Explain why two soils forming in the same climate under similar vegetation might still end up with quite different horizons and other characteristics.

Explained below

Explanation:

Factors affecting soil formation are

ClimateParent Material TopographyBiological FactorsTime

so the soil Forming under similar vegetation might end up with quite different horizons and other characteristics because with different parent bedrock and  biological factors they may end up with different characteristic.

Also time taken by them during soil formation might be different so it could also causes different horizons and characteristics.

Ibelieve that would be a

Mantle convection is the process that drives plate tectonics. the theory of plate tectonics states that the crust is divided into plates that float on the semi molten mantle below. the circular motion of the magma as it slowly rises and falls or move though convection cells drags the plates along causing them to move. the heat source in the lamp would represent the earth's core. the core is the source of energy that drives convection in the mantle. the lava represents molten magma under the earth's surface. if the lava lamp had floating pieces they would move as the circular motion of the lava in the lamp as it rises and falls would move them along the surface. these floating pieces would represent pieces of the earth's crust.
