Basin: The area of land through which a river flows, making it to be lower than the surrounding land. For example Ganga basin, Chambal basin, Mahanadi basin etc.

Delta and Estuary

Estuary and Delta - important Geographical terms

                   Estuary and Delta

Delta: A triangular piece of fertile land formed by a river before falling into the sea. It is formed only when the river is dead slow. World’s largest delta is the Sunderban delta formed by river Ganga and Brahmaputra.

Estuary: An area where the fresh water from a river meets the sea or ocean at comparatively high speed. It is funnel shaped. Towards the sea it is wide open. In India both Narmada and Tapi rivers form an estuary before falling into the Arabian sea. DELTA AND ESTUARY.

Moreover, an estuary is just the opposite of delta.

Bay and Gulf

Bay: A small body of water which is wide open from one side and enclosed partially by land. For example, Bay of Bengal in India and Hudson Bay in Canada.

Gulf: A gulf is a place where the sea enters deep into the land. They are enclosed by land from three sides. For example Gulf of Kutchch and Gulf of Cambay in Gujarat.

60 Geographical Terms For Students

Strait: A narrow passage of water connecting two other two large water bodies. For example India and Sri Lanka are separated by a narrow water body which connects Bay of Bengal and Indian Ocean. Name of the strait is Palk Strait.

Isthmus: A narrow strip of land that connects two big landmasses and also separates two water bodies. The best example of an Isthmus is Panama Isthmus which connects North America with South America. Also separates Pacific ocean with Atlantic ocean.

Sea and Ocean

Sea: A huge low lying area filled with salty water. Example Arabian sea, Caspian sea, Mediterranean sea.

Ocean: When two or more sea meet they form an ocean. It is generally a very large salt water body. Bay of Bengal sea and Arabian sea meet to form Indian ocean.

Lake, Lagoon and Oasis

Lake: A lake is usually a depression or a low area which is filled with water. It can be a salt water lake like sambhar lake in Rajasthan. It can be a fresh water lake also like lake Superior. Most of the lakes contain saline water.

Stalagmite: It is also formed by the mineral mixed water dripping on the floor. It rises from the floor.

Magma and Lava:

Magma: Molten rock inside the earth if called Magma.

Lava: When molten rocks come out on to the earth’s surface, it is called Lava  “हमारी पृथ्वी के अंदर” .

Igneous, Sedimentary and Metamorphic rocks:

Igneous rocks: Rocks which are formed by the cooling of lava are called Igneous rocks. They are also known as primary rocks. These rocks are made from fine grains and are usually very hard. Example is Basalt.

Sedimentary rocks: Rocks formed by the deposition of sediments are called Sedimentary rocks. These rocks are soft and many different colour of layers are visible. Himalayas are made up of Sedimentary rocks. Example is sandstone.

Metamorphic rocks: when Igneous and Sedimentary rocks go under the earth because of earthquake or volcano,  their original form changes due to high temperature and pressure. Thus, get converted into Metamorphic rocks. For example Limestone under high temperature and pressure changes into marble INSIDE OUR EARTH .

Tropic of Cancer and Tropic of Capricorn:

Tropic of Cancer is the latitude which makes an angle of 23 and 1/2 degrees North from the center of the earth. It divides India into almost two equal parts. On 21st of June, sunrays falls directly on this latitude all over in the Northern Hemisphere.

Tropic of Capricorn is the latitude which makes an angle of 23 and 1/2 degrees South from the center of the earth. Therefore, on 21st of December, sunrays falls directly on this latitude all over in the Southern Hemisphere. Do you know that Australians celebrate Christmas during summer season.

Waves and Tides:

Waves are the rising and falling of water in the sea. It is caused by wind. The strength of wave is determined by the speed of wind. However, during a full moon day, the waves rise very high in the sea.

Tides are caused by the gravitational pull of earth and sun. During high tide, the sea water expands. During low tide, sea water recedes back.

Rotation is the spinning of earth on it’s own axis. Earth takes 24 hours to complete one full rotation. It causes day and night on earth.

Revolution is moving of earth around the sun. Earth takes 365 days and 6 hours to complete one revolution. It causes change in seasons.

Isobars and Isotherms:

A line drawn on the map joining places of equal atmospheric pressure. An Isobar marked 1004 millibars represents high pressure while 976 millibars represents an area of low pressure.

A line drawn on the map or a chart showing places of equal temperature is known as Isotherms.

Atmosphere and Environment:

Atmosphere is the blanket of air surrounding the earth. It has layers of different gases which filters the harmful rays of the sun

Environment is things present in our surroundings. Moreover, it includes plants, animals, micro-organisms and even non-living things NCERT NOTES OF CLASS 7 GEOGRAPHY CHAPTER 1 ENVIRONMENT..

Star is also huge glowing balls of gases. Stars have their own heat and light. The closest star from the earth is the Sun.

Meteors, Meteoroids and Asteroids:

Meteors are usually a small object which enters earth’s atmosphere at very high speed. When it enters the earth’s atmosphere, it burns due to friction. Moreover, It appears like a broken star.

Meteoroids are pieces of iron or rock that orbit the sun, just as planets.

Many small objects made of rocks revolve around the Sun. They are usually found between Mars and Jupiter in our Solar System. The biggest asteroids can be hundreds of kilometers in diameter.

Satellite and Comet:

Satellite is an object that moves around the planet. However, It can be both, man-made and natural. Moon is a natural satellite of earth whereas, PSLV, INSAT, ARYABHATT are all man-made satellites.

Comets are snowballs of frozen gases, rock and dust that orbit the Sun. Example of a comet is Halley’s comet. It can be seen from the earth in every 75 years. Moreover, fortunate people have seen in 1986 and now will return back in 2061 What is solar system?.
