In the context of plate tectonics, which of the following best describes a divergent boundary?
A) A divergent boundary occurs where two tectonic plates move toward each other, leading to the formation of mountain ranges and deep ocean trenches.
B) A divergent boundary is characterized by two tectonic plates moving away from each other, which can create mid-ocean ridges and volcanic activity.
C) A divergent boundary involves the sliding of tectonic plates past one another horizontally, resulting in earthquakes and fault lines.
D) A divergent boundary refers to the area where tectonic plates converge and overlap, causing subduction zones and volcanic arcs.
