The earth has a layered structure. From the outermost end of the atmosphere to the centre of the earth, the material that exists is not uniform.<\/p>\n\n\n\n
This is because it has a layered structure. The materials found in these layers are not uniform in their composition and density.<\/p>\n\n\n\n
From the surface to deeper depths, the earth’s interior has different zones and each of these contains materials with different characteristics.<\/p>\n\n\n\n
The Sun and its family of planets formed when a cloud of dust and gas condensed 4.6 billion years ago. Several hundred million years after the Earth took form, an outer crust developed.<\/p>\n\n\n\n
But these surface rocks are no longer available for study: they have disappeared into the interior of our dynamic planet.<\/p>\n\n\n\n
Our only clues to how the Earth formed come from meteorites and the Moon because both formed simultaneously with the planets.<\/p>\n","protected":false},"excerpt":{"rendered":"
