Layer of earth made up of the crust and upper mantle long, underwater mountain ranges idea that the world's land masses are slowing moving over time magnetic qualities "frozen" into rocks when they are formed showing the direction of the magnetic field at that time describes how earth's plates move and what happens when they interact with each other circulating flow of a gas or liquid due to density differences force that pulls objects towards the earth boundary where two tectonic plates are moving away from each other boundary where two tectonic plates are moving towards each other or colliding upper part of the mantle that boundary where two tectonic plates move in opposite directions alongside each other place where one plate gets pushed under another plate deepest part of the ocean; steep-sided canyon super-continent made of all the continents that existed millions of years ago section of the lithosphere that slowly moves over the asthenosphere, carrying pieces of continental and oceanic crust 1. lithosphere 2. asthenosphere 3. convergent boundary 4. divergent boundary 5. transform boundary 6. mid-ocean ridge 7. ocean trench 8. paleomagnetism 9. continental drift 10. plate tectonics 11. convection 12. gravity 13. tectonic plate 14. subduction zone 15. pangaea all you gotta do is just number the following sentence that is given. and of course be sure to answer the questions in the correct manner. first one to answer gets
