Composition: iron and nickel. What are the layers of the Earth? Storyboard That accepts purchase orders. 6. Although made up of pretty different stuff, the top layers of the upper mantle and the crust tend to stick together. The movement of this thick layer of molten metal is thought to be a major factor in creating the Earth’s magnetic field. All the functions are correct with no grammar or spelling mistakes. German scientist Alfred Wegener developed the theory of continental drift to explain how mountains were formed. Deeply Boring: What’s the deepest hole on Earth? These are its main layers, starting with the outermost: crust – relatively thin and rocky. The mantle begins where the crust stops, at a point known as the Moho disconuity, named after our old pal Andrija Mohorovičić. Over the next century, scientists have continued to use basically this same technique, of measuring earthquake waves passing through the Earth, to build up a pretty good model of the inside structure of the planet. 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. Most of the functions are correct with some grammar and spelling mistakes. Trevor Nace Layers Of Earth 1. Describe the different sections of the Earth. mantle – has the properties of a solid, but can flow very slowly. 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. In this activity, students will label a model of the Earth. The crust is a solid layer of rock on the surface of the planet. They discovered that it is made up of these distinct layers: the crust, the mantle, and the core. © 2020 - Clever Prototypes, LLC - All rights reserved. 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. Change ), You are commenting using your Google account. Search for "earth" or "globe" and pull down the Earth item. However, that’s not the impression I’d get from pictures like this (from the BBC). How Many Layers Does the Earth Have. Outer Core. ( Log Out / More on that later. Earth comprises four separate layers. All storyboards are private and secure to the portal using enterprise-class file security hosted by Microsoft Azure. State: Solid. Let’s start from the outside and move our way in. Temperature: 5,000°C – 6,000°C. Certainly no-one has dug a hole right through the Earth to find out. Well, to cut to the chase, the average distance from the centre of the planet to the surface is 6371km. The Earth's structure and plate tectonics. But what about its depth, or to put it more correctly, it’s radius? In this activity, students will label a model of the Earth.Students should include a description of each part in addition to the label and arrow. Still images and related media. The layers of Earth diagram. 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. As we travel down through the mantle, it really begins to heat up too. That’s good news for us! Still images and related media. Click on "Image Options" to change to the diagram. It is made of iron and nickel and has temperatures reaching 5,500°C. This is one of the reasons that we see some similar animal and plant species on different continents today – because they used to be connected. Cross-section showing structure of the Earth, – has the properties of a solid, but can flow very slowly, is the rigid outer layer that is made up of the. Label the parts of the Earth using Textables and arrows. Teachers may opt to lower the security if they want to allow sharing. 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. All storyboards and images are private and secure. 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 The Earth is made up of different layers: The inner core is in the centre and is the hottest part of the Earth. The inner core is the solid part at the center of the Earth. ACTIVITY Assess and apply your learning STATIC Side-by-side comparison of composition vs. mechanical properties • Whole Earth • Near surface. Students should include a description of each part in addition to the label and arrow. The lithosphere is made up of a mixture of minerals. After taking measurements of a large earthquake that hit Croatia in 1909, Mohorovičić noticed that some of the underground shock waves had arrived at measuring stations sooner than expected based on their speed at surface-level. Earth's crust is what we walk on every day. The crust and upper part of the mantle are broken into tectonic plates. So I made this image to scale. Extending down to about 5155km, the outer core is quite a different beast from the mantle. Earlier on I mentioned that you can also divide the Earth into slightly different layers than shown to the right, based on how rigid or pliable different parts are, and how much they move about (as opposed to what they are made out of). The thickness varies between 3 and 30 miles. The outer core is the liquid part of the core which has a similar composition to the inner core. In addition, any storyboard can be made “sharable”, where a private link to the storyboard can be shared externally. 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! Compared to the total depth of the Earth, you can see that Mount Everest is a mere pimple, and the deepest trench in the ocean isn’t much more than a scratch! Weakly supervised clification of kioti tractor wiring diagrams lesson summary s draw and label semi supervised multi layered plate tectonics Label And Describe The Earth DiagramNew6a LayersfoldableEmily G Layers Of The EarthEarth S Interior StructureEarth S Interior StructureEarthquakes Volcanoes Geo416 Layer Pyramid Diagram Png Transpa Clipart ImagesLayers Of The Earth Animated … This gives us the crust, the mantle and the core, with various subdivisions. The internal structure of Earth is layered in spherical shells: an outer silicate solid crust, a highly viscous asthenosphere and mantle, a liquid outer core that is much less viscous than the mantle, and a solid inner core. Because of this we have what are known as tectonic plates – basically big chunks of lithosphere – ‘floating’ on the rest of the upper mantle. The parts of the mantle below 200km on the other hand are less rigid, and are at such high temperatures and pressures that they end up acting kind of like a very slow moving liquid (although they are mostly not made of molten magma, as is often assumed!). The crust of land masses tends to be a lot thicker, ranging from 10km thick to 70km or more in mountainous regions, but are made of a wider variety of lighter rock types. ACTIVITY Assess and apply your learning STATIC Side-by-side comparison of composition vs. mechanical properties • Whole Earth • Near surface. The author can choose to leave the storyboard public or mark it as Unlisted. Change ), Enter your email to get fresh posts direct to your inbox a few times a month (with a no spam promise). Crust. ( Log Out / Change ), You are commenting using your Facebook account. In this post you should see the big picture – literally. First, write the name of the layer of the Earth that each line is pointing to for letters A-E. Then write the thickness of the layers in blanks 1-4. (You can also create your own on Quick Rubric.). Some of the functions are correct with many grammar and spelling mistakes. just below it. The structure of the Earth comprises of the crust, mantle, outer core and inner core. In fact, the crust represents less than 1% of the Earth’s volume. It’s because of plate tectonics that we have the continents that exist today, but it’s also because of plate tectonics that the continents were different in the past, and are constantly changing into something else at a rate too slow for most of us to notice. Sign in, choose your GCSE subjects and see content that's tailored for you. The Earth’s … 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. Read about our approach to external linking. In the same way that light is bent or reflected when it hits something denser than air – like the lens in your glasses, or the water in a swimming pool – seismic waves were being bent or reflected by different densities of materials within the planet. https://www.storyboardthat.com/lesson-plans/structure-of-the-earth/label-diagram, This Storyboard That activity is part of the lesson plans for. Crust. It has been estimated that if poured onto the surface of the Earth, these precious metals would form a layer 45cm deep around the whole globe!

Let’s start from the outside and move our way in. 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. ( Log Out / These Crosscutting Concepts include. *(This will start a 2-Week Free Trial - No Credit Card Needed). Work is well written and carefully thought out. The crust is the uppermost and thinnest layer of the Earth made up of mainly sial (silica and … Animated diagram of the layers of the earth for teachers and students. The crust and top of the upper mantle make a relatively rigid layer, known as the ‘lithosphere’ (basically Greek for ‘rocky bit’), which has a maximum thickness of about 200km. Each version of Storyboard That has a different privacy and security model that is tailored for the expected usage. In recent blogs I’ve looked at the mass of the Earth and the circumference of the Earth. To stretch your more advanced students, have them compare the structure of Earth to the structure of another planet in our solar system, like Jupiter. Change ), You are commenting using your Twitter account. It’s a big number, but what does it mean? The lithosphere is made up of a mixture of minerals. The Earth is made of four layers. Back at the start of the 20th century, scientists discovered that measuring earthquakes could provide a window into the inner Earth. This different way of looking at things only really applies to the top layers, but it gives us a pretty important look at how the world we see at surface-level is created.
