Be sure to follow the numbers so you don't lose your way during our expedition. Now, turn your helmet lights on and let's start digging!]]> 2017-03-20 14:05:14 UTC https://padlet.com/callie_kanupp/74xsts7edp25/wish/161180315 callie_kanupp https://padlet.com/callie_kanupp/74xsts7edp25/wish/161212468 So, you're probably asking yourself "Why do I care what the Earth's interior is like?". Well, the answer might just surprise you. Did you know that Earth is the only planet we know of that can sustain life? That means that our planet is unlike any other because it provides everything that our plants, animals, and even ourselves need in order to survive. Even planets, like Mars, that are very similar to ours in size and structure are unable to sustain life. You might be asking yourself "What makes our planet so special then?", and the answer to that question lies in our planet's interior.

The crust is Earth's outermost layer and the layer where we live.

The Earth's crust is the thinnest of its four layers, and only makes up about 1% of Earth's volume. Think about it like the shell on a hard boiled egg, only the crust is a solid layer made up of rocks and minerals.

The part of Earth's crust that sits beneath its continents is known as the continental crust. The continental crust is a layer of rock that can be up to 43 miles thick in some places. The rocks and minerals that make up the continental crust consist of mostly silicon and oxygen. These are some of the least dense materials that we find in the structure of our planet.

The part of Earth's crust that sits beneath the ocean is known as the oceanic crust. The oceanic crust is different from the continental crust in many ways. For example, the oceanic crust is much thinner, only ranging from about 3 to 5 miles thick. The oceanic crust is also a much darker color than the continental crust, and denser as well. While we can still find silicon and oxygen in the oceanic crust, we also find much heavier materials like iron and magnesium.

Even though, we call the crust Earth's outermost layer it is not one big connected piece of land. Instead, the crust is broken into different pieces called plates. These plates float on the Earth's mantle and move very slowly. Their movements are the cause of natural disasters such as earthquakes, volcanic eruptions, and tsunamis.

The mantle is a very thick layer measuring about 1, 800 miles across. 

The mantel is made of molten, or melted, materials like iron and minerals. It is believed that the uppermost part of the mantle is a rigid solid. While, beneath that solid layer we believe there is another unique layer of the mantel.

This unique lower portion of the mantle is believed to still be solid, but due to great amounts of heat and pressure this solid flows like a liquid. This ability of a solid to flow like a liquid is called plasticity

Due to intense heat from the Earth's core, the layer of the mantle that is closest to the center of the planet is much hotter than the portion that is closest to the crust. This difference in temperature causes convection currents to form as the hot magma rises and the cooler magma sinks. These convection currents are responsible for the slow steady movements of the crustual plates.

Although we often refer to this part of our Earth as just the core it can really be divided into two distinctly different layers known as the inner core and the outer core.

The Earth's outer core is made up of iron and nickel and is very hot. The temperature of the outer core ranges from 4400 to 5000= degrees Celsius. This is so hot that the iron and nickel metals are in the liquid state. The outer core is very important to earth as it creates something called a magnetic field. The magnetic field the outer core creates goes way out into space and makes a protective barrier around the earth that shields us from the sun's damaging solar wind.

 The Earth's inner core is 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 pressure. So much pressure that, even though it is so hot, it is solid. The inner core is the hottest part of the Earth, and, at over 5000 degrees C, is about as hot as the surface of the sun.

It includes the crust and part of the upper mantle that contains rigid rocks. Beneath this layer is the asthenosphere where the rocks in this part of the upper mantle are not rigid. The rocks can flow like a liquid or break apart similar to silly putty. 

 The asthenosphere is the layer of the Earth that lies below the lithosphere. It is a layer of solid rock that has so much pressure and heat the rocks can flow like a liquid. The rocks are less dense than the rocks in the lithosphere. This allows the tectonic plates in the lithosphere to move around on the Earth's surface by "floating" on the rocks that are slowly flowing like a liquid.

However, they are still very different. Visit the websites below to learn more about each planet. Compare and contrast the two planets using a venn diagram, then write a paragraph explaining why you think Earth has the ability to sustain life while Mars does not.
