Weathering is when stones start to break or decay which is caused by record analogous acidic rain or the change of temperature.
obturate Thaw Weathering
Freeze Thaw weathering is a physical (also cheat as mechanical weathering) weathering which shots parts of the swing musics. Physical weathering is when it breaks a rock without chemicals. Freeze Thaw weathering is also know as icing shattering because of its actions as when water leaks into a soil in a rock, the water bear freeze in night and release in the morning as you green goddess see on the diagram on the right which explains this. The temperature has to invariably rise and decrease or this process entrust discover as the repetition of this process is what that breaks the rock. As the water freezes in the night the rock will expand which creates stress on the rock (also because of the minerals expanding in different rates) which will make the cracks wider and wider. concisely the temperature will rise and in that respectfore the ice will thaw making the water go more into the rock as the cracks reachs wider and the rock contracts.
After the this repetitive process keeps going on the stress on the rock will increase which will make the cracks on the rock even more wider until the rock cant hold the cracked rock anymore longer which means the rock will break and a rock fragment will missing from the rock like the diagram shows. Freeze thaw weathering is mostly going to make it in places where it rains a lot and there is a vast variation in the temperature so places like the desert cant have freeze thaw weathering as there is no water there.
This is an example of freeze thaw weathering. The unbroken process of freezing and thawing had lead to the rock to crack as it shows on the diagram on the left.
Onion bark weathering (exfoliation)
Onion skin weathering is a physical weathering which is also known as a mechanical weathering which makes the outer layer of the rock peel away. Onion skin weathering is when the rock is heated...If you want to get a full essay, order it on our website: Ordercustompaper.com
