EVERYDAY SCIENCE

Detailed explanation-1: -Frost Wedging occurs when water seeps into cracks of the rocks, freezes and expands, gradually breaking the rock apart into pieces. This expansion leads to the cracking of the rocks from inside and eventually breaks them apart.

Detailed explanation-2: -Physical weathering acts to widen these rock fractures. Frost wedging happens when water filling a crack freezes and expands (as it freezes, water expands 8 to 11% in volume over liquid water).

Detailed explanation-3: -Physical weathering When the ice melts, more water can get into the larger crack; if it freezes again it expands and can make the crack even bigger. Wind can cause weathering by blowing grains of sand against a rock, while rain and waves cause weathering by slowly wearing rock away over long periods of time.

Detailed explanation-4: -Freeze-thaw occurs when water continually seeps into cracks, freezes and expands, eventually breaking the rock apart.

Detailed explanation-5: -When water gets between the cracks of rocks and freezes, the rocks SPLIT OPEN. This is another cause of erosion. 5. When wind blows SAND against a mountain, the mountain erodes and the peaks become more rounded.
