Question

Assertion :New York City may submerge due to global warming. Reason: Due to global warming, glaciers are melting and due to this, sea-level will be certainly increasing which may cause flooding of cities situated at the banks of the seas. New York is one of them.

• A. Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
• B. Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
• C. Assertion is correct but Reason is incorrect
• D. Both Assertion and Reason are incorrect

Answer 1

Answer: (A)

Over the past century, the burning of fossil fuels and other human and natural activities have released enormous amounts of heat-trapping gases into the atmosphere.

These emissions have caused the Earth's surface temperature to rise and the oceans absorb about 80 per cent of this additional heat.

The rise in sea levels is linked to three primary factors, all induced by this ongoing global climate change. One of them is the melting of glaciers and polar ice caps.Large ice formations, like glaciers and the polar ice caps, naturally melt back a bit each summer. But in the winter, snows, made primarily from evaporated seawater, are generally sufficient to balance out the melting.

Recently, though persistently higher temperatures caused by global warming have led to greater-than-average summer melting as well as diminished snowfall due to later winters and earlier springs.

Hence, option A is correct.
