no only igneous rocks are formed when magma cools not erodes
Magma
Igneous rocks are formed when molten magma cools and solidifies either beneath the Earth's surface (intrusive) or on the surface (extrusive). Intrusive igneous rocks are formed from magma that cools slowly underground, while extrusive igneous rocks are formed from lava that cools quickly on the surface.
Igneous rocks [fire rocks] are formed either underground or above ground. Underground they are formed when the melted rock [called magma] deep within the earth becomes trapped in small pockets, and as these pockets of magma cool slowly underground the magma becomes igneous rocks. Igneous rocks are also formed when volcanoes erupt causing the magma to rise above the earth's surface. When magma appears above the earth, it is called lava. Igneous rocks are formed as the lava cools above ground. Examples of igneous rocks are granite, scoria, pumice, obsidian and basalt.
Intrusive igneous rocks are thusly formed.
igneous rock
A canyon can be formed where the water eats away on the rocks.
Magma
Intrusive igneous rocks are formed by magma. Magma can also cause the contact metamorphism of rock that it is intruded into.
Rocks are formed when magma cools and solidifies either beneath the Earth's surface (intrusive igneous rocks) or on the surface (extrusive igneous rocks). As the molten magma cools, it crystallizes and hardens into solid rocks like granite or basalt.
