Exogenic processes are those driven by exogenic forces that primarily derive their energy from solar radiation. For instance, soil erosion is caused by the force of wind acting on bare ground. ... Endogenic processes are those that get their energy from endogenic forces originating deep within the Earth.

Convection ek heat transfer ka process hota hai jiska main reason hota hai kisi fluid( gas/liquid) ka motion me hona aur isme heat enery , heat source se door jati hai. Ab plate tectonics k case me dekhein to earth k interior me jo elements hote hain unke decay ( sadne ) se heat generate hoti hai jisse magma ( liquid rock) banta hai.

Ab convectional currents is heated magma ko earth k interior se surface k pas lati hai jahan tectonic plate ki boundaries hoti hai... aur isi current se surface pe plates ek dusre se alag hote jate hain.
