What feature do newly erupted central and lateral incisors have on their incisal ridge?
mamelon
What a ridge push?
Ridge push is a gravitation force that causes a plate to move away from the crest of an ocean ridge, and into a subduction zone.
Which of these is a boundary where two tectonic plates move away from each other leaving a newly constructed ridge in between?
divergent
What are the three processes that cause tectonic plates to move?
Three processes that contribute to the motion of tectonic plates are convection currents, ridge push, and slab pull. Convection currents is when the mantle rises, cools, sinks and heats, then rises and repeats the cycle. Ridge push is a gravitational force that causes a plate to move. Slab pull is the movement of tectonic plate lithosphere due to convection currents in the asthenosphere.
What is a boundary where two tectonic plates move away from each other leaving a newly constructed ridge in between?
divergent boundary
What is a ridge push?
Ridge push is a geological concept where the force of gravity causes oceanic lithosphere to move downhill from a mid-ocean ridge, pushing tectonic plates away from the ridge. This process contributes to plate motion along with other forces like slab pull and mantle convection.
Why does the lithosphere thicken away from the ridge crest?
Cooling as rock moves away from the ridge crest causes the rock to become increasingly rigid.
What is the difference between ridge push and slab pull?
Ridge push is a gravitation force that causes a plate to move away from the crest of an ocean ridge, and into a subduction zone. The Slab pull force is a tectonic plate force due to subduction. The difference is the force of motion.
What causes earthquakes volcanoes trenches mid-ocean ridge?
Plate tectonics.
What causes the oceanic lithosphere to move away from the mid-ocean ridge?
it is caused by convection currents
What are some causes for the changing of Earth's surface?
plate tectonics, mid ocean ridge
