the earth

the earth thas not have its on lite nider do eny of the other planets.the reason why whi see and iluminated planet when we look at the earth from space is because the earth resest light from the sun whish is the nearest star.

the earth is the therth planet in the solar sistem, whish is a set of celestial bodies be longin to a galaxi could the milkiway. the earth has onli one satelite could the moon.

Earth's lithosphere In the Earth, the lithosphere includes the crust and the uppermost mantle, which constitute the hard and rigid outer layer of the planet. The lithosphere is underlain by the asthenosphere, the weaker, hotter, and deeper part of the upper mantle. The boundary between the lithosphere and the underlying asthenosphere is defined by a difference in response to stress: the lithosphere remains rigid for long periods of geologic time, where as the asthenosphere is plastic. The lithosphere is fragmented into plate tectonics (shown in the picture), which move independently relative to one another.
The concept of the lithosphere as Earth’s strong outer layer was developed by Barrell, who wrote a series of papers introducing the concept (Barrell 1914a-c). The concept was based on the presence of significant gravity anomalies over continental crust, from which he inferred that there must exist a strong upper layer (which he called the lithosphere) above a weaker layer which could flow (which he called the asthenosphere). These ideas were enlarged by Daly (1940), and have been broadly accepted by geologists and geophysicists. Although these ideas about lithosphere and asthenosphere were developed long before plate tectonic theory was articulated in the 1960s, the concepts that strong lithosphere exists and that this rests on weak asthenosphere are essential to that theory.
The lithosphere provides a conductive lid atop the convecting mantle; as such, it affects heat transport through the Earth.
The division of Earth's outer layers into lithosphere and asthenosphere should not be confused with the chemical subdivision of the outer Earth into mantle, and crust. All crust is in the lithosphere, but lithosphere generally contains more mantle than crust.
There are two types of lithosphere:
Oceanic lithosphere, which is associated with Oceanic crust
Continental lithosphere, which is associated with Continental crust



hyerosphere: Hydrosphere
From Wikipedia, the free encyclopedia


The movement of water around, over, and through the Earth is called the water cycle, a key process of the hydrosphere.
A hydrosphere (from Greek ύδωρ - hydor, "water" + σφαίρα - sphaira, "sphere") in physical geography describes the combined mass of water found on, under, and over the surface of a planet.

A thick hydrosphere is thought to exist around the Jovian moon Europa. The outer layer of this hydrosphere is almost entirely frozen, but current models predict that there is an ocean up to 100 km in depth underneath the ice. This ocean remains in a liquid form due to tidal flexing of the moon in its orbit around Jupiter.
It has been suggested that the Jovian moon Ganymede and the Saturnian moon Enceladus may also possess sub-surface oceans. However the ice covering is expected to be thicker on Jupiter's Ganymede than on Europa.



atmosphere: Atmosphere
From Wikipedia, the free encyclopedia
For other uses, see Atmosphere (disambiguation).


View of Jupiter's active atmosphere, including the Great Red Spot.
An atmosphere (from Greek ατμός - atmos, "vapor" + σφαίρα - sphaira, "sphere") is a layer of gases that may surround a material body of sufficient mass,[1] by the gravity of the body, and are retained for a longer duration if gravity is high and the atmosphere's temperature is low. Some planets consist mainly of various gases, but only their outer layer is their atmosphere (see gas giants).
The term stellar atmosphere describes the outer region of a star, and typically includes the portion starting from the opaque photosphere outwards. Relatively low-temperature stars may form compound molecules in their outer atmosphere. Earth's atmosphere, which contains oxygen used by most organisms for respiration and carbon dioxide used by plants, algae and cyanobacteria for photosynthesis, also protects living organisms from genetic damage by solar ultraviolet radiation. Its current composition is the product of billions of years of biochemical modification of the paleoatmosphere by living organisms.

the inside of the earth

when we stady the enside of the earth we find three layers:

the crust, the mantle, an the nucleus

the crust: is the external layer of the earth its thickness varies from six two twelfs km on the sea beds to around sixty km in the continental areas were the great mantle ranges are located.

the mantle: is the layer whish goes from the earth earth's crust down to a drpth of two, 2900 km.

the core: is the inner-most layer. it goust from a tip two 2900 km to the earth's core whish is located about 6.378 KM FROM THE SURFACE. 

the earth's crust and the mantle form the lithosfear.

stars

• diferent types of stars, stars have different characterics:
  color:when we luck at the stars though binocules or evenwith the naked eyes we can see different tound and different stars. Some are bluish, readdish, orange, and so on.
  - the sun is a yellow star.
  
  on the other hand,sirius be of comies majoris a hundred times smaller than the sun
  bear
  
  brightness
  some stars are brigther than others.sirius is very bright other sars are so faint that we cannot see them with the naked eye, they have been discoverd thanks to the use of telescopes
  light
  some stars emmit more light than others, to stars emitting the same amount of ligth will not be as brigth as each other is they are at different distances from the earth.

the galaxies

galaxi are make up of groups of stars, geses and dust awar galaxi is could the milki way, the nears galaxi to awer own is andromeda whish is more than two million lait years away. this means that when why look a this galaxi whi are seing it as it was more than two millions years ago.


dependy or there cheip galaxis can be:

elliptical: is more or less spherica

spiral: a flat thisc whith several arms caming aut of the nucleous of spiral irregural

irregular: whit not specific shape

what are the celestial bodies in the solar sistem

the solar sistem is made up of yhe sun and the celestial bodies that orbit araund the sun.

. the sun is a estar. it is yellow energy thet is generated and trasnitted from the sun is what sustains live on earth.

. there are nine planets whish orbit oround the sun. in the order of the celest to the sun to the farthest away from the sun they are. mercury, venus, the earth, mars, jupiter, saturn, uranus, neptune and pluto. some planets also have other bodies orbithing around them. there are also satellites. for example, the moon is the earth satellites. some planets have more than twenty satellites.

. there also other bodies orbiting around the sun such as comets and asteroids. we can see a long tain on the comets when day get close to the sun.

we can say then, that the solar sistem is made up of a estar (the sun), nine planets whit their satellites and other smaller bodies.(asteroids and comets)
