Weathering and Erosion at Work

Figure 1
This is a river from a Provincial Park in Comox Valley,BC. The water level of the river rises and falls as seasons change (rain, snow melt, etc). Over time, the running water and the vegetation in and around the river act as a tool to shape the landscape.

Figure 2
This is an Egyptian spire made well over 2000 years ago (a stone column with egravings on it that tell a historical event - usually a successful battle). Over time, it's lived on 3 continents (Africa, Europe, North America), and it's beginning to show its age. [(a) What it looked like just over 100 years ago. (b) What it looked like about 20 years ago.] What do you believe is the probable cause for its surface to deteriorate so quickly? flickr:3032203866

Figure 3
These sedimentary rocks were once covered by soil. Over time the soil turned to sand, and the wind began to play a major role in exposing and shaping the rocks now

Figure 4
Taken in July, 2007 at Golden Ears Park along the Lower Falls hiking trail (Maple Ridge, BC), this picture captures some of the elements that help shape the topography of a region (a meadering river, glacial patches, flora). flickr:3032201786

Figure 5
Thousands of years ago this volcano was smoking and blowing lava all over the place. Then one day it had a massive eruption and exploded its top right off leaving a huge crater!!! It died shortly after (no longer an active volcano) , and over the years its remains collected water (precipitation and snow melt) like a bath tub. Now the volcano lives a new life as a crater
