upwelling การใช้

• Then Pangea broke apart, perhaps because of upwelling convection currents.
• Cooler water then rises from below, a process called upwelling.
• Currently, areas of oceanic upwelling cause the formation of phosphates.
• Winds blow in directions that don't cause upwelling.
• Areas of upwelling provide supplies of nitrogen from below the euphotic zone.
• Nitrate is depleted in near-surface water except in upwelling regions.
• Changes in bathymetry can affect the strength of an upwelling.
• They are highly abundant along the upwelling regions of the current systems.
• This prevents nutrient-rich upwelling which has reduced productivity.
• Some equatorial regions of upwelling, where nutrients are abundant and spicules.
• The space left behind by departing lithosphere is filled by upwelling asthenosphere.
• This slow anomaly is considered to be a plume upwelling.
• Large-scale upwelling is found in the Southern Ocean.
• By alongshore winds, upwelling current flows to the coast.
• The coastal upwelling in the south-eastern Arabian Sea occurs seasonally.
• When El Nino starts, the upwelling diminishes and the surface waters warm.
• Coastal zones provide nitrogen from runoff and upwelling occurs readily along the coast.
• Natural causes include coastal upwelling and changes in wind and water circulation patterns.
• The intrusions were formed when upwelling asthenosphere partially melted thick overlying oceanic crust.
• It was suggested that the cause was mantle upwelling.
