People as human resources are important because they can make the best uses of nature to create more resources by applying knowledge, skills and technology.

The density of material shows the denseness of that material in a specific given area. A material’s density is defined as its mass per unit volume. Density is essentially a measurement of how tightly matter is packed together. It is a unique physical property for a particular object. The principle of density was discovered by the Greek scientist Archimedes.  It is easy to calculate density if you know the formula and understand its related units.

Examples

Iron, platinum, and lead are examples of dense materials. Many types of rock and minerals are examples of dense material. Materials that are dense are most likely to ‘feel’ heavy or hard. The opposite of dense is sparse and a few examples of sparse material are glass, bamboo, aluminum, and styrofoam.

In general, liquids are less dense than solids and gases are less dense than liquids. This is due to the fact that solids have densely packed particles, liquids are materials where particles can slide around one another, and gases have particles that are free to move all over the place.

• Cooperative Sector Industries: These industries are owned and operated by the producers or suppliers of raw materials, workers or both. For example Anand Milk Union Limited and Sudha Dairy. Initially, in India most of the industries were under public sector but with passage of time privatisation was done at extensive level.

Cooperative sector industries are owned and managed by a group of people. Generally the members are the producers of raw materials. Examples of such industries are handloom, food processing and diary products. Amul is a example of cooperative sector society.

Industries owned and operated by the government are known as Public sector industries
Public sector industries are owned and operated by the government. For example, Hindustan Aeronautics Limited and Steel Authority of India Limited.

Industries owned and operated by the government are called public sector industries.

Answer: small scale and large scale industries.

Size refers to the amount of capital invested, number of people employed and the volume of production.

• Industries based on size are classified into small scale and large scale industries.
• Small Scale Industries:
  • Small scale industries manufacture products by hand and include cottage and household industry. These industries use lesser amount of capital and technology. For example, Basket-weaving, pottery, and other handicraft industries.
  • In India, small scale industry gives employment to around 35% population.
• Large Scale Industries:
  • Large scale industries produce large volumes of products. The investment of capital is higher and technology is superior. For example, production of automobiles and heavy machinery.
  • After independence, India gave emphasis to this sector for development.
• Most developed nations shows existence of large scale industries on the other hand more small scale industries are exist in developing and under developed world.

Industries can be classified according to their size

1.       Small Scale Industries

2.       Large Scale Industries

When products from seas and oceans are used as raw materials, it is called marine-based industry, e.g. sea food industry. Marine based industries use products from the sea and oceans as raw materials. Industries processing sea food or manufacturing fish oil are some examples.

• ndustries are divided on the basis of raw material, size, and ownership.

1. Raw Material:
   • Raw materials are basic material used in any industry and they can be classified on the basis of raw materials.
   • Industries under this are of agro-based(depends of agriculture products), mineral-based (based on mines),marine-based(water-based) and forest-based.
2. Size of Industries: Size refers to the amount of capital invested, number of people employed and the volume of production.
   • Industries based on size are classified into small scale and large scale industries.
   • Small Scale Industries:
     • Small scale industries manufacture products by hand and include cottage and household industry. These industries use lesser amount of capital and technology. For example, Basket-weaving, pottery, and other handicraft industries.
     • In India, small scale industry gives employment to around 35% population.
   • Large Scale Industries:
     • Large scale industries produce large volumes of products. The investment of capital is higher and technology is superior. For example, production of automobiles and heavy machinery.
     • After independence, India gave emphasis to this sector for development.
   • Most developed nations shows existence of large scale industries on the other hand more small scale industries are exist in developing and under developed world.
3. Ownership: On the basis of ownership, industries can be classified into the following sectors:
   • Private Sector Industries are owned and operated by individuals or a group of individuals. For example, Bharat Heavy Electrical Ltd., Indian Oil Cooperation.
   • Public sector industries are owned and operated by the government. For example, Hindustan Aeronautics Limited and Steel Authority of India Limited.
   • Joint Sector Industries are owned and operated by the state and individuals or a group of individuals. For example Maruti Udyog Limited.
   • Cooperative Sector Industries: These industries are owned and operated by the producers or suppliers of raw materials, workers or both. For example Anand Milk Union Limited and Sudha Dairy. Initially, in India most of the industries were under public sector but with passage of time privatisation was done at extensive level.

A n s w e r:
The industry refers to economic activity that is concerned with the production of goods, extraction of minerals, or the provision of services.
Industries are classified according to the raw material used, size, and ownership.

Mountains are useful to man in a variety of ways:
(i) Mountains are storehouse of water is the basic need of the human beings. Reservoirs are made and the water is harnessed for the use of people. Water is used for irrigation and generation of hydroelectricity.
(ii) Mountains have a rich variety of flora and fauna.
(iii) Mountains provide an idyllic site for tourists. They visit the mountains for their scenic beauty. 

Cooperative sector industries are owned and operated by the producers or suppliers of raw materials, workers or both. Examples — the sugar industry in Maharashtra, the coin industry in Kerala.

Geothermal energy is the energy obtained from the earth(geo) from the hot rocks present inside the earth. It is produced due to the fission of radioactive materials in the earth’s core and some places inside the earth become very hot. These are called hot spots. They cause water deep inside the earth to form steam. As more steam is formed, it gets compressed at high pressure and comes out in the form of hot springs which produces geothermal power.

Advantages of Geothermal Energy

1) It is a renewable source of energy.

2) By far, it is non-polluting and environment friendly. 

3) There is no wastage or generation of by-products.

4) Geothermal energy can be used directly. In ancient times, people used this source of energy for heating homes, cooking, etc.

5) Maintenance cost of geothermal power plants is very less.

6) Geothermal power plants don't occupy too much space and thus help in protecting natural environment. 

7) Unlike solar energy, it is not dependent on the weather conditions. 

Marine-based Industries: When products from seas and oceans are used as raw materials, it is called marine-based industry, e.g. sea food industry.

• दाढ़ी बनाते समय, ब्रश करते समय, सिंक में बर्तन धोते समय, नल तभी खोलें जब सचमुच पानी की ज़रूरत हो।
• गाड़ी धोते समय पाइप की बजाय बाल्टी व मग का प्रयोग करें, इससे काफी पानी बचता है।
• नहाते समय शॉवर की बजाय बाल्टी एवं मग का प्रयोग करें,काफी पानी की बचत होगी। इस काम के लिए आप भारत रत्न सचिन तेंदुलकर से प्रेरणा ले सकते हैं जो सिर्फ १ बाल्टी पानी से ही नहाते हैं।
• सार्वजनिक पार्क, गली, मौहल्ले, अस्पताल, स्कूलों आदि में जहाँ कहीं भी नल की टोंटियाँ खराब हों या पाइप से पानी लीक हो रहा हो तो तुरन्त जलदाय ऑफिस में या सम्बन्धित व्यक्ति को सूचना दें, इसमें हजारों लीटर पानी की बर्बादी रोकी जा सकती है।
• बाग़ बगीचों एवं घर के आस पास पौधों में पाइप से पानी देने के बजाय वाटर कैन द्वारा पानी देने से काफी पानी की बचत हो सकती है
• पानी की जरूरत को कम करने लिये, औद्योगिक क्षेत्र, कारखानों आदि में आधुनिक तकनीक को प्रयोग में लेना चाहिये।
