Charmaine Farrah Estacio Geography 1 Dr. Thomas Orf 11th November 2014 ASSIGNMENT: CHAPTER 15 PRELIMINARIES TO EROSION: WEATHERING AND MASS WASTING KEY TERMS AND CONCEPTS: 1. What is meant by denudation? The total effect of all actions (weathering‚ mass wasting‚ and erosion) that lower the surface of the continents. 2. Distinguish among weathering‚ mass wasting‚ and erosion. Weathering- The physical and chemical disintegration of rock that is exposed to the atmosphere. Mass Wasting- The short-distance

Rivers and groundwater mitch baxter geography 12 jan. 29th‚ 2015 How does a river begin? Rivers begin in mountain valleys. Water at the top of the hill or mountain will take the most direct route downwards. As the water continuously flows‚ the soil beneath it becomes soggy and waterlogged. At this time‚ the soil will no longer be able to absorb any more water‚ so it will seep out onto its surface. This is the beginning of a stream that with time will evolve into a river. All water in the same drainage

Explain how each of the following landforms are formed including diagrams and annotated photographs. When a river runs over alternating layers of hard and soft rock‚ rapids and waterfalls may form Waterfalls A waterfall is a place where water flows over a vertical drop in the course of a stream or river. Landforms in upland regions are dominantly created by erosion processes‚ where land is worn away. Generally‚ the volume and discharge of rivers in upland regions tends

Theoretical background Upper course The source of the river is normally found in an area of high ground. The river usually flows through a steep V-shaped valley. Most of the erosion that occurs in the upper course is vertical and as the river bed is eroded lower the valley becomes steeper. The river is narrow with a shallow channel. As discharge is calculated by measuring the cross sectional area of the channel multiplied by the velocity‚ the discharge is small. The river is mainly slow flowing

This assignment will require you to research one natural resource and then write about your findings and conclusions in a brief paper (5 to 7 paragraphs). 1. Choose one natural resource and conduct research about it

Deforestation: Deforestation is the excessive cutting down of trees and clearing of forests for different purposes. In other words‚ it is the destruction of forests. These directly and indirectly affect us. Thus‚ deforestation is a serious type of environmental degradation. Soil erosion: Soil erosion can be defined as the destruction of the top layer of the soil as a result of natural or human activities. Soil erosion refers to the carrying away of soil. Soil erosion is also serious type of

SECTION 2-1 REVIEW AND REINFORCE •Understanding Main Ideas Answer the following questions on a separate piece of paper. 1. What factors determine whether water soaks into the ground or flows over the ground as runoff? The nature of the ground‚ the rate of the rainfall‚ and the slope of the land. 2. Draw a simple sketch of a river system. Include and label the following: headwaters. Tributary‚ oxbow lake‚ meander‚ flood plain‚ delta‚ and mouth
Premium River Geomorphology
A waterfall is a feature of erosion found in the youth stage of a river. Waterfalls are found in areas with bands of hard and soft rock (otherwise known as resistant and less resistant rocks). The hard rock takes longer to erode than the soft rock (differential erosion) so the river erodes the land at different rates. The river erodes the soft rock by the main processes of erosion including Hydraulic Action (the force and power of the moving river) and Abrasion (the scraping of the load against

To what extent do you agree that river landforms can be classified as either erosional or depositional? Many different landforms are made by either deposition or erosion and there are some cases where they can be classified as both. Erosional landforms are caused by erosion which is the breaking down and transportation of particles from one area to another. Depositional landforms are made when particles are deposited somewhere else. In my opinion I think that river landforms can be classified

Cause and Effects of the Devastation of Nature The devastation of nature is a global concern nowadays. It is because the changes that’s been done to nature which is caused mostly by human activities. When we pollute the air‚ land and water‚ this harms the nature. Bulldozing wetlands and cutting down forest also destroys the nature. These are only few of the activities that contribute to the devastation of nature. Overgrazing and groundwater pumping are some of the activities that damage
