Answer:
5. Answer in detail.
Question 1.
The marine pollution is ultimately going to be harmful to the man himself. Discuss.
Answer:
Question 2.
There is similarity in the relief on the land surface and the ocean bottom.
Answer:
Ocean tourism is developed along the coastal areas of seas and oceans-
Ocean tourism comes in many forms like cruises, scuba-diving, fishing, beach tourism, etc. Such activities are increasingly becoming popular.
Generally, water sports activities such as scuba diving, surfing, water skiing, etc., are developed along the coastline. For example, sport activities along the coast of Goa.
There is beautiful scenery along the coastline due greenery of trees along the coast, huge waterbody of sea or ocean, clean air and coolness due to nearness to water, therefore many resorts, hotels, marina, etc., are developed and coastal areas have become popular for tourism. For example, tourism along Konkan coastline. The cruise tourism is also increasing.
Question 3.
Discuss how development of oceanic tourism should be carried out without disturbing marine life.
Answer:
It is difficult to clean up mass pollution once it has occurred, so the best plan is prevention. Several changes can take place to help keep industry in check and encourage sustainable practices such as:

1. Look at figure 6.1 and answer the following question. (Textbook Page No. 68)
Question 1.
What does the figure show?
Answer:
The figure shows various landforms of the ocean floor.
Question 2.
In which part of the figure is the ocean shallow? Which human activities can be carried out here?
Answer:
The ocean is shallow at the continental shelf area. Fishing is carried out here as a major human activity.
Question 3.
In which part does deposition of sediments occur?
Answer:
Deposition of sediments occur on the continental shelf area as well as on the abyssal plains.
Question 4.
Where in the figure do you find islands formed due to submerged mountains?
Answer:
