Name the three types of plate boundaries and describe the movement that occurs at each.

1. The three types of plate boundaries are:

- **Divergent Boundaries**: At these boundaries, tectonic plates move away from each other. This movement typically leads to the formation of new crust, often seen at mid-ocean ridges where seafloor spreading occurs.

- **Convergent Boundaries**: Here, tectonic plates move towards each other. This movement can result in one plate being forced beneath another (subduction), leading to the formation of mountains, earthquakes, and ocean trenches.

- **Transform Boundaries**: At transform boundaries, tectonic plates slide past each other horizontally. This lateral movement can cause significant seismic activity, resulting in earthquakes.

2. What happens at divergent boundaries?

**Answer**: All of the Above (Mid-Ocean Ridges, Ocean Trenches, Volcanic Activity, Seafloor Spreading)

---

3. What happens at a convergent boundary?

**Answer**: All of the above (Subduction Zones, Ocean Trenches, Earthquakes, Mountains)

---

4. What happens at a transform boundary?

**Answer**: All of the above (Earthquakes, Fault zones, Ridges, Volcanic Activity)

5. What is the Ring of Fire, and why is it significant in the study of plate tectonics?

**Answer**: The Ring of Fire is a horseshoe-shaped area in the Pacific Ocean basin characterized by a high level of tectonic activity, including earthquakes and volcanic eruptions. It is significant in the study of plate tectonics because it demonstrates the effects of tectonic plate boundaries, particularly convergent and transform boundaries, and is home to around 75% of the world’s active and dormant volcanoes.

6. Who proposed the theory of continental drift, which eventually led to the theory of plate tectonics?

**Answer**: Alfred Wegener
