The answer is oxidation or chemical weathering. There are three main types of weathering, which includes, mechanical weathering, biological and chemical weathering. Mechanical weathering is caused by wind, sand rain, thawing, freezing, and other forces that can physically alter the rock. Biological weathering is caused by the activities of plants and animals as they grow, nests and burrow. Chemical weathering is caused by chemical reactions rather than by mechanical means.

The hormone to be given is oxytocin. Oxytocin is a hormone produced by the paraventricular nuclei of the hypothalamus then stored in the posterior pituitary gland (along with antidiuretic hormone or vasopressin) that is responsible mainly for uterine contraction and milk ejection or letdown. Oxytocin induces contraction of the myoepithelial cells in the breast for milk letdown. On the other hand, there is upregulation of oxytocin receptors during parturition which makes the uterus more sensitive to oxytocin. Oxytocin is also known to induce labor and reduce post-partum bleeding.
