Which of the following earth observation satellites have been launched by the Indian Space Research Organisation (ISRO)?
- RESOURCESAT- 2
- CARTOSAT-1
- Megha-Tropiques
- SARAL
- 1, 2 and 4 only
- 1, 2 and 3 only
- 2, 3 and 4 only
- 1, 2, 3 and 4
Answer : d
Explanation
India would launch its latest earth observation satellite EOS-01 and nine international customer satellites from Satish Dhawan Space Centre in Andhra Pradesh’s Sriharikota.
EOS-01 is an earth observation satellite and is intended for applications in agriculture, forestry and disaster management support.
Earth observation satellites are the satellites equipped with remote sensing technology. Earth observation is the gathering of information about Earth’s
physical, chemical and biological systems.
Many Earth observation satellites have been employed on sun-synchronous
orbit.
Other Earth observation satellites launched by Indian Space Research Organisation (ISRO) include RESOURCESAT- 2, 2A, CARTOSAT-1, 2, 2A, 2B, RISAT-1 and 2, OCEANSAT-2, Megha-Tropiques, SARAL and SCATSAT-1, INSAT-3DR, 3D, etc.
Q2:
Consider the following statements about National Air Quality Monitoring Program based Dashboard, choose the incorrect option:
- It is built on the data of CPCB’s National Ambient Air Quality Monitoring (NAAQM)
Network.
- Respirable suspended particulate matter (RSPM) are not recorded under the
National Air Quality Monitoring Programme (NAMP).
- 1 only
- 2 only
- Both 1 and 2
- Neither 1 nor 2
Correct Answer : 2
Explanation
The National Air Quality Monitoring Programme (NAMP) based dashboard is built on data from the Central Pollution Control Board’s National Ambient Air Quality Monitoring (NAAQM) Network which was started in 1984-85 and covers 344 cities/towns in 29 states and 6 UTs.
Under the NAMP, each station records about 104 observations a year covering four pollutants– Sulphur dioxide (SO2), nitrogen dioxide (NO2), suspended particulate
matter (SPM), and respirable suspended particulate matter (RSPM).
Q3:
With reference to India-Central Asia Dialogue, consider the following statements and choose the correct option:
- It is a ministerial-level dialogue between India and all the Central Asian countries.
- All the countries participating in the dialogue are also members of the Shanghai
Cooperation Organisation(SCO).
- 1 only
- 2 only
- Both 1 and 2
- Neither 1 nor 2
Answer : a
Explanation
India-Central Asia Dialogue is a ministerial-level dialogue between India and all
the Central Asian countries namely Kazakhstan, Kyrgyzstan, Tajikistan, Turkmenistan and Uzbekistan. All five nations became independent states after the collapse of the USSR in 1991, post-Cold war.
All the countries participating in the dialogue, except for Turkmenistan, are also members of the Shanghai Cooperation Organisation.
Q4:
Which of the following defence exercises are held between India and France?
- Exercise Shakti
- Exercise Varuna
- Exercise Indra
- Exercise Garuda
- 1 and 2 only
- 2 and 3 only
- 3 and 4 only
- 1, 2 and 4
Answer : d
Explanation
Exercise SHAKTI is a biennial exercise which is held between armies of India andFrance. It is conducted alternately in both countries.
Varuna naval exercise is an integral part of France–India strategic relationship in the 21 century and consists of naval cooperation drills.
Ex Garuda is a bilateral air training exercise between India and France. Exercise INDRA is a joint, tri services exercise between India and Russia.
The INDRA series of exercise began in 2003. It was conducted as a single service
exercise alternately between the two countries. However, the first joint Tri Services
Exercise was conducted in 2017.
Q5: Consider the following statements with respect to Green Crackers and choose the correct option:
- Green Crackers are manufactured using pyrotechnic to ensure that the emission of sulphur dioxide and nitrogen oxide does not occur.
- They have a chemical formulation that produces water molecules.
- They are made of chemicals such as lithium, arsenic, barium and lead.
- 1 and 2 only
- 1, 2 and 3
- 2 and 3 only
- 1 and 3 only
Answer: a
Explanation:
Green Crackers are manufactured using pyrotechnic to ensure that the emission of sulphur dioxide and nitrogen oxide does not occur.
They are known as ‘green’ firecrackers because they have a chemical formulation that produces water molecules, which substantially reduces emission levels and absorbs dust.
Green crackers don’t contain banned chemicals such as lithium, arsenic, barium and lead. They are called Safe Water Releaser (SWAS), Safe Thermite Cracker (STAR) and Safe Minimal Aluminium (SAFAL) crackers. Green crackers release water vapour and don’t allow the dust particles to rise.
