geomorphology & earth landforms section 1 MCQ Questions & Answers Detailed Explanation

Answer: (c)

Geologically, a fjord is a long, narrow inlet with steep sides or cliffs, created in a valley carved by glacial activity. A fjord is formed when a glacier cuts a U-shaped valley by ice segregation and abrasion of the surrounding bedrock.

Glacial melting is accompanied by the rebound of Earth's crust as the ice load and eroded sediment is removed. Both the whole coast of Norway and the island of Greenland have many fjords.

Cliffs, caves, arches, stacks are some of the landforms produced by wave erosion. Coves form where rock runs in bands horizontal to the direction of wave attack.

There is a band of resistant rock closest to the sea and a band of less resistant rock inland. The waves seek out faults in the hard rock and erode using the processes of abrasion/corrosion and hydraulic action through to the soft rock behind.

Answer: (d)

Answer: (a)

A geyser is a spring characterized by intermittent discharge of water ejected turbulently and accompanied by a vapour phase (steam).

The word geyser comes from Geysir, the name of an erupting spring at Haukadalur, Iceland; that name, in turn, comes from the Icelandic verb geysa, “to gush”, the verb itself from Old Norse.
