The reason it is these elements is because when the Earth was first forming these heavier elements sank the the middle while the lighter ones floated to the surface. The inner core is ten percent of the earths radius. The outer core is also iron and nickel but it is molten and liquid. The core is about 5,500 degrees Celsius and the pressure is immensely strong down inside the core. outside the core is the mantle which is about 2,900 kilometers thick. on top of the mantle is the crust which is the smallest layer of the earth which is solid rock. there are two times of crust oceanic and continental crust. the movement of the crust depends on the movement of the mantle which is dependent on heat. The crust is plates not on solid surface.

The line between the Earth and the atmosphere and space is about 100 kilometers up. This line is called the Karman line if you get above it, you are in space. The atmosphere is roughly 78% nitrogen, 21% oxygen, 1% argon, and an assortment of trace gases. We have a 25 kilometer thick on average of ozone, a molecule of oxygen great at absorbing radioactive sunlight rays. The light hitting the ozone layer doesn't just absorb them it channels these particles. these particles smash into air molecules causing an Aurora Borealis.   Carbon dioxide rests in the atmosphere and heats the earth the more of Co2 that enters the air.]]> 2017-10-05 16:19:28 UTC https://padlet.com/jsotti08/cfruxaia6t6e/wish/194378628 jsotti08 https://padlet.com/jsotti08/cfruxaia6t6e/wish/194378629 (Tip - pause screen when graphic comes up and type below) Our atmosphere consists of 78% nitrogen, 21% oxygen, and 1% argon with an assortment of transverse gases.]]> 2017-10-05 16:19:28 UTC https://padlet.com/jsotti08/cfruxaia6t6e/wish/194378629 jsotti08 https://padlet.com/jsotti08/cfruxaia6t6e/wish/194378630  There is water vapor too which is about 8-15 kilometers this part of the atmosphere is the hottest part of the atmosphere at the bottom. This consists of bundles of water vapor, or clouds. These clouds are what give us weather. The earth is covered with water which rests on oceanic plates this water is lower than continental plates which causes it to flow into it. ]]> 2017-10-05 16:19:28 UTC https://padlet.com/jsotti08/cfruxaia6t6e/wish/194378630 jsotti08 https://padlet.com/jsotti08/cfruxaia6t6e/wish/194378631 70% of the earths surface is covered in water.]]> 2017-10-05 16:19:28 UTC https://padlet.com/jsotti08/cfruxaia6t6e/wish/194378631 jsotti08 https://padlet.com/jsotti08/cfruxaia6t6e/wish/194378632 The biosphere is all the habitats of the Earth including plants and animals. The earth is the only habitable planet in our solar system. However us as humans have created the industrial revolution in the past years increasing the carbon dioxide in the air which in turn makes Earth heat up and destroys the ozone which if we destroy it completely Earth will be unhabitable.]]> 2017-10-05 16:19:28 UTC https://padlet.com/jsotti08/cfruxaia6t6e/wish/194378632 jsotti08 https://padlet.com/jsotti08/cfruxaia6t6e/wish/194378633 We are adding more carbon dioxide into the air causing the Earth to heat up and melt the ice caps which causes water levels to rise.]]> 2017-10-05 16:19:28 UTC https://padlet.com/jsotti08/cfruxaia6t6e/wish/194378633
