Layers of the earth sort
Sort the descriptions into the proper groups (LAYERS OF EARTH) based on your notes from yesterday. AKS 2f. I can identify and describe the layers of Earth. Crust COMPOSED OF SILICON, ALUMINUM, IRON, CALCIUM, SODIUM, POTASSIUM, MAGNESIUM COLDEST LAYER COMPOSED OF MOSTLY SOLID ROCK OCEANIC AND CONTINENTAL OUTERMOST LAYER LEAST DENSE THINNEST LAYER IN KILOMETERS MAJORITY OF THE LITHOSPHERE Mantle MELTED ROCK ASTHENOSPHERE COMPOSED OF SILICON, MAGNESIUM, AND IRON CONVECTION CURRENTS HAPPEN HERE CAUSES THE LITHOSPHERE TO MOVE THICKEST LAYER IN KILOMETERS THE UPPER PORTION IS A PART OF THE LITHOSPHERE Outer Core LIQUID LAYER LIQUID IRON AND NICKEL LIES BETWEEN THE MANTLE AND THE INNER CORE SECOND THICKEST LAYER SURROUNDS THE INNER CORE Inner Core SOLID IRON AND NICKEL MOST DENSE LAYER HOTTEST LAYER INNERMOST LAYER UNDER A LOT OF PRESSURE THE HOTTEST SOLID LAYER Earth's LayersThe crust is the thin outer layer of the Earth where we live. Well, it looks thin in most pictures and it is the thinnest relative to the other layers, but don't worry, we're not going to fall through by accident anytime soon. The next layer of the Earth is called the mantle. The mantle is the thickest layer at almost 3000km deep and contains melted rock called magma. The tectonic plates are a combination of the crust and the upper mantle, also called the lithosphere. These plates move very slowly on top of the asthenosphere , they only move a couple of inches each year. The reason the asthenosphere moves is due to the convection currents that occur there. The Earth's outer core is made up of liquid iron and nickel and is very hot. The outer core is very important to earth as it creates something called a magnetic field. Lastly, the Earth's inner core is the deepest and most dense layer made up of iron and nickel, just like the outer core, however, the inner core is different. The inner core is so deep within the earth that it's under immense(a lot) pressure and thus is made up of solid iron and nickel. Label each layer. CRUST MANTLE OUTER CORE INNER CORE
