Rock Types
That's the third rock type, the other two being Metamorphic and Sedimentary
What are Igneous rocks?
Geologists can take a look at the layers of rock faces and tell that lower layers are also this.
What is older?
This kind of boundary involves one plate sliding under another plate.
What is a Subduction Zone?
Also accept convergent boundary
This is the most common cause of Tsunamis.
What are underwater Earthquakes?
Engineers have these two general tools to minimize the frequency and severity of disasters.
What are adaptation and mitigation?
This type of rock forms under pressure caused by sand and other sediments building up over time.
What are sedimentary rocks?
What are Lead and Uranium.
Or Carbon and Nitrogen
This scientist was the first to realize that Earth's continents were moving.
Who was Alfred Wegener?
This is where you should go immediately after the shaking of an Earthquake ends in case a tsunami follows
Or at least a mile inland
The process can cause soil to become unstable, sinking buildings even with sturdy foundations.
What is Soil Liquefaction?
This type of rock forms from the other two rocks, under immense heat and pressure.
What is Metamorphic?
This is the age of the Earth.
What is 4.54 Billion Years?
What is a Divergent plate boundary?
This causes the waves of a tsunami to lose speed and gain wave height
What is friction between against the ocean floor?
Engineers can add these mechanisms to buildings in order to minimize the damage caused by an ongoing earthquake.
What are Base Isolators and Tuned Mass Dampeners?
This type of rock's name means "Born of Fire" and forms when lava cools rapidly
What are Igneous rocks?
These rocks, commonly found in New Zealand, were used to help approximate the age of the Earth.
What is Zircon?
As we travel deeper into the earth, this happens to the density of the material.
What is increases?
This year had what scientists believe to be the deadliest tsunami in recorded history
What is 2004?
"Galloping Gertie" was the original Narrows Bridge, which collapsed because the wind changed direction at the bridge's this.
