Breaking Up is Hard to Do
New ocean crust made at mid-ocean ridges
What is seafloor spreading?
The following all have one thing in common:
Divergent plate boundaries, Convergent plate boundaries, Hotspots
What are places where volcanoes originate?
The location from which an earthquake starts
What is focus?
Earthquakes at subduction zones can often cause this event.
What is tsunami?
Earth's tallest mountain ranges have been formed by...
What is collisions between plates of continental crust?
Supercontinent that included all current land masses, that existed 200 million years ago before the continents broke apart
What is Pangaea?
The last major volcano eruption near Vancouver.
What is Mount. St. Helens eruption?
Vibrations caused by the release of energy during an earthquake.
What are seismic waves
Besides earthquakes, tsunamis can be caused by these 2 other under-water events.
What is volcanic eruption and landslide?
The tallest mountain range on Earth.
What are the Himalayas?
When two plates move together or towards each other.
What is a convergent boundary?
Hot regions of Earth's mantle where magma rises to the surface by breaking through weak parts of the lithosphere.
What are hot spots?
This type of seismic wave travels through both solids and liquids
What is primary wave?
A tsunami behaves in this way as it approaches shore.
What is slows down and increases in height?
Many peaks grouped together in a continuous line- 100 to 1000 km long.
What are mountain ranges?
Current in the mantle where cooler, denser material sinks and warmer, less dense material rise.
What is mantle convection?
This island or group of islands is formed by a hot spot.
What is Hawaiian Islands?
This is measured with the Richter scale and refers to how strong an earthquake is.
What is magnitude?
The country most affected by the tsunami in 2011 that destroyed nuclear reactors and caused thousands of deaths and immense destruction.
What is Japan?
This evidence at the top of mountains supports that those rocks were formed at the bottom of seas, oceans or lakes.
What are fossils of aquatic lifeforms?
A mid-ocean ridge, a divergent tectonic plate located along the floor of the Atlantic Ocean, and part of the longest mountain range in the world.
What is the Mid-Atlantic Ridge?
Erupted lava and volcanic ash at convergent oceanic-oceanic boundaries form this over time.
What is arc-shaped group of volcanic islands?
The slowest and most damaging of the three earthquake waves?
What are surface waves?
This should be your immediate response when notified of an imminent tsunami.
What is move to higher ground?
The Himalayan Mountain Range is thought to have formed from a collision between these two plates.
What are the Indian and Eurasian plate?
