Weathering of rocks occurs due to

  1. Strong winds

  2. Flowing water

  3. Heating and cooling of rocks

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Strong winds, flowing water and heating and cooling of rocks leads to its breakdown. They break the tough rock particles and convert them into smaller ones. They also create cracks in them.

So, option D is the correct answer.

Depositional work of glaciers along the sides of it is known as ______________.

  1. Drumlins

  2. Eskers

  3. Moraine

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

Glacial deposition is the settling of sediments left behind by a moving glacier. As glaciers move over the land, they pick up sediments and rocks. The mixture of unsorted sediment deposits carried by the glacier is called glacial till. Piles of till deposited along the edges of past glaciers are called moraines.

Origin of typical land form of glacier i.e. Drumlins is _____________.

  1. Due to erosion

  2. Due to accumulation

  3. Both (A) and (B)

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

Drumlin, oval or elongated hill believed to have been formed by the streamlined movement of glacial ice sheets across rock debris, or till. The name is derived from the Gaelic word druim (“rounded hill,” or “mound”) and first appeared in 1833.

Large deposited material at the mouth of glacier is known as _________.

  1. Kame

  2. Kettle

  3. Eratics

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

Larger pieces of rock that are encrusted in till or deposited on the surface are called "glacial eratics". They range in size from pebbles to boulders, but as they are often moved great distances, they may be drastically different from the material upon which they are found.

Point out the term which describes the action of glacier and its effects on the previous landscape?

  1. Glacioscerpe

  2. Glaciations

  3. Fluvialglacio

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

Fluvioglacial landforms are landforms molded by glacial meltwater. This discharge of glacial streams, both over the surface and beneath the ice sheet, is higher in the warmer summer months. As subglacial water often flows under pressure, it has a high velocity and is very turbulent.

Wind erosion has the greatest impact on areas with __________.

  1. wet soil

  2. dry soil

  3. both a and b

  4. none of these
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Wind erosion has the greatest impact on areas with dry soil because it is easier for wind to pick up and transport dry, light soil. Characteristically, deserts have dry soil, or sand, that is easy to transport. Also, deserts often have fewer physical barriers, such as hills, trees, or other structures, that can slow the wind movement.

Erosion is the process of ____________________.

  1. Disintegration of rocks

  2. Decomposition of rocks

  3. Cutting and removal of land by running water, wind and ice

  4. Deposition of material
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Erosion is the geological process in which earthen materials are worn away and transported by natural forces such as wind, water, or ice.

A mass of rocks and sediment carried down and deposited by a glacier, typically as ridges at its edges or extremity is called ____________.

  1. Ice caps

  2. Folded mountains

  3. Moraines

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

Moraines are accumulations of dirt and rocks that have been pushed along by a glacier as it moves, often forming ridges at the edges.

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.

Ox bow lakes are found in _________.

  1. Glaciers

  2. River valleys

  3. Deserts

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

Oxbow lakes are found in river valleys.
An oxbow is a crescent-shaped lake lying alongside a winding river. The oxbow lake is created over time as erosion and deposition of soil change the river's course.

The depositional feature of a glacier is __________.

  1. Beach

  2. Moraine

  3. Flood plain

  4. None of these

B Correct answer
Explanation

Moraines are ridge-like depositional features of glacial tills. They are long but narrow ridge with height more 30 meters. Moraines are consist of rock materials of heterogeneous shapes and size.

The soil is formed by the breaking down of rocks by the action of _____.

  1. wind

  2. water

  3. climate

  4. all of these
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The soil is formed by breaking down of rocks by an action of wind, water and climates like thawing of water that seeped through rock and climatic changes such as weathering of rocks, landslides also causes breaking of big rocks. This is how soil is formed by all these natural processes.
