0.6 meteres per year

It is estimated at about six feet a year.
In order to dissolve chalk in water, vinegar needs to be added. The vinegar has acid in it that eats away at the chalk to dissolve it.
How deep it is and how fast it is going downhill that can also affect it
Fast moving water will erode faster because it is more powerful than slow moving water.
A river's slope, volume of flow, and the shape of its streambed all affect how fast the river flows and how much sediment it can erode.
The sea animal that makes chalk tubes on stones and shells is barnacles. Barnacles will attach themselves to whatever is handy and multiply very fast.
Chalk, which is primarily composed of calcium carbonate, dissolves very slowly in water due to its low solubility. The rate of dissolution can vary depending on factors such as temperature and agitation. In general, it can take several hours to several days for chalk to fully dissolve in water.
A fast moving river will. This is true because in a fast moving river more sediment is picked up from theedges of the stream and the bed making the riverwider and deeper. Also more rocks will be picked up eroding the other rocks.In a slow moving river less sediment will be picked up, and the river will erode slower.Therefor the river will also pick up less rocks and or smaller rocksthat wont erode the river as fast.
It can certainly erode a cliffside, which can do a bit of damage overtime. Also, if it is a lot of water and it moves quickly, it can cause flooding.
A fast-moving water carries more sediments because it has more energy to erode and transport particles. Slow-moving water has less energy and is typically not able to carry as much sediment.
Mass movement is a fast process in the formation of landslides.Mass movement is a slow process in the formation of creep.
My sister got chalk dust in her eyes and i told her how to get it out. This is what I told her, blink really fast and you should get tears to come out of your eyes. Also, you can splash cold water on your eyes.
