Oh No! A Volcano!
This type of boundary created volcanoes by subduction of the Earth's Crust
What is Convergent Boundary?
This type of plate boundary only produces earthquakes and contains a fault line.
What is a transform boundary?
This is the point on Earth's surface directly above the earthquake's origin.
What is the epicenter?
This type of plate boundary allows magma to flow upwards, creating seafloor spreading.
What is a divergent plate boundary?
Tsunamis are possibly the result of these three events.
What are earthquakes, landslides, and volcanic eruptions?
This type of volcano is flat and is usually found on islands.
What is a shield volcano?
What is the overriding plate?
This is the wave that travels by compressing and expanding rock.
What is a P-Wave (Primary)?
The oceanic crust is this age compared to the continental crust.
What is younger?
This is the result of the water wave meeting the shore on an island or coast. This increases as the water goes from ocean to land.
What is the wave height increases?
This type of eruption is caused by the building up of magma and pressure over time. This is the type of eruption that happened at Mt. St. Helens.
What is an explosive eruption?
This is the device that measures ground motion when the tremors of an earthquake occur.
What is a seismograph?
As new oceanic crust forms at the oceanic ridge, this makes older crust do this. This can also make plane rides between continents seem a lot longer.
What is move the continental crusts away from the ridge?
This characteristic makes tsunamis hard to spot in deep water while out on a boat in the ocean.
What is low amplitude?
This type of substance expels from volcanoes in a hot, fast moving gas and volcanic matter. You would not want to get caught in this!
What is pyroclastic flow?
What is radioactive dating?
This type of earthquake happens in underground caverns and mines.
What is a collapse earthquake?
This type of banding shows the polarity the Earth had at that specific point in time.
What is magnetic banding?
The tsunami wave builds up when the water wave meets the shore line because of this force.
What is the force of friction?
This property of liquid helps explain how explosive a volcano might get. It also describes how runny or not so runny the lava is.
What is viscosity?
This process in the Earth's mantle drives plate tectonics.
What is convection currents?
This is the name of a place where high seismic activity is present around the Pacific Ocean.
What is The Ring of Fire?
This ridge is the largest and most famous ridge this is between the South American Plate and the African Plate.
What is the Mid-Atlantic Ridge?
A network of a place and this instrument helps us in predicting if a tsunami may hit a costal area.
What is seismic stations and sea-level gages?
