What characteristic of a current is important in affecting climate?
the air in the atmosphere and the waters in our oceans circulate in known patterns in an effort to redistribute the energy. In the atmosphere, we end up with the prevailing wind bands in both hemispheres. In the oceans, we end up with both surface and deep water currents. It is the surface currents that have a marked effect on climate.
Are wind-driven currents near the surface or in the deep waters?
Vertically
What oceans do the great white live in?
Coastal Surface waters in all major oceans.
Currents that involve warm water flowing in different directions at different speeds close to the top of oceans?
Surface currents involve warm water that flows in different directions and different speeds that stay close to the top of the oceans. They originate in tropical waters and flow in circular motions from all the major gyres of the world ocean.
How do differences in density cause currents to flow both in the surface waters of the oceans and in the bottom waters of the ocean?
The differing densities of water create a consistent movement between the various thermal layers. As water is cooled, it actually expands, so it rises, and as it is warmed it sinks.
What causes cold nutrientrich waters to move up to the oceans surface?
ocean fronts
What create ocean currents?
Sunlight warms the waters on the ocean surface. Some heat energy is transferred to cooler waters through convection.
What makes up the surface waters in the hydrosphere?
Surface waters in the hydrosphere are made up of oceans, seas, lakes, rivers, and streams. These bodies of water are interconnected through the water cycle, with water evaporating from oceans and lakes, forming clouds, and eventually falling back to the surface as precipitation.
What kind of climate does a Portuguese man of war live in?
The Portuguese man-of-war prefers the warm waters of the Pacific, Indian, and Atlantic oceans, but are found in all oceans. They live on the ocean surface. The Portuguese man-of-war cannot propel itself, but is moved along by currents, tides, and waves.
What causes water currents?
Surface ocean currents are mainly wind-driven and occur in all of the world's oceans. Examples of large surface currents that move across vast expanses of ocean are the Gulf Stream, the North Atlantic Current, the California Current, the Atlantic South Equatorial Current, and the Westwind Drift. Associated with surface currents are counter-surface and underlying currents. Surface ocean currents are deflected to the right in the Northern Hemisphere and to the left in the Southern Hemisphere due to the Coriolis effect. The Coriolis effect holds that because the Earth is spinning, surface waters move in a clockwise direction in the Northern Hemisphere and in a counterclockwise direction in the Southern Hemisphere. The currents eventually come into contact with the continents which deflect them, creating giant oceanic current circles known as gyres. Vertical and ocean-bottom currents are mainly driven by density differences caused by changes in temperature and salinity. Originating in polar regions, cold, salty waters sink to the ocean bottom and move toward the opposite poles where they again surface. Vertical upwelling currents can also be caused by winds "blowing off" a coastline. The displaced waters are then replaced by underlying bottom waters. Currents are important to marine life as they help to move food and nutrients, making them available for photosynthesis, metabolic requirements and/or consumption.
What are the surface waters of the earth called?
Surface waters of the Earth are typically referred to as "water bodies" or "water sources," which include oceans, seas, rivers, lakes, and streams. These surface waters play a crucial role in supporting various ecosystems and human activities.
The winds that are most involved in forming ocean currents are the?
The winds most involved in forming ocean currents are the global wind patterns, such as the trade winds, westerlies, and polar easterlies. These winds drive the surface waters of the oceans, creating ocean currents that can transport heat, nutrients, and marine life around the globe.
