Seismic waves change speed as they travel through Earth because of the four different layers. The layers differ, changing from a thin crust, to a rocky mantle, a liquid outer core, and finally a solid metallic core. Each of the layers affect the speed of seismic waves due to the differences in their makeup. They move faster through the crust and mantle than they do through the cores. In fact, "S" waves are unable to move through the liquid outer core at all.
Depending on the material, a wave can become propagated, compressed, and expanded. This can happen at different parts of the wave resulting in different sounds.
Yes they do indeed

Sulfur itself is pure because it is an element, but many things can combine with sulfur to create different minerals.
It makes rock, etc. move to different areas which causes more things to happen!
Light waves do not pass through opaque materials. Light is absorbed or reflected by opaque things. To be sure there is some scattering, nothing is entirely absorbent.
Circulation
The light bends and it is separated in the different colors of the rainbow.
Nope. Digital materials are handled exactly the same as physical materials.
Lots of different things happen in a week once: i stubbed my toe and then the next day the guy i liked said hi to me

To let things through the cell membrane
Light travels through different things (such as air, water, glass, plastic) at different speeds. When a light wave is passing one substance and encounters another (for instance, traveling through air and gets to glass), the difference in the speed causes the light wave to bend. This is what causes rainbows and a spectrum and fish to appear in a different place than where they really are.
proactivity
two things that may happen to the meteoroid is that it might burn or collide with the Earth.
Bad things can happen at any time of the year, and there is no specific reason why they may occur more frequently in September. Many factors can contribute to the occurrence of negative events, including individual circumstances, environment, and random chance. It is important to focus on how to cope with and overcome challenges, regardless of when they occur.
Three different things happen to the solar energy that earth receives. Some escapes back into ____________, some is absorbed by land and water ____________________.
Materials can be made of all sorts of elements so it depends what material you mean.Atomsmatter. lots of different things. cotton. etc.
You need a design for a helicopter. That design will tell you what materials you need...because every heli has different materials in it. The things you need to build a Robinson R-22 are different from the things you need to build a Sikorsky CH-53E.
