Abstract

About one third of Earth's land surface is either arid (< 10" ppt./yr or semi-arid (10" to 20" pt./yr). While most precipitation is in the form of rain, some may be provided by melting snow, mist, or fog. With limited availability of water, rocks are not subjected to chemical weathering but rather to physical weathering.
