Extrusive igneous rocks and some sedimentary rocks are formed above ground.
There are two types of igneous rocks; intrusive and extrusive. Intrusive igneous rocks are formed underneath the earth's surface from magma where it cools slower and develops large crystal structures. Extrusive igneous rocks are formed above the earth's surface from lava that cools quickly and creates rocks with smaller, finer crystal structures.
In earth
Sedimentary rocks are formed by compacting and cementation and change over time into metamorphic rocks by heat and pressure
Metamorphic rocks are formed by the pressures from inside of the Earth, They can be formed from any type of existing rock as long as it has the correct pressure applied to it. Hope this helped
All three types of rock can be formed from pre-existing rock.
Extrusive igneous rocks are one type of rocks that can be formed above the ground. Sedimentary rocks can also be formed above the ground.
Extrusive igneous rocks and some sedimentary rocks are formed above ground.
Igneous rocks are types of rocks that are formed by fire. They can be formed in the ground from magma that gets trapped in air pockets. Above ground they can form when lava cools along the ground.
Intrusive rocks are formed when rock is squeezed into underground cavities in other types of rock, where it crystallizes.
Igneous rocks are classified as either extrusive or intrusive. Extrusive rocks form from lava at or above the ground, and intrusive rocks form from magma below the ground. Granite is intrusive, pumice is extrusive.
Igneous rocks are formed from magma or lava cooling and hardening. Sedimentary rocks are formed from sediments being compressed and cemented together. Metamorphic rocks are rocks that are changed by extreme heat and pressure.
Igneous Extrusive rocks. It that too general?
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.
The types of rock and soil determines where and how much the ground shakes.
Sedimentary rocks are found generally at the bottom of an ocean as this is where eroded material falls. Igneous rocks are found near volcanoes as they are molten rock. Metamorphic rock can be found anywhere, as it is formed in the ground and slowly comes up to the surface (but it is made of igneous or sedimentary rocks.)
argillacious rocks are types of chemical rock...in this the deposition of clay take place for sure
igneous rocks are formed by cooling lava from volcanos. Obsidian is an igneous rock. Sedimentary rocks are formed by particles being deposited by water. Sandstone is a sedimentary rock. Metamorphic rocks are formed when heat, pressure, and chemical reactions change existing rocks. Granite is a metamorphic rock.
