in the asthenosphere, which is in the lower part of the mantle, magma churns in a convection current which is like a cycle. Tectonic plates sit above this movement in the lithosphere. This is what causes continents to move little by little. Hot magma rises and at the lithosphere, it cools and falls because it is now denser. This is like a circular movement, or convection current.

Convection currents in the mantle are created by the heat generated from the Earth's core. Heat causes the mantle to become less dense and rise towards the surface, where it cools and becomes denser, leading to its descent back towards the core. This cyclical movement of hot, less dense material rising and cooler, denser material sinking generates convection currents within the mantle.

What effect does convection currents in the upper mantle have on the crust?
Convection currents in the mantle create plate tectonics.
How do the mantle's convection currents move to form a mid-ocean ridge?
The mantle's convection currents move in the mantle in the form of magma which creates the mid-ocean ridge. Mid-ocean ridges are found in every ocean in the world and when the currents erupt as lava the eventually cool and create a crust.
How thick are the convection currents?
Convection currents can vary in thickness, typically ranging from a few centimeters to kilometers depending on the scale of the system in which they occur. In the Earth's mantle, for example, convection currents can be tens to hundreds of kilometers thick.
Convection currents within the Earth cause plate tectonics due to the movement of the mantle true or false?
No. Convection currents which could lead to volcanism in the crust occur in the mantle. The crust is too cold and brittle for convection currents to occur.
What are effects of connection currents in the mantle?
The flow of mantle effects convection currents in the mantle. This process happens as hot material within the mantle begins to rise. As it rises, it begins to cool and then sinks. This process repeats as a cycle of convection currents.
How Does the Mantle Affect the Earth's Crust?
Convection currents in the mantle create plate tectonics.
Where do convection currents flow in Earth?
Convection currents flow in Earth's mantle, which is the layer of rock beneath the Earth's crust. These currents are responsible for the movement of tectonic plates and the formation of features like mountain ranges, volcanoes, and earthquakes.
What effect does convection currents in the upper mantle have on the crust?
Convection currents in the mantle create plate tectonics.
Where in the earth do convection currents occur?
Convection currents occur in the Earth's mantle, which is the layer beneath the Earth's crust. These currents are responsible for driving the movement of tectonic plates on the Earth's surface, leading to phenomena like earthquakes and volcanic activity.
How does the crust affect earth?
Convection currents in the mantle create plate tectonics.
How thick are the convection currents?
Convection currents can vary in thickness, typically ranging from a few centimeters to kilometers depending on the scale of the system in which they occur. In the Earth's mantle, for example, convection currents can be tens to hundreds of kilometers thick.
The layer in which convection currents move?
Convection currents move in the Mantle.
The driving forces of tectonic plates are related to convection currents in Earth's?
mantle.
How are convection currents in the mantle and in the oceans similar How are they different?
The ocean currents are colder than the currents in the mantle,and the are located in different areas.
How do the mantle's convection currents move to form a mid-ocean ridge?
The mantle's convection currents move in the mantle in the form of magma which creates the mid-ocean ridge. Mid-ocean ridges are found in every ocean in the world and when the currents erupt as lava the eventually cool and create a crust.
Which layer of the earth is the place where convection occurs?
Convection occurs in the mantle, which is the layer beneath the Earth's crust that is in a semi-molten state. This convection is responsible for the movement of the tectonic plates due to the heat generated by the core.
Is the heat source for the convection currents in the mantle for the sun?
The difference in temperature and density is the cause of convection currents in the earths mantle. Convection currents are the flow that transfers heat within a fluid.
