Mars grew out of gas and dust of a very different composition from the material that became the Earth, says a new study. By Newton

Answer 2

Mars was formed over 4.5 billion years ago through a process known as accretion, where dust and gas in the early solar system collided and clumped together to create a rocky planet. It eventually differentiated into layers, with a metallic core, rocky mantle, and crust. Today, Mars is a terrestrial planet with a thin atmosphere, cold temperatures, and diverse geological features.
