The idea that sedimentary rocks are deposited in horizontal layers unless disturbed by forces within the earth can best be explained by which of stenos principles

B. principle of horizontality

Explanation:

The principle of the horizontality states that the rocks of the sedimentary rock are under the effect of gravity. And it's a relative dating technique. And Was first proposed by the geologist danish pioneer Nicholas steno. As the steno law states that these sedimentary layers are deposited Purley in horizontal strata.

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.
