DAY 31 (17-10-23)
Q1. With reference to the High Ambition Coalition(HAC) for Nature and People, consider the following statements:
- It is an intergovernmental group championing a global deal for nature and people that can halt the accelerating loss of species and protect vital ecosystems that are the source of our economic security.
- India is not a member of the coalition.
- Its aim is to promote an international agreement to protect at least 30% of the world’s land and ocean by 2030 (Global 30×30 target).
Which of the statements given above is/are correct?
(a) 1 only
(b) 2 and 3 only
(c) 1 and 3 only
(d) 1 2 and 3
Answer: (c)
Explanation:
Statement 1 is correct:It is an intergovernmental group championing a global deal for nature and people that can halt the accelerating loss of species, and protect vital ecosystems that are the source of our economic security.It was launched in 2019 by Costa Rica, France and Britain.
Statement 2 is incorrect: India is the first of the BRICS (Brazil, Russia, India, China and South Africa) to join the HAC. It has more than 70 countries which are a mix of countries in the global north and south, European, Latin American, Africa and Asia countries are among the members.
Statement 3 is correct: Its aim is to promote an international agreement to protect at least 30% of the world’s land and ocean by 2030 (Global 30×30 target). It also aims to manage the planet sustainably with no net loss of natural habitats, supported by a circular economy, and strives for the sustainable and equitable sharing of benefits from nature.
Q2. Consider the following statements :
- Tropical zone extends from 10-degree to 25-degree North and South.
- Mid-latitude Zone extends from 55-degree to 60-degree North and South.
Which of the statements given above is/are correct?
(a) 1 only
(b) 2 only
(c) Both 1 and 2
(d) Neither 1 nor 2
Answer: (a)
Explanation:
Statement 1 is correct: Tropical zone extends from 10 to 25 degree north and south. It is the home of the world’s driest desert.
Statement 2 is incorrect:Mid-latitude Zone extends between 35 to 55 degrees north and south. The length of daylight varies significantly from winter to summer here, so seasonal contrasts in insolation are quite strong. Thus, these regions experience a large range in annual temperature.Subtropical Zones extends between 25 and 35 degrees north and south. These zones have a strong seasonal cycle and a large annual insolation.
Q3. The sequence of arrival of earthquake waves are :
(a) P-S-R-L
(b) S-R-P-L
(c) P-S-L-R
(d) S-R-L-P
Answer: (c)
Explanation:
Primary Waves (P): Longitudinal waves, both solid and liquid, velocity increases with density of medium. Highest velocity, energy, frequency but least wavelength and damage property. P shadow Zone due to refraction in liquid media.
Secondary Waves (S): Transverse Waves, only solid, deflected on reaching outer core. Medium damage, wavelength, frequency, energy, etc. S Shadow zone is formed.
Love (L) and Raleigh Waves: They are surface waves and don’t go deeper into the earth. L waves are faster than R waves so the sequence of arrival is PSLR.
Q4. Milpa, Conuco, and Ray are associated with?
(a) Type of Jhumming Agriculture
(b) Type of tropical fruit
(c) Type of water harvesting technique
(d) Type of organic fertiliser
Answer: (a)
Explanation:
Jhumming: The ‘slash and burn’ agriculture is known as ‘Milpa’ in Mexico and Central America, ‘Conuco’ in Venzuela, ‘Roca’ in Brazil, ‘Masole’ in Central Africa, ‘Ladang’ in Indonesia, ‘Ray’ in Vietnam. In India, this primitive form of cultivation is called ‘Bewar’ or ‘Dahiya’ in Madhya Pradesh, ‘Podu’ or ‘Penda’ in Andhra Pradesh, ‘Pama Dabi’ or ‘Koman’ or Bringa’ in Odisha, ‘Kumari’ in Western Ghats, ‘Valre’ or ‘Waltre’ in South-eastern Rajasthan, ‘Khil’ in the Himalayan belt, ‘Kuruwa’ in Jharkhand, and ‘Jhumming’ in the North-eastern region.
Q5. What is the primary purpose of a cryptocurrency?
(a) To act as a store of value
(b) To facilitate online purchases
(c) To serve as a medium of exchange
(d) To act as a speculative investment
Answer: (c)
Explanation:
Cryptocurrency, such as Bitcoin and Ethereum, is a digital or virtual currency that uses cryptography for security. It operates independently of a central bank or government. The main purpose of a cryptocurrency is to function as a medium of exchange, allowing for peer-to-peer transactions without the need for intermediaries.
