Pollution

Here you go to see about and land pollution and water pollution.

• Land pollution:Is the degradation of Earth's land crust often caused by the human activities and their misuse of land resources example: the trash etc.
• Water polltion: Is the contamination of water bodies ( examples: rivers, lakes, ocean and groundwater. )

Now I go to explain this project ( in the pictures you go to see different pictures because in my neighborhood in not to much pollution one a little and the other one close of here. ) :

1. The first is here in my neighborhood one part is in the other side of the neighborhood here you see the different things that they leave a lot of construction materials when they goin to make here the houses they leave that like nothing. So now thw grass dont grow and no plants and they are like nothing.



2. The other one is in the back entrance of Brisas del Golf here you can see that the people take this place like a trash and in this place are animals like cows and those one and with this also the water can be contaminated the animals can die or transmit diseases.

In my neighborhood is agroup of kids that last year we go to the houses of our neighboors and said about what iis happening so we need help of others..... PLEASE! so we need to take care of our neighborhood and OUR planet.

Our dream neighborhood and world.

Solar System

Introduction: In this album you will see about the Solar system, the Sun is the is the Solar system star but it don’t is the biggest one in other galaxies they are massive star. Its large mass produces temperatures and densities in its core great enough to sustain nuclear fusion.

Mercury: Is the closet one in the Solar system and the smallest one, Mercury don’t have natural satellites and its and its only known geological features besides impact craters are lobed ridges or rupes, probably produced by a period of contractions early in its history. Mercury’s almost negligible atoms blasted off its surface by the Solar wind.

Venus: Is the close in size to Earth and like Earth has a thick silicate mantle around an iron and a core a substational atmosphere and evidence of internal geological activity. However, it is much drier than Earth and its atmosphere is ninety times as dense. Venus, most likely due to the greenhouse in the atmosphere. Not definitive geological activity has been detected on Venus.

Earth: Is the only one planet in the Solar system that have life until now. The largest body of water is hydrosphere, and its also the only one planet where plate tectonics has been observed. Earth atmosphere is radically differet for those of the other planets having been altered by the presence of life contain 21% free oxygen. The Earth have one natural satellite the Moon.


Mars: Is smaller than Earth and Venus. It possesses an atmosphere of mostly carbon dioxide ( CO2 ). Its red color comes from iron oxide in its soil. Mars has two natural satellites (Deimos and Phobos) captured asteroids. Its, surface peppered with vast volcanoes such as Olympus and Mons and rift valleys such as Valles Marineris.


Jupiter: Has known 63 satellites. Is the biggest one in the Solar system. Its composed by hydrogen and helium. Jupiters ‘s strong internal heat creates a number of semi permanent features in its atmosphere. The four largest Ganymede, Callisto, Io, and Europe, show similarities to the terrestrial planets, such as volcanism and internal heating.


Saturn: Distinguished by its extensive ring system, have several similarities of Jupiter such as its atmospheric composition and mangnetosphere. Saturn have 62 confirmed satellietes ; Show of which Titan, and Enceladus, show sings of geological activity, though they are largely made of ice. Titan is the second lightness moon in the Solar System , Is larger than Mercury and the only satellite in the Solar System with a substational atmosphere.


Uranus: At 14 Earth masses, is the lightest of the outer planets. Uniquely among of planets, its orbit the Sun on its side; its axial tilt is over ninety degrees to the ecliptic. It has much colder core than the others gas giants, and raditives very little heat into space. Uranus has 27 known satellites the latgest one being Titania, Oberon, Umbriel, Ariel, and Miranda.

Neptune: Though slightly smaller than Uranus is more massive ( equivalent to 17 Earths) and therefore more dense. It radiates more internal heat, but not as much as Jupiter and Saturn. Neptune has known 13 satellites. The largest Triton is geologically active with liquid nitrogen, Triton is the only large satellite with a retrograde. Neptune is acompained in its orbit by a number of minor planets, termed Neptune Trojans, that are in resonance with it.

Conclusion: In my conclusion a think I know more about the Solar System the planets The Sun and more this one a great topic to investigate so we must learn about the planets that are around of our planet Earth.
