Answer:The principle is called the Law of Superposition.
Explanation:a major principle of stratigraphy stating that within a sequence of layers of sedimentary rock, the oldest layer is at the base and that the layers are progressively younger with ascending order in the sequence.
The Earth's surface is covered by a series of crustal plates.The ocean floors are continually moving, spreading from the center, sinking at the edges, and being regenerated.Convection currents beneath the plates move the crustal plates in different directions.The source of heat driving the convection currents is radioactivity deep in the Earths mantle.
The correct answer is A. Bighorn sheep

Igneous rock is formed when magma cools down. The igneous rock is then pushed into the Earth which is the process of tectonic activity. Some, but not all of the igneous rocks will be pushed into the mantle of the Earth. The ones that are pushed to the mantle will be shown to great temperatures, which will cause them to melt and reform as magma. For the rocks that are not pushed into the mantle, they are broken down into sediment by weathering.
Sedimentary rocks are when the layers of sediment are compacted and then transformed into sedimentary rocks. <span />
