Continential Drift+ SEAFLOOR SPREADING+MORE EARTHQUAKES
How high does the richter scale go?
What is an focus?
The point beneath Earth’s surface where rock breaks under stress and causes earthquake.

At what time did Albert Wegner make his theory about the Continential Drift?
He made it around 1912-1929
What is a tetonic plate?
Example: There is 3 plates that are slowly moving, causing earthquakes along the way.
Did Henry Hess, and Alfred Wegener work together.
NO!
Who came up with the theories?
Albert Wegner, and Harry Hess.
What is an epicenter?
The point on Earth’s surface directly above an earthquake’s focus.
What is the Continential Drift?
The landmass moving because of seafloor spreading.
What is an fault line?
A break in Earth’s crust where masses of rock slip past each other.
What is an volcano?
A weak spot in the crust where magma has come to the surface.
How many earthquakes are predicted to happen each year?
500,000
What causes an earthquake?
What is seafloor spreading?
A trench pushing away rock and filling up with new rock made with mantle material.
What are the three plates?
Convergent, Transform, and divergent boundaries.
What are the members of the group.
Grant- 149 points if you guessed him.
Derrick-150 points if you guessed him.
Ayan- 1 point if you guessed him.
JK! YOU MUST GUESS THEM ALL TO RECIEVE CREDIT.
What are the four fault lines?
Normal, reverse, strike-slip, dip-slip
Do volcanoes cause earthquakes?
Some, but not all, earthquakes are related to volcanoes. For example, most earthquakes are along the edges of tectonic plates. This is where most volcanoes are too. However, most earthquakes are caused by the interaction of the plates not the movement of magma.
Who had a theory that the land kept moving. (Seafloor Spreading Thingy)
Albert Wegner
What is an plate boundary
A section of the lithosphere that slowly moves over the asthenosphere carry pieces of continental and oceanic crust.
What is magma?
The molten mixture of rock-forming substance, gases and water from the mantle.
How is new rock formed?
What was the most destructive earthquake on the richter skill.
The most powerful quake was the 9.5-magnitude Valdivia Earthquake that struck in Chile in 1960. That quake created a tsunami, which together killed an estimated 5,700 people.
The scientist that helped discover the process of seafloor spreading.
Who is Henry Hess
What was Pangaea.
The name of the single landmass that broke apart 200 million years ago, and gave rise to today’s continents.
When was Albert Wegner's Birthday?
It was on November 1, 1880.
