What+are+the+Physical+Characteristics+or+Earth+(Neil)

Hi, I’m Sxtriks (Say six-tricks.) Today I’m going to show you the physical characteristics of Earth. Earth is the only planet in the Milky Way Solar System that has life. We have the five necessary things to hold life. One being water. Two being a breathable atmosphere. Three being our climate. Not too warm like a day on Venus and not too cold like a night on Mars! Four being light. Although other planets receive light, no planet uses it like Earth does. Plants on Earth use light in Photosynthesis. And last but not least, the sun! No life on Earth would survive if it weren’t for the sun. Earth might not have even been created if it wasn’t for the sun! The reason we can have life on Earth is because of our ideal location in relation to the sun. Not to far and not too close! But that’s only one of the physical characteristics of Earth. Earth also contains mountains. One very popular one is Mount Everest. But we’ve been talking about the crust. Earth has four layers. The top layer is the crust; under the crust is the mantle. Hiding under the mantle is the outer core. Then the hard rocker in the middle is the inner core, or just The Core. The inner Core and outer core are made out mostly of nickel and iron. The outer layer is made out ofsilicon, iron, magnesium, aluminum, oxygen and other minerals. The crust of the Earth is mostlyoxygen, silicon, aluminum, iron, calcium, sodium, potassium and magnesium. Although you wont see most of these materials on the crust because the Earth’s crust is mainly covered with water. The atmosphere of Earth is Nitrogen and oxygen, with smaller amounts of carbon dioxide, water vapor and other gases. These are the characteristics of earth and why it’s special.
