What is Lithosphere, Mesosphere, and Centrosphere?
100
Igneous rock that has reached the surface of the Earth.
What is Lava?
100
Violent shaking of the Earth's surface caused by a sudden displacement of subsurface rock masses.
What is an Earthquake?
100
The solid outer crust of the Earth.
What is Lithosphere?
100
________ ________ came up with the theory of the Continental Drift and the super continent that he called Pangea.
Who is Alfred Wegener?
200
At this crack plates are moving horizontally, grinding against each other as they move in opposite direction.
What is transform fault?
200
Mt. Baker is this kind of Volcano.
What is Composite Volcano?
200
Located on the surface directlty above the surface point.
What is Epicentre?
200
Water heated by magma close to the surface that finds an escape route through cracks in the Earth's crust.
What is Hot Spring?
200
Most earthquakes in the world occur along thousands of kilometers of _______ ________.
What is Plate Boundries?
300
List 3 types of Plate Movement.
What is divergence, convergence, tear or strike-slip?
300
Igneous rock moves towards the surface, it's path often will be across rock layers. The rock layer through which the magma is moving is fractured and creates this feature.
What is a Dike?
300
The distance between the focus and the epicentre, which varies greatly from one quake to another.
What is Focal Depth?
300
One of the three main rock types. Created when sediment collects in low lying areas, is slowly pressurized and compacted into layered rock.
What is Sedimentary Rock?
300
Powerful convection currents in the __________ are the driving force that propels the plates at a rate of 2-3cm per year.
What is Asthenosphere?
400
Another name for Continental Crust, and Oceanic Crust.
What is Sial, and Sima?
400
List 3 types of Volcanoes.
What is Shield Volcanoes, Cinder Cone Volcanoes, and Composite Volcanoes?
400
Shock waves generated by earthquakes. List 3.
What is compression/primary wave, shear/secondary wave, surface wave.
400
Crack in the Earth where only horizontal movement of rock occurs. Also known as transform fault, strike-slip fault.
What is Tear Fault?
400
Millions of years earlier this land was formed at the mid-ocean ridge. This area of collision between the two plates, is commonly marked by an ______ _______, as the driving plate pulls down the leading edge of the plate is has come up against.
What is Ocean Trench?
500
Evidence that supports the theory of Continental Drift.
What is Coastline fit, Geological fit, Paleoclimatology, and Fossil correlation?
500
List features created by extrusive volcanic activity.
What is Pyroclastics, Caldera, Lahars, Nuees Ardentes?
500
1. Fault is locked; rock under stress; elastic defomation occurs. 2. Stress + elastic deformation continues 3. Fault slips; pressure released -- EARTHQUAKE!
What is Elastic Rebound?
500
A mass of intrusive igneous rock. Sometimes covers thousands of square kilometers. If erosion removes overlying layers, THIS is exposed.
What is Batholith?
500
Weathering and erosion break apart the _____ _____ and transport small particles to low lying areas, such as continental shelves, where compaction and cementaion take place to create ________ _______. With heat and intense pressure, this kind of rock may change to the third type of rock known as _______ ________.
What is Igneous Rock, Sedimentary Rock, and Metamorphic Rock?
