What is a interlocking spur in geography?
Interlocking spurs The river cuts down into the valley. If there are areas of hard rock which are harder to erode, the river will bend around it. This creates interlocking spurs of land which link together like the teeth of a zip.
What are the characteristics of interlocking spurs?
Interlocking Spurs convex slopes. project from alternate sides of the valley. separated by a narrow valley floor which is mainly taken up by the river channel. sometimes covered in woodland.
What course are interlocking spurs in?
Upper course river
Upper course river features include steep-sided V-shaped valleys, interlocking spurs, rapids, waterfalls and gorges. Middle course river features include wider, shallower valleys, meanders, and oxbow lakes.
Where can interlocking spurs be found?
Interlocking spurs are projections of high land that alternate from either side of a V-shaped valley. They are formed by fluvial erosion and are found in the upper course of a river where rocks are hard. Formed when the river is small and has less erosive power.
What is River Valley and spur?
An interlocking spur, also known as an overlapping spur, is one of any number of projecting ridges that extend alternately from the opposite sides of the wall of a young, V-shaped valley down which a river with a winding course flows.
What are the 3 river courses?
The Lower or Deltaic Course.
- The Upper Course: In the mountainous course, a river passes through a steep slope.
- The Middle Course: As a river leaves the hilly area and enters into a plain, its middle course starts.
- The Lower Course: The last part of a river near its mouth is called the lower course.
Where are truncated Spurs found?
Truncated spurs can be found within mountain ranges, along the walls of river valleys, or along coastlines.
What are rapids in geography?
Rapids are areas of shallow, fast-flowing water in a stream. Rapids tend to form in younger streams, with water flow that is straighter and faster than in older streams. Softer rocks in the streambed erode, or wear away, faster than harder rocks.
What does a spur look like in geography?
spur mountain wicklow geography You can spot a spur on the map quite easily – it looks like a long, narrow tongue of contour lines, dropping away from a mountain top or a ridge. Usually its sides will be quite steep, but its top will slope gently downwards.
What is the difference between a spur and a ridge?
Ridge (Also: Arete or Spur) – A continuous elevated terrain with sloping sides. In the map represented by “U” or “V” shaped contour lines where the higher ground is in the wide opening. Arete is a narrow ridge and a Spur is a smaller ridge branching off a summit or a main ridge.
