How does downwelling drive thermohaline circulation?
Downwelling is a crucial process in thermohaline circulation, as it occurs when dense, cold, and salty water sinks into the ocean depths, particularly in polar regions. This sinking water drives the global conveyor belt of ocean currents, facilitating the transport of heat and nutrients across the world's oceans. As downwelling occurs, it helps regulate climate by redistributing warm and cold water, influencing weather patterns and marine ecosystems. Ultimately, downwelling is a key mechanism that maintains the balance of oceanic circulation and global climate systems.
How is wind driven ekman transport related to coastal upwelling and downwelling?
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.
What is responsible for movement of tectonic plates in lower mantle?
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.
Do density currents ocour in the pacific ocean?
Yes, density currents occur in the Pacific Ocean, as they do in other oceanic regions. These currents are driven by differences in water density, which can result from variations in temperature and salinity. In the Pacific, processes such as upwelling and downwelling contribute to the formation of density currents, impacting nutrient distribution and marine ecosystems. Such currents play a crucial role in the ocean's thermohaline circulation.
How does a continent affect the movement of a surface current?
A continent can disrupt the flow of a surface current by acting as a barrier and forcing the current to change direction or split. This can create eddies, upwelling, or downwelling of water that can impact the speed and direction of the current. Continents can also influence the formation and intensification of currents by shaping the overall circulation patterns in the ocean.
What downwelling defined as?
Downwelling is the process of accumulation and sinking of higher density material beneath lower density material. A common example is convection currents in fluids.

Which is not associated with up-welling?
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.
Is downwelling of the oceans currents gianing or losing energy?
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.

What are the benefits of downwelling?
Downwelling is a crucial process in ocean circulation where surface waters sink, facilitating the transport of oxygen and nutrients to deeper layers. This process supports marine life by distributing essential nutrients, promoting biological productivity in the ocean. Additionally, downwelling helps regulate global climate by influencing heat distribution and carbon sequestration in the deep ocean. Overall, it plays a vital role in maintaining healthy marine ecosystems and stabilizing climate patterns.
How and why would downwelling affect fisheries in coastal areas on the eastern sides of ocean basins?
Downwelling in coastal areas on the eastern sides of ocean basins can lead to reduced nutrient supply from deeper waters to the surface, affecting primary production and thus the food chain for fisheries. This can result in lower fish populations and decreased productivity in those areas. Additionally, downwelling can cause changes in water temperature and oxygen levels, further impacting fish habitat and migration patterns.
Upwelling and downwelling?
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.

What are the currents that flow vertically called?
The currents that flow vertically in the ocean are called "upwelling" and "downwelling" currents. Upwelling occurs when deep, cold, nutrient-rich water rises to the surface, often supporting marine life. Downwelling, on the other hand, happens when surface water sinks due to density differences, often transporting oxygen-rich water to deeper layers. Both processes are crucial for ocean circulation and marine ecosystems.
What is responsible for movement of tectonic plates in lower mantle?
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.
