What do you call a topographic feature that is a dip or low point?

What do you call a topographic feature that is a dip or low point?

A dip slope is a topographic (geomorphic) surface which slopes in the same direction, and often by the same amount, as the true dip or apparent dip of the underlying strata. The frontslopes of such ridges consist of either an escarpment, a steep slope, or perhaps even a line of cliffs.

What do you call a topographic feature that is a dip or low point between two areas of higher ground?

Saddle
Saddle: A saddle is a dip or low point between two areas of higher ground.

What is a saddle topography?

Topography. A saddle is the lowest area between two highlands (prominences or peaks) which has two wings which span the divide (the line between the two prominences) by crossing the divide at an angle, and, so is concurrently the local highpoint of the land surface which falls off in the lower direction.

What does depression look like on a topographic map?

A depression is represented by a series of concentric closed contours with the inner contours having lower elevation than their outer surrounding. There are small tick marks or hachures on these contour lines pointing towards lower elevation.

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.

What is the difference between a saddle and a col?

Saddle & Col A saddle is literally that shape in the mountain that is high & broad at each end and narrower & lower in the middle. The saddle typically connects two mountains (or peaks). A Col is similar to a saddle but it always connects two peaks. Sometimes a Col is also understood as a saddle at high altitude.

What is saddle point?

1 : a point on a curved surface at which the curvatures in two mutually perpendicular planes are of opposite signs — compare anticlastic. 2 : a value of a function of two variables which is a maximum with respect to one and a minimum with respect to the other.

What is the difference between a hill and a depression on a topographic map?

When contour lines are closer together on a map, they indicate a steep slope. Think of contour lines as the distance between each incline. The closer together the inclines, the steeper the hill. On the other hand, the farther apart lines tend to indicate a depression in the landscape.

What do closely spaced contour lines on a topographic map mean?

Closely-spaced contour lines indicate a steep slope, because the elevation changes quickly in a small area. Contour lines that seem to touch indicate a very steep rise, like a cliff or canyon wall. Broadly spaced contour lines indicate a shallow slope. A portion of a USGS topographic map of Stowe, Vermont.

What do the colors on a topographic map mean?

On a large scale geologic map, colors represent geological provinces. Topographic maps are 2-dimensional representations of the 3-dimensional surface features of an area. Topographic maps have contour lines that connect points of identical elevation above sea level. Contour lines run next to each other.

How are rock units identified on a topographic map?

Rock units are color-coded and identified in a key. In the map of Yosemite ( Figure below ), volcanic rocks are brown, the Tuolumne Intrusive Suite is peach, and the metamorphosed sedimentary rocks are green. Structural features, such as folds and faults, are also shown on a geologic map.

How are topographic maps used in oceanography?

People use topographic maps to locate surface features in a given area, to find their way through a particular area, and to determine the direction of water flow in a given area. Oceanographers use bathymetric maps to depict the features beneath a body of water.
