Only seismic waves are shown in the Earth's core because they are the primary means by which we study the internal structure of the Earth. Seismic waves, generated by earthquakes or artificial sources, travel through different layers of the Earth, allowing scientists to infer properties like density and state (solid or liquid) based on their speed and behavior. Other forms of energy, like electromagnetic waves, do not penetrate the Earth's interior effectively, making seismic data the most reliable source for understanding the core's composition and characteristics.
S waves cannot travel through the outer core because they can only travel through solids, and the outer core is liquid.
The two main categories of seismic waves are body waves and surface waves. Body waves can travel through the earth's inner layers, but surface waves can only move along the surface of the Earth.

Seismic waves are the earths crust vibrating. there are two types of waves P-waves and S-waves (Primary and Secondary) Primary waves travel faster than s waves and can travel through solid and liquid, S-waves can only travel through solids
The vibrations that move away from an earthquake's origin are known as seismic waves. There are two main types of seismic waves: primary (P) waves, which are compressional waves that travel fastest through the Earth's interior, and secondary (S) waves, which are shear waves that move more slowly and can only travel through solids. Both types of waves propagate outward from the earthquake's focus, causing the ground shaking associated with seismic events.
There is no seismic wave that can only pass through the Earth's mantle. However S-waves can not travel through earth's outer core because it is a liquid.
S waves cannot travel through the outer core because they can only travel through solids, and the outer core is liquid.
There are two types of waves ; P waves and S waves . P waves can travel through solids , liquids , and gases . S waves can only travel through solids . The mantle is pure solid rock ; the outer core is made of liquid-iron and nickel . In other words , only P waves can travel through both the mantle and the core . Hope this helps ! Give thanks to 7th grade Earth science ! :D
Scientists suspect that the outer core is liquid because of its interaction with seismic waves. Actually, only one segment of inner earth is theorized to be liquid. This segment is known as the outer core
When eartquakes erupt only certaing wavelengths can travel through both liquids and solids, so when the scientists measure to see at what point in the earth the waves refract they can then tell what parts are solid and what parts are liquid
Primary seismic waves are longitudinal waves. Longitudinal waves can travel through solids, liquids and gasses (although seismic waves are of to low a frequency to normally be heard). Secondary seismic waves are transverse waves and only travel through solids.
Seismic wave measurements, particularly the behavior of P-waves and S-waves as they travel through the Earth, provide insights into the outer core's size. P-waves can pass through both solids and liquids, while S-waves only travel through solids. The absence of S-waves in certain areas indicates that those regions are liquid, allowing scientists to infer the outer core's boundaries. By analyzing the travel times and paths of these waves, researchers can estimate the depth and size of the outer core.
The inner core, outer core, and the mantle.
P waves (primary waves) are compressional seismic waves that can travel through both solids and liquids, while S waves (secondary waves) are shear waves that can only move through solids. When an earthquake occurs, P waves arrive at seismic stations before S waves, allowing scientists to analyze their travel times. The absence of S waves in certain areas indicates that the material in those regions is liquid, leading to the conclusion that the outer core of the Earth is liquid, while the presence of both P and S waves in the inner core suggests it is solid. This distinction helps geologists understand the physical state of Earth's core.
The wave shown is a shear wave, also known as an S-wave. This is the only wave type that can travel through the Earth's core because it does not propagate through liquids, like the outer core, where P-waves cannot travel.
P-waves, or primary waves, are seismic waves that can travel through all parts of the Earth, including solids, liquids, and gases. They are compressional waves that cause particles in the material they pass through to move back and forth in the same direction as the wave. This ability to travel through both the Earth's solid inner core and the liquid outer core distinguishes P-waves from S-waves, which only move through solids.
When there is an earthquake, seismic waves are created. Seismic waves are energy traveling through air, water, or rock. There are a few different types of seismic waves but the one in question here are called body seismic waves. These body waves can only travel through solids or rock. So we can measure a body wave created from an earthquake or atomic bomb on one part of the planet and measure it on a different part of the planet. So if Earth is solid to the core we should be able to measure the same seismic body wave on opposite sides of the planet, but we can't, the wave generated on one side of the planet isn't transmitted to the exact opposite side. This is because of the liquid layer of the earth. Once the body wave hits the liquid layer it is quickly dissipated.
