Downwelling is not associated with upwelling. Downwelling refers to the sinking of surface water in the ocean, whereas upwelling is the process where deep, nutrient-rich waters rise to the surface.
Upwelling is caused by currents on the surface. When water moves from the bottom of the ocean towards the surface it is called upwelling. Downwelling is when more dense water sinks. This process moves nutrients back to the deep part of the ocean.
They are both wind driven, if the Ekman Transport is moving in towrds the shore then downwelling will pull water from it and move it down and out. While when the Ekman Transport is moving out away from shore up welling will pull water up and feed the Transport. Note all directions are based on 90 degrees to the left or right fo the wind direction depending on wich Hemisphere.
All sorts of things can be compared and contrasted. For example a person can compare and contrast apples and oranges. A person can also compare and contrast the differences of a cat and a dog.
Downwelling is the process of accumulation and sinking of higher density material beneath lower density material. A common example is convection currents in fluids.
Downwelling is the process of accumulating higher density material beneath lower-density material, which can create currents along with the inverse process of upwelling. This is important for deep-sea creatures because it helps regulate the temperature of the oceans.

The movement of tectonic plates in the lower mantle is primarily driven by the process of mantle convection. This is caused by the heat released from the Earth's core, which creates circulation patterns in the mantle that can cause the plates to move. The upwelling and downwelling of material in the mantle contribute to the lateral movement of tectonic plates.
Downwelling currents in the oceans typically do not directly "gain" or "lose" energy. These currents are driven by processes such as density differences and wind patterns, rather than changing energy levels. However, factors like climate change can indirectly impact downwelling currents by altering ocean temperatures and salinity, which can influence their strength and distribution.
When my dad is mad, you can hear the upwelling in his voice.
