What is the primary force that causes the sea floor to spread and continents to drift?

What happens in sea-floor spreading?
At mid-ocean ridges, tectonic plates move apart due to magma rising from below the Earth's crust. As the plates separate, lava flows out and solidifies, forming new oceanic crust. This process, known as sea-floor spreading, contributes to the constant renewal and expansion of the ocean floor.
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.
How does sea-floor spreading provide a way for continents to move?
because if the sea-floor is moving it will probably will move a chunk of land that could be part of a continent the land at the bottom of the ocean is being spread across, and is taking space up. the continents are on tectonic plates, and need to go some where and move away.
What causes continental plates to move?
Continental plates move due to the process of plate tectonics, where the plates float on the semi-fluid asthenosphere layer beneath them. This movement is driven by convection currents in the mantle, caused by heat from the Earth's core. When these currents push or pull on the plates, they cause them to move, leading to phenomena like earthquakes, volcanic activity, and the formation of mountains.
What happens in sea floor spreading?
under water volcanoes move the oceanic plates and spread them
What in the mantle is the force that causes the plates to move slowly over the crust?

Why does the ocean floor spread apart at the ridge?
Because as tectonic plates move away from each other, the ocean floor spreads apart and fills the gap.
What is the crack in the ocean floor in which earth rises?
those are tecktonic plates which are delicate.when they move crackes occur. when tecktonic plates move under water it creates viberations which causes tsunamis.
How does sea floor spreading make the continents move?
Under the oceanic crust is the layer of the earth called the mantle. This layer is moving rock that is very, very hot! As the hot material in the mantle pushes up through the crust in the sea floor, it cools and becomes new crust as it pushes out (spreads) the sea floor. This movement in the plates causes other plates (continental and oceanic) to move as well. This is how sea floor spreading causes continents to move.
What makes the continent and the ocean floor unstable?
The continents and ocean floor are unstable because the plates of the lithosphere move. When the plate move, they cause the continents and ocean floor to move.

What causes your plates to move?
convection currents!
What happens when the Earth's crust splits apart and forms a valley?
It causes what we call "sea-floor spreading." Sea-floor spreading is the process in which the ocean floor is extended when two plates move apart. As the plates move apart, the rocks break and form a crack between the plates. Earthquakes occur along the plate boundary. Magma rises through the cracks and seeps out onto the ocean floor like a long, thin, undersea volcano.
The movement of the ocean floor on either side of a midocean ridge is best known as?
it is known as sea floor spreading. this is when the oceanic plates diverge or move apart which causes the magma from the mantle to rise forming new sea floor.
What causes plates to stop moving temporarily?
Friction causes plates to stop moving temporarily. The motion of the magma under the plates will cause the plates to move again.
