Question 30.
Define the following terms :
(a) Ox-bow lake
(b) Levees
(c) Meanders
Answer:
(a) Ox-bow lake – When a river enters the plain, it forms a large bend which is cut-off from the mainstream in due course of time. The cut-off stream takes the form of a lake called ox-bow lake.

(b) Levees – During flood, a river deposits sediments along its banks. Thus the banks rise. The raised banks are called levees.

(c) Meanders – When a river enters the plain, it twists and turns forming large bends. These bends are called meanders.

Question 31.

Answer:
(a) Waterfall – When the river tumbles at a steep angle over very hard rocks or down a steep valley side, it forms a waterfall.

(b) Floodplains – When a river outflows its banks, it causes floods in the neighbouring areas. The flood water takes away fine soil and other materials and deposits them in layers along the banks. This deposition leads to the formation of a flat fertile land called floodplain.

(c) Delta – When a river reaches the sea, it breaks into many streams and also its speed slows down. These streams are called distributaries having their own mouths. The sediment from all the mouths form a delta.

Question 32.

• Sea beaches.

Question 34.
How are sea caves formed?
Answer:
Strong sea waves continuously strike the nearby rocks and cause them to crack. In course of time, these cracks in the rocks widen and become larger giving rise to hollow-like caves. These caves are called sea caves.

Question 35.
When are sea arches formed?
Answer:
When the hollows, i.e., sea caves become bigger and bigger, only their roof remains. These structures are called sea arches.

Question 36.
What do you mean by ‘stacks’?
Answer:
When the roof of a sea cave is eroded by continuous erosion, only walls are left. These wall-like features are called stacks.

Question 37.
Define sea cliff.
Answer:
The steep rocky coast rising almost vertically above seawater is called sea cliff.

Question 38.
When are beaches formed?
Answer:
Beaches are formed when sea waves deposit sediments along the seashores.

Question 39.
What are glaciers? How do they erode the landscape?
Answer:

• Glaciers are the rivers of ice.
• They erode the landscape by bulldozing soil and stones to expose the solid rocks below.

Question 40.
How do glaciers form mountain lakes?
Answer:
Glaciers create deep hollow in the solid rocks. When ice melts, the hollow is filled up with water giving rise to mountain lakes.

Question 44.
Where do you find sand dunes? How are they formed?
Answer:

• Sand dunes are found in deserts.
• Winds lift and carry sand from one place to another in deserts. When winds stop blowing, sand falls and gets deposited in low hill-like structures called sand dunes.

Question 45.
What are loess? Where are large deposits of loess found?

Distinguish between high tide and low tide.
Answer:

High tide	Low tide
When water covers much of the shore by rising to its highest level, it is called high tide.	When water falls to its lowest level and recedes from the shore, it is called low tide.

Question 19.

Answer:
The strong gravitational pull exerted by the sun and the moon on the earth’s surface causes the tides.

Question 20.
Why do high tides occur?
Answer:
The water of the earth closer to the moon gets pulled under the influence of the moon’s gravitational force and causes high tide.

Answer:
Low magnitude tides are called neap tides. These tides occur when the moon is in its first and last quarter, and the ocean water get drawn in mutually perpendicular directions by the gravitational pull of the sun and the earth resulting in low tides.

Question 26.
Where do the warm and cold ocean currents originate?
Answer:

• The warm ocean currents originate near the equator and move towards the poles.
• The cold currents originate near-polar or higher latitudes and move towards tropical or lower latitudes.

• The areas where the warm and cold currents meet provide the best fishing grounds of the world.
• The areas where warm and cold currents meet also experience foggy weather making it difficult to navigate.

Question 28.
How are tides helpful to us?
Answer:

• High tides raise the water level at the shores. This helps the ships to arrive at the harbour more easily.
• During high tide, fish come closer to the shore. Thus, it helps in fishing.
• The rise and fall of water due to tides is being used to generate electricity in some places.

Question 29.
Explain the cause of Tsunami which occurred on 26th December 2004.
Answer:

• The Tsunami occurred due to an earthquake on 26th December 2004.
• As the Indian plate went under the Burma plate, there was a sudden movement of the seafloor, causing the earthquake.
• The ocean floor was displaced and tilted in a downward direction.
• A huge mass of ocean water flowed to fill in the gap that was being created by the displacement.
• This marked the withdrawal of the water mass from the coastlines of the landmasses in the south and southeast Asia.
• After thrusting of the Indian plate below the Burma plate, the water mass rushed back towards the coastline. This Tsunami travelled at a speed of about 800 km per hour.
