PRACTICE QUESTION

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

1. The landforms were identified using high-resolution seismic data.
2. The discovery suggests that multiple small ice sheets covered the region around 1 million years ago.
3. 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

(c) 1 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.
