Convection in the Earth's crust is driven by heat from the Earth's molten core. This heat causes the mantle to convect, which in turn can move the Earth's tectonic plates. As the plates move, they can interact through processes such as subduction, causing earthquakes and volcanic activity.

How do you think the convection cell might affect the earths crust?
Convection cells in the Earth's mantle can drive the movement of tectonic plates, which in turn can affect the Earth's crust through processes like subduction, where one plate is forced beneath another. This movement can cause earthquakes, volcanic activity, and the formation of mountain ranges as plates collide or separate.
What is beneath the earths crust that circulates like a conveyor belt?
The mantle is beneath the earth's crust, and it circulates in a process known as mantle convection. This convection is driven by the heat from the Earth's core, causing molten rock to move in a circular motion, much like a conveyor belt.
What is the name of the long deep valleys that are formed by the movement of Earths crust?
rift valleys
Compared to earths continental crust earths oceanic crust is?
Earth's oceanic crust is thinner, denser, and younger than Earth's continental crust. It is primarily composed of basaltic rock, whereas continental crust is made up of less dense granitic rock. Oceanic crust is constantly being formed at mid-ocean ridges and destroyed at subduction zones.
If convection in the mantle increased how would the earths crust be affected?
An increase in mantle convection could lead to changes in plate movement and potentially result in more frequent and intense volcanic eruptions and earthquakes on the Earth's crust. This could also lead to the formation of new crust (via seafloor spreading) or the consumption of crust (via subduction), altering the tectonic landscape.
What is formed through the uplift under the earths crust?
crust
What pulls the earths crust?
The earths crust is moved rather than pulled by things called convection currents. This is when heated rock from the earths core rises up and reaches the crust where it cools. It then sinks down again and carries on in a circle which moves the crust
Which of earths layers is formed by volcanic activity?
Crust
What twists tears or pushes part of the earths crust past another?
convection currentsShear
Convection currents in the earths crust causes volcanos?
No. Earth's crust does not convect. Convection in the mantle, however can create hot spots and rifting, which can lead tot he formation of volcanoes.
Which of these is formed when plates of earths crust bend and crack?
a fault
Which forces responsible for earths crust and lithosphere floating on the mantle?
convection currents in the upper mantle
Why is the earths crust always moving?
Simple- Convection in the mantle causes mantle to slowly move, and it pushes against the crust. As it does this, the tectonic plates move.
What is formed as plates within earth bend and crack earths crust?
magma
What forms valcanoes?
most volcanoes are formed from a hot spot in the earths crust.
What is the name of the long deep valleys that are formed by the movement of the earths crust?
rifts
