As I'm sure you know if you asked "how," convection currents are the cycle of hotter matter rising, then falling as it cools down. In the earth, as the mantle, which is quite soft/fluid-like, heats near the core, it rises toward the surface - the crust. Near the crust, it is much cooler than the 2520-5400*F mantle, and the matter of the mantle falls.
Because the tectonic plates lie on top of the mantle, the movements inside the Earth move the plates as well, causing the tectonic movement that is observed over milennia.
What else can I help you with?
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.
How does convection currenctions work inside the earth?
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 the earths surface is made up of tectonic plates. These plates move due to convection currents.
What effect does convection currents in the upper mantle have on the crust?
Convection currents in the mantle create plate tectonics.
Convection currents cause the crust of the Earth to move?
Convection currents in the mantle transfer heat, causing the movement of tectonic plates above. This movement results in phenomena such as earthquakes, volcanoes, and mountain building as plates collide, separate, or slide past each other. The crust itself is not responsible for the movement, but rather is driven by the convection currents in the underlying mantle.
What are some effects convection currents have on the world?
Convection currents inside the Earth happens. The part where the convection currents go up, it brings up materials from the mantle like rocks. This forms new crust. When the convection currents go down, it brings down some older, colder oceanic crust to the mantle, destroying it. In conclusion, the crust is formed and destroyed when convection currents inside the Earth happen.
How does the convection currents cause te crust of the Earth to move?
Because the convection currents involve the Earth's crust.
Is the Earth's crust is in motion?
Convection currents of heat underneath the earth's crust in the mantle (magma) cause the tectonic plates of the earth's crust to move.
Why is the Earth's crust in constant in motion?
Convection currents of heat underneath the earth's crust in the mantle (magma) cause the tectonic plates of the earth's crust to move.
Why is earth's crust in constant motion?
Convection currents of heat underneath the earth's crust in the mantle (magma) cause the tectonic plates of the earth's crust to move.
What moves the Earth's crust?
Convection currents.
What moves earth crust?
Convection currents.
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 do scientists that convection currents flow through?
Scientists believe that convection currents flow through the Earth's mantle, which is the layer of hot, flowing rock beneath the Earth's crust. These currents are driven by heat from the Earth's core and cause the movement of tectonic plates at the surface.
Do convection currents affect the movement of plates on Earth's crust?
Yes!
Why is the earth's crust in constant motion?
The Earth's crust is in constant motion because of plate tectonics. The movement is driven by heat and convection currents in the Earth's mantle, which causes the rigid outer layer to break apart and move around. This movement leads to the formation of mountains, earthquakes, and volcanic activity.
How does the crust affect earth?
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.
