Extends to about 2900 km from the Earth’s surface

a volcanic arc that is surrounded by water.

– takes place when two plates collide

It is outer rigid part of the earth

converging continental crusts or plates which could cause shallow Earthquakes

can only travel through the surface of the earth

According to the plate tectonics model, the entire lithosphere of the Earth is broken into numerous segments called ____

causes the most damage to the structure during an earthquake

the process by which a plate dives under a less dense plate.

a vertical space that extend deep down into the lowest layer of the crust as plates pull away from each other.

a process that uses distance information from at least three seismic stations to locate the earthquake epicenter

what is the movement of lithospshere called

most of the shaking felt from an earthquake is due to this wav

caused by the force of separation of plates.

a shaking of the ground.

average thickness is 8 km, found under the ocean floor and denser than continental crust, mostly made of basalt.

a hot molten material found at the mantle.

an area below the less dense crust where a denser plate submerged.

a break or crack in a plate along which movement has occur.

move as shear or transverse wave, and force the ground to sway from side to side, in rolling motion that shakes the ground back and forth perpendicular to the direction of the waves

a series or chain of mountains that are close together

a collected record of seismic waves

What does PHILVOCS stands for?

can travel through the earth

a column of rising magma.

thickness is mostly 35-40 km, made of less dense rocks such as granite.

Which is not a Major Plate

Which is a Minor plate?

The outermost later of the lithospshere

waves of energy caused by the sudden breaking of rock within the earth or an explosion

formed when two plates move apart

– also known as the focus, the location below the earth’s surface where the earthquake starts

underwater mountain ranges.

A mountain or hill, typically conical, having a crater or vent through which lava, rock fragments, hot vapor and gas is being or have been erupted from the earth's crust.

produced when two blocks of the earth suddenly slip past one other

instrument used to detect seismic waves

travels quickly through the Earth and through liquid

“harbor wave”, a series of ocean waves with very long wavelengths caused by large-scale disturbances of the ocean

- a crack on the oceanic crust.

a group of volcanoes which is formed at the surface of the continental crust along the boundary where the plates converged.

a constant earthquake waves that are recorded but not felt

new materials from the mantle push the old ones.
