They will also get a better understanding of how plates move. Geology||Physical properties of Earth such as the interior structure of Earth, magnetic field, the flow of heat inside Earth, the force of gravity, movement of seismic waves|. These waves are only able to move through solids. How is the interior of Earth classified? You can find these images in most science or geography books. ] Both countries spent billions of dollars trying to build the most nuclear weapons. The core is called the "nife" layer since it is composed of heavy materials like nickel (Ni) and iron (Fe).

You can use a number of different materials to build a model of the earth. Interior part of the earth worksheet. Ask students if the shell of the egg could also represent tectonic plates.

Interior Part Of The Earth Worksheet

Since both P waves and S waves travel through the mantle, this means that it must be a layer of solid material. Have you ever thought about digging a hole to China? Interior of the earth worksheet. P waves can travel through both liquid and solid material, but S waves can only travel through solids. Seismic waves are vibrations that travel underground and occur as a result of the sudden movement of materials within Earth. Outer core: 1400 miles. The samples are then analyzed and help geologists determine the conditions and material inside Earth. Answer: d) Both solid and liquid.

Ask students to name the layers of the Earth's interior by using the egg as a model. An important consequence of the difference in density is that if tectonic plates happen to bring ocean crust and continental crust into collision, the plate with ocean crust will be forced down into the mantle beneath the plate with continental crust. Interior of the earth ppt. As body waves travel through the Earth's internal layers, their speed changes, causing the wave to 'bend. The core accounts for almost half of Earth's radius, but it amounts to only 16. One of the easiest is modeling clay.

The Earth's core is approximately 1, 931 miles thick and is divided into two parts: - The solid inner core, which contains solid metals, nickel, and iron. This signifies the outer core is liquid. The inner core is solid because the pressure at that depth is so high that it keeps the core from melting. How about baking an earth cake? Drilling Into the Earth Worksheet. The inner core is found to be in a solid state, and the outer core is in a liquid state. The mantle, made of iron, magnesium, and calcium-rich silicates, formed between the crust and core. You can treat the mantle as a single section, or add more layers of clay to show the different sections of the mantle.

Structure Of The Interior Of The Earth

The lithosphere can't be classified neatly as either crust or mantle because it consists of both. Mantle||30 kilometers below Earth's surface||Earth's thickest layer composed mainly of iron, magnesium, and calcium-rich silicate minerals; dense, hot semi-solid; forms layer of partially melted rock called the asthenosphere 100 to 200 kilometers underground; tectonic plates sit on asthenosphere and slide during tectonic activity due to convection currents; outermost layer is cool and rigid.

Geochemistry||Chemistry of Earth; distribution of minerals, rocks, soil, life forms, water, and atmosphere; carbon, nitrogen, phosphorus, water cycles|. This designates the asthenosphere or partially molten areas of the mantle. Stack them in layers after you've baked them, putting icing between the layers to help them stick together and on the top to represent the crust.

The waves that travel underground as a result of seismic activity are called body waves. Draw an extended arrow from each line and space (of the circles) and label it according to the layers of the Earth (this is optional, depending on how much help you want to offer students…e. Watch the video below to understand the composition of each layer. If scientists only detect P waves in a certain layer of Earth's interior, they know the layer is liquid. Ask students if they are able to see how volcanic eruptions can occur when plates dive under the mantle and force rocks to the surface of the Earth. The field of geology can be broken down into several branches all studying specific features or areas of Earth. Build this layered ball of clay and cut it in half to see a cross-section of the layers at the end.

Yellow, orange, red, blue, and green modeling clay. For example, the inner core is 800 miles and the outer core in 1400 miles, so the two together make a 2200-mile circle. The inner core is a solid, dense ball made mostly of iron and nickel. Here, P waves bend and pick up speed, telling us that the inner core must be solid material because P waves travel faster through solid than liquid. Mafic rocks contain minerals with less silica, but more iron and magnesium. The really interesting part about this 'solid' layer is that even though it is rock, it 'flows' like a very thick liquid. One idea is that it is minerals are undergoing another transition in this region because of pressure and temperature conditions, similar to the transition between the upper and lower mantle. For this, we need to study body waves so that we can see what Earth's 'body' is like. Author's Note: In addition, teachers may want to include a teacher-made diagram for students to label.
