Answer:
1. oceanic-oceanic boundaries
2. oceanic-continental boundaries
3. continental-continental boundaries
Explanation:
The three types of plate convergence are:
1. oceanic-oceanic boundaries: this occurs when two oceanic plates clash; thereby the heavier plate forms below the lighter plate resulting in dark, heavy, basaltic volcanic islands.
2. oceanic-continental boundaries: this occurs when there is a collision between oceanic and continental plates, resulting in the downward movement of oceanic plate, while the volcanic arc rises on land
3. continental-continental boundaries: this occurs due to the massive crust of slabs clashing against each other. Thereby leading to big mountains forming from folded, faulted, and thickened convergent boundaries
Answer:
The embryological data have advantage over DNA evidence.
Explanation:
- Embryology is the study of earliest phase of any organism i.e development and formation of embryos.
- The embryological data is very important because it give the proper information about the mechanisms that have both normal and abnormal development.
- Similarly the embryological data also helps in studying the evolution over the generations.
- The overall organization, its process of development can be properly known by embryology over DNA evidence.
