it's a simple question why can't anyone answer it is anything wrong with everyone

The speed of a wave is determined by the medium it is traveling through and the properties of that medium, such as its density and elasticity. In general, the speed of a wave is faster in a more rigid and less dense medium, and slower in a less rigid and denser medium.
The lithosphere is the solid outer section of Earth, which includes Earth's crust, and the underlying cool, dense, and rigid upper part of the mantle.
The inner segment of the Earth that is rigid, dense, and solid is the inner core. It is believed to be composed mainly of iron and nickel, with temperatures reaching up to approximately 5,700°C (10,300°F). The immense pressure at the center of the Earth keeps the inner core solid despite its extremely high temperatures.
Ice particles form rigid crystalline structures. Liquid water is more fluid and dense.
Iron in solid form is more dense because the particles are rigid and connected in a structured shape. Iron as a liquid is less dense because the particles are not rigid/not connected and flow.
when liquid water cools the molecules come closer together, water is most dense at 4 degrees Celsius and anything less there is vibrational movement and the hydrogen bonding are more rigid. at this point water expands as it freezes, meaning ice is more dense than water causing it to float.
