Plate Tectonics

2. map showing the shape and elevation of the land surface using contour lines
3. the layer of granitic, sedimentary, and metamorphic rocks
6. difference in elevation between any two contour lines on a topographic map
7. the outer most layer of the Earth (lithosphere) is divided into contiguous sections (plates) that move relative to each other causing continental drift, seafloor spreading, and the formation of major physical features of the Earth’s surface
8. the outermost solid layer of the lithospheric tectonic plates under the oceans that covers much of the Earth's surface
9. the shape of the Earth’s surface and the way its physical features are arranged, especially in terms of their positions and elevations
10. plates slide past each other

1. Alfred Wegner’s explanation of continents slowly moving and changing their positions relative to one another
4. plates move together
5. plates move apart
6. map symbol showing shape and / or change in elevation on a topographic map
