What provides the thermal energy for currents to be formed?
Thermal energy from the sun is the primary driver for the formation of ocean currents. The sun's heat causes water to expand and rise at the equator, creating warm surface currents. As the water moves towards the poles and cools, it becomes denser and sinks, completing the cycle of ocean circulation.
Because of the Coriolis effect surface currents in the Southern Hemisphere are deflected?
The Coriolis effect causes surface currents in the Southern Hemisphere to be deflected to the left. This deflection occurs due to the rotation of the Earth, with the Coriolis force being stronger closer to the poles. As a result, ocean currents in the Southern Hemisphere tend to move in a clockwise direction.
Are convection currents important to continental drift?
Convection causes hot magma to rise towards the surface where it turns and flows parallel to the surface as it hits the crust. As the liquid rock flows beneath the crust it drags the crustal plate along and causes the continents that are on those plates to drift.
What happen as thermal energy is transferred from the core to the mantle?
As thermal energy is transferred from the core to the mantle, it causes convection currents in the mantle. These currents are responsible for the movement of tectonic plates at the Earth's surface. This movement leads to processes such as seafloor spreading, subduction, and volcanic activity.
What causes a surface wave?
Surface waves are caused by the interaction between seismic waves and the Earth's surface. These waves travel along the Earth's crust and can cause the ground to shake horizontally and vertically. Surface waves are typically the most destructive type of seismic waves during an earthquake.
What type of current is caused by wind on the oceans surface?
Surface ocean currents are caused by winds. As wind blows across the surface, the wind pulls the water and causes waves.
What causes surface currents to move?
Randomism .
What is primary causes of crustal movement?
Convection currents in the mantle.
What is the primary force that causes the sea-floor to spread?
Convection currents
An increase in wind causes this current to increase What type of current is it?
Convection is the process that causes warm air to rise and cold air to sink. As such, the winds caused by this process are called convection currents.
What causes surface and deep currents?
The gravitation pull on the earth.
What factor causes surface currents north and south of the equator to move in different locations?
Surface currents are created by air currents, earth's rotation, and positions of the continents.
How the sun is the major source of energy that powers surface currents?
The sun is major source of energy that power surface currents because the sun causes wind to blow and winds cause surface currents to form
What is the primary source of energy for ocean currents and waves?
Ocean currents at the SURFACE -- their primary cause is SOLAR ENERGY. Due to solar energy, much of the wind pattern originates and this wind pattern in turn causes ocean currents on the surface.
What causes ocean surface currents?
A surface current is a current caused by wind direction
What causes deep ocean surface currents?
The gravitation pull on the earth.
What force between the ocean and wind causes surface currents?
