Turbidity currents are sediment-laden flows that occur along the ocean floor, typically triggered by underwater landslides or disturbances, and travel rapidly down the continental slope. In contrast, deep currents, also known as thermohaline currents, are driven by differences in water temperature and salinity, resulting in a slow, global circulation pattern in the ocean. While turbidity currents are often short-lived and localized, deep currents are persistent and play a crucial role in regulating the Earth's climate and oceanic nutrient distribution.

What is the difference between surface currents and deep currents?
Deep ocean currents are in the depths of the oceans. Surface current are at the surface, not deep down. Deep ocean currents bring vitamins and nutrients to the shore, surface currents do not. Deep ocean currents are caused by salinity and temperature differences. Surface currents are cause by the force and impact of the wind.

Are deep currents caused by differences in pressurre?
All currents are caused by differences in pressure.
How Do Deep Currents Form?
Differences in temperature and in density of seawater drive deep ocean currents.
Which feature of the sea floor is cut by turbidity currents?
Submarine canyons are a common feature of the sea floor that can be cut by turbidity currents. These currents are fast-moving underwater sediment flows that can transport large amounts of sediment and carve deep channels into the ocean floor. With their high energy and ability to transport sediment, turbidity currents are capable of reshaping submarine canyons over time.
Explain how turbidity currents are related to submarine canyons?
Created by a series of complex processes, submarine canyons continue to be carved by sporadic turbidity currents waterfalls of sand, gravel, and muddy sediments.
How is an ocean submarine canyon formed?
An ocean submarine canyon is typically formed through a combination of processes such as erosion by currents, turbidity flows, and underwater landslides. These can carve deep, V-shaped valleys in the seafloor, similar to canyons on land. Over time, the canyon can deepen and widen as sediment is transported and deposited within it.
What currents caused by temperature and density differences?
deep
A large underwater area between continents?
A large underwater area between continents is called a submarine canyon. These are deep, steep-sided valleys cut into the seafloor by turbidity currents, often connecting continental shelves to the deep ocean. They can be thousands of meters deep and hundreds of kilometers long.
In which zone would you expect to find turbidity currents?
Turbidity currents are typically found in the abyssal zone of the ocean. These underwater avalanches of sediment flow down the continental slope and into the deep ocean basin, where they can transport large amounts of sediment over long distances.
Deep currents are the result of?
Deep currents are the result of differences in water density caused by variations in temperature and salinity. These differences create a gradient in density which drives the movement of water at depth in the ocean. The movement of deep currents plays a crucial role in transporting heat, nutrients, and oxygen around the world's oceans.
What currents are currents caused by temperature differences the water?
Thermohaline currents, also known as ocean circulation currents, are caused by temperature and salinity differences in the water. These currents play a crucial role in distributing heat around the globe and influence climate patterns.
