Geo unit 1

• Margins of plates are action locations for earthquakes and are represented on a map.
• Convection cells in the asthenosphere are represented in a cross-section view.
• Divergent Margins occur when the asthenosphere is rising, creating new oceanic crust and lithosphere.
• Mid-oceanic ridges are where the oceanic crust and lithosphere separate, forming new ocean basins.
• Rift- valleys are where the continental crust and lithosphere separate, forming new continents.
• Convergent Margins occur when the asthenosphere is sinking, destroying existing oceanic crust and lithosphere.
• Trenches are where the oceanic crust and lithosphere subduct, forming new ocean basins.
• Volcanic Island Arc or Chain is the leading edge of the over-riding plate.
• Folded Mountain Chains, such as the Himalayas, are formed by the collision of tectonic plates.
• Transform Faults are where plates sliding past one another horizontally.
• San Andres Fault is an example of a natural process where water moves from within the ocean into the atmosphere, a process called infiltration.
• The rock called "granite" is an igneous rock that erupts onto the surface to form the Earth's ocean basins.
• The existence of "natural laws" that work throughout the Universe is a "fact" based upon utilization of the scientific method.
• Basalt is an igneous rock enriched in Fe, while Granite is an igneous rock enriched in Si and contains quartz.
• In science, numbers and units are referred to as "units" and can be compared using comparisons such as "too big" or "too small" on an Exponential Scale.
• Density is represented as gm/cm3.
• Convection Cells are the redistribution of heat generated by the movement of materials of differing density due to differences in temperature.
• Plates are pieces of lithosphere moving as a coherent mass.
