What is the theory that Earths surface is composed of several rock plates that fit together like the pieces of a puzzle?
A: plate tectonics
B: metamorphism
C: divergent plate boundary
D: geological shift
A: plate tectonics
The theory that Earth's surface is composed of several rock plates that fit together like the pieces of a puzzle is known as plate tectonics (option A). This theory describes how the Earth's lithosphere is divided into several rigid plates that move due to the underlying convective currents in the mantle. These plates interact along their boundaries, leading to various geological phenomena such as earthquakes, volcanic activity, mountain formation, and the creation of oceanic trenches.
The theory that Earth's surface is composed of several rock plates that fit together like the pieces of a puzzle is called plate tectonics. Plate tectonics is the scientific theory that explains how the Earth's lithosphere (the outermost layer of the Earth, consisting of the crust and upper mantle) is divided into a number of large and small plates that move and interact with each other.
To understand plate tectonics, scientists use a combination of evidence from various sources, including seafloor spreading, volcanic activity, earthquakes, and the distribution of fossils and rocks. The theory suggests that these lithospheric plates are in constant motion, driven by the underlying convective currents in the Earth's mantle.
