Direction In Which Ocean Floor Moves

Earth s rotation results in the coriolis effect which also influences ocean currents.

Direction in which ocean floor moves. Horizontal movements are referred to as currents while vertical changes are called upwellings or downwellings. The idea that the seafloor itself moves and also carries the continents with it as it spreads from a central rift axis was proposed by harold hammond hess from princeton university and robert dietz of the u s. The earth s lithosphere which includes the crust and upper mantle is made up of a series of pieces or tectonic plates that move slowly over time. Ocean currents are the continuous predictable directional movement of seawater driven by gravity wind coriolis effect and water density.

Indian ocean tsunami warning. Winds water density and tides all drive ocean currents. Earlier theories by alfred wegener and alexander du toit of continental drift postulated that continents in motion plowed through the fixed and immovable seafloor. East and south africa.

More people died in somalia 289 than in malaysia 75 numbers are estimated deaths. Unlike wind driven waves which only travel through the topmost layer of the ocean tsunamis move through the entire water column from the ocean floor to the ocean surface. These average rates of plate separations can range widely. A divergent boundary occurs when two tectonic plates move away from each other.

This force creates waves that radiate outward in all directions away from their source sometimes crossing entire ocean basins. Ocean water moves in two directions. Along these boundaries earthquakes are common and magma molten rock rises from the earth s mantle to the. 2004 indian ocean earthquake and tsunami 200 000 people died primarily in indonesia but also in sri lanka india and thailand mldr.

Aaway from the mid ocean ridge. Ocean water moves in two directions. Coastal and sea floor features influence their location direction and speed. Which statement best describes how patterns in ocean floor heat flow from a mid ocean ridge vary as one moves away from the ridge in any direction.

Direction in which the ocean floor moves. Heat flow decreases which statement correctly describes the distribution of earthquakes on planet earth. Similar to a person trying to walk in a straight line across a spinning merry go round winds and ocean waters get deflected from a straight line path as they travel. Horizontal movements are referred to as currents while vertical changes are called upwellings or downwellings.

The oceans hold one of the key pieces to the puzzle. Tsunami took between 15 mins 7 hours to reach coastlines many deaths due to lack of warning system.
