Document Summary
Less dense materials float on top of denser materials. Least dense to most (1-6): atmosphere, ocean, crust, mantle, outer core. Earth materials: iron > nickel > oxygen: earth core, earth crust, ocean, atmosphere: nitrogen > oxygen > argon oxygen > silicon > aluminum oxygen > hydrogen > chlorine. Viscosity: how thick a fluid is, depends on temp & chemical structure, more viscosity more thick, slower. Forces: a force pushes or pulls, n = kg m / s^2. Gravity: a force that attracts matter to each other. Is the force that pushes an object: w = fd, si unit of work and all energy is joules (j) The work needed to raise an object: pe = mgh. Kinetic energy (ke: any moving object possesses kinetic energy, ke = 0. 5 m v^2. Sensible heat: heat energy we can sense or feel (or measure, when we measure temp, we are measuring sensible heat. Hidden heat energy in chemical bonds between atoms.
