[Mission 2022] QUIZ – 2022: INSIGHTS STATIC QUIZ, 13 November 2021 – Geography

Solution: a)

A complex volcano, also called a compound volcano, is defined as one that consists of a complex of two or more vents, or a volcano that has an associated volcanic dome, either in its crater or on its flanks.

A complex volcano does not rise from the ground as a distinct, singular dome but consists of multiple stratovolcanoes (volcanoes susceptible to explosive eruptions), conical hills and craters of all shapes and sizes.

Solution: c)

Solution: a)

• Fold mountains are created where two or more of Earth’s tectonic plates are pushed together. At these colliding, compressing boundaries, rocks and debris are warped and folded into rocky outcrops, hills, mountains, and entire mountain ranges.
• Fold mountains are created through a process called orogeny. An orogenic event takes millions of years to create a fold mountain.
• Fold mountains are often associated with continental crust. They are created at convergent plate boundaries, sometimes called continental collision zones or compression zones. Convergent plate boundaries are sites of collisions, where tectonic plates crash into each other. Compression describes a set of stresses directed at one point in a rock or rock formation.
• Most fold mountains are composed primarily of sedimentary rock and metamorphic rock formed under high pressure and relatively low temperatures.
• Fold mountains are the most common type of mountain in the world. The rugged, soaring heights of the Himalayas, Andes, and Alps are all active fold mountains.

Solution: a)

A geomagnetic reversal is a change in a planet’s magnetic field such that the positions of magnetic north and magnetic south are interchanged (not to be confused with geographic north and geographic south). Reversal occurrences are statistically random.

The only major, noticeable effect that’s guaranteed to occur when the polar flop is finished is that your compass needle will tell you that North is in Antarctica and South is somewhere near Canada.

Another interesting consequence will be that animals that use Earth’s magnetic field for navigation—including birds, salmon, and sea turtles—could get lost during their routine journeys.

Solution: c)

Teesta River originates from the Pahunri glacier. Brahmaputra originates in Angsi glacier. Teesta is a tributary of Brahmaputra.

But, Teesta flows through West Bengal and Sikkim, before going to Bay of Bengal through Bangladesh.

Rangeet is a tributary of the Teesta River, which is the largest river in Sikkim. It also originates in Sikkim.
