Question 1

Question 5Explain two causes of pollution of water bodies with examples.

Accepted Answer

Two causes of pollution of water bodies are:Urbanisation — Rapid urbanisation in India during the recent decades has given rise to a number of environmental problems such as water supply, waste water generation and its collection, treatment and disposal. For example, pollution in major rivers.Oil spills — Waste oil from city drains, tankers and leakage from oil wells cause the oil to seep into the sea and pollute water. Massive oil spills at sea by huge oil tankers severely pollute the oceans.

Question 2

Question 1With the help of a diagram, explain the hydrological cycle.

Accepted Answer

Diagram showing the the hydrological cycle is given below:Most of the world's water is being recycled by this continuous process called the hydrological cycle or the water cycle.The Sun heats up the water bodies. The water evaporates as water vapour, which being light in weight, rises in the air.On reaching the higher, colder levels of the atmosphere, it cools and condenses into tiny water droplets that join to form clouds.When the clouds become too heavy and cannot remain suspended in the air, it comes down as precipitation such as rain or snow. Rain is the biggest source of fresh water on the Earth.Some of the rainwater seeps underground, some fills up depressions to form lakes, while others just flow into rivers and streams, which carry water to the oceans.The cycle is then repeated.

Question 3

Question 6How are canyons formed?

Accepted Answer

Canyons are deep, narrow valleys with steep sides formed by rivers cutting through hard rock over a long period of time. When a river is young and flows quickly through mountains, it erodes the land vertically, creating deep V-shaped valleys called canyons or gorges. Example: The Grand Canyon in the USA, carved by the Colorado River.

Question 4

Question 7Explain the formation of flood plains.

Accepted Answer

During monsoon, rivers often overflow their banks and flood the surrounding land. As the floodwater recedes, it leaves behind layers of fine, rich silt. Over time, these deposits build up to form flat and fertile areas called flood plains, ideal for farming.

Question 5

Question 8How are meanders formed?

Accepted Answer

As the river comes out of the mountains, it enters the flat, levelled plains where its speed is no more as rapid as before. This is called the middle course. Now, the river swings from bend to bend forming loops known as meanders.

Question 6

Question 9Mention two characteristics of a river in its lower course.

Accepted Answer

Two characteristics of a river in its lower course are as follows:The river becomes very slow and begins to deposit silt and sand in between the course of its flow. This sometimes leads to the formation of permanent river islands.The river forms a delta, or sometimes an estuary, where it meets the sea.

Question 7

Question 10Give two reasons why rivers are valuable to the farmers.

Accepted Answer

Rivers are valuable to farmers because:They bring fresh silt to make fertile plains, which are excellent for growing crops.The water of rivers is used to irrigate agricultural fields.

Question 8

Question 11Explain how human activities are degrading water bodies all over the globe.

Accepted Answer

Water bodies are fast degenerating, primarily due to human activities. Some of which are enumerated below:Household wastes — Domestic waste water is mixed with other wastes such as plastic, detergent, animal dung and human excreta and is together known as municipal waste. This pollutes water bodies.Industrial wastes — Factories produce toxic wastes which when discharged into water bodies, pollute the water and cause irreparable harm to aquatic creatures.Agricultural wastes — Agricultural wastes mostly consist of fertilisers and pesticides. They may be carried off from the farms to the rivers and lakes as surface runoff during rains or floods. They pollute the aquatic ecosystem by promoting rapid growth of algae and subsequent depletion of oxygen in water.Oil spills — Crude oil is transported across oceans in tankers. Accidents and leakages often cause oil spills that damage the marine ecosystems. Offshore drilling operations also contribute to oil spill.

Question 9

Question 3Why is a water crisis in the world even though most parts of the Earth is covered with water?

Accepted Answer

The water crisis in the world is due to the following reasons:Abundance of Salt Water — About 71% of the Earth's surface is covered with water, but 96.5% of it is saline and found in oceans and seas, which is not suitable for drinking or irrigation.Limited Freshwater Availability — Only about 3.5% of the Earth’s water is freshwater. However, most of this is not easily accessible:Frozen in glaciers, ice caps (Arctic, Antarctic)Stored underground in deep aquifersTiny Share for Direct Use — Just 0.5% of freshwater is found in rivers, lakes, and ponds, which is the primary source for all human, plant, and animal needs.Pollution by Human Activities — Many freshwater sources are being polluted by industrial waste, sewage, agricultural runoff, and plastics, making the water unsafe and reducing the usable supply.Overuse and Waste — Water is often wasted through careless usage, leaking pipelines, over-irrigation, and excessive extraction from rivers and underground sources, especially in urban and agricultural areas.Unequal Distribution — Freshwater is unevenly distributed across the world. Some regions face scarcity while others have relatively abundant resources.Thus, despite the Earth's water-rich appearance, the actual usable freshwater is extremely limited. Human pollution and wasteful practices are making the situation worse, leading to a growing global water crisis.

Question 10

Question 4Have you heard the term voyagers? Since olden times voyagers have ventured into faraway lands for explorations. Many a time they discovered new lands. Name any three famous explorers and write briefly about them under the following headings:Name :the country she/he belonged to :the expedition which made her/him famous :the year in which it was done :the discord that followed (if any) :any landmark named after her/him :

Accepted Answer

Question 11

Question 5Picture-based QuestionsIdentify the feature shown in the picture.In which course of a river does it form?What is the speed of the river during this course?Name another river feature formed during this course of the river.

Accepted Answer

The picture shows a canyon, specifically the Grand Canyon formed by river Colorado in Arizona.Canyons are formed in the upper course of a river.The river flows with great speed in its upper course due to the steep slope.Another river feature formed during the upper course is a waterfall.
