Description

"Interpretation of Topographic Maps" Earth and Maps PPT Courseware 3

Self-study outline: Self-study books P24-P26

1. What is altitude and relative height? What's the difference between them?

2. Definition of contour lines, and read pictures to find out the characteristics of contour lines.

3. How many types of parts are there in mountains? What are the differences in their contour shapes?

What is the difference between the highest and lowest in the world?

Mount Everest, with an altitude of 8,844 meters, is the highest peak in China and the highest peak in the world.

The Dead Sea, located on the border between Jordan and Palestine, is the lowest lake in the world. With an altitude of about 400 meters below sea level, it is the lowest point on earth.

Contour features:

1. It is a closed curve.

2. The altitudes on the same contour line are the same.

3. On the same contour topographic map, the contour distances are equal.

4. The denser the contour lines, the steeper the slope; the sparser the contour lines, the gentler the slope.

Self-study outline:

1. What is a layered color topographic map?

2. How many types of terrain are there? What are the characteristics of each?

3. What is a topographic profile? What does it do?

2. Layered color topographic map:

On a contour topographic map, different colors are used to show the ups and downs of the terrain. Such a map is a layered color topographic map.

The legend "high land and deep sea" is often used to represent changes in altitude.

Think: How many types of landforms are there?

Five basic terrain types

According to the characteristics of the surface, the terrain is generally divided into five categories: plateau, mountain, basin, hill, and plain.

summary:

1. Altitude: the vertical distance of a location above sea level

Relative height: the vertical distance between one location and another location

2. Characteristics of contour lines: dense contour lines and steep slope; sparse contour lines and gentle slope.

3. Different parts of the mountain: top, valley, ridge, saddle, cliff

4. Terrain types: plains, plateaus, mountains, hills, basins

5. Layered color topographic maps and topographic profiles

practise:

1. Determine the names of each part of the mountain represented by the following contour map.

2. Xiao Ming and his classmates went for a spring outing to the mountains. Could you please help them analyze which route is best for going up the mountain? Why?

Contour lines are dense and the slope is steep; contour lines are sparse and the slope is gentle.
