Suspension is slightly different, but it might help you if you imagine that the particles involved in suspension are a tiny bit heavier than soluble particles. If you are offered a cross profile diagram of a V-shaped valley with steep sides and what appears to be a small amount of water in the bottom, then that usually means that you are looking at the upper course of a river, where the gradient is steep. The description of each landform is supported by diagrams and key terminology. system.

As rivers flow, they pick up material. OCR A Level Geography, AQA A Level Geography Past Papers If you take a look at a cross profile diagram of a river, then it is easy to see that rivers widen at certain points. We can also see attrition occurring. When we are talking about both vertical erosion and lateral erosion, there are four key factors that come into play: As you can see, one of the main causes of erosion actually occurs because of materials that are being transported downstream. AQA GCSE Geography This is where some types of rock are dissolved. The lower course is the last course of a river. Covering KS3, GCSE and A-Level, we provide the most comprehensive GCSE and A-Level revision tools to pass your exams. The river here is smaller and usually has a rapid, tumbling flow that cuts a narrow channel through rocky hills or mountains. Square This is the part of the river closest to the source. You can edit all written passages. They usually start off narrow in the upper course, so a wide river tells us that we are looking at either the middle course or the lower course. CIE A Level Geography When rivers flood the velocity of water slows. The cross profile simply shows us a cross-section of the river, while the long profile shows us how the gradient changes over the course of the river. Rivers usually have a wide, smooth channel, and water moves at its slowest. Post class homework and consolidation- Likewise, the resources could be used to consolidate on in-class teacher instruction.

When we refer to rivers that flow downhill, we call the path that they follow their course. By the time a river reaches the lower stretches of its long profile – and gets closer to base level (usually sea level, though possibly a lake) – the channel can experience an increase in deposition. This material can then scrape along the sides of the channel. Includes application through the consideration of planning on flood plains (zonation). In class activity- I use this resource to quickly and accurately teach the subject knowledge. In this part the slope of the river bed is not very steep. Activate- a starter, an introduction, a stimulus. The area over which they flood is known as the floodplain, and this often coincides with regions where meanders form. In the upper stage, the river is close to its source and high above its base level (the lowest point the river can erode to 1).In the lower stage the river is far away from its source, close to the mouth and not far above its base level.

Any river, anywhere in the world can be split into three sections. Tributary- Smaller rivers/streams that join the main river. In the lower course, the river has a high volume and a large discharge. Through looking at these diagrams, it is easier to understand the nature of V-shaped valleys, the river ordering system, the water cycle and other aspects related to rivers. Deposition is the main activity of a river at this stage. Saltation involves particles that are too heavy to be simply carried along by the water.

If so, you can save yourself a lot of time by downloading our modules below.

The description of each landform is supported by diagrams and key terminology. After a series of floods layers of sediment form along the flood p… I’ve found that the resources help to free up time for application and higher order thinking skills. The silt and other materials carried by the river are deposited. This means that you can add around this. They are still carried along in the water, but in a dissolved state. I have deliberately focused on key knowledge and processes. Now that you know what happens during erosion and transportation, it is important to learn what happens to all of these particles and where they actually end up.

You can control the learning objectives, you can add video clips, your own activities etc. Nearly all rivers have an upper, middle, and lower course.

Deposition can occur for a few different reasons. We can usually see the most vertical erosion in the upper course.

The sheer force of the water in the river breaks rock particles away. Review- a plenary, recall activity, AFL, knowledge check. We can usually use the cross profile to identify whether we are looking at the upper course, middle course or lower course of a river. Locating the world's famous volcanoes - KS2, Identifying the key features of mountains, Volcanoes and other Natural Disasters - Presentation. Use the resource as a framework. Previously taught in a 1hr lesson. There is a thinking skills activity based on land use on floodplains. If you are offered a cross profile diagram of a valley that appears to have sides that slope gently and quite a deep channel of water in the bottom, then that usually means that you are looking at the middle course of a river, where the gradient is medium. The former is closest to the source of the river and the latter is closest to the mouth of the river. These are then carried by the river, scraping along the sides of the channel. A PowerPoint version of diagrams and answers. London WC1R 4HQ. registered in England (Company No 02017289) with its registered office at 26 Red Lion registered in England (Company No 02017289) with its registered office at 26 Red Lion Section 2 is the middle course (where it comes down into the lowlands). Completely FREE. If you are offered a cross profile diagram of a valley that appears to be flat with a deep and wide channel of water, then you are probably looking at the lower course of a river, where the gradient is gentle. Meanders support the formation of floodplains through lateral (sideways) erosion. Generally, either erosion or deposition will be a dominant force. A lesson for the topic of Rivers. Ideal for years 7 to 9. Lower course features. River Floods.

Geography / Geomorphic processes and landforms, Geography / Geomorphic processes and landforms / Rivers, The Long Profile of a River: Upper, Middle, Lower Course (MINI). These river diagrams help to explain the geography topic of rivers. River videos. To support EAL students- the resources are supported by structured sentences and key vocabulary. Previously taught in a 1hr lesson. I then get creative to consolidate the learning. Interlocking spurs - where the river winds between ridges. This worksheet is also provided as a PDF. Why not set this as pre-learning so that students can start a lesson from a position of confidence? Tes Global Ltd is Ideal for years 7 to 9. There are particular river features which we can expect to find in each of these sections. Created: Jun 18, 2018| Updated: Aug 2, 2020. These are particles that do not dissolve, but they are easily carried along by the water. This process means that particles get smaller as they travel downstream. Are you looking for high-quality GCSE Geography resources? There are two ways in which you might be asked to identify a river during your examination, they are long profile and cross profile. This is where rocks that have already been eroded hit each other and become smaller. Geography / Geomorphic processes and landforms, Geography / Geomorphic processes and landforms / Rivers. Teacher PowerPoint with diagrams and answer key provided directly onto the slides or in notes section of each slide. Content: This resources describes and explains the formation of flood plains and river deltas. Edexcel GCSE Geography To support students who benefit from short, structured activities. Solution also occurs in rivers. In the upper stage, the river is close to its source and high above its base level (the lowest point the river can erode to 1).In the lower stage the river is far away from its source, close to the mouth and not far above its base level. Section 3 is the lower course (where it is at its widest and most powerful and enters the sea). These are supported by diagrams and follow-up questions. The Lower Course: The last part of a river near its mouth is called the lower course. A River’s Course. Before abrasion can take place, hydraulic action has an important role to play. A word document worksheet that includes step by step descriptions of how the landforms are created.

Includes application through the consideration of planning on flood plains (zonation). OCR GCSE Geography, AQA A Level Geography

Section 1 is the upper course (think high up in the mountains). As this happens more, they lose their jagged edges and become rounded, like pebbles. They are usually still small enough to bounce along the river bed because of the force of the water. This website and its content is subject to our Terms and River Facts. Upper course of river Middle course of river Lower course of river Source - the point at which the river starts. Most rivers have upper, middle and lower courses. Traction involves heavier particles than the ones that we can see in saltation. If you take a look at a cross profile diagram of a river, then it is easy to see that rivers widen at certain points. London WC1R 4HQ. The current is also very slow. Locating the world's famous volcanoes - KS2, Identifying the key features of mountains, Volcanoes and other Natural Disasters - Presentation. NB: When answering questions on River features, always remember to use the F.E.E.D. The course a river takes is split into three stages, the upper, middle and lower stage. Tes Global Ltd is River Severn | River Thames. Conditions. Some features expected in this section of the river are V- shaped valleys, interlocking spurs, a river bed with large rocks and stones,gorges, fast flowing rapids and waterfalls. We call this process deposition, where eroded materials are dropped by the river. Typically, a river valley can be divided into three sections; the upper course, the middle course and the lower course.
