What happens when s waves hit the outer core of earth?
Because the Earth's core is liquid; S-waves can't travel through liquid.
How do people now about earth layers?
From earthquake waves. There are 2 types of waves, p or primary waves and s or secondary waves that are generated when an earthquake occurs. Both types of waves move away from the epicenter of the earthquake in all directions including "down" through the layers of the Earth under the epicenter. Both waves start out at the same time from the same spot, but P waves move through the earth faster, hence the name primary waves. The farther the earthquake monitoring equipment is from the epicenter the bigger the lag time between when the p and s waves arrive. Monitoring stations on the side of the Earth opposite the epicenter do not receive any S waves. This is because S waves only move through solids so when the S waves hit the liquid outer core, the energy from these waves dissipates. When you move out far enough perpendicularly from the epicenter, S waves show up again on monitors. By overlapping these "shadow zones" from multiple quakes around the world, the depth at which the liquid outer core begins can be determined.
What happens when plates meet?
Well I know when two plates collide the plates form a mountain and when they hit each other theres a crack on earths crust and a earth quake happens
What are rocks that hit the earth?
meteorites are rocks that hit the earth meteors have not
How do seismic waves behave when they encounter a fault?
the seismic waves work when the erosion happened in the middle of the ocean and then they burn so they explode!!
What happens if thunder hits earth?
Thunder is sound waves. They hit Earth all the time, and nothing in particular happens.
How do different obstacles affect radio waves?
Radio waves hit all obstacles the same, but the waves will differ in the distance of the wave and/or the object from the transmitter.
What causes the fluttering of radio reception when an airplane flies overhead?
okay fluttering is due to reflection/interfearence of sound waves between an aeroplane and the radio.therefore this is what happens when the radio station send the radio waves directly a radio receive the waves but fluttering occurs when an aeroplane interfearring the path of transmission where by some of the waves form radio station will hit an aeroplane and goes to a radio and also part of the wave will go direct to a radio therefore simultaneously receiving of radio form two different places is what causes fluttering!
Do radio waves hit the ionosphere?
Yes. The result is that some fraction of the radio energy, depending on its frequency and ranging from none of it to all of it, is bent back down to Earth. The rest continues on through the ionosphere into space.
When sound waves hit a barrier nothing happens?
the sound waves reflect back
What happens to seismic waves when they hit the MOHO?
They speed up
What happens when an earthquake occurs far from an observing station?
P-waves hit, followed by S-waves, followed by surface waves.
What happens to sound or light waves when they hit a smooth surface?
They are reflected :)
What happens when electromagnetic waves hit an object?
The Moon Perpendicular to the sun
What happens when lightning hit earth?
it might smoke a tiny bit where it hit the earth
What happens when sound waves hit the water?
makes little ripples in the water
What is electromoagnetic waves?
Electromagnetic waves refer to a whole family of waves that are emitted by moving charges. These include gamma rays, xrays, ultraviolet light, regular light, infrared light, microwaves and radio waves. They all have the same basic characteristics but have dififferent frequency and wavelength ranges. They are made up of electric and magnetic fields. These fields can exert forces on charges they hit and cause them to move. So radio waves emitted by a radio station transmitter travel thru space and hit the antenna in your radio. This causes the charges in the antenna to move which is then converted back into sound. Light waves that hit your arm cause the charges to move and you feel warm etc.
