What is the name for an amphitheater-like hollow that forms at the head of a glacier?

  1. Kettle

  2. Moraine

  3. Cirque

  4. Horn
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Cirque is a bowl-shaped, amphitheater-like depression eroded into the head or the side of a glacier valley. Typically, a cirque has a lip at its lower end. A cirque may also be a similarly shaped landform arising from fluvial erosion.

Which of the following agents of erosion deposits the most poorly sorted sediment?

  1. Wind

  2. Streams

  3. Ice

  4. Ocean currents
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Ice is the poorest sorter of sediment. Glaciers can transport almost any size sediment easily, and when ice flow slows down or stops, the sediment is not deposited, due to the density of the ice. As a result, sediments deposited directly by ice when it melts are usually very poorly sorted. Significant sorting only occurs in glacial sediments that are subsequently transported by melt water from the glacier. Wind, on the other hand, is the best sorter of sediment, because it can usually only transport sediment that ranges in size from sand to clay. Occasional variation in wind speed during transport serves to further sort out these sediment sizes.

Due to the denudation work of __________ moraines are formed.

  1. glaciers

  2. wind

  3. river

  4. magma
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

When glaciers melt or recede they deposit the rock materials brought by them in heaps of various shapes and size. These are known as moraines. Moraines are depositional feature and consist of rock materials of heterogeneous shape and size.

Choose the odd one out.

  1. Cyclone

  2. Earthquake

  3. Seismograph

  4. Tsunami
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation
In meteorology, a cyclone is a large scale air mass that rotates around a strong center of low atmospheric pressure. Cyclones are characterized by inward spiraling winds that rotate about a zone of low pressure
While seismograph is an instrument used to detect and record earthquakes. A tsunami is an earthquake in oceans.

The severity of Earthquake is measured on ________________.

  1. richter scale

  2. rain gauze

  3. thermometer

  4. None of these
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The Richter magnitude scale was developed in 1935 by Charles F. Richter of the California Institute of Technology as a mathematical device to compare the size of earthquakes. The magnitude of an earthquake is determined from the logarithm of the amplitude of waves recorded by seismographs.
