Surface Features - SS3 Geography Lesson Note

Sinkholes: These are surface depressions that vary in size and can be shallow or deep. Sinkholes can pose challenges for construction and land use planning.

Karst Valleys: Some karst regions exhibit elongated, U-shaped valleys formed by the collapse of cave roofs, creating surface troughs with steep sides.

Tower Karst: In some areas, particularly in China, tower karst formations are prominent, characterized by tall limestone pillars or towers that rise from the landscape.

Poljes: Large, flat-bottomed depressions known as poljes can develop in karst regions and often serve as temporary storage for water during heavy rainfall.

Caves and Caverns: Karst regions are known for their extensive underground cave systems, with impressive stalactites and stalagmites, making them popular for exploration and tourism.
