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
Sparta and Athens were city-states in the country of Greece.
Flooding can affect rivers because river flooding causes things to be picked up from the streets and pulled back into the water. So It affects the water quality and if anything dangerous to the fish and water life gets in the water it will mess up their life system. Hope this helped a little bit. :)
