These waves have different properties that provide indirect evidence in helping determine the composition of Earth's layers. One of the ways the United States was able to monitor nuclear testing by the Soviet Union was to study seismic waves that radiated underground from the nuclear tests. This means they retain their frequency as they arrive at the seismic station. You can use a number of different materials to build a model of the earth. In some places, the crust is thin, while in other places it is thicker. This signifies the outer core is liquid. The same thing happens to body waves when they travel through the earth. Geochemistry||Chemistry of Earth; distribution of minerals, rocks, soil, life forms, water, and atmosphere; carbon, nitrogen, phosphorus, water cycles|.
P waves are compressional or longitudinal waves able to move through any type of material (solid and liquid). Upper mantle: 225 miles. Ask students how they think scientists are able to predict what the inside of our Earth looks like.
Diagram Of The Interior Of The Earth
P waves are compressional or longitudinal waves. 5), which contains garnets. The core is extremely hot (~3500° to more than 6000°C). Only able to move through solids. The center of Earth is iron and nickel. Seismic waves are recorded by a machine called a seismograph, which tells us about the strength and speed of the seismic waves.
It is formed from the crust as well as the uppermost layer of the mantle which is stuck to the underside of the crust. The mantle is a little bit like a sandwich. 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. 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. The core is primarily composed of iron, with lesser amounts of nickel. Explanation: The upper portion of the mantle is known as the asthenosphere. Do not weaken as they travel. Demonstrate how to tap the egg lightly on all sides. There are two types of body waves, called P waves and S waves. It has a density higher than the crust portion with 10 to 200 km thickness. Ask students if the shell of the egg could also represent tectonic plates. Body waves are seismic waves that travel through Earth's interior, or its 'body. '
