Then again, the discontinuous arrangement depicts the development of the mafic minerals, for example: pyroxene, olivine, biotite mica and amphibole each at an unmistakable temperature.

Ocean
Explanation:
The ocean is the final basin that collects all water on the earth surface. Rivers and streams inland all flows sea ward and collects in oceans.
As the last drainage basin, it is the largest pool of water on the earth surface. It occupies about 70% of the total land area.
- In the hydrologic cycle, water transitions between the land and the atmosphere in a cyclic fashion presenting water in different states of matter.
- For water to move into the atmosphere, it is evaporated from the land area and through evapotranspiration process in plants.
- The ocean being the largest water body on the earth surface is the largest source of water into the atmosphere.
- About 90% of all the water vapor is made up of the those evaporated from the surface of the ocean.

The correct answer is: <span>landslides or mudslides</span>.

On the other hand, landslides and mudslides are very catastrophic and can wipe entire villages.
