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 roughly parallel streams cutting draws down the side of a ridge. Contour lines on a map depict a spur with the U or V pointing away from high ground.
In this regard, what is a spur in 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.
Likewise, what is the difference between Valley and spur? Arete is a narrow ridge and a Spur is a smaller ridge branching off a summit or a main ridge. A valley can be “V” or “U” shaped and often can be seen as a “negative” to a ridge. On a map, valleys are represented by the same contour shape as ridges with the difference being the the wide openings are at lower elevation.
Similarly, it is asked, what is a draw in land navigation?
A draw (US) or re-entrant (international) is a terrain feature formed by two parallel ridges or spurs with low ground in between them. The area of low ground itself is the draw, and it is defined by the spurs surrounding it.
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. Terrain features can be learned using the fist or hand to show what each would look like on the ground. Hill-a point or small area of high ground.

How are spurs formed?
Interlocking spurs are formed as either a river or stream cuts its valley into local bedrock. As it entrenches its valley, it preferentially follows and erodes zones of weaknesses within the bedrock that typically consist of intersecting sets of joints.

What is the process of a meander?
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 are channels formed?
Natural channels are formed by fluvial process and are found across the Earth. These are mostly formed by flowing water from the hydrological cycle, though can also be formed by other fluids such as flowing lava can form lava channels.
How does a waterfall form?
Often, waterfalls form as streams flow from soft rock to hard rock. This happens both laterally (as a stream flows across the earth) and vertically (as the stream drops in a waterfall). In both cases, the soft rock erodes, leaving a hard ledge over which the stream falls.

What is a fill on a map?

How do you identify features on a map?
Physical maps show the physical features of a place, which can be identified using the symbols shown in the map’s key or legend. Topographic maps use contour lines to show elevation change. Globes show the world as it is, as a sphere.
What are the three types of lines used on a topographic map?
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 does a Depression look like on a topographic map?
