Over a long period of time a river may display an even and progressive decrease in gradient down the valley, creating the typical smooth concave shape which has adjusted to the discharge and the load of the river. This handy set of flashcards cover the main vocabulary for this topic, with an image to illustrate each word. The diagram shows the main processes of transportation so when revising you can use it to identify and describe the four processes rather than passively reading the information shown in A. The Brainscape™ flashcard app was born out of the question: what if we leveraged this hardwiring to help students learn more efficiently? Geography is the study of the earth's features, population distribution, resources and the effects on human activities.
Larger channels tend to be more efficient; area increases to a greater degree than wetted perimeter. Flood risk during the summer is normally reduced by dry soil conditions – but in this case the record early summer rainfall meant that soils were already close to saturation. Curated by a panel of geography educators and top-performing students, Brainscape’s GCSE Geography flashcards cover the key facts you need to know for the exams, including relevant case studies and appropriate key terms.These flashcards cover the definition of ocean, sea, and gulf, as well as many of Earth's largest seas. They lie on the river bed and offer less resistance to water flow than larger particles – so much more powerful flows of water are required to lift them into the water.
In spring, meltwater causes river discharge and competence to increase, therefore the river can transport more particles. And it’s the spaced repetition of GCSE Geography content at precisely the right interval for YOUR brain that makes Brainscape so effective for remembering the facts. D eforestation in the Himalayas has had a negative effect on the rates of interception and evapotranspiration. Subdivisions of geography include; human geography, physical geography (or physiography), geomatics, and integrated geography. Each one starts off with quick questions to warm you up, followed by harder questions to get your brain into top gear.For a developing country like Bangladesh long-term responses to major floods are largely dependent on foreign aid. Concepts covered in this set of free flashcards online include the following: agriculture, food production, and rural land use; cities and urban land use; cultural patterns and processes; geography; industrialization and development; and political organization of space. Using flashcards helps with memorization through their repetition and the ability to pick out certain terms related to world geography you need to focus on. Retention basins and balancing lakes can be constructed into which water is diverted at times of high discharge. However, global warming, deforestation, and pollution are some of the modern day threats that geography is averting.
In the upper course, the channel is narrow and uneven, because of the presence of deposited boulders, Where both banks are being eroded channels tend to be broadly rectangular in shape. Deposition occurs as the velocity and sediment-carrying capacity of the river decrease on entering the lake and bedload and suspended material are dumped.
The strongest current is found on the outside of the bend and hydraulic action causes the bank to be undermined and to collapse. And remember, Brainscape's unique learning platform personalizes your studies to focus on your knowledge weaknesses, while also ensuring that you review topics you know well frequently enough so that your memory remains fresh. In the lower course, the river widens and deepens further, but banks of depositions and eyots (islands of deposition) can disrupt the shape of the channel cross-section, leading to a braided channel. The Advanced Placement Human Geography course is an exploration of how patterns and processes have shaped the way people understand, use, and change the planet. M Davies, who argued that irregularities in the long profile which would reflect changes in underlying geology are eventually worn away by river erosion to give a smooth graded profile.
