When southeastern rocks come in contact with air, they begin to erode, creating silt. This process often results in the formation of silt rocks which can then be buried and converted into metamorphic rocks. If this crust is removed, it can melt and come out as lava which goes through the whole process again. This process is called rock cycle.
Sedimentary rocks are formed by lava flows blown into the air by air pressure.
Eruption
When volcanic lava erupts and cools on the surface, or when molten magma pushes into existing rocks and cools to the ground, igneous rocks form. The lava is immediately affected by the weather and begins to collapse. They should come into contact with the air before the buried intruders of rocks like granite start to break down.
Erosion
When a rock breaks or is exposed on the surface of the earth, it begins to break. Wool, rain, snow, wind-blown sand, running water, and plant roots cause it to dissolve, burst, crumble, and decay. Rock debris, sand, and dissolved minerals are carried away by glaciers, rivers, or winds.
The fine silt from China's plains is carried to the sea by the Yangtze River.
New rock
The rock pile eventually settles on sedimentary beds that form on seabed, lake floors, or sand dunes. The dissolved minerals gradually solidify around the rock fragments. They combine to form new sedimentary rocks, such as sandstone and shale.
The bottom of the ocean grinds down the edges of the continents to form a mountain folded into rocks.
Upheaval
The force of plate tectonics pushes sedimentary rocks from the surface and joins them into mountain ranges. As it is pushed forward, the rocks are twisted, hardened, and restored by metamorphic slate and schisting processes. Such rocks form many of the highest peaks in the world.
Subduction
Some rocks are pushed up against the tectonic plates and some rocks are pulled into the mantle beneath the shell. Here the rocks are exposed to extreme pressures and extreme heat, which causes them to transform into rocks such as guinea fowl, migmatite and eclogite.
Meltdown
If the subduction pulls the rock down enough, it is likely to melt and form magma. This well goes towards the surface and either underground southeast infiltration occurs or erupts from a volcano. This new igneous rock begins to break as soon as it comes in contact with the air and the cycle starts again.
