The forces responsible for the formation of fold mountains:

The large scale uplift or subsidence of land:

The two forces, Orogenic and Epeirogenic that originate deep inside the earth:

The forces operating on the surface of the earth which cause formation of landforms are called ______.

Identify A and B.

Oceanic trenches in combination with volcanic mountain systems lead to the formation of ______.

Volcanic activities are common in which of the following?

Assertion (A): External forces or Exogenic forces are Destructive Forces.

Reason (R): They produce relief such as mountains, plateaus, plains, lakes and big faults.

Assertion (A): Residual mountains are also called mountains of denudation.

Reason (R): Denudation and erosion by natural agents cause mountains to be lowered.

Which amongst the following highlands are highly eroded by the agents of gradation and have gentler slopes, rounded tops and sculptured domes?

Mountains which are subjected to weathering and erosion for a long time are lowered down:

Which of the following is/are correctly matched?

Assertion (A): The forces of faulting lead to the formation of block mountains.

Reason (R): Block mountains are often separated by intervening basins called graben.

The Coromandel plains along the east coast of India were formed as a result of two different activities. Name them.

The plains that are formed by the deposition of materials which have been brought by various agents of transportation:

Depositional plains formed as a result of action of wind have irregular and undulating surface because of ______.

A piece of land reclaimed from the sea or lake:

The plains that are formed due to uplift or subsidence of land are called ______.

Which of the following pairs is incorrectly matched?

Epeirogenic forces lead to the formation of Block Mountains. In this context which of the following are true?

Name the plateaus, formed along with fold mountains, that are surrounded by hills and mountains on all sides.

Assertion (A): Many lakes exist in the vast lowland of the Great Plains of the USA.

Reason (R): The Great Plains were formed due to uplift of land submerged under water.

How are various landforms formed on the surface of the earth?

Describe the formation of mountains.

Describe the types of formation of mountains.

Give a geographical reason for the following:

The asthenosphere is in a semi-molten state.

Give a geographical reason for the following:

Exogenic forces are also called destructive forces.

Give a geographical reason for the following:

Draw a well labelled diagram to show the formation of a block mountain.

Describe the characteristics of two different types of plateaus.

Describe the characteristics of structural plains.

Give a reason for the following:

There are different types of plains.

Give a reason for the following:

Alluvial plains are regarded as the granaries of the world.

Give a reason for the following:

The landforms on the surface of the earth are symbols of the energy of the earth.

Explain the chief characteristics of depositional plains.

Explain the types of depositional plains.

Find out the landforms found in your state. How were these landforms formed? How many changes have come in these landforms over the years.

The earth releases its energy through tectonic activity, earthquakes and volcanoes. Imagine what will be the consequences if this energy remains trapped inside the earth. State these consequences with examples.

Draw and colour different relief features on the surface of the earth.

On an outline map of the world show major fold mountains, plateaus and plains with the help of symbols.
