What layer of the atmosphere do convection currents occur?

Generally convection is limited to the troposphere, which is the lowest layer of Earth's atmosphere and contains 80% of the atmosphere by mass. Gravitational systems order by density with the lowest layers being the most dense. read more

The aesthenosphere is a layer of solid rock that is so hot, the rock melts and flows like a liquid, easily breaking apart. The most dramatic earthquakes are caused by rocks in the aesthenosphere breaking apart. Large convection currents transfer heat to the surface of the Earth, and these currents cause the magma to break apart. read more

Convection Naturally, convection also occurs in the oceans, where warm water rises and cold water sinks--a driving force for ocean currents; and it also occurs in the atmosphere, where it is the main driving force for weather. read more
