- 4. Factors influencing the climate of a place The climate of any place on Earth is influenced by the distance of a place from the sea, direction of winds, altitude of a place, temperature ,amount of rainfall and latitude or distance of a place from the equator. Latest study these factors in detail
- 6. Distance of a place from the sea Places near the sea have a moderate type of climate as compared to those located in the interior even if they lie on the same latitude. This is because water heat and cools comparatively slower then the land. When warm air over the land rises, it is replaced by cool air from the sea. The sea breeze cools the coastal areas in summer and warms them in winter. On the other hand, places away from the sea have an extreme type of climate. average in amount
- 7. Direction of winds: Winds blowing from cool regions make a place cool. Similarly ,winds coming from hot regions ,such as a desert ,make a place hot. Winds blowing from the Sea cause humidity and make a place humid. a relatively high level of water vapour in the atmosphere.
- 8. Altitude of a place: Places which are located at higher altitude are cooler than the places located at lower altitudes. It is because the higher you go, the cooler it becomes. the height in relation to sea level or ground level
- 9. Distance of a place from the equator: The rays of the sun fall almost directly on the Equator. Therefore , places on the equator or near to it are hotter than the places that are at higher altitudes. The rays of the sun become more slanted as we move from the equator towards the poles. In other words, the amount of the sunlight received differs on different latitudes. It becomes less and less as we move towards the poles. The slanted rays of the sun travel a long distance through the atmosphere. The heat is separate over a large area, thus making the places away from the equator less hot.
- 11. Temperature and rainfall: The temperature of a place and the amount of rainfall it receives also determine the climate of a place.
- 13. The Temperature zones based on the intensity of Sunlight the earth receive it has been divided into three major temperature or known as heat zones 1. The Torrid zone 2. The Temperature zone 3. The Frigid zone
- 14. The Torrid zone The Torrid zone extends from the Tropic of Cancer that is 23 ½° North to the Tropic of Capricorn 23½°S. The equator passes right through the centre of this zone. The zone between the Equator and the Tropic of Cancer is called the North Torrid zone. The zone between the equator and the Tropic of Capricorn is called the South Torrid zone.
- 15. This zone receives strong sunlight throughout the year it is is the hottest zone of the earth. This zone receives a lot of rainfall. The climate of this zone is hot wet and humid. This type of climate is known as the tropical climate. The regions located near the equator do not experience different seasons. However, as we move away from the equator, the seasons become more distinct.
- 16. The torrid zone refers to the area of the earth between the Tropic of Cancer and the Tropic of Capricorn The temperature in these tropical zones is warm and humid and generally moist year-round. However, the torrid zone encompasses a variety of topographic features that affect climate. Consider that many deserts and mountains fall within the latitudes defining the torrid zone.
- 18. The Temperature zone In the Northern hemisphere, the Temperature zone lies between the Tropic of Cancer(23½°N) and the Arctic circle (66½°N). The zone is known as the North Temperate zone. In the Southern hemisphere ,It lies between the Tropic of Capricorn (23½°S)and the Antarctic circle(66½°S). Thus ,zone is known as the South Temperate zone. This zone lies between the Torrid Zone which is extremely hot and the Frigid zone which is extremely cold.
- 19. The meaning of the temperate is 'mild'. It means that the climate here is neither very hot nor very cold as this zone receives the slightly slanting rays of the Sun. Both the summer and the winter seasons are distinct in this zone. The days are longer during summer and shorter during winter. The area or region between the Tropic of Cancer and the Arctic circle or between the Tropic of Capricorn and the Antarctic circle
- 20. Frigid zone In the Northern hemisphere, the Frigid zone extends from the Arctic Circle (66½°N) to the North pole (90°N) .This is called the North Frigid zone. In the Southern hemisphere, it is extended from the Antarctic Circle(66½°S) to the South pole(90°S), and is called the South Frigid zone. As the regions under the frigid zone receive extremely slanted rays of the Sun, the intensity of the heat is very less. Therefore, these regions are extremely cold. Many of the places lying in the this zone are covered with snow and ice throughout the year.
