According to Alfred Wegener, all the major continents formed one giant supercontinent, called Pangaea. About 200 million years ago, the supercontinent Pangaea began to rift.
The amount of insolation received varies from latitude to latitude. The Regions within the equator and 40° N and S latitudes are energy surplus regions because they receive abundant sunlight and hence more heat will be gained than lost.The Regions beyond 40° N and S latitudes are energy deficit regions because they lose more heat than that gained from sunlight.
