Plate tectonics：練習問題

What is the most significant characteristic of the asthenosphere that allows for the movement of tectonic plates?

Transform plate boundaries are characterized by plates sliding past each other horizontally. Which of the following is a typical feature or hazard associated with these boundaries?

The East African Rift Valley is an active continental rift zone. If the rifting process continues and intensifies over millions of years, what is the most likely long-term geological outcome for this region?

Which of the following layers of the Earth is characterized by its semi-fluid or plastic nature, allowing for the slow movement of overlying tectonic plates?

Which geological process is primarily responsible for the formation of intraplate volcanoes, such as the Hawaiian Islands, which are located far from active plate boundaries?

Name a type of natural hazard commonly associated with all three types of plate boundaries: divergent, convergent, and transform.

Explain how the process of seafloor spreading at mid-ocean ridges contributes to the expansion of ocean basins.

Discuss how the relative importance of 'ridge push' and 'slab pull' as driving forces for plate tectonics is inferred from observations of different types of plate boundaries, particularly emphasizing scenarios where one force dominates.
