UPSC Essentials | Daily subject-wise quiz : Environment and Geography MCQs on Ecomark Scheme, tropical cyclone and more (Week 86)

1. A lukewarm oversea (a somesthesia implicit 26 degrees Celsius to a extent of 60 m)

2. Atmospheric instability

3. The ‘Eye’ of the tempest tin beryllium circular

4. Cumulus thundercloud

Select the close reply utilizing the codes fixed below:

(a) 1, 2 and 4

(b) 2 and 3 only

(c) 1 and 3 only

(d) 1, 2, 3 and 4

Explanation

— The India Meteorological Department (IMD) announced that the existing heavy slump volition apt intensify into a cyclone by Wednesday, with the tempest expected to attack the Tamil Nadu seashore wrong the adjacent 2 days.

— Once the tempest has intensified, it volition beryllium known arsenic Fengal, a sanction projected by Saudi Arabia. This is the 2nd cyclone of the post-monsoon play to deed the Indian coast, pursuing Cyclone Dana, which passed Odisha arsenic a’severe’ class tempest successful precocious October.

— The improvement rhythm of tropical cyclones whitethorn beryllium divided into 3 stages:

(i) Formation and Initial Development Stage

— A lukewarm oversea (over 26 degrees Celsius to a extent of 60 metres) with copious and turbulent evaporation of h2o vapour into the overlying atmosphere.

— Atmospheric instability promotes the accumulation of immense vertical cumulus clouds done convection with rising aerial supra the ocean’s surface.

(ii) Mature Tropical Cyclones

— When a tropical tempest intensifies, the aerial rises successful beardown thunderstorms and spreads horizontally astatine the tropopause level. When aerial spreads out, it creates a affirmative perturbation unit astatine precocious levels, which accelerates the downward question of aerial caused by convection.

— Subsidence induces aerial warming by compression, resulting successful a lukewarm ‘Eye’. The ‘Eye’ of a tempest has 3 main shapes: (i) circular, (ii) concentric, and (iii) elliptical.

— The superior carnal diagnostic of a mature tropical cyclone successful the Indian Ocean is simply a concentric signifier of highly turbulent gigantic cumulus thunderstorm bands.

(iii) Modification and Decay

— A tropical cyclone’s centre debased pressure, interior warmth, and exceptionally accelerated speeds statesman to wane arsenic soon arsenic its root of lukewarm bedewed aerial dries up oregon is abruptly chopped off.

— This occurs erstwhile it makes landfall oregon erstwhile it crosses crossed acold waters. The weakening of a cyclone does not bespeak that the menace to beingness and spot has passed.

Therefore, enactment (d) is the close answer.

QUESTION 2

With notation to the Ecomark Scheme, see the pursuing statements:

1. It is simply a binding strategy which promotes the labelling of household and user products based connected biology and prime parameters.

2. It is implemented by the Central Pollution Control Board (CPCB) successful concern with the Bureau of Indian Standards (BIS).

3. The Ecomark Rules, 2024 aligns with existing sustainability and environmentally affable practices and with the Environment Ministry’s Mission LIFE (Lifestyle for Environment), which promotes sustainable consumption.

How galore of the statements fixed supra are correct?

(a) Only one

(b) Only two

(c) All three

(d) None

Explanation

— The Union Environment Ministry has notified the Ecomark Rules, 2024, which recast its hallmark strategy for labelling eco-friendly items.

— It was established successful 1991 arsenic a voluntary and non-binding inaugural to beforehand the labelling of household and user items based connected biology and prime criteria. Hence, connection 1 is not correct.

— The Rules were notified to guarantee that they are accordant with existing sustainability and environmentally affable practices, arsenic good arsenic the Environment Ministry’s Mission LIFE (Lifestyle for Environment), which encourages sustainable consumption. Hence, connection 3 is correct.

— The rules picture the scheme’s conditions, procedures, verification method, and compliance mechanism. It besides includes a circumstantial acceptable of criteria that producers indispensable conscionable successful bid to beryllium granted the Ecomark.

— The criteria include, among different things, reducing contamination by minimising oregon eliminating discarded and biology emissions, utilizing recycled materials oregon producing recyclable products, reducing the usage of polluting vigor sources, and reducing the usage of environmentally hazardous materials.

— The inaugural volition beryllium carried retired by the Central Pollution Control Board (CPCB) successful collaboration with the Bureau of Indian Standards. Hence, connection 2 is correct.

Therefore, enactment (b) is the close answer.

QUESTION 3

Consider the pursuing statements:

1. It is India’s largest saline wetland.

2. Every year, the water attracts thousands of migratory birds.

3. It is located successful the authorities of Rajasthan.

4. It is designated arsenic a Ramsar Site.

The supra mentioned statements notation to:

(a) Sambhar Lake

(b) Rajsamand Lake

(c) Pichhola Lake

(d) Deedwana Lake

Explanation

— Sambhar Lake is India’s largest inland saltwater lake astatine 230 sq km, dispersed mostly across Jaipur and Nagaur districts and besides a portion of Ajmer.

— It has a catchment country of 5,700 quadrate km, with the h2o extent fluctuating betwixt 60 cm successful the adust play to astir 3 metres astatine the extremity of the monsoon.

— Every year, from November to February, the water attracts thousands of migratory birds from bluish Asia and Siberia, including tens of thousands of flamingos. When the monsoon arrives successful July, the water erupts with delight, accompanied by the chirping of avian taxon specified arsenic coots, black-winged stilts, sandpipers, and redshanks.

— Sambhar Lake has besides been classified arsenic a Ramsar Site.

Therefore, enactment (a) is the close answer.

QUESTION 4

Mount Erebus was successful the news. It is located in:

(a) Antarctica

(b) Philippines

(c) Italy

(d) Australia

QUESTION 5

With notation to the sedimentary rocks, see the pursuing statements:

1. They are formed from pre-existing rocks oregon pieces of once-living organisms.

2. These rocks bash not signifier successful lakes and oceans.

3. Marble is an illustration of sedimentary rocks.

Which of the statements fixed supra is/are correct?

(a) 1 and 2 only

(b) 2 only

(c) 1 only

(d) 2 and 3 only

Explanation

— Sedimentary rocks are created from pre-existing rocks oregon remnants of once-living organisms. Hence, connection 1 is correct.

— They originate arsenic deposits cod connected the Earth’s surface. Sedimentary rocks often grounds antithetic layering oregon bedding. Many of the magnificent landscapes of the godforsaken southwest diagnostic mesas and arches constructed of layered sedimentary rock.

— Sandstone, limestone, and shale are communal sedimentary rocks. These rocks are often formed from sediments carried by rivers and deposited successful lakes and oceans. When buried, sediments suffer h2o and get cemented, becoming rock. Marble is an illustration of metamorphic rocks. Hence, connection 2 and 3 are not correct.

Types of sedimentary rocks

(i) Clastic sedimentary rocks: They are made up of bits (clasts) of antecedently formed rocks. Weathering loosens pieces of rock, which are subsequently moved to a basin oregon slump wherever sediment is trapped.

(ii) Biologic sedimentary rocks: They signifier erstwhile a precocious fig of surviving organisms die. Chert is an illustration of this benignant of rock, and it is 1 of the ways limestone tin beryllium formed. Limestone tin besides signifier by precipitating straight from the water.

Therefore, enactment (c) is the close answer.
