Finally color each layer of the Earth according to whether it is solid, liquid, or … Difficulty Level 2 (Reinforcing / Developing), (These instructions are completely customizable. The crust and upper part of the mantle are broken into tectonic plates. Home Economics: Food and Nutrition (CCEA). The top of the lower mantle sits at around 1000C, with the lower levels hitting as much as 4000C – close to the burning point of diamond! Due to this, the outermost layer is made of the lightest materials such as rocks and granites and the innermost layer consists of nickel and iron. The lithosphere is made up of a mixture of minerals. Fill in your details below or click an icon to log in: You are commenting using your WordPress.com account. This layer starts under the crust and extends down to a depth of about 670km. You can also divide the planet up into what are usually known as ‘mechanical’ layers, based on the how much they move around, or whether they are solid or more flexible. Animated diagram of the layers of the earth for teachers and students. So, much like the layers of the Earth, the implications of its inner workings go pretty deep! The mantle begins where the crust stops, at a point known as the Moho disconuity, named after our old pal Andrija Mohorovičić. Read about our approach to external linking. That’s good news for us! Certainly no-one has dug a hole right through the Earth to find out. The author can choose to leave the storyboard public or mark it as Unlisted. Along with nickel and iron, the core is thought to contain large amounts of precious metals (such as gold and platinum). In addition, any storyboard can be made “sharable”, where a private link to the storyboard can be shared externally. Animated diagram of the layers of the earth for teachers and students. The crust is a solid layer of rock on the surface of the planet. After clicking "Use This Assignment With My Students", update the instructions on the Edit Tab of the assignment.). All storyboards are private and secure to the portal using enterprise-class file security hosted by Microsoft Azure. It is made of iron and nickel and has temperatures reaching 5,500°C.
You can then work out the rough thickness and density of layers from the amount of bending or reflection. The Earth is made of four layers. Like the upper mantle, the lower mantle is still essentially solid, and actually moves around less than the upper layer, mostly because of the extreme pressure it is under. Work is well written and carefully thought out. The Earth is mostly made of rock and metal. Scientific understanding of the internal structure of Earth is based on observations of topography and bathymetry, observations of rock in outcrop, samples brought to the surface from greater depths by volcanoes or volcanic activity, analysis of the seismic waves that pass through Earth, measurements of the Sign in, choose your GCSE subjects and see content that's tailored for you. The movement of this thick layer of molten metal is thought to be a major factor in creating the Earth’s magnetic field. Storyboard That accepts purchase orders. | Size Matters! *(This will start a 2-Week Free Trial - No Credit Card Needed). (You can also create your own on Quick Rubric.). These plates then move around – at about the same speed as your fingernails grow – as new rock from deep within the Earth is pushed up by convection currents and pushes these chunks of lithosphere over the mantle below. https://www.storyboardthat.com/lesson-plans/structure-of-the-earth/label-diagram, This Storyboard That activity is part of the lesson plans for. Inner Core. Temperature: 4,300 K (4,030°C) in the outer regions to 6,000 K (5,730°C) closest to the … The layers of Earth diagram. This was happening because layers of material within the Earth are more or less dense than the other layers around them. Crust. These are its main layers, starting with the outermost: crust – relatively thin and rocky. The mantle is thought to be made up of a range of rock types and minerals that we don’t see that much at the surface, such as garnet, olivine and peridotite, varying with depth.
The upshot of this all is the process called plate tectonics – where the surface of the planet is split into massive rocky ‘plates’ the size of continents. Deeply Boring: What’s the deepest hole on Earth? ACTIVITY Assess and apply your learning STATIC Side-by-side comparison of composition vs. mechanical properties • Whole Earth • Near surface. Although also made up of nickel and iron, the inner core is under such incredible pressure that it remains a solid lump, roughly 70% the diameter of the moon. Unlisted storyboards can be shared via a link, but otherwise will remain hidden. ACTIVITY Assess and apply your learning STATIC Side-by-side comparison of composition vs. mechanical properties • Whole Earth • Near surface. The Earth is almost a sphere. ( Log Out / This gives us the crust, the mantle and the core, with various subdivisions. So I made this image to scale. Our team of exam survivors will get you started and keep you going. However, that’s not the impression I’d get from pictures like this (from the BBC). just below it. 6. The Earth is made up of different layers: The inner core is in the centre and is the hottest part of the Earth. When introducing the structure of the Earth, a diagram is essential to helping students visually understand each part. These are its main layers, starting with the outermost: The Earth’s lithosphere is the rigid outer layer that is made up of the crust and the part of the mantle just below it. The top layer, which is what we stand on is the crust, next comes the mantle and finally the core. Earth's Structure What's inside the earth? Well, to cut to the chase, the average distance from the centre of the planet to the surface is 6371km. Not only does the magnetic field make our compasses work, it also keeps us nicely shielded from the radiation blasted out by the sun and other sources in deep space, which would otherwise have stripped away our atmosphere by now. But what about its depth, or to put it more correctly, it’s radius? Because of this we have what are known as tectonic plates – basically big chunks of lithosphere – ‘floating’ on the rest of the upper mantle. What are the layers of the Earth? The Earth is made up of different layers: The inner core is in the centre and is the hottest part of the Earth. The lithosphere is made up of a mixture of minerals. The Earth is made of four layers. The mantle is a semi-liquid layer of magma, or molten rock, that moves due to convection currents. By breaking up the Earth by the stuff it’s made of, five fairly clear layers emerge: crust, upper mantle, lower mantle, outer core and inner core. Create a free website or blog at WordPress.com. Based on these measurements, he figured out that these underground shock waves – or seismic waves – were being caused to change speed and direction, or bounce back, when they hit different layers within the Earth. Most of the functions are correct with some grammar and spelling mistakes.
Describe the different sections of the Earth. The crust is the rocky shell of the planet, and its thickness varies pretty widely.
Work shows little evidence of any effort. Change ), Enter your email to get fresh posts direct to your inbox a few times a month (with a no spam promise). How Many Layers Does the Earth Have. Teachers can view all of their students’ storyboards, but students can only view their own. Earth comprises four separate layers. As the awesome Australian science-guru Dr Karl has said many times – the Earth’s crust is like a postage stamp stuck to a soccer ball. It feels pretty sturdy, but proportional to the size of the Earth it’s similar thickness (perhaps even thinner) to the shell on a hen’s egg!
