Because convection currents is the heating rising cooling process and if the crust and part of the upper mantle wasn't divided into sections the heated material couldn't rise up.

What else can I help you with?
Are plate tectonics caused by convection currents in the mantle?
That is the current theory of plate tectonics.
What layer of Earth can you find convection currents?
Convection currents can be found in the mantle layer of Earth, specifically in the asthenosphere. These currents are responsible for driving tectonic plate movements and are a key component of the process of plate tectonics.
How does convection current relate to plate tectonics?
Convection currents in the mantle drive the movement of tectonic plates by transferring heat and causing the plates to move across the Earth's surface. As the hot mantle material rises and the cooler material sinks, it creates a circular motion that drives the lateral movement of tectonic plates. This process is known as mantle convection, which plays a significant role in the theory of plate tectonics.
What powers the plate tectonics?
The plate tectonics are powered by the heat generated from the Earth's core. This heat causes the movement of molten rock in the mantle, creating convection currents that drive the movement of tectonic plates over the Earth's surface.
In which of earths layers do convection currents happen?
Convection currents occur in the mantle, which is the layer beneath the Earth's crust. These currents are responsible for the movement of tectonic plates and play a key role in shaping the Earth's surface through processes like plate tectonics and volcanic activity.
Are convection currents related to plate tectonics?
A version of convection currents, occurring in the mantle, is thought to be the force behind plate tectonics.
Are convection currents the cause of plate tectonics?
true
How do earths convection currents move?
from plate tectonics
Are plate tectonics caused by convection currents in the mantle?
That is the current theory of plate tectonics.
If convection currents did not exist would plate tectonics still move?
NO
Who discovered the idea of plate tectonics and convection currents?
alfred wagner
How is the rock cycle related to the movement of earth's plate?
convection currents convection currents convection currents
How does the crust affect earth?
Convection currents in the mantle create plate tectonics.
How Does the Mantle Affect the Earth's Crust?
Convection currents in the mantle create plate tectonics.
Explain plate tectonics and the mechansim of continental drift?
Plate tectonics describes the motion of the Earth's lithosphere which brings about continental drift due to convection currents.
What layer of Earth can you find convection currents?
Convection currents can be found in the mantle layer of Earth, specifically in the asthenosphere. These currents are responsible for driving tectonic plate movements and are a key component of the process of plate tectonics.
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.
