UPSC Environment Quiz Covers Wildlife, Floods, El Niño
This quiz tests knowledge about animals, floods, and weather patterns.
Orangutans live in the rainforests of Borneo and Sumatra.
They are the biggest mammals that spend most of their time in trees, and all three species are Critically Endangered.
Bats are not completely protected from viruses, but their bodies can control some infections unusually well.
They also help plants grow by pollinating them and reduce insect populations.
Floods are named Normal, Above Normal, Severe, or Extreme depending on river-water levels.
A Great Indian Bustard chick was produced using a fertile egg and a female bird in Gujarat.
El Niño is warming in the equatorial Pacific that can bring hotter temperatures and weaker rainfall to India.
The quiz explains that orangutans are Asia’s only great apes and the largest arboreal mammals, but all three species are Critically Endangered, not Vulnerable.
Bats have two copies of antibody-related gene sets, tolerate some viruses rather than being completely immune, and support pollination and insect control.
The Central Water Commission classifies floods as Normal, Above Normal, Severe, or Extreme according to warning, danger, and highest flood levels.
The Great Indian Bustard recorded India’s first birth through the “jumpstart” method after a fertile egg was transported from Rajasthan to Gujarat.
All three El Niño statements are correct: it warms the equatorial Pacific, is linked to heat and subdued rainfall in India, and can reduce marine productivity.
- Who
- UPSC Essentials, with information on orangutans, bats, flood classification, the Great Indian Bustard, and El Niño.
- What
- An Environment and Geography multiple-choice quiz containing five questions and explanations.
- When
- The specific publication date is not stated; the article identifies it as a daily subject quiz in Week 179.
- Where
- The quiz concerns India, the equatorial Pacific Ocean, and orangutan habitats in Borneo and Sumatra.
- Why
- It is intended to help aspirants revise important static topics for civil-service examinations.
- Orangutan status
- All three orangutan species are classified as Critically Endangered on the IUCN Red List.
- Bat adaptation
- The world’s largest bat family has two distinct copies of genes involved in producing antibodies.
- Flood categories
- The Central Water Commission uses four categories: Normal, Above Normal, Severe, and Extreme.
- Extreme flood threshold
- An Extreme flood occurs when the river reaches or crosses the highest flood level recorded at a forecasting site.
- Jumpstart method
- A fertile Great Indian Bustard egg was transported from Jaisalmer, Rajasthan, to Naliya, Gujarat, for incubation by a female bird.
- Great Indian Bustard population
- The article estimates about 150 Great Indian Bustards in the wild in India.
- El Niño
- El Niño is abnormal warming of sea-surface temperatures along the equatorial Pacific Ocean.
