MARS                                                    
  Mars is the 4th planet from the sun and the second smallest 

  planet in the solar system. It is half the size of Earth.                                                        

  Mars is sometimes called the red planet because in the ground 

  there is rest of iron.                                                                              

                                                                                                              Mars is a cold desert. Some scientist believe that Mars could be

  covered with water, but now, Mars dont have any ocean.

  It is very dry.                                                                                                                    

                                                                              
  It has a very thin atmosphere made of carbon dioxide, nitrogen,

  and argon.                                                                                                                                                                                                       
 Mars is very similar to earth compared to other planets. 

 Mars has, like the earth ,seasons, ice caps, volcanoes, canyons ,

 and weather .

 Scientists dont know if there was life in Mars in the past and 

 they want to know if it could support life now or in the future.

  Its one of the bestplanets for studing because it is closer than 

 others.
