Hello, kindly confirm my work, all questions are well detailed as per your instructions.For clearly understanding, I decided to answer each question separately as per your instructions.
Among the four main natural processes which decrease seawater salinity include: runoff
from land, precipitation, sea ice melting and icebergs melting. These four processes reduce
seawater salinity through adding more water in the sea to reduce level of salt concentration.
Reducing salt concentration is an implication of low salinity in seas (David and Saucède).
Among the two main processes increasing seawater salinity involve evaporation and
formation of sea ice. Both processes involve reducing amount of fresh water in the seas which in
turn results to high levels of salt concentration (David and Saucède).
The main processes of marine pollution involve oil spills from ships and sewage disposal.
In most cases, ships encounter oil leakages as they transport commodities across oceans. These
oils serve as impurities hence polluting ocean water. Impacts associated with oil pollution in seas
incorporate death of aquatic life (David and Saucède). Sewage disposals involve animal waste and
human wastewater which is often washed all the way into ocean. Untreated sewage comprise of
pathogens and microbes which affect aquatic life in the oceans.
Oil spills is the main form of ocean pollution. This is because, offshore drills lead to
leakages in to the oceans. Ships transporting oils products end up leaking large percentage of oils
in oceans. Additionally, people also contribute to oil pollution in oceans through pouring
cooking oils and grease which is later drained into oceans (David and Saucède).
When water freezes, its molecules result to formation of crystalline structure retained by
hydrogen bonding. This crystalline structure is termed as ice which floats on liquid water. By
floating on water, this implies tha...
