3. What impact does topography have on production and life?

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 and improve the moisture conditions there.

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.
