Transform boundaries are
a place where two plates move apart
a place where two plates come together
a plate where two plates slip past each other, moving in opposite directions
a layer of hot, solid material between Earth's crust and core
Convergent boundaries are
a place where two plates move apart
a place where two plates come together
a plate where two plates slip past each other, moving in opposite directions
a layer of hot, solid material between Earth's crust and core
Divergent boundaries are
a place where two plates move apart
a place where two plates come together
a plate where two plates slip past each other, moving in opposite directions
a layer of hot, solid material between Earth's crust and core
Subduction is
a deep underwater canyon where the oceanic crust slowly sinks toward the mantle
an undersea mountain chain where new ocean floor is produced
a section of the lithosphere that slowly moves over the asthenosphere carrying the Earth's crust
a process in which ocean floor sinks beneath a deep ocean trench and back to the mantle
Mid-ocean ridges are
a deep underwater canyon where the oceanic crust slowly sinks toward the mantle
an undersea mountain chain where new ocean floor is produced
a section of the lithosphere that slowly moves over the asthenosphere carrying the Earth's crust
a process in which ocean floor sinks beneath a deep ocean trench and back to the mantle
Deep ocean trenches are
a deep underwater canyon where the oceanic crust slowly sinks toward the mantle
an undersea mountain chain where new ocean floor is produced
a section of the lithosphere that slowly moves over the asthenosphere carrying the Earth's crust
a process in which ocean floor sinks beneath a deep ocean trench and back to the mantle
