The temperature of the air.
Temperature is the property of air that has the most influence on convection currents. Warm air is less dense than cold air, causing it to rise and create upward convection currents. Conversely, cold air is denser and sinks, leading to downward convection currents.
The mechanical layer of Earth with the most active convection currents is the asthenosphere. Located just below the lithosphere, the asthenosphere is composed of semi-fluid rock that can flow slowly over geological time. This flow drives the movement of tectonic plates above it, leading to phenomena such as earthquakes and volcanic activity. The convection currents in the asthenosphere are crucial for the dynamics of plate tectonics.
In a convection current the kinetic energy will most likely be a small part of the total as the rate of flow won't be very high. Most heat transfer in convection will be simply thermal energy transfer, ie from a warmer place to a cooler one.
Convection currents, driven by the uneven heating of the Earth's surface, significantly influence a region's climate and weather patterns. As warm air rises and cool air sinks, these currents can create localized wind patterns, precipitation, and temperature variations. This process is particularly important in shaping ocean currents, which further impact coastal climates and ecosystems. Consequently, regions can experience distinct weather phenomena, such as storms or dry spells, based on the behavior of convection currents.
Geologists have hypothesized that the movement of tectonic plates is related to convection currents in the earth's mantle. Convection currents describe the rising, spread, and sinking of gas, liquid, or molten material caused by the application of heat.

The mantle is the mechanical layer of Earth that has the most active convection currents. These currents are responsible for the movement of tectonic plates and drive various geological processes on the Earth's surface.

Most convection currents that cause seafloor spreading are thought to be located in the asthenosphere, which is a semi-fluid layer of the Earth's upper mantle beneath the lithosphere. The movement of these convection currents is believed to drive the motion of tectonic plates.

'Convection' currents do several things, most notably by creating wind. These currents also move clouds, providing rain, as well as other atmospheric features.

the layer that has convection currents is the mantle
The mechanical layer of Earth that has the most active convection currents is the asthenosphere, which is part of the upper mantle. This semi-fluid layer allows for the movement of tectonic plates above it, driving geological processes such as continental drift and volcanic activity. The convection currents in the asthenosphere are generated by the heat from the Earth's core, influencing the dynamics of the Earth's lithosphere.
