This blog offers an exceptional discovery analizis the layers of our planet from the Earth's crust to the depths of hot mantle into the secret core of the planet. Also offers a look at what man kind will probably never reach, the more alien and hostile to the rocks, lava, and minerals below the earth's crust. While the crust is approximately 20 to 30 km deep in most places, humans have never traveled further, even so, research continues to prove impossible.
We can say that the interior of the Earth has many aspects that makes it a unique theme.

Hopefully you people like this.

The Water Cycle

Ring Of Fire

The Ring of fire is just outstandng.
It has so many thngs and so many things happen of the inside of it.
The ring of Fire streches from New Zealand along the eastern edge of Asia, north across the Aleutian islands of Alaska, and South Along the coast of North and South America. The Ring of Fire very active, its composed over 75% of the world's active and dominant Volcanoes.
This Huge ring of Volcanic and Seismic earthquake activity was noticed and described before the Theory of  Plate Tectonics theory. We now Know that The Rng Of Fire is located on the borders of The Pacific Plate and other major tectonic plates. Plates are like Giant rafts on the Earths surface, which often slide next to,colide with, and are forced underneath other plates. Around the Rng of Fire, the Pacific Plate is colliding with and sliding underneath other plates.Ths process is known as subduction and the volcanically and Seismically active area nearby is known as a subduction zone. There are tremendous energy created around these plates and they easily melt rock, into magma which rises to the surface as lava and for Volcanoes. There are currently about 1500 active volcanoes around the world. About 10% of these are located in the United States of America. Somany things happen n the Ring Of Fire, what else could happen in this amazing place?

Why is the Earth so Special?

Earth is a very special planet.
First of all, There is LIFE. It has Liquid water,Plate tectonics,and an atmosphere that shelters us from the worst of the suns rays. But many scientists agree that the most special feature is "us". "So far we haven't found it anywhere else" says Alex Wolszczan, from the Pennsylvania State University, who discovered the first planets in beyond our Solar Systems. He agreed that life was Earths single most impressive characteristic. The Earth is Just right, it has a perfect balance of everything to keep us all alive and breathing.Air, water, plants, everything.
Earth is just, wonderful, and we should all keep it clean and help save this outstanding Planet.

Plate Tectonics.

Plate Tectonics is an extraordinary concept. Scientists have a theory that Millions of years ago, the whole planet earth was one giant piece of land called "Pangaea". Over Millions of years, magma has been pushing and pushing the continents apart, so now we are seven continents.They think the theory may be real because how is it possible that the animals on Africa, are found in South America? The Tectonic Plates are composed of two types of lithosphere which are, thicker continental and thin oceanic.Basically there are there types of plate boundaries. 
They are, Transform Boundaries(conservative)occur when the two plates slide. There are Divergent Boundaries, which happen when two plates slide apart from each other, and there is convergent boundaries, they happen when two plates slide towards each other commonly forming a subduction zone. There are so many amazing things about plate tectonics and scientists have a long way to go to find out more great things!!

Natural disasters

Natural disasters, Wow.
They are awesome but scary. There are so many different types of Natural Disasters. Disasters occur when" hazards meet vulnerability".

Disasters are caused by human activities that disrupt the normal environment.
Some types of Natural Disasters are :
-volcanic eruptions            -thunderstorms 
-forest fires
They are natural and we can't stop them, they may cause losses of lives, but its just what the earth wants.

Composition, melt structure and properties.

Silicate melts are composed mainly of silicon, oxygen, aluminium, alkalis (sodium, potassium, calcium), magnesium and iron. Silicon atoms are in tetrahedral coordination with oxygen, as in almost all silicate minerals, but in melts atomic order is preserved only over short distances. The physical behaviours of melts depend upon their atomic structures as well as upon temperature and pressure and composition.
Viscosity is a key melt property in understanding the behaviour of magmas. More silica-rich melts are typically more polymerized, with more linkage of silica tetrahedra, and so are more viscous. Dissolution of water drastically reduces melt viscosity. Higher-temperature melts are less viscous.

Although now covered by forest the mountains around Panguipulli Lake in Chile were once magma that crystallized deep in earth's crust, now these magmatic bodies form the Panguipulli Batholith.


Is a mixture of molten rock, volatiles and solids that is found beneath the surface of the Earth, and is expected to exist on other terrestrial planets. Besides molten rock, magma may also contain suspended crystals and dissolved gas and sometimes also gas bubbles. Magma often collects in magma chambers that may feed a volcano or turn into a pluton.

Lava flow on Hawaii. Lava is the extrusive equivalent of magma.

Structure of the Earth

The interior structure of the Earth, similar to the outer, is layered. These layers can be defined by either their chemical or their rheological properties. The Earth has an outer silicate solid crust, a mantle, a liquid outer core and a solid inner core. Scientific understanding of Earth's internal structure is based on observations of topography and bathymetry, observations of rock in outcrop, samples brought to the surface from greater depths by volcanic activity, analysis of the seismic waves that pass through the Earth, measurements of the gravity field of the Earth, and experiments with crystalline solids at pressures and temperatures characteristic of the Earth's deep interior.

The volcanoes

Volcanes are one of many external manifestations of the energy from the interior of bur planet .The large number of active volcanoes on the Earth release material wich originates in the interior, such as lava, volcanic bombs, ash,gases, and so on.
Volcanics cannot be found everywhere. When we study the structure of litosphere we will see how there are some zones with a much higher volcanic seismic risk than others.This leads us to think that in these areas something is happening wich does not happen in other more stable places

the planet eath

this is to the fact that certain zones of the eath's crust produce tensions and friction between rigid rocky areas. When the enerqy has accumulated over a period of time it is released suddently and and the result is an earthquake.

Land relief and the processes that shape it

Land relief is the roughness and deformation of the Earth's crust. The large geological structures, such as mountain ranges, are features of land relief as are much smaller formations like beaches and cliffs.
The differences in land relief in different regions are the result of numerous factors. The factors in the modelling of land relief are listed below
