convection currents
"Plate tectonics" is a fancy word for "Continental Drift". In both theories the continents move.
simple....the answer is mantle.(: Glad to help!
The sun is the major source of energy for the food chain through a process called photosynthesis. Plants, algae, and some bacteria capture sunlight to convert it into chemical energy that is then passed on to consumers in the food chain.
unsupported climatic evidence
sunlight
The main problem with Wegners theory of continental drift was that at the time he proposed it he had no real proof.
The major steps are 1) the east African rift 2) east Africa 3) west Africa
During the Devonian Age/Period of the Paleozoic Era, the two major landmasses Gondwana and Eurasia pushed together with continental drift to form the Appalachians.
The sun is the major external source of energy.
Wegner was the man who established the theory of "continental drift" in 1912
the major source is sun

yes them sun is a major source of energy because the sun is used 4many things
The sun is the major source of energy in the desert as well as most other biomes on earth.
solar energy
