Answer 1

1. What happens at divergent boundaries?
   The correct answer is All of the Above. At divergent boundaries, plates move apart, leading to the formation of mid-ocean ridges, ocean trenches, volcanic activity, and seafloor spreading.

2. What happens at a convergent boundary?
   The correct answer is All of the above. At convergent boundaries, tectonic plates move towards each other, which can result in subduction zones, ocean trenches, earthquakes, and the formation of mountains.

3. What happens at a transform boundary?
   The correct answer is All of the above. Transform boundaries are characterized by plates sliding past each other, resulting in earthquakes and the creation of fault zones, although they do not typically form ridges or significant volcanic activity.

4. What is the Ring of Fire, and why is it significant in the study of plate tectonics?
   The Ring of Fire is a horseshoe-shaped zone in the Pacific Ocean basin that is characterized by a high level of tectonic activity, including numerous earthquakes and volcanic eruptions. It is significant because it outlines the boundaries of several tectonic plates, illustrating the relationship between plate tectonics and seismic activity. This area is crucial for understanding the dynamics of plate movements and their geological consequences.

5. Who proposed the theory of continental drift, which eventually led to the theory of plate tectonics?
   The correct answer is Alfred Wegener. He proposed the theory of continental drift in the early 20th century, suggesting that continents were once joined together and have since drifted apart. This idea laid the groundwork for the later development of the theory of plate tectonics.
