Final answer:
Tension is the stress force that pulls on the crust where two plates are moving apart
Step-by-step explanation:
Tension is the stress force that pulls on the crust where two plates are moving apart. It is a type of stress that occurs at divergent plate boundaries. When plates move apart, a gap or rift forms between them, creating tension. This tension causes the crust to stretch and leads to the formation of features like synclines and anticlines.
