Currents On Ocean Floor
An ocean current is a continuous directed movement of sea water generated by a number of forces acting upon the water including wind the coriolis effect breaking waves cabbeling and temperature and salinity differences.
Currents on ocean floor. Depth contours shoreline configurations and interactions with other currents influence a current s direction and strength. Library research before you begin exploring read a book or two about oceans. How to construct some ocean currents. Ocean currents are located at the ocean surface and in deep water below 300 meters 984 feet.
Ocean currents abiotic features of the environment are continuous and directed movements of ocean water. Ocean currents are primarily horizontal water movements. Support artifexian on patreon. They can move water horizontally and vertically and occur on both local and global scales.
The shifting plates may collide converge move away diverge or slide past transform each other. Ocean currents ocean floor ocean in a bottle craft and ocean lapbook step 1. Here are some suggestions but if. Coastal and sea floor features influence their location direction and speed.
They examine deep currents the ocean atmosphere relationship that influences weather and climate the transmission of light and sound through water and the ocean s interactions with its boundaries at the seafloor and the coast. Winds water density and tides all drive ocean currents. Ocean explorations layers of learning units come with many explorations that you choose between. Learn about ocean currents coastal erosion sea level rising and other topics in physical oceanography.
On the ocean floor water masses forced through narrow openings in a ridge system or flowing around a seamount may create currents that are far greater than in the surrounding water affecting the distribution and abundance of organisms as well as the scientists and their equipment seeking to study these organisms. A stream like movement of the ocean water far below the ocean surface surface currents a horizontal movement of ocean water that is caused by winds and that occurs at or near the ocean surface. These currents are on the ocean s surface and in its depths flowing both locally and globally. An ocean current flows for great distances and together they create the global conveyor belt.
Convection currents in the molten mantle cause the plates to slowly move about the earth a few centimeters each year.
