Which term describes the rising of cold water from deeper layers to replace warmer surface water Brainly?
Upwelling, if you are referring to large lakes or oceans.
Which term describes the rising of cold water from deeper layers?
Upwelling is the rising of cold water from deeper layers to replace warmer surface water.
What is upwelling and downwelling?
Downwelling is where surface water is forced downwards, where it may deliver oxygen to deeper water. Downwelling leads to reduced productivity, as it extends the depth of the nutrient-limited layer. Upwelling occurs where surface currents are diverging, or moving away from each other.
What causes upwelling?
Winds blowing across the ocean surface often push water away from an area. When this occurs, water rises up from beneath the surface to replace the diverging surface water. This process is known as upwelling.
Which term describes the rising of cold water from deeper layers to replace warmer surface water surface current upwelling downwelling density current?
Water then rises up from beneath the surface to replace the water that was pushed away. This process is known as “upwelling.”
What is surface water and groundwater?
Water that seeps deep into the ground is called groundwater. Surface water and groundwater are reservoirs that can feed into each other. While surface water can seep underground to become groundwater, groundwater can resurface on land to replenish surface water. Springs are formed in these locations.
What is upwelling in geography?
Encyclopedic entry. Upwelling is a process in which currents bring deep, cold water to the surface of the ocean. Upwelling is a result of winds and the rotation of the Earth.
What upwelling means?
Upwelling is a process in which deep, cold water rises toward the surface. This graphic shows how displaced surface waters are replaced by cold, nutrient-rich water that “wells up” from below.
What is the difference between coastal and equatorial upwelling?
Upwelling is driven by winds, and both the coastal upwelling along the eastern boundary currents and equatorial upwelling rely on the trade winds (See the satellite image depicting the productivity zones; note how they relate to coastal and equatorial upwelling zones.)

What is upwelling and why is it important?
Upwelling occurs when surface waters diverge (move apart), enabling upward movement of water. Upwelling brings water to the surface that is enriched with nutrients important for primary productivity (algal growth) that in turn supports richly productive marine ecosystems.
What is the surface of water called?
Surface water is a key component to the hydrologic cycle. Photograph by a_Taiga. Encyclopedic Entry Vocabulary. Surface water is any body of water above ground, including streams, rivers, lakes, wetlands, reservoirs, and creeks. The ocean, despite being saltwater, is also considered surface water.
What are the types of surface water?
Although surface water and groundwater can also feed into one and other. There are three types of surface water: Perennial – Perennial, or permanent, surface water persists throughout the year and is replenished with groundwater when there is little precipitation.
What is downwelling geography?
Downwelling is where surface water is forced downwards, where it may deliver oxygen to deeper water. Downwelling leads to reduced productivity, as it extends the depth of the nutrient-limited layer. Upwelling occurs where surface currents are diverging, or moving away from each other.
What is upwelling quizlet?
Upwelling. The upward motion of water. brings cold, nutrient rich water to surface.
What is the meaning of downwelling?
Downwelling is the process of accumulation and sinking of higher density material beneath lower density material, such as cold or saline water beneath warmer or fresher water or cold air beneath warm air. It is the sinking limb of a convection cell.
What is the definition thermocline?
A thermocline is the transition layer between warmer mixed water at the ocean's surface and cooler deep water below.
What is cold water upwelling?
Upwelling is a process in which deep, cold water rises toward the surface. This graphic shows how displaced surface waters are replaced by cold, nutrient-rich water that “wells up” from below. Conditions are optimal for upwelling along the coast when winds blow along the shore.
Is surface water weathering or erosion?
Surface water is a key agent of weathering and erosion. Weathering is a term that describes both physical and chemical changes in the minerals and rocks caused by differences in the environment in terms of pressure and temperature.
What is called as surface water?
Surface water is any body of water above ground, including streams, rivers, lakes, wetlands, reservoirs, and creeks. The ocean, despite being saltwater, is also considered surface water.
What is surface water of sea?
Surface water is any water that collects on the surface of the earth. This includes oceans, seas, lakes, rivers, or wetlands. Fresh surface water is maintained by rainfall or other precipitation, and it's lost through seepage through the ground, evaporation, or use by plants and animals.
What is upwelling and downwelling quizlet?
The upward motion of water. brings cold, nutrient rich water to surface. Typically only occurs in the top 200m. Downwelling. The downwards movement of water.
What causes upwelling quizlet?
Upwelling is caused by wind that blows parallel to the coastline. The wind causes the water to move perpendicular to it, away from the coast. When the water near the coastline moves away, deeper ocean water must replace it. The water moves vertically up towards the surface.
What is the thermocline layer?
A thermocline is the transition layer between warmer mixed water at the ocean's surface and cooler deep water below.
What is the difference between El Niño and La Nino?
El Niño events are associated with a warming of the central and eastern tropical Pacific, while La Niña events are the reverse, with a sustained cooling of these same areas. These changes in the Pacific Ocean and its overlying atmosphere occur in a cycle known as the El Niño–Southern Oscillation (ENSO).
What is erosion and deposition?
Erosion is when materials, like soil or rocks, are moved by wind or water. All these materials are called sediments. Deposition is when those sediments are deposited, or dropped off, in a different location. These processes change the way the surface of the earth looks over time.
What is deposition in geography?
Deposition is the laying down of sediment carried by wind, flowing water, the sea or ice. Sediment can be transported as pebbles, sand and mud, or as salts dissolved in water. Salts may later be deposited by organic activity (e.g. as sea shells) or by evaporation.
What is surface water groundwater?
Surface water includes any freshwater that's sent into wetlands, stream systems, and lakes. On the other hand, groundwater exists in subterranean aquifers that are situated underground. Most groundwater is obtained from snowmelt and rainfall that gets into the bedrock via the surrounding soil.
What is sea water called?
Salt water (or saline water) is water with an amount of salt in it. It usually means the water from the seas and oceans (sea water). Almost all the water on Earth is saline. River water, however, is usually not saline.
What is an upwelling quizlet?
Upwelling. The upward motion of water. brings cold, nutrient rich water to surface.
