Yes, because the ion chloride (Cl-) is corrosive.
Salt water will erode earth material much more quicker.
Some rocks are harder than others like sandstone which is very soft. Other times rock can have different conditions under which they will erode faster such as limestone.
Sedimentary rocks tend to erode easily compared to other types of rocks as the grains within them are farther apart than the "grains" in, let's say, igneous rocks. As a result of this, the "grains" can be easily crumble. An example of this is sand.
Yes, granite can erode, albeit very slowly, as it is a very srong, hard rock. All naturally occurring rocks will erode, given time
Its actually more about the composition of the rock than the shape, the rounded rocks tend to be of a softer material such as sandstone, limestone etc which erode quicker and as such form into rounded shapes were harder rocks such as granite are more resistant to erosion and therefore its the softer materials that erode and leave the sharp edges of granite.
Lichens and mosses erode rocks by producing acids. These acids lead to the deterioration of rocks, such as limestone and marble.
obsidian
well, think about it, wind can erode ALL size of rocks, wind does its job, which is eroding rocks.
Gold is a solid material that doesn't erode with salt and doesn't react with anything, it has no reactants.
all of them
We ( as in humans and animals as one) erode the earth by digging it up, and building over it. Also, our pollution increasing the process of eroding. It does that by the increase in acid rain, from pollution, which erodes rocks much faster.
It divides Britain into hard and softer rock types. The softer rocks in the south-east erode faster. In the north west are older harder rocks such as granite and basalt.
