Some of the man made features in this world are very well visited places. But when you look deep into the matter you will always find that people are almost always more intrigued by the power of nature to mold things. One example of this fact is the seven sisters. Seven Sisters are in fact a range of chalk cliffs. These chalk cliffs are located very near the English Channel. This part of the world is included in the Southern England. The Seven Sisters are located between two towns. The town of Seaford and the town of East Bourne are the two towns between which these Seven Sisters are standing. Theses are also known as the white cliffs. The chalk cliffs are being eroded by the sea at a very fast pace. This is the biggest problem with chalk topography. Water makes amazing changes in these features and makes them beautiful. But there are equal chances of getting destroyed by the water erosion with the passage of time. Although all kinds of rocks get eroded after sometime, but the chalk topography is the most vulnerable to water erosion.
