As compared to oceanic crust, the continental crust is | Less dense and composed of Granite |
The horizontal layers of rock | Strata |
A large crack in the rock along which earthquakes occur | Fault |
Three types of plate boundaries | Divergent, Convergent, Transform |
Landforms found at divergent boundaries | Ocean Ridges |
Landforms found at oceanic to oceanic convergent boundaries | Island arcs, Ocean Trenches |
Landforms found at continental to oceanic convergent boundaries Volcanic Mountains Ocean Trenches | Volcanic Mountains, Ocean Trenches |
Theory describing Earth divided into plates that move: | Plate Tectonic Theory |
The driving force for plate tectonics | Mantle Convection |
Volcanoes that occur in the middle of tectonic plates | Hot Spots |
Sharp, Volcanic rock formed by very slow moving and thick lava | Aa |
Smooth, volcanic rock formed by fast moving and thin lava | Pahoehoe |
Explosive volcano shaped by deposits of ash and rock. | Cinder-Cone |
Quiet Volcano shaped by deposits of lava | Shield cone |
Explosive Volcano shaped by layers of lava and ash and rocks. | Composite Volcano |
Example of two continental plates colliding | Himalayan Mountains |
Hawaii is an example of a volcano caused by: | Hot Spot |
Example of Divergent boundary | Mid-Atlantic Ridge |
Example of Transform Boundary | San Andreas Fault |
Process accuring at Ocean to Continental boundaries | Subduction |
Most Earthquakes and Volcanoes occur at | Plate Boundaries |
Two main effects of plate tectonics are | Earthquakes and Volcanoes |
California sits on this type of plate boundary | Transform |
A plate boundary where two plates collide | Convergent |
A plate boundary where two plates are pulled apart | Divergent |
A plate boundary where two plates slide past one another | Transform |
Instrument that measures energy moving through Earth | Seismograph |
The place in Earth’s crust where a rock mass has moved causing an earthquake | Focus |
Fastest Earthquake waves | P-waves |
The point on Earth’s surface above the place where the earthquake originates. | Epicenter |
A large mass of melted snow and debris that runs down the side of an erupting Volcano (mud flow) | Lahars |
A ground-hugging avalanche of hot ash, pumice, rock fragments, and volcanic gas that rushes down the side of a volcano as fast as 100 km/hour or more. | Pyroclastic Flow |
A huge wave caused by an Earthquake | Tsunami |
Rock type formed by Heat and Pressure | Metamorphic |
Rock formed by Melting and Cooling | Igneous |
Rock formed by uplift, weathering, erosion, deposition and cementation Sedimentary | Sedimentary |
The breaking down of rocks | Weathering |
The moving of rock particles from one place to another | Erosion |
Depositing the rock particles | Deposition |
Examples of Erosion | Runoff, Wave Action, Water Suspension, Glaciers |
Three types of Chemical Weathering | Oxidation, Carbonation, Hydration |
The chalk in the Vinegar is an example of | Chemical Weathering |
The Brick and sandpaper is an example of | Physical Weathering, |
The Jolly Rancher sucker experiment is an example of | Chemical and Physical Weathering |
