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
evaporation is when a mass of water is hit by sunlight and some of it turns to a vapor. In the atmosphere, that vapor cools and the water molecules fuse with other water molecules, forming clouds. (condensation) When the clouds become full, the water precipitates onto land or into the ocean in the form of rain, sleet, snow or hail (precipitation).
