NICE Environmental Science & Engineering Question Paper

Unit – I

Part A :
1. Define Environment. :
The Physical, chemical and biological presence of living and non-living things outside an individual species is called as its environment. According to ISO 14001, environment can be defined as, “Surroundings in which an organization operates, including air,water,land, natural resources,flora,fauna,humans and inter relation”.

2. What are all the categories of environment? :
The main categories of environment are biotic and abiotic environments. The abiotic environment can further be classified into atmosphere (air),lithosphere(soil),and hydrosphere(water). The biotic environment is called as biosphere.

3. Write the components of environment? :
1. Air(Atmosphere)
2. Land(Lithosphere)
3. Water(Hydrosphere)

4. Mention any two awareness programme of environmental issuses to student? :
1. Participating in seminars and courses related to environment issues.
2. Discussion with people about the environmental problems.

5. Define deforestation?
Deforestation refers to the removal of plants in the forest.

6. List the Causes of deforestation? :
1. Slash and Burn farming.
2. Commercial agriculture.
3. Cattle ranching and livestock grazing.
4. Mining and petroleum exploration.
5. Infrastructure development.
6. Fuel wood collection.
7. Tree Plantations.

7. Define Surface water. :
Precipitation that does not soak into the ground or return to the atmosphere by evaporation or transpiration is called surface water. It forms streams, lakes, wetlands, and artificial reservoirs.

8. What is Groundwater? :
The subsurface area where all available soil and rock spaces are filled by water is called the zone of saturation, and the water in these pores is called ground water.

9. What is Rock? :
Rock is any material that makes up a large natural, continuous part of the earth’s crust. Some kinds of rock, such as limestone (calcium carbonate, or CaCO3) and quartzite(silicon dioxide or SiO2), contain only one mineral,but most rocks consist of two or more minerals.

10. Give the classification of Mineral Resources. :
Energy resources (coal,oil,natural gas, uranium, and geothermal energy; metallic mineral resources (iron,copper,and aluminium) and nonmetallic minerals resources(salt,gypsum,and clay, sand, phosphates, water, and soil).

Unit – II

11. Classify food production. :
There are two types of food production
1. Industrialized Agriculture Subsistence Agriculture
2. Traditional Agriculture
Intensive Agriculture

12. Define Traditional Agriculture. :
Traditional Agriculture can be classified as Traditional Subsistence agriculture and Traditional Intensive agriculture.
Traditional Subsistence agriculture produces enough crops or live stock for a farm family’s survival and in good years, a surplus to sell or put aside for hard times.
In Traditional Intensive agriculture farmers increase their inputs of human and draft labour, fertilizer, and water to get a higher yield per area of cultivated land to produce enough food.

13. List some of the food resources available in the world. :
Major food sources available in the world to cater the human’s hunger are 12 types of seeds and grains, 3 root crops, 20 common fruits and vegetables, 6 mammals, 2 domestic fowl, few fishes and other forms of marine life,etc.

14. Classify energy resources? :
Available conventional energy sources can be divided into two categories
1) Renewable Energy Sources
2) Non Renewable Energy Sources

15. Draw the flow chart of petroleum fractionation process. :
Fuel gas, Propane Gasoline Kerosene Furnace Diesel Lubricants Asphalt
Butane liquefied gas oil
Heated crude oil

16. Write the advantages and disadvantages of petroleum as a energy resources? :
As a source of energy petroleum has many advantages :
1) It is relatively cheap to extract and transport
2) It requires little processing to produce desired products and
3) It has relatively high net and useful energy yield.

However it has certain disadvantages also, :
1) Produces Environmental pollution
2) Oil spills, in ocean cause water pollution and is expensive to clean up.

17. Write short notes on petroleum gas :
It is the mixture of three hydrocarbons butane, propane and ethane. The main constituent of petroleum gas is butane. The above gases are in gaseous state in ordinary pressure but they can be liquefied under high pressure. So it is called as LPG. (Liquefied petroleum Gas).

A domestic cylinder contains 14 kg of LPG. A strong smelling substance called ethyl mercaptian is added to LPG gas cylinder to help in the detection of gas leakage.

18. What is fission neutrons? :
The fission process is accompanied not only by the release of energy also it releases neutrons called as fission neutrons.

19. Name the several types of nuclear reactors :
1. Light water Reactor(LWR)
2. Heavy water Reactor(HWR)
3. Gas Cooled Reactor(GCR)
4. Boiling Water Reactor(BWR)
5. Pressurised Water Reactor(PWR)
6. Liquid Metal Fast Breeder Reactor(LMFBR)

20. List some of the renewable energy sources :
1. Solar energy
2. Wind energy
3. Hydro energy
4. Geo-thermal energy
5. Ocean thermal energy
6. Biogas
