From what I know, Geologists have two main theories on why plates move.
-The First idea is that at converging plate margins (constructive) as material moves up, the plates are pushed outwards
-The second idea is that convection currents within the asthenosphere, (below the plates) which push plates along as if they were on wheels. These currents are formed as partially melted rocks rise because they are heated because it is hotter closer to the core and hotter materials rise. However, after rising for a while, the material cools and drops down again. This forms circular movements of rock which push the plates along.
According to these theories, gravity doesn't but there might be another theory which says otherwise.
Gravitational Sliding:
Plate motion is driven by the higher elevation of plates at ocean ridges. As oceanic lithosphere is formed at spreading ridges from hot mantle material,it gradually cools and thickens with age (and thus distance from the ridge).
Plate motion is due to convection currents in the Earth's mantle.
It is correct gravity pulls plates down toward the mantel. Convection currents in the mantel also push and pull on the plates
they helped figure out tha newton law of gravity
Gravity, of course has a central role in formation of planets. It's believed that the planets origin can be traced to the debris swirling around a young star. The term used for coming together of particles or bodies and joining together is 'accretion'. Gravity is the reason behind accretion . Small debris join together due to accretion and this accretion occurs further to give rise to larger and larger bodies like planets . Without gravity, this could never have occurred.
gravity clumped stars together, created planets and stopped everything from moving at the speed of light
eyes
yes
That's what causes them to move.
because other factors as shown in that could play a role in plate movement are ridge-push and slab-pull.
Describe how gravity inertia and friction play a role in throwing a ball
Gravity plays the central role; without gravity, there would be no such thing as an orbit.
It doesn't have a role. It is a natural phenomena
It doesn't have a role. It is a natural phenomena
It doesn't!
gravity pulls it.
It did.
is not always directly involved as the transporting medium in mass movement processes, it does play an important role
gravity
Gravity is the force that keeps galaxies and solar systems together.
