OUR
CHANGING EARTH
(QUESTION
ANSWER)
NCERT EXERCISE
Q 1. Answer the following questions.
(i) Why do the plates
move?
Answer: The plates move due to the molten magma inside the Earth.
(i) What are exogenic and
endogenic forces?
Answer: The movement of the Earth is divided on the basis of the forces,
which cause them. So, the forces that act, in the interior of the earth are
called Endogenic forces and the forces that work on the surface of the earth
are called Exogenic forces.
(iii) What is erosion?
Answer: Erosion is defined as the wearing away of the landscape by
different agents like water, wind and ice. The process of erosion and
deposition creates different land-forms on the surface of the earth.
(iv) How are flood
plains formed?
Answer: When a river overflows its banks, it results in the flooding of
the area surrounding it. When it floods, it deposits a layer of fine soil and
other material called sediments. Thus, forming a fertile layer of soil called
flood plains.
(v) What are sand
dunes?
Answer: When the wind blows, it lifts and transports sand from one
place to another. When the wind stops blowing, the sand falls and gets
deposited in the low hill-like structures. These are called sand dunes. They
are mostly found in desert areas.
(vi) How are beaches
formed?
Answer: The sea waves deposit sediments along the seashores. This
results in the formation of beaches.
(vii) What are the
ox-bow lakes?
Answer: When the river enters the plains, it twists and turns forming large bends known as meanders. In due course of time, the meander loops start to cut off the river and form cut off lakes, known as the ox-bow lakes.
Q 2. Tick the correct
answer.
(i) Which is not an
erosional feature of sea waves?
(a) Cliff
(b) Beach
(c) Sea cave
Answer: b
(ii) The depositional
feature of a glacier is:
(a) Flood plain
(b) Beach
(c) Moraine
Answer: c
(iii) Which is caused
by the sudden movements of the earth?

4. Give reasons.
(i) Some rocks have the
shape of a mushroom.
Answer: Some rocks have a shape of a mushroom because, in deserts,
wind erodes the lower section of the rock more than the upper section which
makes the base of the rock narrow and the upper part wide, giving it the shape
of a mushroom.
(ii) Flood plains are
very fertile.
Answer: Flood plains are very fertile because at times when river
water overflows, it results in the flooding of the neighbouring areas. This
deposit a layer of fine soil and other sediments at the banks of the river,
which leads to fertile flood plains.
(iii) Sea caves are
turned into stacks.
Answer: When the cavities in the sea caves become bigger and bigger,
only the roof of the caves are leftover, which forms sea arches. Further, due
to erosion, the roof vanishes and only the walls stay intact, turning the sea
caves into stacks.
(iv) Buildings collapse
due to earthquakes.
Answer: When the lithospheric plates move, the surface of the earth
vibrates and then these vibrations travel outwards from the epicentre in the
form of waves, which leads to sudden movement and results in the collapse of
buildings.

Short Answer Type Questions
1. Mention the work of
ice.
Answer: Glaciers
are rivers of ice that erode the landscape by destroying soil and stones to
expose the solid rock below. Glaciers carve out deep hollows. As the ice melts
they get filled up with water and become beautiful lakes in the mountains. The
material carried by the glacier such as rocks big and small, sand and silt gets
deposited. These deposits form glacial moraines.
2. What is an
earthquake? What are some common earthquake prediction methods?
Answer: When
the lithospheric plates move, the surface of the earth vibrates. The vibrations
can travel all around the earth. These vibrations are called earthquakes. Some
common earthquake prediction methods include studying animal behaviour, fish in
the ponds get agitated, snakes come to the surface.
3. Give an account of earthquake preparedness.
Answer: Earthquake
is a natural calamity which we cannot stop. But we can minimise its impact if
we are prepared before-hand.
During an earthquake, we should shift to some safe spot. We should hide under a
kitchen counter, table, or desk against an inside comer or wall. We should stay
away from fireplaces, areas around chimneys, windows that shelter including
mirrors and picture frames. Moreover, we should spread awareness amongst our
friends and family members.

1. What do you know about the
lithospheric plates?
Answer: The earth’s crust
consists of several large and some small, rigid, irregularly— shaped plates,
Le., slabs which cany continents and the ocean floor.
2. How do the lithospheric plates move?
Answer: They move
around very slowly, just a few millimetres each year.
3. What is a volcano?
Answer: A volcano is
a vent or opening in the earth’s crust through which molten material erupts
suddenly.
4. Define focus’ and ‘epicentre’.
Answer: The place in the
crust where the movement starts is called the ‘focus’. The place on the surface
above the focus is called the ‘epicentre’.

Short Answer Type Questions
1. Mention the work of
ice.
Answer: Glaciers
are rivers of ice that erode the landscape by destroying soil and stones to
expose the solid rock below. Glaciers carve out deep hollows. As the ice melts
they get filled up with water and become beautiful lakes in the mountains. The
material carried by the glacier such as rocks big and small, sand and silt gets
deposited. These deposits form glacial moraines.
2. What is an
earthquake? What are some common earthquake prediction methods?
Answer: When
the lithospheric plates move, the surface of the earth vibrates. The vibrations
can travel all around the earth. These vibrations are called earthquakes. Some
common earthquake prediction methods include studying animal behaviour, fish in
the ponds get agitated, snakes come to the surface.
3. Give an account of earthquake preparedness.
Answer: Earthquake
is a natural calamity which we cannot stop. But we can minimise its impact if
we are prepared before-hand.
During an earthquake, we should shift to some safe spot. We should hide under a
kitchen counter, table, or desk against an inside comer or wall. We should stay
away from fireplaces, areas around chimneys, windows that shelter including
mirrors and picture frames. Moreover, we should spread awareness amongst our

can travel all around the earth. These vibrations are called earthquakes. Some
common earthquake prediction methods include studying animal behaviour, fish in
the ponds get agitated, snakes come to the surface.
3. Give an account of earthquake preparedness.
Answer: Earthquake
is a natural calamity which we cannot stop. But we can minimise its impact if
we are prepared before-hand.
During an earthquake, we should shift to some safe spot. We should hide under a
kitchen counter, table, or desk against an inside comer or wall. We should stay
away from fireplaces, areas around chimneys, windows that shelter including
mirrors and picture frames. Moreover, we should spread awareness amongst our
friends and family members.

1. What do you know about the
lithospheric plates?
Answer: The earth’s crust
consists of several large and some small, rigid, irregularly— shaped plates,
Le., slabs which cany continents and the ocean floor.
2. How do the lithospheric plates move?
Answer: They move
around very slowly, just a few millimetres each year.
3. What is a volcano?
Answer: A volcano is
a vent or opening in the earth’s crust through which molten material erupts
suddenly.
4. Define focus’ and ‘epicentre’.
Answer: The place in the
crust where the movement starts is called the ‘focus’. The place on the surface
above the focus is called the ‘epicentre’.

Short Answer Type Questions
1. Mention the work of
ice.
Answer: Glaciers
are rivers of ice that erode the landscape by destroying soil and stones to
expose the solid rock below. Glaciers carve out deep hollows. As the ice melts
they get filled up with water and become beautiful lakes in the mountains. The
material carried by the glacier such as rocks big and small, sand and silt gets
deposited. These deposits form glacial moraines.
2. What is an
earthquake? What are some common earthquake prediction methods?
Answer: When
the lithospheric plates move, the surface of the earth vibrates. The vibrations
can travel all around the earth. These vibrations are called earthquakes. Some
common earthquake prediction methods include studying animal behaviour, fish in
the ponds get agitated, snakes come to the surface.
3. Give an account of earthquake preparedness.
Answer: Earthquake
is a natural calamity which we cannot stop. But we can minimise its impact if
we are prepared before-hand.
During an earthquake, we should shift to some safe spot. We should hide under a
kitchen counter, table, or desk against an inside comer or wall. We should stay

Very Short Answer Type Questions
1. What do you know about the
lithospheric plates?
Answer: The earth’s crust
consists of several large and some small, rigid, irregularly— shaped plates,
Le., slabs which cany continents and the ocean floor.
2. How do the lithospheric plates move?
Answer: They move
around very slowly, just a few millimetres each year.
3. What is a volcano?
Answer: A volcano is
a vent or opening in the earth’s crust through which molten material erupts
suddenly.
4. Define focus’ and ‘epicentre’.
Answer: The place in the
crust where the movement starts is called the ‘focus’. The place on the surface
above the focus is called the ‘epicentre’.
5. Name the three types of
earthquake waves.
Answer: P waves or longitudinal
waves
S waves or
transverse waves
L wave or surface waves.
6. What is a seismograph? [V. Imp.]

9. Where is Victoria Falls located?
[Imp.]
Answer: Victoria Falls is
located on the borders of Zambia and Zimbabwe in Africa.
10. What is delta?
Answer: The collection of
sediments from all the mouths forms a delta. It is a triangular-shaped
landmass.
11. Name some coastal landforms.
Answer: Sea caves,
sea arches, stacks, and sea cliffs.
12. How are glacial moraines
formed?
Answer: The material
carried by the glacier such as rocks big and small, sand and silt gets
deposited. These deposits form glacial moraines.
13. Name the two processes which wear
away the landscape.
Answer: Weathering and
erosion.
14. What does the process of erosion and
deposition create?
Answer: The process of
erosion and deposition create different landforms on the surface of the earth.
15. Name a few rivers of the world that
form a delta?
Answer: Nile, Zaire, Ganga-Brahmaputra,
Hwangotto, Murray-Darling, Amazon, etc.
Short Answer Type Questions
1. Mention the work of
ice.
Answer: Glaciers
are rivers of ice that erode the landscape by destroying soil and stones to
expose the solid rock below. Glaciers carve out deep hollows. As the ice melts
they get filled up with water and become beautiful lakes in the mountains. The
material carried by the glacier such as rocks big and small, sand and silt gets
deposited. These deposits form glacial moraines.
2. What is an
earthquake? What are some common earthquake prediction methods?
Answer: When
the lithospheric plates move, the surface of the earth vibrates. The vibrations
can travel all around the earth. These vibrations are called earthquakes. Some
common earthquake prediction methods include studying animal behaviour, fish in
the ponds get agitated, snakes come to the surface.
3. Give an account of earthquake preparedness.
Answer: Earthquake
is a natural calamity which we cannot stop. But we can minimise its impact if
we are prepared before-hand.
During an earthquake, we should shift to some safe spot. We should hide under a
kitchen counter, table, or desk against an inside comer or wall. We should stay
away from fireplaces, areas around chimneys, windows that shelter including
mirrors and picture frames. Moreover, we should spread awareness amongst our
friends and family members.
2. We find thorny bushes in deserts.
3. Grasslands are grown in the regions of moderate rainfall.
4. Silver fox and polar bear are common animals of coniferous
region.
5. The other name for coniferous forest is Tundra.
