Answer 8)
One can identify the largest or smallest ocean on the basis of the area it covers. The Pacific ocean is the largest ocean in the world with an area of around 162 million square kilometres while the Arctic ocean is the smallest ocean with an area of only 5.4 million square kilometres.
Answer 9)
Seawater is very saline indicating that salt (NACl) is found in abundant quantities in it. Chlorine is the most abundant element in seawater because it has long residence time and do not precipitate much quickly as compared to other elements. Chlorine is generally more than sodium because of the differences in atomic weights, with more chlorine required for every 1 gm of sodium for the salt to form.
Answer 10)
The continental rise is an oceanic feature found between the continental slope and the abyssal plane. Here, the abyssal plane refers to an underwater plain area found in deep oceans and continental slope is the inclination when transiting from the continental shelf towards the ocean.
Continental rise is a wide, gentle incline from an ocean bottom to a continental slope. It is fomed because the river and stream water moving towards the sea is loaded with sediment that eventually settles out in the ocean. Because the continental slope is steep, it's more difficult for them to settle there, so the sediment accumulates at the continental rise instead.
Answer 11)
Since the graph is not available fully, I cannot give you an answer but I can show you an example and you can find the answer with the full graph.
For example, at 60 degrees, the land area is about 75 million square kilometres and the oceanic area is about 25 million square kilometres. dividing the area of ocean with land we get ratio of 1:3. so you can make rough measurements like these over the area and find the answer.
All the best!!
