What are the boundaries of tectonic plates drawn along?

Question:

What are the boundaries of tectonic plates drawn along?

Tectonic Plate Movement:

Tectonic plates sit on top of the asthenosphere. Here, convection currents occur (due to the heating and cooling of the viscous rock). These currents put strain on the tectonic plates and cause them to move.

Answer and Explanation:

Boundaries of tectonic plates occur between two or more plates wherever they meet. Geological features such as oceanic trenches or ridges, mountain ranges or fault lines occur at plate boundaries. However, boundaries are not drawn along these features because they are there; rather, the features are formed because the boundary exists.
