Task 2
· Why is Lee tired after cycling to the Sea in the morning? Because of the convection where the heat from the land rises up and the cold air from the sea move to the land , take place instead of the hot air.· Predict what will happen when Lee cycles home in the evening. He will be tiring since the wind is blowing in his way. This is because the land cools down and he sea is still hot so the convection works the opposite way from morning.
