What is spur geography?
In geography, a spur is a piece of land jutting into a river or stream or a ridge descending from mountains into a valley. Spurs are formed from erosion over time and frequently divide tributaries or valleys.
What is a spur in a river?
Spurs, and interlocking spurs, are features found in the upper reaches of river valleys. They are erosional features, meaning that they are formed by water flowing over the land and eroding it as it moves. This means that if you look along the valley the spurs seem to join together, or interlock.
How is a spur formed in geography?
A spur is formed between two river valleys. In the case of a river valley, the greatest height is to the outer side and the land sinks down towards the inner side, where the riverbed is. In the case of a spur, the greatest height is to the inner side and the land sinks down towards the outer side of the spur.
What is spur in surveying?
Spur. A tongue of land, projecting from higher ground into the lower is called a spur. It is also represented by V- shaped contours but in the reverse manner.
What is a spur ridge?
A small ridge which extends finger-like from a main ridge.
What is the shape of a spur?
Spur gears are a cylindrical shaped toothed component used in industrial equipment to transfer mechanical motion as well as control speed, power, and torque.
What are spurs in irrigation?
Spurs are the structures constructed on the river bank normal to the dominant flow direction or at an angle pointing upstream or downstream. A spur consists of a shank and a nose or head.
What is valley and spur?
Identifying features The closer together the contour lines, the steeper the slope of the hill. A spur is a ‘V’-shaped hill that juts out. A simple way to tell a valley from a spur when looking at contour lines is to remember that if the ‘V’ points uphill it’s a valley, if it points downhill it’s a spur.
Where are interlocking spurs found in a river?
upper course
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.
What is the difference between spurs and valley?
A simple way to tell a valley from a spur when looking at contour lines is to remember that if the ‘V’ points uphill it’s a valley, if it points downhill it’s a spur. A spur is often formed by two rough parallel streams, which cut draws down the side of a ridge.
What is a spur on a contour map?
What is spur topography?
Spur (topography) A spur is a lateral ridge or tongue of land descending from a hill, mountain or main crest of a ridge.
What is a spur terrain?
Spur (Minor Terrain Feature) Spur. A spur is a short, continuous sloping line of higher ground, normally jutting out from the side of a ridge. A spur is often formed by two rough parallel streams, which cut draws down the side of a ridge. The ground sloped down in three directions and up in one direction.
How did the geography spur industrialization in the northeast?
One way in which geography spurred industrialization in the Northeast was the areas close proximity to water, which was highly important for factories that needed cooling and waste removal.
