Question

The early hypothesis of _______ was based on observations that suggested continents were once joined together. Later, the theory of _______ explained why large pieces of Earth's surface move around and how many of Earth's features form.
A.
plate tectonics; continental drift
B.
gravitational force; continental drift
C.
plate tectonics; gravitational force
D.
continental drift; plate tectonics

Answer 1

The correct answer is D. **continental drift; plate tectonics**.

The early hypothesis of continental drift, proposed by Alfred Wegener, suggested that continents were once joined together and have since drifted apart. The theory of plate tectonics later provided a comprehensive explanation for the movement of the Earth's lithosphere and the formation of various geological features.
