"The cliffs (of Dover on the Brittish Coast) themselves are still under attack from the sea as its continuous flow eats away at the soft chalk at the base of the cliffs. About 2-5cm on average are lost each year, but more than a metre can be lost in one large cliff fall, and as sea-levels rise the cliffs will probably retreat more quickly"...National Trust

What types of weathering affect chalk?

Chalk is primarily affected by physical weathering processes like freeze-thaw cycles and abrasion by wind or water. Chemical weathering can also occur, particularly from exposure to acidic rain or groundwater which can dissolve the calcium carbonate in chalk. Over time, these processes can cause chalk to erode and crumble.


How long does freeze thaw weathering take?

Freeze-thaw weathering is a gradual process that can occur over many years or even centuries, depending on the frequency of freeze-thaw cycles and the type of rock or material being weathered. Factors such as climate, temperature fluctuations, and the composition of the rock can also influence the speed at which freeze-thaw weathering occurs.


What is the freez thaw weathering word equation?

The word equation for freeze-thaw weathering is: Water (liquid) + Freeze (cold temperatures) + Thaw (warm temperatures) = Cracks and weathering of rocks. This process occurs when water seeps into rocks, freezes and expands, causing the rock to crack, and then thaws, repeating the cycle and breaking down the rock over time.


What is another example of freeze-thaw weathering?

Another example of freeze-thaw weathering is when water seeps into cracks in rocks or pavement, freezes overnight, expands, and then thaws during the day. This repeated process causes the rock or pavement to crack and break apart over time.


Is Physical weathering what happens in freeze thaw?

Yes, physical weathering involves the breakdown of rocks into smaller pieces through various processes, including freeze-thaw. In freeze-thaw weathering, water seeps into cracks in rocks, freezes, and expands, causing the rock to crack and break apart over time.
