the top of the elevated hill, slope, or mountain.
Contour lines that form a circle indicate elevation.
Depressions
Contour maps are useful because it provides a relatively accurate measurement of altitude. Contour maps utilize contour lines to indicate different elevations. They identify the vertical and horizontal dimension of land surfaces or terrains. Contour maps are important because they accurately represent land form height as well as the watershed presence. Farmers can use this to plan how their fields will be plowed and planted. Hikers use them to plan hikes.
On a topographic map, you can identify a hill by examining the contour lines. Contour lines that form closed loops are an indication of a hill or a mountain. The closer the contour lines are together, the steeper the slope of the hill.
The rule of "V" on a topographic map refers to the shape created by contour lines when they converge or come together. When contour lines form a "V" shape, it indicates a valley or a depression in the terrain. The point of the "V" always points upstream or towards higher elevation.
A 'great circle' is any circle on the surface of a sphere that has its center at the center of the sphere. The equator is the only parallel of latitude that's a great circle. Every meridian of constant longitude is a semi-circle, and together with the one directly opposite it, they form a great circle. The shortest distance between two points on a sphere is the piece of the great circle through them.
Isobars are lines that join areas of the same pressure. Low pressure areas are circular, so the isobar lines will form a loop and join ends. The varying pressures can now be seen as concentric rings, with the lowest pressure at the center of the circle.
Hill,Slope or Mountain
A hill or a crater.
Hachure lines are a form of representation for showing the contours on a map. They point towards the steepest part of the slope. Hachure lines are an old form of showing relief, and less useful, scientifically, than contour lines.

The lines on a map that form a grid system are called latitude and longitude lines. Latitude lines run horizontally and measure distance north and south of the equator, while longitude lines run vertically and measure distance east and west of the Prime Meridian.

It means a small difference in elevation, let's say, for an example, a river.
The closer the lines are together - the steeper the slope.
They are straight lines, part s of which form chords of the circle.
Hachures are marks that can be found on the contour lines that form a depression on a topographical map.
