Topic explanation

Standard explanation

Earth receives and loses energy unevenly with latitude, creating a general energy surplus at low latitudes and energy deficit at high latitudes.

Key points

• Net radiation = absorbed solar − outgoing infrared
• Heat Redistribution: Near the equator, sunlight arrives more directly on average. The same solar energy is concentrated
• Formula / Key Relation: Conceptually: Net radiation = absorbed solar − outgoing infrared Low latitudes → often net sur
• Unequal solar heating creates a global need for heat transport.
• Earth receives and loses energy unevenly with latitude, creating a general energy surplus at low latitudes and **ene
