recall that for their study, the geosphere (Earth structure ranging from crust to core) were divided in three parts: crust, mantle and core. as you go down from the surface to the interior, the temperature rises about 1 º C per 33 m approx. (The rise in temperature with depth we call Earth GRADE GEOTHERMAL ).
The energy released inside our planet, ( GEOTHERMAL ) depends largely on the column systems disintegration of radioactive uranium, plutonium and thorium.
This geothermal energy is responsible for:
a) VOLCANOES b) Earthquakes (Earthquakes)
c) THE MOVEMENT OF LOCAL AUTHORITIES CONTINUE
d) formation of mountain ranges
e) LA SOME TRAINING IPO T S ROCK.
f) HYDROTHERMAL PHENOMENA as geysers, hot springs, etc..
In the right image you can see an artificial geyser caused in the Timanfaya, it is a claim for your ris mo as it surprises ndent e as in a pipe buried in the mountains it pours bucket of water and only 3 or 4 seconds, comes with great force a jet of steam produced by the internal heat of the mountain (demonstration "in situ" of the internal energy of the planet)
VULCA Anisman.
volcanism call the phenomenon that the output is outside the Earth's magma, accompanied by gas emissions.
A volcano is a geological formation consisting of a fissure in the earth's crust that builds up on a mound of volcanic material (volcanic cone) formed by the lava solidified materials solids being thrown from inside the Earth. The volcanic material flowing inside the volcano along the chimney to reach the outside of the crater. In the left image you can see explained above and below, a real video of a volcanic eruption.
YOUR TURN NOW:
All volcanoes are not equal, we classify the type of lava ejected (if it more or less dense), the type of materials to shed, the height of the volcanic cone, etc.
Make some notes in your notebook about:
a) The types of volcanoes
b) Classification of products that can give the volcanoes.
To do this you can consult the books you deem appropriate and / or websites. Here I put some links to pages where you can see, simply click on them:

EARTHQUAKES
We call earthquakes to shake the earth's surface due usually to rupture or displacement inner crust. Are also called seismic, earthquakes or earthquakes.
The exact location of the inner bark where the break occurs is called Hypocenter or SEISMIC FOCUS and from there spread the vibrations of waves in all directions ( seismic waves).
The surface point closest to the hypocenter is called EPICENTER and is where the earthquake was perceived first and with greater intensity. Epicenter of the earthquake is transmitted by the Earth's surface from surface waves called seismic waves.
MEASURE AN EARTHQUAKE FORCE
To measure the strength or the destructiveness of an earthquake, we used scales that measure the intensity and magnitude of an earthquake.
Intensity is a subjective assessment of the damage it has caused
the earthquake on the ground, animals and people and man-made structures. Are scales that measure the Mercalli intensity or MSK (these two are from the earthquake of intensity I to XII intensity). Magnitude is an objective measure that is carried out with a device called a seismograph and the universally used scale is the Richter scale and allows us to classify earthquakes:
1) Microterremotos not exceed grade 3
2) small earthquakes, ranging from 3 to 5
3) Earthquake moderate grade 5 to grade 7
4) Major earthquakes, exceeding the Grade 7
