Where in the earth do convection currents occur? Convection currents happen in the mantle and cause tectonic plates  to drift.   The earth is made up of the iron and nickel core, then the mantle  then the crust. And th…e earths surface is made up of tectonic  plates. These plates move due to convection currents. 3 people found this useful.

Density Creates Currents As the air cools, it becomes more dense, sinks to the floor, and eventually completes a circuit of the room. A circular convection current is set up. Circular currents like this are called convection cells. Convection currents like this also take place in the atmosphere (see the picture below). A convection cell can also occur in the atmosphere.

Earth's Interior/Plate Tectonics Convection currents in the astheosphere cause the plates to move constantly but slowly. The hotter, less dense rock rises. While rising it cools making it more dense. Once it is cool and becomes more dense, it starts to sink.

- The question does not state what a convection current is, therefore I will define it for readers. A convection current occurs when there is a difference in heating at two altitudes. The sun provides and generates heat for the earth, which is transformed from solar radiation to heat on contact with the earth.

What causes convection currents in the earths mantle? Convection currents are caused by the heat from the inner core. A layer in the mantle, called the asthenosphere, is fluid-like and is heated by the core, thus inducing convect … ion currents to form. 26 people found this useful.

How convection currents form? Making the world better, one answer at a time. Convection currents form in the earth's asthenosphere (the middle mantle) due to heat from the core. They can also form in any other fluid (scientifically, a fluid can be either a liquid or gas), such as boiling water, hot soup, and even the air. But let's use the asthenosphere as an example because it's a good one.

Currents in the Earth's System Focus Question: What is the source of energy for convection currents in the geosphere? Convection currents in the magma drive plate tectonics. Heat generated from the radioactive decay of elements deep in the interior of the Earth creates magma (molten rock) in the aesthenosphere. The aesthenosphere (70 ~ 250 km) is part of the mantle, the middle sphere of the Earth that extends to 2900 km.

How Ocean Currents Work These circular wind patterns create spiral ocean currents called gyres. Five major gyres flow both north and south of the equator: the North Atlantic, South Atlantic, North Pacific, South Pacific and Indian Ocean gyres. Smaller gyres also exist at the poles, and one circulates around Antarctica. Short-lasting, smaller currents often spin off both small and large gyres.

What causes convection currents in the earths mantle? Convection currents begin due to the extreme heat of the inner  core. The … inner core heats up the very bottom of the mantle. The  heated up substances within the mantle has a higher temperature  than those higher in the mantle and closer to the surface of the  earth.

Hot Springs on the Ocean Floor Hydrothermal vents also are found in areas of the ocean floor that are spreading, such as at mid-ocean ridges, where tectonic plates are being pulled apart. This movement allows the molten magma to rise from deep inside the Earth, superheating the cold ocean water around it.

What Causes Convection Currents? Quick Answer. Convection currents are caused by an uneven temperature within something. Convection currents happen within the Earth's magma, water and air. It can happen in anything that is not solid and has parts that are cooler or warmer than other parts. When something is cool, it sinks, and when it is hot, it rises.

- Heat from the Earth's core  causes convection currents in the mantle, and these cause the  plates to move around over millions of years. This movement is  often referred to as continental drift because the relative  positions of the continents change because of it.   Earth is liquid inside.

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.

Ocean Currents In this way, the ocean currents help regulate Earth's climate by facilitating the transfer of heat from warm tropical areas to colder areas near the poles. The water of the ocean surface moves in a regular pattern called surface ocean currents. On this map, warm currents are shown in red and cold currents are shown in blue. Image Credit: Windows to the Universe. The global wind patterns cause the surface currents to form in the uppers layer of the ocean. Where these winds blow in the same direction for long periods of time, large currents develop and transport vast amounts of water over long distances.

Wind Driven Surface Currents: Equatorial Currents Background The Intertropical Convergence Zone, or ITCZ, is the region that circles the Earth, near the equator, where the trade winds of the Northern and Southern Hemispheres come together. The intense sun and warm water of the equator heats the air in the ITCZ, raising its humidity and making it buoyant.

How Do Convection Currents aFFECT wEAther? Convection Currents affect the weather all over the Earth. Convection currents can affect even the smallest amount of weather, like wind. An example of this occurs when a land mass is adjacent to a body of water. When a land mass is adjacent to a body of water during the day it causes a sea breeze. A Sea Breeze happens when the

Ocean Currents Large quantities of heat can be absorbed and stored in the surface layers of the ocean. This heat is transported by ocean currents.

Currents in the Earth's System Large convection currents in the aesthenosphere transfer heat to the surface, where plumes of less dense magma break apart the plates at the spreading centers, creating divergent plate boundaries. As the plates move away from the spreading centers, they cool, and the higher density basalt rocks that make up ocean crust get consumed at the ocean trenches/subduction zones.

Mantle convection Mantle convection is the slow creeping motion of Earth's solid silicate mantle caused by convection currents carrying heat from the interior of the Earth to the surface. The Earth's surface lithosphere, which rides atop the asthenosphere (the two components of the upper mantle), is divided into a number of plates that are continuously being created and consumed at their opposite plate boundaries.

What Is Convection Vs. Conduction? Convection currents occur in the Earth's geosphere, atmosphere and hydrosphere when heat is transferred from one place to another. Heat energy moves from hot places to cold places during convection.

- What causes ocean currents? Ocean currents result from two processes - the action of wind on the surface of the water, and from variation in water temperature that causes movement- a process known as convection. Convection occurs because the oceanic waters heat up becoming less dense.

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.

Ocean Currents Surface currents are those found in the upper 400 meters (1,300 feet) of the ocean and make up about 10% of all the water in the ocean. Surface currents are mostly caused by the wind because it creates friction as it moves over the water. This friction then forces the water to move in a spiral pattern, creating gyres.ecause ocean currents circulate water worldwide, they have a significant impact on the movement of energy and moisture between the oceans and the atmosphere. As a result, they are important to the world’s weather.

- These major spirals of ocean-circling currents are called “gyres” and occur north and south of the equator. They do not occur at the equator, where the Coriolis effect is not present (Ross, 1995). There are five major ocean-wide gyres—the North Atlantic, South Atlantic, North Pacific, South Pacific, and Indian Ocean gyres. Each is flanked by a strong and narrow “western boundary current,” and a weak and broad “eastern boundary current” (Ross, 1995).
