the top layer because,the bottom of the sea makes waves till it gets to the top
P-waves(primary waves) travel faster than S-waves(secondary waves)
waves that travels only on the surface
It's not radio active waves; it's just radio waves. It's called the Ionosphere and depending on what layer of the Ionosphere it changes how far you can talk
The ionosphere is the layer of the atmosphere that reflects radio waves. This layer is able to reflect specific frequencies of radio waves back to Earth, allowing for long-distance communication using radio signals.
The layer that reflects radio waves of low frequency is the ionosphere layer known as the D-layer, which is located at an altitude of approximately 50-90 kilometers. Radio waves of low frequency, such as medium frequency (MF) and lower high frequency (HF), bounce off this layer for long-distance communication.
The ozone layer contains electrical charged particles that reflects radio waves
S-waves are not transmitted through the outer core.
Lonosphere
Ionosphere
the lonosphere
The "F" layer is high altitude region of ionized atoms that reflects radio waves.
Direct Answer: AsthenosphereExplained Answer: Earthquake waves normally go faster with increasing depth. However, below the lithosphere, the upper mantle contains a curious layer in which earthquake waves unexpectedly slow down. Geologists call this layer the asthenosphere.
