Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
If we boil water in a pot on an electric burner. How is our simulation of demonstrating convection currents different than the currents in the atmosphere and ocean?
A
the warm air in our model sinks instead of rises
B
the heat source for Earth is the sun which heats from above
C
the currents are all flowing in the same direction
D
warm water is less dense than warm air causing a difference between the models
Explanation: 

Detailed explanation-1: -Strong winds cause evaporation, so the ocean surface cools, weakening the stratification. As a result, the surface waters are overturned and sink while the “warmer” waters rise to the surface, starting the process of convection.

Detailed explanation-2: -The heat from the stove burner will heat the metal pot through convection, causing conduction to heat the water.

Detailed explanation-3: -Convection currents occurring in the ocean– The Oceanic currents are also the convection currents. These are caused due to the difference in the water density and the temperature occurring in different parts of the ocean.

Detailed explanation-4: -How does convection affect the weather? Convection within the atmosphere can often be observed in our weather. For example, as the sun heats the Earth’s surface, the air above it heats up and rises. If conditions allow, this air can continue to rise, cooling as it does so, forming Cumulus clouds.
