Question

Briefly explain how the following forms of evidence are used to support the theory of plate tectonics:

a. Paleomagnetism b. Ocean Drilling

Answer 1

Explanation:

Paleomagnetism. Paleomagnetism is the study of the earth's past magnetic field. ... So, paleomagnetism can really be thought of as the study of an ancient magnet field. Some of the strongest evidence in support of the theory of plate tectonics comes from studying the magnetic fields surrounding oceanic ridges.

The Deep Sea Drilling Project (DSDP) was an ocean drilling project designed to analyze the ocean floor. ... This showed that new oceanic crust was being formed along the plate boundary and then spreading out laterally, providing evidence to support the theory of seafloor spreading and plate tectonics.
