Question 23 Marks

Write a short note on Oceanic mineral resources.

Answer

The biological and inorganic resources associated with ocean water and its bottoms are called marine resources. The classification of marine resources is as follows:

1. Marine Biological Resources:

Plankton, diatoms, seaweed, seaweed, different types of fish, corals and different types of oysters, shells etc.

2. Marine Mineral Resources:

Minerals dissolved in seawater include salt, bromine, magnesium, zinc, uranium, thorium, etc. Minerals such as magnetite, monazite, sulfur, diamonds, etc. are found in sedimentary deposits.

3. Energy Resources:

(i) Conventional energy sources:

There are many areas where oil and natural gas can be found from the bottom of the ocean.

In the Arabian Sea, mineral oil is obtained by drilling at the bottom of the sea at Bombay High near Mumbai in India.

(ii) Unconventional energy sources:

Tidal energy can be obtained by using tidal waves and tidal waves.

Electricity can be generated from waves bouncing in Fundy Bay.

Question 33 Marks

Mention the types of resources distribution point of view.

Answer

The types of resources in terms of distribution are as follows:

Ubiquitous resource, general accessible resource, potential resource, unknown resource etc.

The gases in the atmosphere like nitrogen, oxygen etc. are the most accessible resources.

Land, water, pastures, etc. are generally accessible resources.

Resources that are likely to be used in the near future are potential resources.

For example, in the hilly regions of the states of Uttarakhand, Himachal Pradesh, etc. in North India, there are many conveniences for hydropower.

Such substances are unknown resources unless one knows the properties of the substance and its use.

For example, the inhabitants of the Amazon River Delta knew rubber trees.

But did not know its use.

So rubber at the time called an unknown resource.

The main animal for the dairy industry is the cow.
On a commercial basis, the dairy industry is further developed in the USA, the former Soviet Union, Canada, France, the Netherlands, Denmark, Belgium, Argentina, etc.
Gujarat's Amul Dairy has caused a white revolution in the state.

2. Meat industry:

Cows, pigs, sheep, goats, etc. are raised for meat production in the world.
The industry has developed further in European countries, China, Canada, Brazil, Argentina etc.

3. Warm textile industry:

Australia is the world's largest producer of wool.
In India, warm textile industry is run in Amritsar, Ludhiana, Srinagar, Varanasi, Agra etc.
The warm textile industry has developed in the USA, Canada, European countries, China, the former Soviet Union, India and other countries. Warm cloth is made from sheep's wool.

Question 53 Marks

Give brief information about surface water.

Answer

Major rivers like Ganga, Yamuna, Brahmaputra, Narmada, Tapi, Godavari, Sutlej, Kaveri etc. flow in India.
These rivers are a very important and widespread form of surface water resources of the country.
Surface water is also available in the form of lakes, ponds and springs.
States like Uttar Pradesh, Himachal Pradesh, Jammu and Kashmir receive snowfall in addition to rainfall.
So even in these states surface water remains more accessible.
Dams have been built on the rivers with more water in India.
This has led to the creation of huge artificial reservoirs.
There are artificial reservoirs like Govindsagar, Sardar Sarovar, Nizamsagar, Nagarjunasagar etc.
These lakes can be drained to distant areas.
All these canals benefit millions of hectares of irrigated land.
With the Arabian Sea in the west, the Bay of Bengal in the east, and the Indian Ocean in the south, seawater is also accessible.
