. Organic sedimentary rocks are formed from the remains of plants and animals. They differ in their composition, formation process, and appearance.
