A spur is a lateral ridge or tongue of land descending from a hill, mountain or main crest of a ridge It can also be defined as another hill or mountain range which projects in a lateral direction from a main hill or mountain range
How can you tell if a map is a spur?
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 a spur 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 a gentle slope in geography?
A gentle slope or curve is not steep or severe
What does bone spur feel like?
Symptoms of Bone Spurs Pain in the affected joint Pain or stiffness when you try to bend or move the affected joint Weakness, numbness, or tingling in your arms or legs if the bone spur presses on nerves in your spine Muscle spasms, cramps, or weakness
What are the four stages of osteoarthritis?
The four stages of osteoarthritis are: Stage 1 – Minor Minor wear-and-tear in the joints Little to no pain in the affected area Stage 2 – Mild More noticeable bone spurs Stage 3 – Moderate Cartilage in the affected area begins to erode Stage 4 – Severe The patient is in a lot of pain
What is needed for a waterfall to form?
Waterfalls often form in the upper stages of a river where it flows over different bands of rock It erodes soft rock more quickly than hard rock and this may lead to the creation of a waterfall The soft rock erodes more quickly, undercutting the hard rock A steep-sided gorge is formed as the waterfall retreats
What are the 3 types of contour lines?
There are 3 kinds of contour lines you’ll see on a map: intermediate, index, and supplementary Index lines are the thickest contour lines and are usually labeled with a number at one point along the line Intermediate lines are the thinner, more common, lines between the index lines
What is sideways erosion called?
A meander is a winding curve or bend in a river Meanders are the result of both erosional and depositional processes They are typical of the middle and lower course of a river This is because vertical erosion is replaced by a sideways form of erosion called LATERAL erosion, plus deposition within the floodplain
How far apart are contour lines on a map?
A contour is a line drawn on a map that joins points of equal height above sea level For 1:25 000 scale maps the interval between contours is usually 5 metres, although in mountainous regions it may be 10 metres
What is the difference between a spur and a draw?
Draw — Sometimes called a “re-entrant,” a draw is a small valley As with a valley, the Vs and Us of a draw’s contour lines point to higher ground Spur — A spur is sloping high ground, often extending out from a ridge As with a ridge, the Vs and Us of a spur’s contour lines point to lower ground
What does a reentrant look like on a map?
A reentrant appears on the map as a U or V shape in the contour lines, pointing back into a hillside rather than sticking out of the hill (as would a spur) So a reentrant is a small valley, the center of which would collect water and funnel it downhill (if it were raining hard)
What are cut off interlocking spurs called?
U-shaped valleys ending with a waterfall at the cliff-face are called hanging valleys When a river erodes the landscape, ridges of land form in its upper course which jut into the river These are called interlocking spurs A glacier cuts through these ridges leaving behind truncated spurs 3
What does the PO symbol represent on OS maps?
Ordnance Survey Abbreviations P Paling, Passage, Pavement, Pillar, Plug, Pool, Pump PO Post Office (large scales) POD Detail Point (Point of Detail) Pol ho Police House Pol Sta Police Station
What does a concave slope look like on a map?
Concave: Contour lines showing a concave slope on a map will be closely spaced at the top of the terrain feature and widely spaced at the bottom Bushwalkers going up the slope will find the terrain increasingly steep and challenging
What is the difference between a spur and a valley?
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
What is a spur in a river?
A spur is a structure or enbankment projected into a stream fron the bank at some angle and for a short distance to deflect flowing water away from critical zones, to prêvent erosion of the bank, and to estab- lish
How is a spur formed?
Spurs and Interlocking Spurs 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 Imagine two gently sloping hillsides forming the sides of a small valley
Do you need surgery for a bone spur?
Surgery is one option to alleviate pain associated with a heel spur But this is not the first line of defense A doctor will first recommend other treatment methods to resolve pain Most people who have a heel spur don’t need surgery
What is a spur ridge?

What does a spur look like?
Heel spurs may be pointy, hooked, or shelf-like The outgrowth of a heel spur extends from the underneath of the heel towards the arch (the middle of the foot) This area of the foot is called the plantar fascia When seen on an X-ray, a heel spur may be up to half an inch long
What is spur in map reading?
A gorge is represented by very closely-spaced contour lines on a map with the innermost contour showing small gap between its two sides 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 are the 5 major terrain features?
The five major terrain features are: Hill, Ridge, Valley, Saddle, and Depression The three minor terrain features are: Draw, Spur and Cliff
What does a Depression look like on a topographic map?
Contour lines that show a depression, crater, or sinkhole on a map are represented by dashed lines (hachure marks) on the inside of a contour line The elevation of the first depression contour is the same as the nearest regular contour line
