How will you distinguish between a valley line and a ridge line?
A valley is an elongated depression in the landscape that is formed by the action of water (V-shaped) or carved out by glaciers (U-shaped). Two ridge lines run north-south connecting peaks on either side of the valley. Steep gullies and spurs run from ridge lines to valley bottom.
What is a valley on a topographic map?
Valleys are elongated low-lying depressions usually with a river flowing through it. You know that you’re looking at a valley bottom when contour lines are V or U-shaped.
What is a ridge in topography?
A ridge or a mountain ridge is a geographical feature consisting of a chain of mountains or hills that form a continuous elevated crest for some distance. The sides of the ridge slope away from narrow top on either side. Ridges are usually termed hills or mountains as well, depending on size.
Which shape line indicates presence of a ridge?
Which shaped lines indicate the presence of a ridge? Explanation: The contour line with U-shape, which has convexity towards a lower ground shows the presence of a ridge.
How do you identify a ridge on a topographic map?
A ridge is a long narrow section of higher ground with lower ground sloping away. On a topo map look for contour lines that form a “U” shape. The bottom of the U will be pointing downhill. Ridges may connect several hilltops or they may slope gradually down in one direction.
What is a spur ridge?
A small ridge which extends finger-like from a main ridge.
What are the types of ridge?
Friction ridge patterns are grouped into three distinct types—loops, whorls, and arches—each with unique variations, depending on the shape and relationship of the ridges: Loops – prints that recurve back on themselves to form a loop shape.
What’s 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.
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.
What are major terrain features?
Major Terrain Features. Hill – A hill is an area of high ground.
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.
