Other Stuff
100
THIS is the widest section of the Earth. It has a thickness of approximately 2,900 km. It is made up of semi-molten rock called magma. In the outer parts, the rock is hard, but the inner parts, rock is soft and beginning to melt.
What is the Mantle?
100
THESE are the three types of Plate Boundaries.
What are the Convergent, Divergent, and Transform boundaries?
100
THIS is the main area from which lava will erupt from volcano.
What is the main vent?
100
Earthquakes are mainly caused by movement on THESE plate boundaries (name all that apply).
What are Convergent and Transform plate boundaries?
100
The power of an Earthquake is measured by THIS.
What is the Richter Scale?
200
The outer layer of the Earth, mostly made up of Granite.
What is the Continental Crust?
200
When two plates collide, eventually, the densest of the two will generally do THIS.
What is Subduct?
200
THIS is Volcanic Ash, Lava, Rock, and Gases all caught up in a cloud of Ash!
What is Pyroclastic Flow?
200
An earthquake is the result of a sudden release of stored energy in the Earth's crust that creates THESE.
What are Seismic Waves?
200
THIS is the largest of the volcanoes. It continually oozes slow-moving lava. So slow, in fact, that humans can walk away from it often times.
What is the Shield Volcano?
300
THIS is the solid outer section of Earth, which includes Earth's crust (the "skin" of rock on the outer layer of planet Earth), as well as the underlying cool, hard upper part of the upper mantle. It makes up the TECTONIC PLATES of the Earth’s surface!
What is the Lithosphere?
300
Continent to Continent plate boundaries typically form THIS physical feature.
What are fold mountains?
300
THIS volcano has the most explosive, violent eruptions due to its thick and viscous (sticky/gooey) magma that slowly builds up underneath a small crater. Pressure coming from both gas in the magma and the pressure pushing against blockage at top of crater builds until it explodes.
What is a Composite Volcano?
300
Tsunamis are mainly caused by THIS type of Plate Boundary movement. Be specific.
What is Oceanic to Oceanic Convergent Plates?
300
THIS is the area impacted most by an Earthquake on the surface of the Earth!
What is the Epicentre?
400
THIS carries the extreme heat near the outer core of the Earth to the asthenosphere. When the rock cools in the asthenosphere, it sinks back to the bottom and heats up again (moving around and around).
What is a Convection Current?
400
THIS is an underwater mountain range formed by plate tectonics. This uplifting of the ocean floor occurs when convection currents rise in the mantle beneath the oceanic crust and create magma where two tectonic plates meet at a divergent boundary.
What is a Mid-Ocean Ridge?
400
THIS volcano is known for its runny and gassy lava that create fast, short, repetitive, explosive eruptions.
What is a Cinder Cone volcano?
400
During an Earthquake, the spot where the plates give way is THIS and the spot on the surface directly above is THIS.
What are the FOCUS and the EPICENTRE?
400
THIS is why the west coast of South America is susceptible to earthquakes and volcanoes. Explain.
What is the effects of Oceanic to Continental Convergent Boundaries?
500
THIS is the layer of the Earth that lies below the lithosphere. It is a layer of rock that has so much pressure and heat the rocks can flow like a liquid.
What is the Asthenosphere?
500
THIS is the specific Plate Boundary in the image below:
What is Continent to Oceanic Convergent Boundary?
500
THESE are the plate boundaries along which volcanoes form.
What are Oceanic to Continental Plate Boundaries, and Divergent Plate Boundaries?
500
As the water displaced by a plate movement under the ocean's surface moves closer and closer to land, it turns into a Tsunami because of THIS.
What is Lack of Space for the water to push into? (As the waves push outward, the back of the waves are moving faster than the front, so as they approach land and there is less and less space for all of the water, the back rises causing a massive wave to form)
500
An earthquake is caused by THESE getting stuck and putting huge amounts of strain on each other. The strain becomes so great that rocks give way by breaking and sliding along the THIS.
What are Tectonic Plates and the Fault Line?
