Because water at the surface is always warmer than the water at depth. You get used to the temperature of the water surrounding you. When water surges up from the depth, you notice the change in temperature.
they come from the colder waters on the bottom of the oceans
Cold currents near coastlines often indicate the presence of upwelling. This is because upwelling brings cold, nutrient-rich waters from the ocean depths to the surface, leading to colder surface currents. Some examples of cold currents near coastlines that are associated with upwelling include the California Current, the Benguela Current, and the Canary Current.
Upwelling is the ocean process that brings vital nutrients from the bottom to the surface waters. It occurs when cold, nutrient-rich waters from the deep ocean rise to the surface, fueling the growth of phytoplankton and supporting a vibrant marine ecosystem.
Upwelling carries nutrients out of deep ocean waters, which are typically cold and rich in nutrients due to the decomposition of organic matter. This process occurs when deeper waters rise to the surface, often along coastlines or in areas where winds drive surface waters away. As these nutrient-laden waters reach the surface, they support high biological productivity, particularly in marine ecosystems.
Cold nutrient-rich waters move up to the ocean's surface through a process called upwelling, which occurs when winds push surface water away from the coast, allowing deeper water to rise and replace it. This upwelling brings nutrient-rich waters from the deep ocean to the surface, supporting the growth of phytoplankton and driving the marine food web.
True. Upwelling is a process where cold, nutrient-rich waters from the deep ocean rise to the surface, supporting the growth of phytoplankton and ultimately benefiting marine ecosystems.
no, they swim over warm and deep waters sometimes
The fishing industry is dependent upon the productive waters of an upwelling area. Upwelling brings nutrient-rich waters to the surface, supporting the growth of phytoplankton and leading to a rich ecosystem that sustains various marine species that are important for commercial fishing.
The movement of deep cold and nutrient-rich water to the surface is known as upwelling. This process occurs when winds blow across the ocean surface, pushing warmer surface waters away and allowing deeper waters to rise. Upwelling is vital for marine ecosystems as it brings nutrients to the surface, supporting the growth of phytoplankton and sustaining diverse marine life.
Upwelling can stop due to changes in wind patterns, such as a shift or weakening of the prevailing winds. Other factors include changes in ocean currents or the presence of surface water that is too warm to allow for cold, nutrient-rich waters to rise.
Upwelling is when the winds cause nutrient rich waters from lower levels of the ocean to replace the surface water. Upwelling's are usually caused by coastal surges or open oceans.
Upwelling occurs when deep, nutrient-rich waters rise to the surface, providing an influx of nutrients that support the growth of phytoplankton. Phytoplankton are the base of the marine food chain, attracting fish and other marine organisms to the area in search of food. This process makes upwelling regions some of the most productive marine ecosystems in the world.
