Planets in the solar system

Introduction:

       Let's run through the entire solar system and learn all about the planets in the solar system so you can learn more if you like. :) enjoy !! :)

   The first planet that we to travel is the Mercury as you travel outward from the sun, Mercury is the closest planet in the sun. it orbits the sun at an average distance of 58 million km. and as i remember from my stock knowledge Mercury is airless and so without any significant atmosphere to hold in the heat. Mercury also is the smallest planet in the solar system and measuring 4879 km across to its equator. 

   The second planet from the sun is Venus, Venus has the virtual twin of earth in terms of size and mass, Venus orbits at an average distance of 108 million km. and completes an orbit around the sun every 224 days. apart from the size, Venus is different from earth because if you could stand on the surface of Venus,  you would experience 92 times the pressure of earth's atmosphere and as i know several spacecraft visited Venus and a few landers have actually made it down.

   The third planet is our home the Earth. it orbits the sun at an average distance of 150 million km. Earth is the only planet in the solar system known to support life. the Earth has a solid core of iron surrounded by a liquid outer core that generates a magnetic field that also helps protect life on Earth from the radiation of space and base on my research thousands of spacecraft have been launched to study the planet to measure it's atmosphere,landmasses,water,vegetation,and human impact.

  and Earth has only a single moon"the Moon"

 The 4th planet from the sun is Mars. the second smallest planet in the solar system. it orbits the sun at an distance of 228 million km. I was thinking that Mars is a large planet but my elementary teacher said that Mars is a tiny world with about half the diameter of earth and just 1/10th the mass. if you could stand on the surface of Mars you'd experience about 1/3rd's earth's gravity that was i remember when my elementary teacher explain about Mars and the other solar system and base on my research Mars has two tiny asteroid-sized moon the Phobus and Deimos.  

 The Jupiter mighty Jupiter is the biggest planet in our solar system it's so large in fact, Jupiter has a 2.5 times times the mass of all the rest planet in the solar system combined. Jupiter orbits from the sun at an average distance of  779 million km. it's diameter is 142,984 km. across. you could fit 11 earth's side by side and still have a little room.and Jupiter is almost entirely made up of hydrogen and helium with trace amounts of other elements and as what i remember only Galileo spacecraft has ever gone into orbit around Jupiter and Jupiter has the most moon in the solar system it has 63 moons.

 The Saturn, Saturn the 6th planet from the sun and the 2ND largest planet in the solar system. it orbits the sun at an average distance of 1.4 billion km. Saturn measures 120,000 km. across only a little less than Jupiter. but Saturn has much less mass and do it has a low density and the most amazing feature of Saturn is its ring. these are made of  particles of ice ranging in size from a grains of sand to the size of a car. some scientist think the rings are only a few hundred million years old. and base of my research only Cassini has actually gone into orbit around the Saturn and has captured thousands of image of planet and it's moon, Saturn has a total of 60 moons discovered ( so far ).

 Next comes Uranus, the 7th planet from the sun. it orbits the sun at an average distance of 2.9 billion km. Uranus measures 51,000 km across and Uranus is the 3rd largest planet in the solar system. while all the planets are tilted on their axes, Uranus is tilted over almost on it's side. Uranus was the first planet to be discovered with a telescope. it was first recognize as a planet planet in 1781 by William Herschel. and only one spacecraft Voyager 2 has ever visited Uranus up close. it passed by the planet in 1986 and captured the first close images.and Uranus has 27 known moons.

 

 The Neptune, Neptune is the 8th planet and final planet in the solar system, orbiting at an average distance of 4.5 billion km from the sun. it's the 4th largest planet, measuring about 49,000 km across. it might not be as big as Jupiter but still 3.8 times larger than Earth. Neptune is the second planet discovered in modern times. it was discovered at the same time by both Urbain Le Verrier and john couch Adams. Neptune has known 13 moons.
  
  And those are the planet in the solar system unfortunately planet Pluto is not a planet any more.

                                          God Bless!!!! 

Importance of Earth's hydrosphere

Introduction:
     As far as we know , the earth we live on is the only planet that is able to support life. among other factors, earth is just the right distance from the sun to have temperatures that are suitable for life to exist. also, the earth's atmosphere has exactly the right type of gases in the right amounts for life to survive. Our planet also has water on its surface, which is something very unique. in fact,earth is often called the''BLUE PLANET'' because most of it is covered in water. this water is made up fresh water in rivers and lakes, the saltwater of the oceans and the estuaries,groundwater and water vapor. together,all these water bodies are called HYDROSPHERE.

 

INTERACTIONS OF THE EARTH'S HYDROSPHERE:
     It is important to realize that the hydrosphere interacts with other global system, including the atmosphere, lithosphere and biosphere.


    * ATMOSPHERE when is heated,it evaporates and forms water vapor.when water vapor cools again,it condenses to form liquid water which eventually returns to the surface by precipitation rain or snow.

    *LITHOSPHERE in the lithosphere( the ocean and continental crust at the earth's surface), water is an important weathering agent , which means that it helps to break rock down into fragments and then soil, these fragments may be transported by water to another place , where they are deposited. this is called''EROSION

    *BIOSPHERE in the biosphere, land plants absorb water through their roots and then transport this through their vascular system to stems and leaves. this water is needed in photosynthesis.

THE IMPORTANCE OF EARTH'S HYDROSPHERE
      it is so easy sometimes to take our hydrosphere for granted and we seldom take the time to really think about the role that is part of the planet plays in keeping us alive.these are the some importance of hydrosphere as what i understand about hydrosphere...

  WATER IS A PART OF LIVING CELLS that each cells are living organisms is made up almost 75% of water and this allow the cells to function normally. and most of the chemical reactions are occur in life,
  WATER PROVIDES A HABITAT. the hydrosphere provides an important place for many animals and plants to live.
  REGULATING CLIMATES one of water's unique characteristic is its high specific heat. this means that water takes a long time to to heat up and also a long time to cool down. this is important in helping to regulate temperatures on earth so that they stay within a range that is acceptable for life exist.
  HUMAN NEEDS humans use water in a number ways. drinking water is obviously very important, but water is also used domestically in washing and cleaning and in industry also. water can also be used to generate electricity through hydro power.

 these are just a few of the very important functions that water plays in our planet. many of the functions of water relate to its chemistry and to the way in which it is able to dissolve substance in it.. and the earth's hydrosphere is important to us.

differences of technology

              
                In our modern world today many things are been develop or grown like our technology. Technology can be use anywhere like in our home,school even in workplaces. The advantage of technology is it help us to organize our daily activities and in workplaces also technology is the best way because it can help us to do our work faster and easy to communicate other people like our friends,relatives especially our family that work in far places or country's technology is the simple way of communicating your family and it can help us to understand other culture and society better so that we can be updated what happen to our community even in other country's especially in our surroundings and technology makes our life simple. 

                      
               On the other hand the disadvantage of technology is it can also be damaging to us depending on the circumstances and also technology can be manipulated by many irresponsible person we'll be to dependant on it,when technology fails were helpless in ( one way or another ) like when we are doing assignments and research papers ..and sometimes it can affect our health and lifestyle because of so much chemical  are hazardous and some of it can destroy our simple life and healthy life ( i miss the traditional living ) because in our world in the past no one manipulate your technology of the irresponsible person... most and worst of all it invasions your privacy because of  many lazy person .. thats the dis advantages of technology ..though technology can make our life simple but sometimes it destroy our simple life those people who manipulating the technology in worst way... technology makes our life more complex and more people are starving in total numbers , in this most technologically advanced age, even the kids are already know how to use technology such as computers ..and some of the child are have already sickness like the obesity of a kid and loss of personalities.
