Density is the measure of how many atoms are in a given space of a material. Basically, itâs how closely packed the atoms are in a material. To measure a materialâs density, you need to know how many atoms are in the material (the mass), and how much space it takes (volume).

A wind rose is a graphic tool used by meteorologists to give a succinct view of how wind speed and direction are typically distributed at a particular location. Historically, wind roses were predecessors of the compass rose, as there was no differentiation between a cardinal direction and the wind which blew from such a direction.
Wind is air that can be violent and dangerous. Wind forms when the heat from the sun heats the air particles from earth. Hot air rises so the hot air begins to rise. The cool â¦ air of the earths higher atmosphere cools the air so it begins to sink the process continues over and over to create wind. This can form tornado's and hurricane's.
