Journal Entry 1 – Practical 1 Convection Currents
In this practical we learnt to investigate hot and cold convection currents. Being absent I had to catch up on the findings in the practical. I learnt that hot convection currents travel in a circle and change from hot to cold. I also learnt how cold currents travel in a straight direction
Q1. Explain what causes convection currents
Convection Currents are the result of the movement of heat moving from a hot region to a cold region. They are mainly caused through the unequal heat in both liquids and gases.
Q2. Use a diagram to clarify what a ‘hot’ current does.
Q3. Identify the direction of a ‘cold’ current.
The direction of a cold current is primarily straight as the warm air changes from hot to cold.
