"Topography and Relief" China's Natural Environment PPT Courseware 4

1. Terrain

Give it a try:

1. Read the map and observe which mountain ranges separate the first and second ladders of terrain in my country?

Kunlun Mountains-Qilian Mountains-Hengduan Mountains

2. Which mountains are used as the dividing line between the second and third steps?

Daxinganling—Taihang Mountain—Wushan Mountain—Xuefeng Mountain

1. Topographic Characteristics and Impact

1. Characteristics: It is high in the west and low in the east, forming a three-level ladder.

2. Impact: Please tell us the impact of my country’s topography? (Considering aspects such as precipitation, rivers, transportation, economy, etc.)

The impact of terrain characteristics on my country’s natural environment and economic activities

Question exploration

1. The terrain of my country's mainland is higher in the west and lower in the east, facing the ocean. What impact may this distribution have on climate and river flow?

Impact on climate: my country's terrain is high in the west and low in the east, sloping toward the ocean, which is conducive to the moist airflow from the ocean penetrating into the inland to form precipitation, which is very beneficial to the development of agricultural production in the vast areas of eastern my country.

Impact on the flow direction of rivers: causing my country's major rivers to flow from west to east into the sea.

2. When the river flows from a higher level to a lower level, what will happen to the height difference? What is the use value?

When the river flows from a higher level to a lower level, the river has a large drop.

Sections of rivers with large drops, rapid currents and abundant water energy are suitable for the construction of hydropower stations.

3. Tell us what impact my country’s topography may have on transportation between the east and west?

On the one hand, the large river flowing eastward connects my country's east-west transportation, facilitates economic connections between the coast and the inland, and is conducive to promoting the economic development of coastal areas and the economic development of western regions. On the other hand, the tall mountains at the junction of the stairs have also become a huge obstacle to my country's east-west transportation.

The impact of terrain characteristics on my country’s natural environment and economic activities

Climate: High in the west and low in the east are conducive to the advancement of warm and humid ocean winds inland, causing abundant precipitation in most areas in the east.

Rivers: Most rivers flow eastward; they have large differences and abundant water energy resources. Large hydropower stations can be built at the junction of the stairs.

Transportation: Large rivers are conducive to east-west communication, but tall mountains will hinder transportation.

Economy: The western plateau and mountainous areas are dominated, and the economy is backward; the eastern plains and hills are dominated, and the economy is developed.
