"Topography and Relief Characteristics" PPT courseware

Part 1: Thinking by looking at pictures

Picture Viewing: Thinking about the distribution characteristics of Asia’s terrain?

High in the middle and low around;

Mainly plateaus and mountains;

Great difference between high and low

Picture observation: 1. Combined with the terrain profile near 360N, talk about how the altitude changes from point A to point B?

The altitude gradually decreases from A to B→high in the west and low in the east

2. Look at the three distinct levels of color in the picture, and compare it with the altimeter. What are the characteristics of my country's terrain?

China’s terrain features:

The terrain is higher in the west and lower in the east, with a three-step descending distribution.

Topography and relief characteristics PPT, the second part of the content: Problem thinking

Thinking: What impact does my country’s topographic characteristics have on climate, rivers, shipping, and water resources development?

Climate: Conducive to the penetration of moist ocean air into the interior, bringing precipitation

Rivers: Many rivers in our country flow into the ocean from west to east

Shipping: Flows from west to east, connecting east-west transportation and facilitating connections between the coast and the interior.

Water resources: At the junction of the stairs, the river has a large drop and rapid water flow, which contains rich water energy.

1. What are the types of terrain in my country? Do all terrain types have the same proportions?

Terrain characteristics: The terrain is complex and diverse, with vast areas of plateaus and mountains.

2. Are mountainous areas the same as mountains? What's the difference?

Mountainous areas: People collectively refer to plateaus, mountains and hills; proportion: 69% (nearly two-thirds)

Topographic features PPT, the third part: main terrain areas

There are many mountains in our country, and the directions of the mountains show certain regularity.

Northwest-southeast mountain ranges: Altai Mountains, Lesser Khingan Mountains, Qilian Mountains

North-south mountain ranges: Hengduan Mountains, Helan Mountains

Arc Mountains: Himalayas

Find the dividing line between the three ladders?

The dividing line between the first and second steps: Kunlun Mountains-----Qilian Mountains------Hengduan Mountains

The dividing line between the second and third steps: Daxinganling---Taihang Mountain---Wushan---Xuefeng Mountain

(1) Four plateaus

Inner Mongolia Plateau

The terrain is open and broad; grasslands are widespread.

loess plateau

Thousands of ravines and fragments.

Yunnan-Guizhou Plateau

The terrain is rugged and karst landforms are widespread.

Qinghai-Tibet Plateau

Glaciers are widespread and snow peaks are continuous

(2) Four major basins

Tarim Basin

The interior is flat and desert is widespread.

Junggar Basin

There is the Gobi Desert in the interior; there are mountain passes in the west, with slightly more precipitation;

Sichuan Basin

Purple soil

Qaidam Basin

highest altitude
