the study of elevations of land; it includes hills, mountains, plains, plateaus and valleys

Elevation is

Lines that are close together show that the slope of the land is ________________.

The place where a stream starts on a contour map is called the _____________.

All points on a contour line are at the same elevation.

height above sea level

Topographic/contour maps

Gently sloping land is shown by lines that are _______________.

The place where a stream empties into a lake or an ocean is called the ______________

Contour lines never cross.

maps that use lines to represent differences in elevation

This is a word that is used to describe how quickly elevation rises (or how steep the land is)

This shows how much the elevation changes from one contour line to the next.

Contour lines seem to form arrows at a stream that point (toward, away) from the direction of the flow of the water.

Contour intervals always increase by 10 meters.

These lines on a map are used to show elevation. All points on a line are at the same elevation.

This is the difference in elevation between contour lines

Hachmarks on contour lines are used to show _____________________.

A triangle with a number next to it is sometimes used on a map to show this.

Contour maps are used to show boundaries between countries.

The difference in elevation between contour lines is known as the contour _____________.

This is the difference between the highest and lowest parts of an area.

Many contour maps start at an elevation of 0 feet or meters. This is known as __________________.

Depression contours (with hachured lines) are used on a map to show this.

Contour maps would be useful to hikers.
