Part One Content: New Course Knowledge

1. Introduction of new courses

Xiao Ming competed with TOM to climb Mount Taishan. The clever TOM used a map and climbed to the top of the mountain quickly. Does anyone know what map it is?

They conducted on-site measurements of Mount Tai from the foot of the mountain to the top of the mountain. The result was that the height was less than 1,300 meters, but the data said its altitude was 1,500 meters high. What the hell is going on?

2. Learning new courses

(1) Altitude and relative altitude

1. What is altitude?

2. What is relative height?

Altitude measuring tool

(1) The top of XX Mountain is ____ meters above sea level, and the foot of the mountain is ____ meters above sea level. The relative height between the top of the mountain and the foot of the mountain is about _______ meters.

(2) The altitude of the world's highest peak, Mount Everest, is about 8844 meters, and the altitude of the Dead Sea, the lowest depression on land in the world, is about 415 meters. What is the relative height of the two?

(2) Contour topographic map

1. Textbook P32-33 content, complete the following content:

(1)What are contour lines?

(2) Are the values ​​marked on the contour lines altitude or relative height?

(3) What is a contour topographic map?

2. Read the picture on the right and complete:

(1) On the same contour line, are the altitudes equal?

(2) How many meters is the contour distance (height difference between two adjacent contour lines) in the picture? Are the contour distances equal on the same contour map?

(3) What does the denser contour lines mean? What does the sparser contour lines mean?

Part 2 content: Class summary

3. Conclusion summary

Please use the contour topographic map of XX Mountain you just drew and combine it with the model you made to talk about the names of different parts of the mountain and the characteristics of the contour lines.

Contour lines are closed, high in the center and low around
