CHAPTER – 3 (WEATHER AND CLIMATE)

Weather is an ever changing phenomenon of our environment. Human life on earth is

influenced more by weather than any other phenomenon of the physical environment.

Today the newspapers, radio and television report a wide range of weather events

regularly. They also provide information about the weather conditions likely to occur

during the coming days. For thousands of years scientists have tried to predict the

weather. The study of weather and its elements is known as meteorology.

WEATHER AND CLIMATE

Weather keeps changing from hour to hour and from day to day. Weather can

be defined as the atmospheric conditions at a given place and at a given time.

The climate on the other hand, can be defined as the sum of the weather

conditions of a large area over a long period. It is thus the average weather as

well as the variations and extremes of an area.

THE ELEMENTS OF WEATHER AND CLIMATE

Temperature, atmospheric pressure, humidity, precipitation, winds, clouds etc.

are some of the important elements of weather.

TEMPERATURE:

Temperature affects all the major elements of weather including air pressure,

cloud formation, humidity and precipitation. The difference in temperature is

associated with the formation of heat zones and pressure belts.

HOW THE EARTH AND ITS ATMOSPHERE GET HEATED?

The only permanent and continuous source of heat on the planet, earth is the

sun. The sun constantly radiates heat and light in all directions. This process of

giving out energy by the sun is called as the solar radiation.

1. Insolation: The amount of solar radiation received on the earth's surface is

called insolation.

2. Terrestrial Radiation: Solar radiation is in the form of short waves and it

reaches the earth's surface without heating the atmosphere. Most of this heat

energy is reflected back by the earth's surface in the form of long-wave

radiations known as the terrestrial radiation. The atmosphere is thus heated

indirectly through the earth. The amount of insolation received on various parts

of the earth is not equal. It varies from place to place and depends on-

LATITUDE: The latitude at which a place is located affects the temperature of the

place. The region near the Equator gets more direct rays of the Sun. The direct rays

are concentrated over a smaller area and so they heat up the Earth more. As we

move away from the Equator, due to the curvature, the Sun's rays strike the Earth

at an angle. The slanting rays of the Sun spread the heat over a larger area and so

do not heat to the same extent as the direct rays. Thus, the temperature decreases as

the distance increases from the Equator.

ISOTHERMS: The distribution of air temperature is often shown on a map by

isotherms, these are the lines drawn to connect locations having the same

temperature. Each line connects points having the same temperature.

ISOTHERMS

ATMOSPHERIC PRESSURE

The force exerted by the vertical column of air per unit of area is called

atmospheric pressure. Atmosphere surrounding the earth is held to it due to

gravity. Therefore, the air has weight and it exerts a force on the earth's surface.

FACTORS AFFECTING ATMOSPHERIC PRESSURE:

1. Altitude: The pressure exerted by the atmosphere decreases with height or

altitude. The atmospheric pressure is highest at sea level. This is because at great

heights the air is thinner or less dense than the air at the sea level.

2. Temperature: Atmospheric pressure decreases with increase in temperature.

This is because when the temperature rises, air expands. The molecules of air

move far apart (become less dense) and hence exert less pressure.

WORLD'S PRESSURE BELTS

The unequal heating of the earth and its atmosphere, and the rotation of the

earth are the two main factors which are responsible for the formation of

pressure belts of the world. There are following permanent pressure belts:

Equatorial Low Pressure Belt

Sub-Tropical High Pressure Belt

Sub-Polar Low Pressure Belt

Polar High Pressure Belt

PRESSURE BELTS OF THE WORLD

1. Define – a) Meteorology b) Insolation c) Atmospheric pressure

d) Isotherms.

2. Name any two elements of weather and climate.

3. Name any two factors affecting atmospheric pressure.

4. Name any two factors which are responsible for the formation of pressure

belts of the world.

5. Temperature is an important element of weather and climate. Justify.

6. Distinguish between weather and climate.

Rise of Islam

Q1. Answer the following questions in one or two sentences:

1. Muhammad was forced to leave Mecca as some of his teachings went

against the established faith of the Arabs. So, in AD 622, he took refuge in

a town called Medina (the city of prophet). This escape of Muhammad is

called Hijrah. This escape is significant as it is marked as the beginning of

the Islamic era and the birth of Muslim community, or ummah

2. The two sects into which Islam split were Shia and Sunni. Shias

regarded Ali as the prophet‟s true successor. They believe that a caliph is appointed by divine will; whereas Sunnis believed that a caliph should be

chosen by the whole community.

3. Islam stresses on the equality, brotherhood and the responsibility of

every man to live a life of faith without the help of priests. Hence, there is

no clergy.

4. The two most powerful caliphates are Umayyids of Damascus and, the

Abbasids of Baghdad.

Q2. Fill in the blanks:

1. There were succession disputes during the tenures of the caliphs

Uthman and Ali.

2. Prophet Muhammad continued to worship the black stone at the

Kaaba

3. Ramzaan is the month in which Muslims fast from dawn to dusk.

CHAPTER-2: FRACTIONS AND DECIMALS

TOPIC:DECIMALS

(i) Jhon has Rs. 15.50 and Salma has Rs. 15.75. Who has more money? To find this

we need to compare the decimal numbers 15.50 and 15.75. To do this, we first compare

the digits on the left of the decimal point, starting from the leftmost digit. Here both the

digits 1 and 5, to the left of the decimal point are same. So we compare the digits on the

right of the decimal point starting from the tenth place. We find that 5 ˂ 7, so we say 15.50 ˂ 15.75. Thus, Salma has more money than Jhon.

If the digits at the tenth place are also same then compare the digits at the

hundredths place and so on.

(ii) While converting lower units of money, length and weight, to their higher units,

we are required to use decimals. For example, 3 paise = Rs 3

100 = Rs. 0.003, 5g =

5

1000 kg

= 0.0005 kg, 7 cm = 7

100 m = 0.07m

(iii) In addition and subtraction of decimal numbers, first convert the decimal numbers

into like decimals.

(iv) While multiplying the decimal number, the numbers are multiplied without

decimals. Then put the decimal in the product. The number of digits after which decimal

is to be placed is obtained by adding the number of digits to the right of the decimal

points in the decimal numbers that are being multiplied.

While multiplying 2.5 and 1.25, you will first multiply 25 × 125 = 3225. For

placing the decimal in the product obtained you will count 1 + 2 = 3 (number of digits

after the decimal in both the decimal numbers). Thus, 2.5 × 1.25 = 3.225.

(v) While dividing the decimal number, the numbers are divided without decimals.

Then put the decimal in the quotient.

While dividing 6.4 ÷ 2, you will first divided 64 ÷ 2 = 32. For placing the decimal,

there is one digit to the right of the decimal point in 6.4. Place the decimal in 32 such that

there would be one digit to its right. Thus we get 3.2.

Practice Worksheet

1. Write the following decimal numbers in the expanded form:-

(i) 20.03 (ii) 3.045

2. Write the place value of 2 in the following decimal number:-

(i) 2.56 (ii) 9.42

3. Express in Kg:

(i) 200g (ii) 3470g

4. Arrange the following decimal numbers in ascending order:

0.370, 0.25, 0.42, 0.352, 0.516

5. Find:

(i) 211.02 × 4 (ii) 2.5 × 0.3 (iii) 0.2 × 316.8

6. Find:

(i) 651.2 ÷ 4 (ii) 52.5 ÷ 10 (iii) 0.78 ÷ 100 (iv) 7.9 ÷ 1000

7. Find the area of a rectangle whose length is 5.7cm and breadth 3cm.

8. How much less is 28 km than 42.6 km?
