cracks or crevices weathering may extend to considerable depths. In some cases‚ the weathering may reach as much as several hundred meters beneath the surface. This penetration is made possible by open spaces in the rock bodies and even between the mineral grains. Subsurface weathering is initiated along these openings‚ which can be penetrated by such weathering agents as water‚ air‚ and plant roots. As time passes‚ the weathering effects spread from the immediate vicinity of the openings into the denser

The rock cycle is very important to us because it explains the way the different types of rocks are formed on earth. The rocks currently visible on the Earth’s surface have moved through transition stages that transformed them from one form into another. The importance of the rock cycle lies in how it forms and recycles the various layers that make up the Earth. To do this‚ the cycle moves through three different stages that produce three different types of rock. Igneous rock makes up the foundation
