Context

New images from the North Sea show never-before-seen landforms that were carved by a single, colossal ice sheet 1 million years ago and subsequently buried beneath a thick layer of mud.

About North Sea

North Sea is a relatively shallow and enclosed sea located in Northwestern Europe.
It is considered to be a marginal sea of the Atlantic Ocean.
It connects to the Atlantic Ocean via the Norwegian Sea in the north and the English Channel in the south.
It connects to the Baltic Sea in the east via the Kattegat and Skagerrak straits
Bordering Countries: United Kingdom, Norway, Denmark, Germany, the Netherlands, Belgium and France.
It covers an area of approximately 570,000 sq.km.
It also hosts two of the world’s largest ports (Hamburg and Rotterdam).
It is one of the most important fishing grounds globally.

Major rivers that drain into the North Sea include

Elbe

Weser

Ems

Rhine

Meuse

Scheldt

Thames

PRACTICE QUESTION

Q. Recently, scientists discovered massive Ice Age landforms deep beneath the North Sea. With reference to this discovery, consider the following statements:

The landforms were identified using high-resolution seismic data.
The discovery suggests that multiple small ice sheets covered the region around 1 million years ago.
This finding provides new insights into glacial processes and climate history.

Which of the statements given above is/are correct?

(a) 1 and 2 only

(b) 2 and 3 only

(d) 1, 2 and 3

Answer: (c)

Explanation

Statement 1 is correct

Scientists used high-resolution seismic data to detect the landforms buried under approximately 1 kilometer of sediment.

Statement 2 is incorrect

The discovery suggests the presence of a single massive ice sheet, rather than multiple small ice sheets, covering the region around 1 million years ago.

Statement 3 is correct

The findings contribute to a better understanding of glacial processes and Earth's climate history, shedding light on ancient ice sheet movements.
