Boundary where two tectonic plates are moving towards each other or colliding is called convergent boundary.Layer of Earth made up of the crust and upper mantle is called lithosphere.Upper part of the mantle is called asthenosphere.deepest part of the ocean; steep-sided canyon is called Ocean trench.Boundary where two tectonic plates are moving away from each other is called divergent boundary. place where one plate gets pushed under another plate is subduction zone. force that pulls objects towards the Earth is called gravity. section of the lithosphere that slowly moves over the asthenosphere, carrying pieces of continental and oceanic crust is called plate tectonics. long, underwater mountain ranges are called mid ocean range. describes how Earth's plates move and what happens when they interact with each other. The earth's plates move due to tectonic plates interaction.boundary where two tectonic plates move in opposite directions alongside each other is called transform fault boundary. idea that the world's land masses are slowing moving over time is refers to as pangae theory. magnetic qualities "frozen" into rocks when they are formed showing the direction of the magnetic field at that time is paleomagnetism circulating flow of a gas or liquid due to density differences is called convection.super-continent made of all the continents that existed millions of years ago is continental drift.

The answer would be interphase.
