What do we call a break in tectonic plates? (A)

## Step 1<br />The problem is asking for the term used to describe a break in tectonic plates. Tectonic plates are large pieces of the Earth's crust that move over the mantle. When these plates move, they can create breaks or fractures. <br /><br />## Step 2<br />The term used to describe these breaks or fractures is a "fault". A fault is a planar fracture or discontinuity in volumes of rock across which there has been significant displacement. <br /><br />## Step 3<br />Faults can range in size from microscopic to many kilometers. They are a fundamental aspect of plate tectonics and are responsible for many geological phenomena, including earthquakes.
