What are the three types of boundaries? • Divergent Boundaries • Convergent Boundaries • Transform Boundaries Divergent Boundaries A plate boundary where two plates move away from each other. wrote "Our wondering continents" ii. There are three main types of plate boundaries: divergent boundaries where plates move apart, convergent boundaries where plates collide, and transform boundaries where plates slide past each other. Goals • Classify and label the types of movement at plate boundaries, using a world map that shows relative plate motions • Identify the distribution of plates by means of the world map of relative plate motions • Describe the present plate-tectonic setting of your community, and infer possible past plate-tectonic activity based on your knowledge.
