Question
Chapter 15, Problem 1LC
To determine
The main effect of weathering and of mass wasting on the landscape.
Expert Solution & Answer
Answer to Problem 1LC
Weathering leaves the landscape with broken fragments of rocks while mass wasting leaves a scar on the surface where it occurred and a bulk of debris at the bottom of the slope where the movement ceased.
Explanation of Solution
Weathering defines the in-situ process of fragmentation of rocks into even smaller pieces under the effect of some physical, chemical or biological agents. Since it causes the rocks to break down, the landscape where weathering has taken place will have numerous smaller fragments of rocks and less cohesion between them. Weathering reduces the cohesion within the composing particles of the rock to break them down.
Mass wasting is different from weathering in the sense that the former is not an in-situ phenomenon. Mass wasting describes the downslope movement of the weathered and weakly held particles of a slope under the influence of gravity. Sometimes, the materials are taken to some or a comparatively large distance, from their source area through mass wasting. It leaves a noticeable open scar on the slope from where it had begun and deposits of debris are found at the base of the slope until which the movement occurred.

Good credentials have resulted in you working in this position. The top echelon of the city government changed a few years ago, but they did not replace many staff. Nonetheless, the situation is such that the city is led by a corrupt mayor who has realized dded that elections are approaching. Opinion polls suggest that a significant part of the electorate has the environment as a major concern. Close associates of the mayor organized a focus group and chose to investigate several initiatives which they felt might be possible to conduct in a relatively short amount of time. Jual pro Metho The administration wants several projects examined. You have been tasked with conducting a cost benefit analysis on the construction of permeable pavements.

In place number one for the majority of the World's water, we have the oceans. In place number two, we have ice. Neither one is available to us for drinking water at this point.
