# Types of Waves that Travel Through the Earth's Surface * P waves arrive first and vibrate energy back and forth * S waves arrive second and shake side to side and up and down * Surface waves arrive last when an earthquake has occurred, they last the longest, are the most violent from the surface
Seismic wave travel through the Earth during an earthquake.
They can be split into two main groups, surface waves and body waves.
Surface waves:
Body Waves:
The P-wave is a compression / longitudinal wave and so unlike the S-wave is able to travel through the liquid outer core.
P waves travel faster that S waves.
The 'P' in P waves stands for primary, and the 'S' in S waves stands for secondary.
surface wave
primary waves
They go faster through the inner core than the liquid outer core.
S waves cannot travel through the outer core because they can only travel through solids, and the outer core is liquid.
The molten iron and medals inside the earths core are the reasons for the earths magnetic core.
no it is not true. there is solid iron and nickel in the Earths core
The earths magnetic field results from deep in the earths core. Magnetic conduction from within the earths core is believed to be the cause of this.
They go faster through the inner core than the liquid outer core
the outer core is liquid; the inner core is solid
They go faster through the inner core than the liquid outer core.
Yes, P-waves (primary waves) can travel through the Earth's mantle. P-waves are a type of seismic wave that is capable of propagating through solid, liquid, and gaseous materials. They are the fastest seismic waves and can travel through the mantle, which is the layer between the Earth's crust and core.
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.
Seismic waves that can pass through the centre of the Earth must be capable of travelling through liquids (as the outer core is molten). As such we know that these waves are longitudinal or compression waves.
there are convection currents in the upper core.
Scientists use the difference in density between the inner and outer core as evidence that the inner core is solid. This was proven using seismic waves traveling through the earth.
Because since secondary waves cannot pass through liquids or solids, and the waves can't pass thruogh the outer core than that means that the outer core is not soild.
Seismic waves than changes direction and speed because of the matter it's passing through and the moving from different matter's (Inner core-Outer core)
The P-wave is a compression / longitudinal wave and so unlike the S-wave is able to travel through the liquid outer core.
They go faster through the inner core than the liquid outer core.
