L/O: To understand what the effects of a Monsoon are for people and the environment “Calcutta gets between 160-170cm of rain every monsoon and now he have got so much rain in just three days,” G Debnath, chief of the local weather office said. http://www.youtube.com/watch?v=L8E-s5QTQOghttp://www.youtube.com/watch?v=L8E-s5QTQOg

2 The Indian Monsoon! L/O: To understand what the what effects of a Monsoon are for people and the environment “Calcutta gets between 160-170cm of rain every monsoon and now he have got so much rain in just three days,” G Debnath, chief of the local weather office said. I fully understand the LO I’m not really sure what the LO is about

3 What questions do you have for these boys ? Write at least 3 questions down in your books What do you think might be happening in this photo? Write an idea in your book

4 Use CIA World Factbook and write down 3 interesting facts about India’s: –People –Economy –Geography Starter!

6 Use the clues to help you label the regions in blue onto map 2. draw something to represent each feature, then use the text to annotate your map Himalayas High mountains reaching across northern India and bordering countries. The highest mountain in India is K2 in the Karakorum Range. India has the largest area of snow and glaciers in the world, covering 248,000km . Deccan Plateau An area of raised land occupying much of central India. It is bordered by two hill ranges: the Western and Eastern Ghats. Western Ghats Hills that are often called the ‘backbone of India’. They stretch from the tip of the country for 1000km along the western coast. Thar Desert Also known as ‘The Great Indian Desert’, it forms the border between India and south eastern Pakistan. Low-lying areas These are mainly near to the coast, which is 5,656km long. In the hot season (April to May), temperatures can reach over 40°C. River Ganges This holy river rises in the Himalayas and flows into the Bay of Bengal. Bay of Bengal A bay that borders India, Bangladesh, Myanmar, and northern Thailand. It has a triangular shape and has an area of 2,172,000km .

8 Finally…use Google Earth to locate and name the following… Where are all India’s people? Label your map with the 4 main cities; –New Delhi (the capital city) –Bangalore –Mumbai (Previously Bombay) –Kolkata (Previously Calcutta)

9 During the summer months Dry season and a wet season a time when there is a lot of rain, sometimes it causes flooding There are good things and bad things that can come from the monsoon What is a monsoon and how do they develop?

10 India’s monsoon lasts from June to October. Cherrapunji, situated high up in north east India, is one of the wettest places in the world with 11,000mm of rainfall! There are two distinct seasons dry and wet. The seasons change when the wind changes. When the land is warmer than the sea, air is constantly rising on land creating a low pressure. From April, heat builds over the land and rising of less dense air (as the land warms faster) form areas of low pressure, over North India and the Himalayas.

11 Over the oceans the air is cooler so to maintain the energy balance the air starts flowing from the oceans (high pressure) to the land (low pressure) bringing in the moisture rich southwest winds across southern Asia - the ‘wet’ phase which starts around June. When the monsoon rains have cooled the land so much that the air is warmer out to sea, the wind changes direction and become a north-easterly and the rains retreat and end around the end of October–the dry phase. What is a monsoon and how do they develop?

28 Are there any good things about the Monsoon? Mainly positive = Mainly negative = A bit of both =

29 Thumbometer How well do we understand the effects of monsoons for India?  or  or 

30 Where are we on our progress line? How much progress have you made? I fully understand the LO I’m not really sure what the LO is about

31 Create a mini story board to show how the Monsoon develops Think carefully about what you could draw to represent each stage Your task....

32 Finish off your story board Homework…
