The salinity of sea ice ranges from? समुद्र में बर्फ की लवणता होती है: |
A) 0-3% B) 3-10% C) 11-17% D) 28-35% Correct Answer : 0-3% |
Which of these crops require hot climate and rainfall above 200 cm.? इनमें से किस फसल के लिए गर्म जलवायु और 200 सेमी से अधिक वर्षा की आवश्यकता होती है? |
A) Wheat /गेहूं B) Maize /मक्का C) Cotton /कपास D) Rubber /रबड़ Correct Answer : Rubber /रबड़ Explanation : Rubber is a tropical tree. It requires high temperature through out the year between 20–30°C. In some cases (younger trees), rubber trees can withstand a low temperature of around 15°C for a short period of time. An average rainfall of above 200cm is necessary for the latex tree cultivation. |
The best quality coal is? सबसे अच्छी गुणवत्ता का कोयला है? |
A) Anthracite /एन्थ्रेसाइट B) Bituminus /ब़िटुमिनस C) Lignite /लिग्नाइट D) Pea /पी Correct Answer : Anthracite /एन्थ्रेसाइट Explanation : Coal is a fossil fuel that is made from plant residues which lived and died million of years ago when parts of the earth were covered with huge swampy forests. Coal is classified as a nonrenewable energy source because it takes millions of years to build. Coal is classified into four main types are peat, lignite, bituminous, and anthracite. Peat Contains less than 40 to 55 per cent carbon.It is the first step in coal formation.peat contains a lot of moisture. It is a very soft brown coal. Lignite coal usually contains 40%–55% carbon.It is a soft brown coal that still contains a high amount of moisture.This is lower grade coal. Bituminous coal contains 45%–86% carbon. It is most widely available and used.It is a dense, compact, and is usually in black colour. Anthracite coal contains 86%–97% carbon and generally has the highest heating value of all ranks of coal. It is hard and dark black in color,and has very light weight when compared to other forms of coal, as there is very little moisture present in it.It is the highest grade of coal. |
