superposition - The principle that any given rock layer is probably older than those above it and younger than those below it continental crust - Extends from surface of Earth down to 20-30 miles. Continental crust (granite) is less dense then ocean crust (basalt). oceanic crust - Extends down from the surface of the Earth to 7 miles. Crust is layered and very uniform. Composed of basalt. mantle - Contains most of Earth's mass. Composed of iron, magnesium, aluminum, and siliconoxygen comp...

Which tools do we use to directly measure plate motion? - -Global Positioning System (GPS) satellites -Lasers Mid-ocean ridges are broad, symmetrical ridges that cross - ocean basins Tectonic plates are composed of - the lithosphere, earth's strong outer layer Subduction on both sides of the ___ produces the Ring of Fire. - Pacific Ocean Which of the following are tectonic settlings in which regional mountain belts form? - -subduction zones -continental collisions -mantle upwellings T...

Praxis 5005 science latest 2023 graded A Plate tectonics Theory that explains the movement of the continents and changes in the crust caused by internal forces Plates Blocks of the crust and upper mantle Lithosphere Plates of Earth's crust and upper mantle that are broken into the nine large plates Divergence Creates new oceanic crust when hot mantle rises and separates Convergence Oceanic crust collides with another plate, making a trench and volcanic activity. OR 2 continent plates collid...

List the 3 main layers of the earth from the center to the outside based on composition (what they are made out of). - Answer-1). Core (Inner and outer)-solid inner liquide outer. Iron/nickel alloy. Extreme pressure 2).Mantle-82% of the earth's volume-Solid, rocky, shell 3). Crust (Oceanic-younger rocks and Continental-granite rocks) List the 5 mechanical layers of the earth (based on how they deform?) Whic layers is a liquid? - Answer-1.The lithosphere is the outermost mechanical layer a...
