Earth's Internal structure
Gives the internal structure of earth.
Crust, Mantle, inner core and outer core
The proponent of Seafloor Spreading.
Harry Hammond Hess
It is a two plates that move apart
Divergent Boundary
It is a wave that travel along surface and generate earthquake.
Seismic Waves
Sudden release of energy and cause the vibration of the earth
Earthquake
2 types of crust
Continental and oceanic crust.
A geological area where one tectonic plate slides beneath another, typically an oceanic plate sliding beneath a continental or another oceanic plate.
Subduction Zone
It is a movement of plates toward each other.
convergent boundary
What is formed after the collision of two continental crust?
Mountain Ranges
It is where the earthquake originate
Focus
It is where the convection of molten rock happens below the lithosphere.
Asthenosphere
Long, high, and continuous, chains of mountains.
Oceanic ridges
It is a type of collision between two lands
Continental to Continental boundary
What is formed after the converging of oceanic and continental crust ?
Volcano
The point of earth's surface directly above the focus
Epicenter
It is the mechanism that mantle moves the tectonic plates.
Conviction Current
Rocks near the mid ocean ridges are_____ than those farther from the ocean ridge.
Younger
A long narrow depression at the bottom of oceans.
Trench
Occurs when a plume of unusually hot magma rises from deep within the Earth's mantle and melts through the overlying crust, forming volcanoes.
Hotspot
Two types of seismic waves
Body waves and Surface waves
The proponent of theory of supercontinent.
Name of the supercontinent.
The title of the theory.
Alfred Wegener
Pangaea
Continental Drift Theory
What materials that fill on the gap in the mid-ocean ridges
Magma
San Andreas fault in California is an example of what type of boundary?
Transform boundary
Two major seismic belt
Alpine-himalayan and Circum Pacific belt
Two types of surface waves
Rayleigh and love waves
