Weathering is the process by which rocks are gradually broken down in situ. Erosion is the breaking down of rocks and being removed by weathering agents e.g. water and winds.Physical weathering is more effective in areas which have : a little vegetation/a large diurnal range of temperature or/temperatures fluctuating around 0 degrees Celsius

When the water evaporates , the salts are left behind as crystals. The build-up of the salt crystals creates stress in the rock, weakens it and breaks it down into grains.
