divergent - correct answer ✔_______________ boundaries occur where
lithospheric plates are moving away from one another.
slab pull - correct answer ✔the primary mechanism responsible for most of
the plate movement in plate tectonics is
convergent - correct answer ✔what kind of boundary is present between the
two arrows
between the boundaries - correct answer ✔tectonic plates are the spaces...
edges separating the plates - correct answer ✔tectonic plate boundaries are
the...
slab pull - correct answer ✔when plates of different densities converge the
edge of a denser plate pulls down to melt (like the edge of a hanging wet
towel)
ridge push - correct answer ✔the process in which new material at a ridge or
rift pushes older material aside, moving the tectonic plates away from the
ridge
seafloor spreading - correct answer ✔the process that creates new sea floor
as plates move away from each other at the mid-ocean ridges
continental crust - correct answer ✔oceanic crust is denser than...
, mid-ocean ridge - correct answer ✔an underwater mountain chain where

the relationship between age and the character of the ocean floor, which
statement(s) is (are) true?
athenosphere - correct answer ✔the upper layer of the earth's mantle, below
the lithosphere, in which there is relatively low resistance to plastic flow and
convection is thought to occur.
