Answer:
Deep ocean exploration is all about investigating its geology i.e physical and chemical along with biological conditions on the ocean floor where sunlight cannot reach. There has been an interest in the deep ocean due to scientific communities and for industrial purpose. Exploration is carried by submarine and remotely operated vehicles at about 300m to 1000m. Analysis of ocean floor had found a huge concentration of mineral deposits such as manganese, copper, cobalt, gold, zinc etc.
The mining is carried out by using hydraulic pumping or bucket type excavator and are processed on ground industries. Deep-ocean mining has not been able to reach its full potential due to the high cost of operating and environmental damage.
Answer:
There are three types of soil erosion caused by water. They are: Sheet, Rill and Gully.
Sheet Erosion
This type of erosion takes away the top soil over a wide area thereby making it look as though it took a sheet of the top soil. As a result, this is not easy to notice at first glance because the soil from the whole area is gone so there is nothing to compare it to.
Rill Erosion
When water goes in channels and makes lines in the soil a by carrying off the soil that was previously on those lines, that is rill erosion. These channels must be shallow to be considered Rill erosion however because if they are too big, it would become gully erosion.
Gully Erosion
Gully erosion is much like Rill erosion but on a much larger scale. With gully erosion, the channels are much bigger and allow for more soil to be taken. Gully erosion can remove a lot of soil from an area. The Grand Canyon for instance was formed by Gully erosion.
