What else can I help you with?
What do geologist believe is the driving force for sea floor spreading?
convection currents in the mantle.
What forces sea floor spreading?
Sea floor spreading is caused by convection currents in the mantle to cause a divergent boundary underwater. When the divergent boundary spreads, it caues a mid-ocean ridge. This is sea-floor spreading. Hope I helped!
What are the names of the region in earth's interior where convection currents occur?
The region in Earth's interior where convection currents occur is called the mantle. Convection currents in the mantle are responsible for driving plate tectonics and shaping Earth's surface features through processes like subduction and sea-floor spreading.
What causes the plates to move and the sea floor to spread?
Convection Currents: The difference in temperature between the upper and the lower mantle creates these currents that causes magma to rise up through the mantle and out the crust.
What cause a new sea floor to be created and how is it created?
Sea floor spreading causes this. As the floor spreads apart new magma is being pushed up through the ridge from the mantle through convection currents. It's like a recycling system.
What is the primary force that causes the sea-floor to spread?
Convection currents
What causes the hot materials beneath ocean floor to move?
Convection currents.
How do convection currents drive the process of sea floor spreading?
The hot materials like magma goes up and the cool materials like water goes down . As all magma cools, it became land because it was cooled by water but other magma goes down on and goes back to the flow. The way of the magma goes bigger and water comes in (what we called trench) and causes the seafloor spreading.
What mechanism moves lithospheric plates?
The movement of lithospheric plates is primarily driven by the process of plate tectonics. This movement is caused by the heat-driven convection currents in the Earth's mantle. As these currents circulate, they drag the overlying lithospheric plates along with them, causing the plates to move over time.
The primary force that causes sea floor to spread?
Sea floor spreading is primarily caused by the movement of tectonic plates away from each other at mid-ocean ridges. As the plates move apart, magma from beneath the Earth's crust rises to fill the gap, solidifies, and creates new oceanic crust. This process of continuous creation of new crust and the movement of tectonic plates leads to the spreading of the sea floor.
What is the cycle of convection currents in Earth?
convection currents r a cycle of heat in the mantle. the energy is produced by the heat in the core. the heat rises it becomes cooler and has a greater density. when the desity starts to decrease, it gets hotter and goes round and round in the cycle for many years. but, when the heat is on the top and it rises, the mantle can open up and cause sea floor spreading to occur.
Seafloor spreading is caused by what?
Convection currents within earth's mantle are responsible for both continental drift and sea floor spreading. The heat driving these currents comes largely from the decay of long lived isotopes trapped in earth's core and mantle.
