The Earth in the Solar System
• If we look at sky in the night it seems to be filled with tiny shining objects-some are bright, others are dim. They seem to be twinkling.
• Once in a month, we see full moon night of a fortnight later, you cannot see it at all. It is a new moon night or ‘Amavasya’.
• The sun, moon, stars and planets and all those objects shining in the night are called celestial bodies.
• Some celestial bodies are very big and hot. They are made of gas, have their own heat and light. They emit in large amounts. These celestial bodies are called stars. The sun is a star.
• While watching the night sky, we notice various patterns formed by different groups of stars. These are called constellations. Ursa Major is one such constellation.
• In ancient times, people used to determine directions during the night with the help of stars. The North star indicates the north direction. It is also called pole star.
• Some celestial bodies do not have their own heat and light. They are lit by the light of the stars. Such bodies are called planets.
• The Solar System:
The sun, eight planets, satellites and some other celestial bodies known as asteroids and meteoroids form the solar system.
• The Sun:
(i) The sun is the centre of solar system.
(ii) It is huge and made up of extremely hot gases.
(iii) The sun is the ultimate souce of heat and light for the solar system.
(i) The word ‘planet’ comes from the Greek word ‘Planetai’ which means wanderers.
(ii) There are eight planets in our solar system-Mercury, Venus, Earth, Mars, Jupiter,
Saturn, Uranus and Neptune.
(iii) All the eight planets of the solar system move around the sun in fixed paths. These
paths are elongated. They are called orbits.
(iv) Till August 2006, Pluto was also a planet. But now it is called only a celestial body.
• The Earth:
(i) The earth is the third nearest planet to the sun and is our home.
(ii) It is slightly flattered at the poles. That is why, its shape is called Geoid.
(iii) Conditions favourable to support life are probably found only on the earth.
(iv) From the outer space, the earth appears blue because its 2/3rds surface is covered by
water. It is, therefore, called a blue planet.
• The Moon:
(i) Our earth has only one natural satellite that is the moon.
(ii) It appears so big because it is nearer to our planet than other celestial bodies.
(iii) The moon moves around the earth in about 27 days and 8 hours.
(iv) The moon does not have conditions favourable for life.
(i) There are numerous tiny bodies which also move around the sun. These bodies are called asteroids.
(ii) They are found between the orbits of Mars and Jupiter.
(i) The small pieces of rocks which move around the sun are called meteoroids.
(ii) A galaxy is a huge system of billions of stars, and clouds of dust and gases. These are millions of such galaxies that make the universe.

Globe: Latitudes and Longitudes
• A globe is a true model of the earth.
• The globes are of varying sizes and types.
• Globe can be rotated in the same way as a top spin or potter’s wheel is rotated.
• Axis-The imaginary line passing through the centre of the earth and joining the two points.
• A needle is fixed through the globe in a titled manner, which is called its axis.
• Another imaginary circular line running on the globe divides it the earth into two equal parts.
This line is called as Equator.
• The northern half of the earth is known as the Northern Hemisphere and the southern half is
called the Southern Hemisphere.
• All parallel circles from the equator up to the poles are called parallels of latitudes.
• The equator represents the zero degree latitude.
• Besides the equator (0 degree celcius), the North Pole 90 degree North), the South Pole (90
degree South), there are four important parallels of latitude – Tropic of Cancer 23.5° south in the Southern Hemisphere, Arctic Circle at 66.5° north of the Equator and Antartic Circle at 66.6° south of the Equator.
• Heart Zones of the Earth
(i) The area which receives the maximum heat is called the Torrid zone.
(ii) The areas around Antarctic Circle in the Southern Hemisphere, have medium
temperature. These are called Temperature Zones.
(iii) These are certain cold areas in the hemisphere. They are called Frigid Zones.
• What are Longitudes:
(i) Unlike parallesl of latitude, all meridians are of equal length.
(ii) Hence, all countries decided that the count should begin from the meridian which
passed through Greenwich, where the British Royal Observatory is located. This
meridian is called the Prime Meridian.
• Longitude and Time:
(i) The best means of measuring time is by the movement of the earth, the moon and the planets.
(ii) The sun regularlgy rises and sets every day, and naturally. It is the best time-keeper
throughout the world.
(iii) Local time can be reckoned by the shadow cast by the sun, which is the shortest at noon and longest at sunrise and sunset.(iv) When the prime meridian of Greenwich has the sun at the highest point in the sky, all
the places along this meridian will have mid-day or noon.
(v) As the earth rotates from west to east, those places east of Greenwich will be ahead of
Greenwich time and those to the west will be behind it.
(vi) At any place a watch can be adjusted to read 12 0’clock when the sun is at the highest
point in the sky, when it is mid-day.
• Why do we have Standard Time?
(i) The local time of places which are on different meridians are bound to differ.
(ii) For example, in India there will be a difference of of about 1 hour and 45 minutes in
the local times of Dwarka in Gujarat and Dibrugarh in Assam.
(iii) In India, the longitude of 23.5° is treated as the standard meridian. The local time
at this meridian is taken as the standard time for the whole country. It is called Indian

Motions of the Earth
• The Earth has two types of motions namely, rotation and revolution.
• Rotation is the movement of the earth on its axis. Days and Nights take place because of
• Revolution is the movement of the earth around the Sun in a fixed path or orbit. Revolution
causes the change of seasons.
• The axis of the earth which is an imaginary line, has an angle of 66.5° with its orbital plane.
• The circle that divides the day from night on the globe is called the circle of illumination.
(i) The second motion of the earth around the sun in its orbit is called revolution.
(ii) It takes 365 days and 6 hours (one year) to revolve around the sun.
(iii) We consider a year as consisting of 365 days only and ignore six hours for the sake of
(iv) Six hours saved every year are likely to make one day (24 hours) over a span of four
(v) This surplus day is added to the month of February.
(vi) Every fourth year, February is of 29 days instead of 28 days. This year with 366 days
is called a leap year.
(vii) The earth goes around the sun in an elliptical orbit.
(viii) The nights are longer than the days in winter season. This position of the earth is
called as summer solstice.
(ix) On 22nd December the Tropic of Capricorn gets direct rays of the sun as the South
Pole tilts towards it. It is summer in Southern hemisphere and winter in Northern
hemisphere. This is called winter solstice.
(x) On 21st March and 23rd September, direct rays of the sun fall directly on the equator.
During this period, the whole earth experiences equal days and equal nights. This is
called an equinox.

• A map is a representation or a drawing of earth’s surface or part of it, drawn on a flat surface
according to a scale.
(i) Maps are of several types.
(ii) Maps showing natural features of the earth are called physical or relief maps.
(iii) Maps showing cities, town and villages, countries and states of the world with their
boundaries are called political maps.
(iv) Some maps focus on specific information like rainfall map, road maps, maps of tourist
places are called thematic maps.
• Components of Maps:
(i) There are three components of maps-distance, direction and symbol.
(ii) Distance is measured in terms of scale. Scale is the ration between the actual distance
on the ground and the distance shown on the map.
(iii) When large areas like contintents or countries are to be shown on a paper, then we
use a small scale.
(iv) When a small area like your village to town in to be shown on paper, then we use a
large scale map.
(v) Directions are cardinal points like North, South, East and West.
(vi) Symbols are certain letters, shades, colours, pictures and lines, which give us
information about a limited place.
(vii) Various other things like sketches and plan are used to draw an area of a large scale.
