Answer:
transform boundary: when two plates slide past each other
divergent boundary: when two plates pull away from each other
convergent boundary: when two plates collide with each other
:)
The correct filling the blanks for the given statement are:
1. When two plates slide past each other, they form a transform boundary. Transform boundaries are also known as strike-slip boundaries, in which motion is predominantly horizontal. For example, San Andreas fault.
2. A divergent boundary occurs when two plates pull away from each other. The divergent boundary is formed when the plates are moving apart and a new crust is formed by pushing the mantle.
3. When two plates collide with each other, they form a convergent boundary. The colliding of two plates causes the edges to buckle up to form mountain ranges or deep-sea trench.
