When magma cools in … WebThe rock cycle can begin anywhere in the cycle. Lets start with igneous rocks. Igneous rocks start as magma. The magma (molten rock under the surface) and lava (molten rock on the surface) hardens into igneous rock. The igneous rock then breaks apart over time through the process of weathering.
WebMagma can either cool slowly within the crust (over centuries to millions of years) — forming intrusive igneous rock, or erupt onto the surface and cool quickly (within seconds to years) — forming extrusive igneous rock. … WebThe process begins when rocks thrust upwards by tectonic forces and eroded by wind or water. This process of erosion by wind and water is referred to as erosion and transportation weathering. The rocks ejected from beneath the earth by …
