What does the theory of plate tectonics say about the earth’s surface?

Question

A. The earth is broken into many pieces.

B. The earth is very thick.

C. The earth is mostly covered in water.

D. The earth is one solid piece.

Answer 1

The correct answer is:

A. The earth is broken into many pieces.

The theory of plate tectonics explains that the Earth's lithosphere is divided into several tectonic plates that float on the semi-fluid asthenosphere beneath them. These plates interact with each other, leading to various geological phenomena such as earthquakes, volcanic activity, and the formation of mountains.

Answer 2

Plate tectonics can help to explain which of the following?

A. land erosion

B. ocean currents

C. weather systems

D. trenches

Answer 3

The correct answer is:

D. trenches

Plate tectonics can help to explain the formation of oceanic trenches, which occur at convergent plate boundaries where one tectonic plate is subducted beneath another. This process leads to the creation of deep oceanic trenches in the Earth's crust.
