Question

multiple choice
what is the primary cause of earthquakes?
a plate tectonics
b atmospheric pressure
c solar flares

Explanation:

To determine the primary cause of earthquakes, we analyze each option:

• Option A: Plate tectonics involves the movement of Earth's lithospheric plates. When these plates interact (e.g., collide, slide past, or move apart), stress builds up and is released as seismic waves, causing earthquakes. This is a well - established scientific explanation for most earthquakes.
• Option B: Atmospheric pressure is related to the pressure exerted by the Earth's atmosphere. It has no direct connection to the internal forces that cause the Earth's crust to move and generate earthquakes.
• Option C: Solar flares are eruptions of energy on the Sun's surface. They affect the Earth's magnetosphere and can cause auroras or disrupt communications, but they do not cause earthquakes.

Answer:

A. plate tectonics
