400

This volcano has a gentle slope, is nonexplosive, and the lava is runny and spreads over a wide area.

What is a shield volcano?
400
These waves are also known as primary or pressure waves.
What is P Waves?
400
This is the hottest part of the Earth and is considered a hot solid iron ball.
What is the inner core?
400
This is the amount of years of our Earth.
What is 4.6 billion years?
400
Convergent, Divergent, and Transform are types of this.
What are tectonic plate boundaries?
800
This volcano is explosive with pyroclastic flow and has a short lifespan (slope is around 500 meters).
What is a Cinder Cone Volcano?
800

These waves only travel through solids and cannot travel through liquids.

What are S waves?
800
This is the outer layer of Earth and is about 50 km thick.
What is the crust?
800
This is when the diameter of a spherical object is different through the poles and at the equator (including the semi-major and semi-minor).
What is an Ellipsoid?
800

This is the scientist who thought of Pangaea (the idea of all the continents being once joined in a single huge continent).

Bonus: The hypothesis of continents once formed a single landmass, broke up, and drifted to their present locations. +100

Who is Alfred Wegener?


Bonus: What is the Continental Drift?

1200
This volcano has a long lifespan, the explosions have the greatest damage including pyroclastic flow and lava, and has a height of about 1,000-4,000 meters.
What is a Composite Volcano?
1200

These are the first waves of an earthquake to be detected and are the fastest type of seismic waves.

What are P Waves?
1200
This is made up of iron and nickel and has a liquid molten rock formation.
What is the outer core?
1200

This is the theory of when younger rocks lie above older rocks if the layers have not been disturbed.

Bonus: This is a break in the Earth's crust along which blocks of rock slide relative to one another. +100

What is superposition?


Bonus: What is Faulting?

1200

The process by which new oceanic lithosphere forms as magma rises toward the surface and solidifies.

What is Sea Floor Spreading?
1600

This is a body of molten rock deep underground that feeds a volcano.

What is the Magma Chamber?
1600

These are the slowest waves, but they do the most damage and destruction; often associated with earthquakes.

What are Surface Waves?
1600
This is the widest section of Earth and contains convection currents.
What is the mantle?
1600

This time includes the Proterozoic Eon, Archean Eon, and the Hadean Eon.

What is the Precambrian Time?
1600

This is a chain of underwater mountains that runs through the center of the Atlantic Ocean and where sea floor spreading takes place.

What is the Mid-Ocean Ridge?
2000

This is how lava flows and affects the surface of lava in different ways.


Bonus: This is a type of lava that has a high viscosity and flows slowly (wax and glassy). +100

What is Viscosity?



Bonus: Pahoehoe

2000

When locating an earthquake, this is the point on the Earth's surface directly above an earthquake's starting point.

Bonus: This is the point inside the Earth where an earthquake begins. +100
What is the epicenter?


Bonus: What is the focus point?

2000

This layer of the mantle is very rocky and solid and is the upper layer (closest to the crust).

What is the Lithosphere?
2000
This era is known as the age of reptiles (When Dinosaurs evolved and also became extinct).


Bonus: This era is the era of mammals and the current era we live in.

What is the Mesozoic Era?


Bonus: What is the Cenozoic Era?

2000

When a plate with oceanic crust collides with a plate with continental crust, and the oceanic crust sinks into the asthenosphere.
