It is outer rigid part of the earth

The outermost later of the lithospshere

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

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

Extends to about 2900 km from the Earth’s surface

what is the movement of lithospshere called

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

Which is not a Major Plate

Which is a Minor plate?

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

can travel through the earth

travels quickly through the Earth and through liquid

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

can only travel through the surface of the earth

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

causes the most damage to the structure during an earthquake

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

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

What does PHILVOCS stands for?

instrument used to detect seismic waves

a collected record of seismic waves

a constant earthquake waves that are recorded but not felt

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

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.

a series or chain of mountains that are close together

- a crack on the oceanic crust.

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

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

a hot molten material found at the mantle.

a column of rising magma.

a shaking of the ground.

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

a volcanic arc that is surrounded by water.

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

converging continental crusts or plates which could cause shallow Earthquakes

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

– takes place when two plates collide

formed when two plates move apart

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

caused by the force of separation of plates.

underwater mountain ranges.

new materials from the mantle push the old ones.
