Respuestas a la pregunta
Earth was formed approximately 4.55 billion years ago, and life emerged a few billion years later. It is home to millions of species, including humans, and is currently the only astronomical body where the existence of life is known. The atmosphere and other abiotic conditions have been significantly altered by the planet's biosphere, favoring the proliferation of aerobic organisms, as well as the formation of an ozone layer that together with the terrestrial magnetic field block harmful solar radiation, thus allowing life on Earth.
Mars is a rocky planet made up of minerals that contain silicon, oxygen, metals and other elements that normally make up rocks. The surface of Mars is mainly composed of toleitic basalt with a high content of iron oxides that provide the characteristic red color of its surface. By its nature it resembles limonite, highly hydrated iron oxide.
