Because the sun and stars are emitting them constantly and we would be irradiated - i.e. life would not exist (at least not above ground - and/or as we know it)

body waves
earthquake waves travel through the earths crust.
Elastic waves, particularly sound waves and seismic waves, can travel through the Earth's atmosphere. Sound waves propagate through the air, while seismic waves are generated by earthquakes and travel through the Earth's crust and mantle.
Radio waves are the type of electromagnetic radiation that can pass through the atmosphere most easily. This is because they have the longest wavelengths and the lowest frequencies of all types of electromagnetic radiation. Radio waves can also pass through solid objects, which makes them useful for a variety of applications, such as broadcasting, communication, and remote sensing.
Yes, radio waves can penetrate Earth's atmosphere. They are part of the electromagnetic spectrum and are able to pass through the atmosphere with minimal interference, which allows them to be used for various forms of communication, such as radio and television broadcasts.
S-waves are not transmitted through the 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.
Seismic waves are the types of waves that can travel through the Earth and along its surface. There are two main types of seismic waves: body waves (such as primary and secondary waves) that travel through the Earth's interior, and surface waves (such as Love and Rayleigh waves) that travel along the Earth's surface.
True. Light waves have a much shorter wavelength compared to sound waves, making them more easily bent or diffracted when passing through different mediums. This is why we often observe phenomena like rainbows or sunsets, where light waves are scattered or bent by particles in the atmosphere.
