Convection currents, which affect weather and climate, are created

by

The uneven heating of the earth.

Explanation:

Convention current is the entire chunk of liquids or gas that move from one place to the other. It is not just the transfer of heat and energy but the mass movement of fluids as well. This transfer drives the oceans’ current and the atmospheric weather. Since heated fluids like the ocean’s water bodies are less dense, according to science, they will rise up above and pull the cooler air into its place. There are various conventions, which include oceans, air, and water conventions. They all follow the same principles and as a result affect weather and climate.

they all focused on themes about the inevitability of death.
