Which crustal features MOST LIKELY form at divergent boundaries and at convergent boundaries? Move the correct answers to each box. Not all answers will be used. Mid-ocean ridges, Hot spots Mountain ranges, Volcanoes ,Rift valleys
To determine the type of plate boundaries A, C, and D represent, we need to understand the characteristics of each type.
1. Convergent boundaries occur when two tectonic plates collide or come together. This collision can result in the formation of mountain ranges, volcanic activity, and sometimes earthquakes.
2. Divergent boundaries happen when two tectonic plates move away from each other, creating a gap or rift. This separation allows magma to rise from the mantle, forming new crust and creating features like mid-ocean ridges and rift valleys.
3. Transform fault boundaries occur when two tectonic plates slide past each other horizontally. This movement can cause powerful earthquakes.
Now, let's determine the type of plate boundaries A, C, and D represent based on the given options:
- If all three options are correct, then the correct answer is "All of the above."
Regarding the crustal features at location D, we can derive the answer based on the type of plate boundary represented. Since D is a transform fault boundary, its major characteristic is the occurrence of powerful earthquakes. Therefore, the crustal feature at D would likely involve more seismic activity rather than volcanic activity.
Note that while the provided answer options mention features like "oceanic volcanoes and island arcs" as well as "volcanic mountains," these are more commonly associated with convergent boundaries where one plate subducts beneath another. In the case of a transform fault boundary like D, the main crustal feature would be the result of fault movement and seismic activity.
Keep in mind that the information provided here is a general understanding, and specific geological contexts may lead to variations in features and processes observed at different plate boundaries.
