Weather and climate.pptx 2
- 2. Difference between Climate and Weather:
- 3. Factors that affect climate: The main reason for different climates in different places is temperature- varying amount of heat received in different parts of the Earth. The variations in temperature in different places mainly depends on: Distance from the Equator Distance from the sea Rainfall Wind Direction Altitude
- 4. Distance from the Equator: Places closer to the Equator are hotter and more humid than other places on the Earth, and also receive more rainfall. The polar regions are extremely cold with hardly any sunshine.
- 5. Distance from the Sea: Coastal areas are generally cooler than land-bound areas, because the temperature of the oceans remains the same throughout the year. In summer, places like Karachi are hot during the day, but generally pleasant in the evenings because of the sea breeze. On the other hand, Lahore, which is bound by land on all sides, remains hot all through the day and night during the summer.
- 6. Rainfall: The temperature of a place changes significatly after rainfall. Just before the rain, it becomes hot, humid and still, and becomes pleasant after the rainfall. Places on or near the Equator experience this throughout the year.
- 7. Wind Direction: Wind blows from a colder place, it will have a cooling effect on the place it reaches. On the other hand, if it blows from a hotter region, temperatures will rise in the area it blows towards.
- 8. Altitude: Places located above sea level are cooler than places on or near sea level. In Pakistan, people often travel to Murree, Swat, and other hill stations to escape the scorching summer heat, because these places are located in the high mountains where the temperature is lower.
