Question

What causes convection currents?

1. The Earth's rotation
2. The uneven heating of Earth's surface
3. The jet stream
4. The uneven cooling of Earth's surface

Answer 1

not sure if this answer helps,

Step-by-step explanation:

What is caused by the uneven heating of Earth and its atmosphere?

Global winds

This uneven heating produces global circulation patterns. For example, the abundance of energy reaching the equator produces hot humid air that rises high into the atmosphere. ... The air eventually stops rising and spreads north and south towards the Earth's poles.Solar heating of the Earth's surface is uneven because land heats faster than water, and this causes air to warm, expand and rise over land while it cools and sinks over the cooler water surfaces.
