Topography and relief characteristics PPT, part 2: China’s topography overview

1. The terrain is higher in the west and lower in the east.

1. What are the main characteristics of my country’s terrain?

2. How many levels can my country’s terrain be divided into? Approximately how many meters above sea level is the average altitude of each step? What are the boundaries between the first and second steps and the second and third steps?

group discussion

The influence of the terrain of high in the west and low in the east on our country

climate

Conducive to the advancement of moist air flow from the sea to the inland

Bring abundant rainfall to vast areas

river

Running from west to east into the sea

The water flow is fast and the drop is large at the junction of the stairs.

transportation

Advantages: The great east-flowing river connects east-west traffic

Facilitate economic connections between coastal and inland areas

Disadvantages: The high mountain at the junction of the stairs is an obstacle to east-west traffic

2. Complex and diverse terrain

The terrain types are diverse and the mountainous area is vast.

my country is a mountainous country, with mountainous areas accounting for about 1/3 of the country's total area, and mountainous areas (including mountains, hills, and relatively rugged plateaus) accounting for about 2/3 of the country's total area. The plain area accounts for a little more than 1/10.

3. Main terrain areas

1. Main mountain ranges in my country
