3. Supplementary lines appear as dotted lines, indicating flatter terrain.

What is topographic effect?

Is a desert a topographic feature?

Topographic barriers such as mountains and hills force prevailing winds up and over their slopes. As air rises, it also cools. Cooler air is capable of holding less water vapor than warmer air. As air cools, this water vapor is forced to condense, depositing rain or snow on windward slopes.

How does distance from the sea affect climate?

How does topography affect human life?

These features include vegetation, climate, the local water cycle, and land formations. Geography doesn’t just determine whether humans can live in a certain area or not, it also determines people’s lifestyles, as they adapt to the available food and climate patterns.
