Q. These are the two theories that refer to the separation of the same terrain in the world in ancient times.
a. Plate Tectonics and Seafloor Spreading
b. Plate Tectonics and Subduction Theory
c. Continental Rift and Plate Tectonics
d. Continental Drift and Plate Tectonics
Answers
Answer:
Discover how heat from Earth's core creates convection currents that cause crustal plates to shift The land on Earth is constantly moving. Over millions of years, the continents broke apart from a single landmass called Pangea and moved to their present positions
The theory of plate tectonics provides an example of the evolution of scientific thought. The first two sections of the chapter reveal the basic observations that were used to make predictions on the geologic processes that shaped the face of Earth.
Seafloor spreading disproves an early part of the theory of continental drift. Supporters of continental drift originally theorized that the continents moved (drifted) through unmoving oceans. Seafloor spreading proves that the ocean itself is a site of tectonic activity.
