Convection currents in the Earth’s crust cause volcanoes.

True or False

It's false, purely because the crust in the Earth are cold and brittle, and that prevents the convection currents, which represent one of the three main types of heat transfer, to appear. Moreover, when this temperature difference exists, we can say that hot fluids rise and cold fluids sink, and then currents, or movements are created.

It is false that convection currents in the Earth’s crust cause volcanoes .
Volcanoes are largely caused by convection currents in the Earth's mantle, not by its crust . Under the crust, in a hot, semi-fluid rock layer, is the Earth's mantle .
The heat produced by the core creates convection currents in the mantle, which cause hot material to rise and cooler material to sink.
The movement of tectonic plates on the surface of the Earth is caused by a process known as mantle convection .
Volcanoes often develop near plate boundaries, where tectonic plate interactions cause magma ( molten rock ) to rise to the surface through fractures or vents in the crust.
Therefore, rather than the crust itself, the convection currents in the mantle are what are largely responsible for the eruption of volcanoes.
Thus, the given statement is false .

The statement is False because convection currents occur in the mantle, not the crust, and volcanoes are formed due to tectonic activity at plate boundaries. The mantle's convection drives the movement of tectonic plates, which can result in volcanic eruptions when cracks in the crust allow magma to rise. Thus, it is the relationship between mantle convection and tectonic plate movements that leads to volcano formation, not convection in the crust itself.
