How Nature gives the planet, its fascinating features

Three types of energy - heat from the Earth's interior, heat from the Sun, and the force of gravity - give the planet its fascinating features.

The perpetual cycle of change which has created the face of the Earth, with all its rugged and fascinating variety, usually happens too slowly to be noticed. But occasionally it is rapid and violent. Volcanoes disgorge molten lava, earthquakes rips open the landscape, landslides carry away whole mountainsides. Then human beings become aware of the awesome forces that are shaping their planet. 

These forces are fuelled by three powerful sources of energy - heat from within the Earth, heat from the Sun, and the force of gravity. Every landform in the world has been shaped by these three energy sources. 

Everything you need to know how the natural forces shaped our planet in a gradual manner to its today's fascinating shape and features.
