Question

The theory of plate tectonics states that:

A
Earth's crust and upper mantle are broken into sections called plates that move on a thick, plastic-like layer of the mantle
B
Earth's crust and upper mantle are broken into sections called plates that move on a thick, plastic-like layer of the asthenosphere
C
Earth's crust and upper mantle are broken into sections called plates that move on a thin, liquid layer of magma
D
Earth's crust and upper mantle are broken into cracks called plates that move on a thick, plastic-like layer of the asthenosphere

Answer 1

B) Earth's crust and upper mantle are broken into sections called plates that move on a thick, plastic-like layer of the asthenosphere.

Step-by-step explanation:

The theory of plate tectonics is a scientific theory that explains the large-scale movements of the Earth's solid outer layer, the lithosphere. It states that the Earth's lithosphere is broken into sections called plates that move on a thick, plastic-like layer of the mantle called the asthenosphere. These plates move due to the convective movements of hot, molten rock in the mantle. The movements of these plates can cause earthquakes, volcanic eruptions, and the creation of new oceanic and continental crust. The theory of plate tectonics has helped us to understand many geological processes and has been confirmed by a large body of scientific evidence.
