Earth's dynamic helps us perceive the different situations and earth's movements, for example, it's an association with force, the occurrence of an earthquake, natural phenomena like a volcano, focus, epicentre etc. It additionally teaches ideas associated with ocean waves, river, ice, and wind which Chapter 3 of Class 7 Geography titled 'Our Changing Earth' teaches by helping students understand various earth movements by explaining in detail why all of these occur by taking a look into understanding both the natural and man-made causes to it.

We will talk about the forces which act in the interior of the earth called the Endogenic forces. The forces in action on the earth's surface are called the Exogenic forces and how Endogenic forces sometimes produce sudden movements that cause earthquakes and volcanoes and produce slow movements that result in faulting and folding of the landmass.
