there is no such hard rocks can't possibly break, at one time according to the time the stone are definitely breakable pieces, thus going beyond to the rock becomes smooth, the process of the destruction of the stones of this kind are called "damage or worn out by the weather".
this goes on continuously throughout the period by sharing sort of way, glister-glister push the pile of fallen rocks in great abundance when the glide glister down, the process of push and grind the rocks that it helped destroy the rocks it becomes smooth.
water containing chemical substances in self will make melting and washed away several types of stones, the changes in temperature are also often help solve the stones of it being melted, the process of heater and cooling rocks that can cause cracked on layer of rocks, the water will sink fit into rock through cracks-cracks it, and water will freeze there and thus add to the rocks that grew fractured again, even the roots of vegetation can lead to stones that broke.
sometimes the seeds the plants fall into the cracks the rocks that, when plant roots that grow, then the root of the vine and help solve the stones, and helped destroy the rocks is the wind, by way of filing the rocks it with dashes of sand.
but what is described is just a beginning of the way land was formed, to acquire land in the sense that in real, then the particles to rocks that have become a smooth send must be coupled with the blowing "humus".
