India - an emerging country

Read page 51 together

Explain in your own words Salim's expression that 'India is the centre of the world'.

This chapter:

1. India, land of monsoons
2. India, land of contrasts
3. Boomin India
4. India shining?
5. Emerging countries

Section 1 - India, land of monsoons

• Relief
• Monsoon rains
• Flooding 

Do now:

Read section 1.

Make section 1, exercise 1, 2, 3, 4, 5, 6

India - land of monsoons

Lesson goals:

After this lesson you:

• are able to give the definition of a monsoon
• can explain Buijs Ballot's Law
• can explain the Coriolis effect

India - land of monsoons

Monsoon: a wind that reverses its direction every six months

• Dry season
• Rainy season

Winter

Wind

What is wind?

• Moving air

• Movement because of difference in air pressure

Air pressure

Note:

Air pressure is the amount of air pushing down on the earth. This pressure can be high or low.

• Low pressure: in areas where the air is ascending
  
• High pressure: in areas where the air is descending
  

Air pressure

In which direction do winds move?

1. From a low to a high pressure area
2. from a high to a low pressure area
3. Always from sea to land
4. Totally random

High or Low?

• Decide for each area if it is a high pressure or a low pressure area. 
  
• Think of a reason why the winds don't move in a straight line.
  

Winds move

1. towards the equator
2. away from the equator

Winds move

1. towards the poles
2. away from the poles

Winds move in a straight line

1. True
2. False

The wind System

Note:

• Buijs Ballot's Law is says that wind travels from a maximum (high pressure area) to a minimum (low pressure area).
  
• The wind doesn't move in a straight line because of the earth's rotation.
  
• The wind in the Northerns hemisphere turns to the right, wind in the southern hemisphere turns to the left (standing with your back to the wind!)

Monsoon

Note:

A monsoon is a wind that reverses its direction every six months.

The winds change around the geographical equator because the tropical minimum moves along with the earth's axis.

See GG nr. 47 & figure 3.22
