In this video, we will go over one of the exogenic forces: weathering. Weathering can happen in two ways: there is Mechanical weathering and Chemical weathering.
We will go over 3 types of Mechanical weathering; The first is caused by freezing water; The second is caused by big temperature differences; The third is caused by flora (aka: plant roots).
We also go over the sedimentary rock that is most affected by chemical weathering: Limestone. And that large areas that are made from limestone can become a Karstlandscape over time.
This video is used for a 2 VWO bilingual class with the help of the books from BuiteNLand.
And as always: sit back, relax, enjoy, but most of all, learn something new
