Question

Review the water chemistry data for Cedar Creek (see below). What information does this data provide about the influence of geology on water chemistry? Is there evidence that rock weathering is contributing to the chemical composition of the water? (answer in approx. 200 words)

Explanation / Answer

The following table gives information regarding various elements concentration and the concentration of these elements in the upper creek and lower creek. These elements change the chemical composition of water because water consists of certain elements which must be present in desirable amount so that water retains its identity. If the elemental composition is changed,the pH level of water may also change. The level of elements in the upper level and lower level varies greatly and this greatly influence the chemical properties of water.

Rock weathering is nothing but the carrying and deposition of rock particles due to wind and other watery action. The particles may get deposited in rivers,oceans etc and the minerals in rocks may get mixed up with water and change the composition.
