Geomorphic Processes Questions

Multiple choice

This can carve out great U-shaped valleys

  1. Lakes

  2. Cold Rock

  3. Iceberg

  4. Glacier
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Glaciers are large masses of ice that move slowly over land, carving out U-shaped valleys through the process of glacial erosion.

Multiple choice

This rock was broken by frost wedging, an example of...

  1. Lithification

  2. Deposition

  3. Weathering

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

Frost wedging is a physical process where water freezes in cracks, expands, and breaks the rock apart. This is a primary mechanism of mechanical weathering.

Multiple choice geography biosphere and landscape introduction to earth's landform development of landforms major landforms of the earth

Mountain-building word originates from greek term _______________.

  1. genic

  2. orogenic

  3. genetic

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

Orogeny refers to forces and events leading to a large structural deformation of the Earth's lithosphere (crust and uppermost mantle) due to the interaction between tectonic plates.

Orogeny is the primary mechanism by which mountains are built on continents. The word orogeny comes from Ancient Greek means building mountains.

Multiple choice geography biosphere and landscape introduction to earth's landform development of landforms major landforms of the earth

_________ is the cause for land form development.

  1. Internal pressure

  2. External pressure

  3. Both a and b

  4. Earth movement
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Earth’s Movement is the prime factors controlling Land Form Development. Landform, whether large or small result from the interaction of certain forces, they accomplish their work by various means of processes, which may be described as geologic, Climatic and biologic and these processes bring about the changes in the Earth’s surface which may be classified as

(I) Long Period Changes (Man Is unable to notice this change)

(II) short period Changes.

Multiple choice geography biosphere and landscape introduction to earth's landform development of landforms major landforms of the earth

Steep-walled valleys having narrow depressions and are cut by streams and rivers are called ______.

  1. waterfalls

  2. rift valley

  3. V-shaped valley

  4. U-shaped valley
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

In the youthful stage of fluvial cycle of erosion V-shaped valley are formed. It is steep-walled valley having narrow depression. Both the valley sides meet together at valley floor and water always touches the valley. V-shaped valleys are the result of accelerated rate of downcutting of river.

Multiple choice geography our changing earth glacier glaciers landforms created by glacial erosion

Long sinuous ridges found in former glacial sites in the direction of ice melted water streams are known as ________.

  1. Eskers

  2. Fjords

  3. Erratics

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

Long sinous ridges found in former glacial sites in the direction of ice melted water strems are known as Eskers.

An esker, eskar, eschar, or os, sometimes called an asar, osar, or serpent kame, is a long, winding ridge of stratified sand and gravel, examples of which occur in glaciated and formerly glaciated regions of Europe and North America.

Multiple choice geography our changing earth glacier glaciers landforms created by glacial erosion

Drowned glaciated valleys in high latitude regions are known as _______.

  1. Fjords

  2. Ocean ridges

  3. Sub-marine canyons

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

Drowned glaciated valleys in high latitude regions are known as Fjords.
Fjords are found in locations where current or past glaciation extended below current sea level. A fjord is formed when a glacier retreats, after carving its typical U-shaped valley, and the sea fills the resulting valley floor.

Multiple choice geography our changing earth glacier glaciers landforms created by glacial erosion

The important depositional landform produced by glaciers is __________.

  1. Flood plants

  2. Moraines

  3. Barchans

  4. Inselberg
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

When the glaciers melt or recede they deposit the rock materials brought by them in heaps of various shapes and sizes. These are known as moraines. Moraine is a ridge-like depositional feature of a glacier. They are long but narrow ridges with height more than 30m.

Multiple choice geography our changing earth glacier glaciers landforms created by glacial erosion

Which is not a type of moraine?

  1. Ground moraine.

  2. Lateral moraine.

  3. Crater moraine.

  4. All are the types of moraine
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

A mass of rocks and other sediments carried down and deposited by a glacier, typically as ridges at its edge or extremity is called a morain.

Different types of moraine:

  • Terminal moraines are found at the terminus or the furthest (end) point reached by a glacier.
  • Lateral moraines are found deposited along the sides of the glacier.
  • Medial moraines are found at the junction between two glaciers.
  • Ground moraines are disorganized piles of rocks of various shapes, sizes and of differing rock types.

Multiple choice evs soil- our life horizons of soil soil - formation and profile soil-nature

Weathering is the process of

  1. Formation of rock

  2. Formation of soil

  3. Formation of humus

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

Weathering is the breakdown of rocks, minerals, and soils through contact with the atmosphere, water, and biological organisms, which is the first step in soil formation.

Multiple choice soil as a natural resource natural resources - air, water and land land physical resources biology

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

  1. Wind

  2. Water

  3. Climate

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

The soil is formed by weathering, it is the process of breaking down of rocks by the action of heavy wind, water flow and climate. Breaking down of small particles of rocks mix with humus, make it soil fertile. Thus, the correct option is D.
