The science that studies rocks, minerals and how mountain are formed, why earthquakes occur, and everything concerning the geosphere.
Parts of the Earth that are moving constantly
The tectonic plates...
are parts of the Earth
are constantly moving very slowly
the motion make changes in the continente position
travel with a great velocity
According to the Tectonic Plate Theory...
Earth's crust is floating on magma
The continents were joined together, and they they separated
Earth's crust is cover by rocks.
The continents were separated, and they the joined together.
____ are when the tectonics plates are separated.
When the tectonic plates are converge (join or together) is called ____
A tectonic accident happens when plates clash or come apart
Tectonic plates come apart and "scars" are formed on ocean floors.
When plates collide and creates deep trenches and mountains
The geological faults can't cause earthquakes.
Are cracks or fissures that originate in one plate, and are a product of movement in the lithosphere.
Mountains are the results of _____.
Also, are formed at the _____.
movement of the
convergent borders of tectonic plates.
divergente borders of tectonic plats
earthquake in the ocean
Mountains are the result of movements of the lithosphere; also, are formed at the convergent borders of tectonic plates, when one plate collides with another.
openings in Earth's crust when magma comes to the surface.
Are the most explosive landforms
eject molten rocks and clouds of thick ash into the atmosphere.
the result of movement of the lithosphere
Are formed at the convergent of tectonic plates
The expulsion of magma from inside is known as an ____
Lava is when____
magma reaches the Earth's surface
occur the expulsion of magma
the tectonic plates collide
the plates release tension
The movement of Earth's crust usually produced by shifting tectonic plates
What are the cause of an Earthquake?
The release of tension when plates moves.
The openings in Earth's crust
When a waves travels at great velocity
When the energy travels in the form of seismic waves, which shake the surface is known as ____
The point where the tension is happening is _____ ,
and the ____ is directly above the earthquake
Is an instrument used to calculated the intensity of an Earthquake and the location of its epicenter.
Is a succession of the values used to determine an earthquake's strength.
The higher the phenomenon's energy and force, the higher the number represented on the Richter scale.
How do tsunamis happen?
When an earthquake occurs at the bottom of the ocean, and it produce a giant sea wave.
Because of the motion of tectonic plates.
When eject molten rock and ash.
When tectonic plates come apart and 'scars' are formed on ocean floors.
Is a giant sea wave produced by earthquakes or underwater volcanic eruptions.
Giant sea wave
waves travel at great velocity
waves travel very slowly
when waves reach coast, it flood over the land
The release of tension cause an eruption
What should we do in the event of an earthquake?
Be prepared before, during and after the event
prepare backpack with first-aid kit and supplies; and make a family plan
stay calm and protect ourselves in a secure area.
stay away of dangerous areas.
meet our family
