  • The migration of male workers in search of jobs decreases the independent population of the source regions which increases the dependency ratio.

b) Social consequences:

  • The migration of people from different regions towards an urban area leads to the formation of a plural society.
  • It helps the people to come out of narrow mindedness and people become generous.

c) Economic consequences:

  • The migration of more people from overpopulated to underpopulated regions results in the imbalance of the resource-population ratio.
  • In some cases, the regions of over and under population may become the regions of optimum population.
  • Migration may influence the occupational structure of the population of an area.
  • Through this, it will certainly affect the economy of the regions also.
  • Brain drain is a consequence of migration.
  • Brain drain refers to the migration in which skilled people from economically backward countries move to developed countries in search of better opportunities
  • Eventually, this leads to backwardness in source regions. This is called a “backwash effect”.

d) Environmental consequences:

  • Large scale movement of people from rural to urban areas causes overcrowding in cities and puts heavy pressure on resources.
  • It leads to the rapid growth of cities.
  • The overpopulation in urban areas leads to the pollution of air, water, and soil.
  • Scarcity of drinking water, lack of space for housing, traffic congestion, and poor drainage are the common environmental problems that prevail in urban areas.
  • The lack of space for housing and the rising land cost lead to the formation of slums.

3. The sub-surface runoff is usually referred to as interflow.
Answer:
True

VI. Answer in brief:
1. Write a short note on the aquifer.
Answer:
An aquifer is an underground layer of water-bearing rock.

2. Define “ hydrological cycle”.
Answer:
The hydrological cycle is a global sun-driven process where water is transported from oceans to the atmosphere, from the atmosphere to land, and from land back to oceans

3. How is the dew formation takes place?
Answer:
Dew is a water droplet formed by the condensation of water vapour on a relatively cold surface of an object. It forms when the temperature of an object drops below the dew point temperature.

4. Write a short note on surface run-off.
Answer:
Surface Runoff is the portion of rainfall, which enters the stream immediately after the rainfall. It occurs when the rainfall is longer, heavier, and exceeds the rate of infiltration. In this condition, the excess water makes a head over the ground surface, which tends to move from one place to another following land gradient and is known as overland flow. When the overland flow joins the streams, channels or oceans, it is termed as surface runoff or surface flow.

VII. Give reasons:
1. Infiltration of water is low in the region of non-porous soil.
Answer:
Because percolation moves the infiltrated water through the soil profile and rock layers to form groundwater.

2. Freshwater is less on the earth.
Answer:
Most of the water on the earth is saline and is found in seas and oceans, which constitutes about 97.2%.

3. Snowfall is common in the polar region and mountainous regions.
Answer:
Often water vapour in a cloud is converted directly into snow pieces due to lowering of temperature and so it is common in the polar and mountainous regions.

VIII. Answer in a paragraph:
1. Explain the different stages involved in the hydrological cycle.
Answer:
The three important phases of the hydrologic cycle are:

  • Evapotranspiration,
  • Precipitation and
  • Runoff.

1. Evapotranspiration:
It is defined as the total loss of water from the earth through evaporation from the surface water bodies and the transpiration from vegetation. In cropped areas, it is difficult to determine the evaporation and transpiration separately. Therefore it is collectively called evapotranspiration.

2. Precipitation:
It refers to all forms of water that fall from clouds and reaches the earth’s surface. For the occurrence of precipitation, cloud droplets or ice crystals must grow heavy enough to fall through the air. When the droplets grow large in size, they tend to all. While moving down, by collecting some small droplets, they become heavy enough to fall out of the cloud as raindrops.

3. Runoff:
Runoff is the water that is pulled by gravity across the land’s surface. It replenishes groundwater and surface water as it percolates into an aquifer (it is an underground layer of water-bearing rock) or moves into a river, stream, or watershed. It comes from unabsorbed water from rain, snowmelt, irrigation or other sources, comprising a significant element in the water cycle as well as the water supply when it drains into a watershed. Runoff is also a major contributor to erosion which carves out canyons, gorges, and related landforms.

2. Distinguish between evaporation and transpiration.

Water boils at 100°C temperature but, it actually begins to evaporate at 0°c. Much of the water taken up by the plants is released through transpiration.

Evaporation Transpiration
1. The process in which the liquid form of water changes into gaseous form. The process by which the water content in the plant are released into the atmosphere in the form of water vapour.
3. The amount of water gets evaporated is about the same as the amount of water delivered to earth as precipitaion. The soil water content and the ability of the soil to conduct water the roots and the nature of the plant parts also determine the transpiration rate.
4. The rate of evaporation is low during the periods of calm winds than during windy times. The rate of transpiration is affected by the temperature, wind and humidity.

3. Give a detailed explanation on different forms of precipitation.
The form of precipitation in a region depends on the kind of weather or the climate of the region. The Precipitation in the warmer parts of the world is always in the form of rain or drizzle.
In colder region, precipitation may fall as snow or ice.
Common types of precipitation include rain, sleet, freezing rain, hail & snow.

Rain:

  • The most common kind of precipitation is rain.
  • The precipitation in the form of water droplet is rain.
  • Below 0.5 mm in diameter is known as drizzle and above 0.5 mm in diameter is known as rain.

Sleet:
The precipitation which takes place in the form of a mixture of water droplets and tiny particles of ice is known as sleet.

Freezing Rain:

  • Raindrops falling through cold air near the ground do not freeze in the air.
  • Instead, the raindrops freeze when they touch a cold surface.
  • This is called freezing rain.

Hail:
The precipitation which consists of round pellets of ice which are larger than 5mm in diameter is called as hail or hailstones.
Snow:
The precipitation in form of a powdery mass of ice is known as snowfall which is common in the polar and high mountainous regions.

4. Explain the run-off and its types.

Runoff is the water that is pulled by gravity across the land’s surface. It replenishes groundwater and surface water as it percolates into an aquifer (it is an underground layer of water-bearing rock) or moves into a river, stream, or watershed.

Types of Runoff:
Based on the time interval between the instance of rainfall and generation of runoff, the runoff may be classified into the following three types

1. Surface Runoff:
It is the portion of rainfall, which enters the stream immediately after the rainfall. It occurs when the rainfall is longer, heavier, and exceeds the rate of infiltration. In this condition, the excess water makes a head over the ground surface, which tends to move from one place to another following a land gradient and is known as overland flow. When the overland flow joins the streams, channels, or oceans, it is termed as surface runoff or surface flow.

2. Sub – Surface Runoff:
The water that has entered the subsoil and moves laterally without joining the water-table to the streams, rivers or oceans is known as sub-surface runoff. The subsurface runoff is usually referred as interflow.

3. Base Flow:
It is a flow of underground water from a saturated groundwater zone to a water channel. It usually appears at a downstream location where the channel elevation is lower than the groundwater table. Groundwater provides the streamflow during dry periods of small or no precipitation.

VIII. Answer in a paragraph:

1. Water on the Earth – Explain.
Answer:

  • About 71 % of the earth’s surface is covered by water.
  • The quantity of water present on the earth is about 326 million cubic miles.
  • It is hard to visualise this massive quantity of water.
  • Most of the water on the earth is saline and is found in seas and oceans.
  • The salt water constitutes about 97.2% and the fresh water is only about 2.8%.
  • Out of this 2.8%, about 2.2% is available as surface water and the remaining 0.6% is groundwater. From this 2.2% of surface water, 2.15% is available in the form of glaciers and icecaps, 0.01% in lakes and streams and the remaining 0.04% is in other forms.
  • Only about 0.25% of the total ground water of 0.6% can be economically extracted with the present drilling technology.

2. Explain the forms of condensation.
Answer:
Dew, fog, and Clouds are the three major forms of condensation.

  • Dew: It is a water droplet formed by the condensation of water vapour on a relatively cold surface of an object.
  • Frost: The ice crystals formed by the deposition of water vapour on a relatively cold surface of an object is known as frost.
  • Fog: Fog is the suspended tiny water droplets or ice crystals in an air layer next to the earth’s surface.
  • Mist: Mist is the tiny droplets of water hanging in the air.
  • Clouds: Clouds consist of tiny water droplets/ice particles which are so small and light in weight.
