Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which theory states that the Earth’s lithosphere is broken into plates that move by convection currents in the mantle?
A
Continental Drift Theory
B
Theory of Plate Tectonics
C
Big Bang Theory
D
Theory of Evolution
Explanation: 

Detailed explanation-1: -The theory of plate tectonics revolutionized the earth sciences by explaining how the movement of geologic plates causes mountain building, volcanoes, and earthquakes.

Detailed explanation-2: -Tectonic Plates The system of ideas behind plate tectonics theory suggests that Earth’s outer shell (lithosphere) is divided into several plates that glide over the Earth’s rocky inner layer above the soft core (mantle).

Detailed explanation-3: -Plate tectonics is the scientific theory explaining the movement of the earth’s crust. It is widely accepted by scientists today. Recall that both continental landmasses and the ocean floor are part of the earth’s crust, and that the crust is broken into individual pieces called tectonic plates (Fig.

Detailed explanation-4: -This concept is commonly known as the theory of plate tectonics. This theory describes how the Earth’s lithosphere is broken up into about a dozen plates or so which slide by, collide with or move away from each other as new ocean floor is created.

Detailed explanation-5: -The theory of plate tectonics (tek TAHN iks) states that pieces of Earth’s lithosphere are in slow, constant motion, driven by convection currents in the mantle. The theory of plate tectonics explains the formation, movement, and subduc-tion of Earth’s plates.
