Climate Changes?

In which area is the weather better?

1. Low-pressure area
2. High-pressure area
3. Minimum
4. depression

What is wind?

1. Air flowing from high to low pressure.
2. Air flowing from north to south.
3. Flowing of atmospheric particles
4. The high and low pressure areas clashing

What do you know about ocean currents?

- High- and low pressure areas 

- Wind 

- Air circulation 

- The Laws of Buys Ballot 

Low-pressure area 

- Minimum

- Effects of the rising air 

- Tropics 

What happens when air rises?

High-pressure areas 

- Maximum 

- Descending air 

- Deserts 

What happens when air descends?

Show me your sketch of the air circulation system

The Law of Buy Ballot 

First law: The wind flows from a high-pressure area to a low pressure area 

Second law: The wind in the northern hemisphere has a deviation to the right 

The wind in the southern hamisphere has a deviation to the left

Ocean currents 

It's not only that flows around the world. 

Ocean currents play a vitel role in distribution of tempertures on earth. 

But How? 

Ocean currents- Assignment 

Write a small paper about the effects and influence of the oceanic currents on the worldwide temperature. 

Explain: The cold and warm ocean currents -  How they distribute temperature - What sink regions are and how climate change is effecting the ocean currents.
