Geography Form Five Revision Questions Theories of Landforms Formation explain how various natural features on Earth’s surface—such as mountains, valleys, plains, and plateaus—are created and modified over time. These theories are based on geological, climatic, and geomorphic processes. The main theories include:
Tectonic Forces: Earth’s Powerlifting Moves
Imagine the Earth’s surface as a giant puzzle made of plates that are constantly moving—sometimes colliding, sometimes drifting apart. These movements create some of the most dramatic landforms we see today.
Mountains & Valleys (Plate Tectonics Theory) – When two plates collide, they push land upward, forming mighty mountain ranges like the Himalayas. On the flip side, when plates pull apart, they create deep valleys and rift zones, like the East African Rift Valley.
Earthquakes & Faults (Continental Drift) – Ever heard of the San Andreas Fault in California? That’s where two plates grind past each other, causing earthquakes and shaping the land in real time.
Isostasy: Earth’s Balancing Act – When heavy glaciers press down on the land, it sinks slightly. When they melt, the land rises back up. It’s like nature’s version of a memory foam mattress!
