  • What is the hottest place on Earth?

Count one wrong if you guessed Death Valley in California. Many days it is really so, but the September 13, 1922 were recorded in El Azizia (Libya) temperatures of 136 degrees Fahrenheit (57.8 degrees Celsius) - when the highest temperature ever measured in Death Valley was 134 º F (56.6 ° C), registered on July 10, 1913.

  • And what is the coldest place on Earth? By far the coldest temperature ever measured on Earth was -129 Fahrenheit (-89 º C) at Vostok, Antarctica, on July 21, 1983.

3. What makes thunder?

If you thought, "Lightning!" Then my hat. But I had a more "enlightened" in mind. The air around a lightning bolt is superheated to about five times the temperature of the Sun This sudden heating causes the air to expand faster than the speed of sound,which compresses the air and forms a shock wave we hear as of thunder.

4. How much space dust falls to Earth each year?

Estimates vary, but the USGS says at least 1,000 million grams, or roughly 1,000tons of material enters the atmosphere each year and makes the surface of the Earth.Some scientists claims microbes rain down from space, and that extraterrestrial organisms are responsible for flu epidemics. The latter has not been tested, and I'm not holding my breath. (Claudia)

  • the Sun’s surface is a hot mass of gas that is more or less continuous with its atmosphere. “The Sun is a star is: usually it’s mostly hydrogen gas that is being converted into helium,” . If you could travel from the Sun’s outermost regions toward its core, would become so thick that you couldn´t move. “But the temperature and pressure is so high, there’s no possibility of anybody standing on what one thinks of as a surface,” Still, the Sun does have a surface we can see, called the photosphere. Up close, it resembles water bubbling in a pot on the stove, except that while water boils at 100 degrees Celsius, the photosphere is more than 500 times hotter. From this roiling surface, streams of particles shoot upward occasionally and then loop back down, forming giant arcs that can be thousands of miles long and contain millions of tons of material.

if the earth stoped rotating then our whole environment would be gone. No magnetic field, and many other things that would make life as we know it impossible. But it would not affect the rest of the universe. PS: Assuming one sidereal rotation per year, one part of the planet would be hot all the time and the other cold, same with night and day. But this would not fit the requirement of stopped rotation.


Due to the rotation of the Earth and that our planet is much more flexible in what one might imagine , this balloons in the middle section , creating a kind of training in pumpkin . For centuries the flattening is was reduced, but now, suddenly, is growing , as a recent study has shown . The blame for this increase in the Equatorial circumference is blames the accelerated melting of terrestrial glaciers . ( isabel )

Our planet has more than 4.5 billion years , only slightly younger than the sun . Recent evidence shows that in reality , Earth formed much before what , thought , only 10 million years later that the Sun , our common star , which began to form 4,600 million years ago . ( isabel )

A black hole or black hole is a finite region of spacetime caused by large concentrations of mass in its interior , with huge increase in the density , which causes a gravitional field such that no material particle , not even the photons of light , can espace from this region. ( isabel )

The moon's mean density is 3.34 gm/cm3 (3.34 times an equal volume of water) whereas the Earth's is 5.5. What does this mean? In 1962, NASA scientist Dr. Gordon MacDonald stated, "If the astronomical data are reduced, it is found that the data require that the interior of the moon is more like a hollow than a homogeneous sphere." Nobel chemist Dr. Harold Urey suggested the moon's reduced density is because of large areas inside the moon where is "simply a cavity." MIT's Dr. Sean C. Solomon wrote, "the Lunar Orbiter experiments vastly improved our knowledge of the moon's gravitational field . . . indicating the frightening possibility that the moon might be hollow." In Carl Sagan's treatise, Intelligent Life in the Universe, the famous astronomer stated, "A natural satellite cannot be a hollow object."

On November 20, 1969, the Apollo 12 crew jettisoned the lunar module ascent stage causing it to crash onto the moon. The LM's impact (about 40 miles from the Apollo 12 landing site) created an artificial moonquake with startling characteristics-the moon reverberated like a bell for more than an hour. This phenomenon was repeated with Apollo 13 (intentionally commanding the third stage to impact the moon), with even more startling results. Seismic instruments recorded that the reverberations lasted for three hours and twenty minutes and traveled to a depth of twenty-five miles, leading to the conclusion that the moon has an unusually light-or even no-core

The Moon is the only natural satellite of the Earth and the fifth largest moon in the Solar System. It is the largest natural satellite in the solar system relative to the size of your planet, one fourth the diameter of the Earth and 1 / 81 of its mass, and is the second densest satellite after Io. It is in synchronous relationship with the Earth, always showing the same face to Earth. The visible hemisphere is marked with dark volcanic mare between the bright and prominent ancient mountains astrobleme.(Maria.N)


In a general sense , it can be said that a star is any astronomical object that shines with the light itself .Appropiately , in a more technical and precise way , arguably it's asphere of plasma , which maintains its shape thanks to a balance of forces referred to as hydrostatic equilibrium . Balance occurs essentially between the force of gravity , that pushes matter towards, the center of the star and the pressure that makes the plasma outward, which as it happens in a gas , tends to expand it .( Isabel )

The biological and geological future of the Earth can be extrapolated based upon the estimated effects of several long-term influences. These include the chemistry at the Earth's surface, the rate of cooling of the planet's interior, the gravitational interactions with other objects in the Solar System, and a steady increase in the Sun's luminosity. An uncertain factor in this extrapolation is the ongoing influence of technology introduced by humans, such as geoengineering, which could cause significant changes to the planet. The current biotic crisisis being caused by technology and the effects may last for up to five million years. In turn, technology may result in the extinction of humanity, leaving the planet to gradually return to an equilibrium state.(claudia)

The movements of the Earth: Rotation and Traslation

(Pablo .M)

The Sun was formed about 4.57 billion years ago when a hydrogen molecular cloud collapsed. Solar formation is dated in two ways: the Sun's current main sequence age, determined using computer models of stellar evolution and nucleocosmochronology, is thought to be about 4.57 billion years. This is in close accord with the radiometric date of the oldest Solar System material, at 4.567 billion years ago.
The Sun is about halfway through its main-sequence evolution, during which nuclear fusion reactions in its core fuse hydrogen into helium. Each second, more than four million metric tons of matter are converted into energy within the Sun's core, producing neutrinos and solar radiation. At this rate, the Sun has so far converted around 100 Earth-masses of matter into energy. The Sun will spend a total of approximately 10 billion years as a main sequence star.
The Sun does not have enough mass to explode as a supernova. Instead, in about 5 billion years, it will enter a red giant phase, its outer layers expanding as the hydrogen fuel in the core is consumed and the core contracts and heats up. Helium fusion will begin when the core temperature reaches around 100 million K and will produce carbon, entering the asymptotic giant branch phase.

Agapornis es un género de aves de la familia de los loros (Psittacidae). Se les conoce vulgarmente como inseparables. El nombre científico tiene su origen etimológico en el griego: lo toma de las palabras ágape (amor) y ornis (pájaro), y lo deben a sus fuertes vínculos de pareja: el macho y la hembra pasan mucho tiempo juntos y con frecuencia se arreglan las plumas uno al otro; su posición en pareja, cabeza contra cabeza, es característica.
Son miembros pequeños y de gran colorido de la familia de los loros. Las 9 especies son pequeñas, con un tamaño que va de los 13 a los 16 cm, según la especie; y con cola corta y cuerpo sólido.
Se alimentan de semillas, frutas y brotes y, lo que es inusual en los loros, construyen un nido, en lugar de poner sus huevos en un agujero descubierto. Viven hasta 15 años.
Están presentes en el África subsahariana, Tanzania, Kenia y Madagascar.

Una planta carnívora, también llamada planta insectívora, es una planta que obtiene parte o la mayoría de sus necesidades nutricionales (pero no de energía) mediante la captura y el consumo de animales y protozoos, normalmente insectos (además de otrosartrópodos). Estas plantas crecen generalmente en lugares donde el suelo es pobre, en especial en nitrógeno, como las tierras ácidas pantanosas y los farallones rocosos. Charles Darwin escribió el primer tratado conocido sobre estas plantas en 1875.1
Los investigadores piensan que el hábito carnívoro ha evolucionado en, al menos, 10 linajes separados que se encuentran representados por más de una docena de géneros en cinco familias. Éstas incluyen alrededor de 625 especies que atraen y atrapan a sus presas, producen enzimas o bacterias digestivas y absorben los nutrientes resultantes. Además, más de 300 especies de plantas protocarnívoras en varios géneros muestran algunas, aunque no todas, de estas características.

  1. Hace poco más de cinco décadas que los naturalistas comenzaron a emplear el concepto de "la extinción" y éste empezó a hacerse cada vez más popular para designar un fenómeno que la actividad humana estaba provocando en todo el planeta: la desaparición de especies de la flora y la fauna silvestres.
    La expansión constante del humano sobre la naturalez, origina la destruccion de la cadena alimenticia animal, desequilibrando el status quo de las especies, inclusive al humano, quien subsiste gracias a la madre naturaleza, al igual que todas las especies, con diferencia de que la nuestra, es la unica que daña al ambiente.

    La extincion de los animales y el peligro de extincion de los animales es un problema que tenemos que solucionar para lograr mantener las especies animales para futuras generaciones
    La vida silvestre es un claro ejemplo de la estrecha relación entre cada uno de los componentes de un ecosistema, ya que la eliminación de cualquier especie acaba provocando el desequilibrio de los ecosistemas y la destrucción de fuentes de investigación científica. Por eso es necesario cuidar y respetar nuestro planeta y a todos sus habitantes. A continuación presentamos un resumen de algunas de las especies animales en muy serio retroceso numérico
    En el mundo hay más de 500 especies que están en extinción.
    Algunas de las razones son: caza por deporte, caza comercial, destrucción de su hábitat, animales para zoológicos, etc.

    Cada vez que se extingue una especie se rompe un "eslabón" de una Gran Cadena. Imaginen lo que pasaría si se rompieran varios "eslabones"? Sabemos que todo volvería a reacomodarse porque así funciona la Naturaleza, pero cada vez con una Cadena más corta... Nosotros, los seres humanos, deberíamos tener una mayor conciencia de esto, ya que este desequilibrio también de alguna manera nos afecta.Por qué? Porque también nosotros formamos parte de esa Gran Cadena: LA NATURALEZA Alvaro Cid
