How Do Convection Currents Move Tectonic Plates? How is the Earth's crust related to tectonic movement? The convection currents in tectonic plates occur in the geosphere. The radioactive decay of elements is responsible for the heat deep within the earth, and this results in the creation of magma. Magma is a type of material that can be semi-fluid or completely fluid.

What Causes Plate Tectonics? Plate tectonics is primarily caused by Earth's cooling mechanism, which generates convection currents in the planet's mantle that trigger slow but constant tectonic plate movement. This phenomena occurs on the boundaries of adjacent plates, which are classified as divergent, convergent and transform boundaries.

Ocean current An ocean current is a continuous, directed movement of seawater generated by forces acting upon this mean flow, such as breaking waves, wind, the Coriolis effect, cabbeling, temperature and salinity differences, while tides are caused by the gravitational pull of the Sun and Moon.

Chapter 5 Plate Tectonics Section 5 Plate Tectonics The Earth's crust is divided into huge plates that move and interact with each other due to convection currents in the mantle. The theory of plate tectonics explains the formation, movement, and subduction of Earth's plates.

- Currents may also be generated by density differences in water masses caused by temperature and salinity variations. These currents move water masses through the deep ocean—taking nutrients, oxygen, and heat with them. Occasional events also trigger serious currents. Huge storms move water masses.

Plate tectonics Plate tectonics is a theory of geology. It has been developed to explain large scale motions of the Earth's lithosphere. This theory builds on older ideas of continental drift and seafloor spreading. Dissipation of heat from the mantle is the original source of energy driving plate tectonics. Exactly how this works is still a matter of debate.

- What drives the process of plate tectonics. Tectonic plates are pieces of the Earth's crust and uppermost mantle, together referred to as the lithosphere. The plates are around 100 km thick and consist of two principal types of material: oceanic crust and continental crust. The composition of the two types of crust differs markedly, with basaltic rocks dominating oceanic crust, while continental crust consists principally of lower density granitic rocks.

- Quick Answer. The three primary causes for tectonic plate movement are the convection of material in the mantle, gravity and the rotation of the planet. These forces cause each of the seven major plates and numerous other microplates to move independently of the others at a rate of a few centimeters per year.

Causes of Tectonic Plate Movement As this happens, the plates smash into each other, slide past each other or are pushed under another plate. This movement of the plate along with the upwelling of the mantle by the convection currents may also cause secondary actions that assist in plate movement.lab Pull. Another mechanism that forms as a result of plate movement is slab pull. As the plate is pushed along, it may run into another plate. Oceanic crust is easily forced under another plate and back into the mantle.

Plate Tectonics There are three main driving forces for the movement of the Earth's tectonic plates. They are mantle convection, gravity, and the Earth's rotation. Mantle convection is the most widely studied method of tectonic plate movement and it is very similar to the theory developed by Holmes in 1929.n 1961 and 1962, scientists proposed the process of sea floor spreading caused by mantle convection to explain the movement of the Earth's continents and plate tectonics.

What are tectonic plates and how do they move? The Earth's plates are riding on top of the currents caused by these processes. The main features of plate tectonics are: 1  The Earth's surface is covered by a series of crustal plates. 2  The plates are composed of crustal rock and solid upper mantle which is called the lithosphere.* 3  Plates are composed of continental and oceanic crust. The plates are composed of crustal rock and solid upper mantle which is called the lithosphere. * 2  Plates are composed of continental and oceanic crust. 3  The oceanic crusts are continually moving, spreading from the center, sinking at the edges, in a process of recycling.

Chemicals That Kill Grass Grass that grows in undesirable locations, such as between the cracks of a sidewalk, can be killed with chemicals called non-selective herbicides. Every herbicide, even ones with the same active ingredient, can have different strengths. Therefore, purchase herbicides in a ready-to-use container for easy use.

Ocean currents can be generated by wind, density differences in water masses caused by temperature and salinity variations, gravity, and events such as earthquakes. 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 them. For More Information:

- Surface ocean currents are also driven by an effect caused by Earth's rotation on its axis known as the Coriolis effect. The rotation of Earth acts to turn or deflect prevailing winds clockwise in the Northern Hemisphere and counterclockwise in the Southern Hemisphere, which deflects the surface currents.
