Detailed explanation-1: -Water is a very important part of the physical weathering of rock. Which of these properties of water is MOST important in causing some of the physical weathering of rock? Water expands when it freezes.
Detailed explanation-2: -Physical weathering occurs when physical processes affect the rock, such as changes in temperature or when the rock is exposed to the effects of wind, rain and waves. Water can get into cracks in a rock and, if it freezes, the ice will expand and push the cracks apart.
Detailed explanation-3: -When water freezes, it expands. The ice then works as a wedge. It slowly widens the cracks and splits the rock. When ice melts, liquid water performs the act of erosion by carrying away the tiny rock fragments lost in the split.
Detailed explanation-4: -Physical weathering can occur due to temperature, pressure, frost, root action, and burrowing animals. For example, cracks exploited by physical weathering will increase the surface area exposed to chemical action, thus amplifying the rate of disintegration.
Detailed explanation-5: -Which of the following characteristics of water can be responsible for mechanical weathering? Water reacts with and can dissolve many kinds of minerals.
