Subduction is when one tectonic plate goes underneath another. It occurs when two tectonic plates push against each other and the denser one goes underneath. This forms mountain ranges.

Why do some objects float while others sink?

# data[].attributes.body
The reasoning behind why objects sink or float is all related to density. Every object on our earth have their own individual densities, which means some objects are going to be lighter or heavier than others. For example, if you were to put a nail in water, the nail would sink. The reason the nail would sink to the bottom and not float to the top is caused by the nail having a heavier density than the water.

Density is relevant to my life because everything has a density and it controls why some materials are "heavier" than others that appear to have the same mass (but actually have the same volume). Everything around us has density; liquids, solids, even you! This is the reason why density is so relevant to our lives because every object has it. The density of an object will remain the same if the temperature and pressure don't change.  This makes density a useful physical property for indentifying a substance.

As you can see, each liquid in this display have their own densities; vegetable oil being the least dense and honey being the most dense.  Honey had a density of 1.33 g/mL while vegetable oil has a density of 0.93 g/mL.

Similar to solids, liquids are made from atoms and molecules, which have a certain mass and size. Liquids have their own densities depending on the mass of the molecules that make up a liquid and how tightly they are packed together. Oil is less dense than water because is is made from carbon and hydrogen, carbon being lighter than oxygen.

Liquid water is actually slightly denser than ice, so ice floats on top. Fun Fact! The reason we are able to have life on the earth is owed to the fact that ice is less dense than water. Ice, like glaciers and land forms, reflect radiation from he sun back into outer space, regulating climate so we do not suffer from extreme heat issues. if ice were to be more dense than water and sink to the bottom of the ocean, the sun's radiation would stay trapped in our atmosphere. The climate would reach to a point where life nor marine life would survive.

When weighing gold it is the 'density' that is measured. The density of gold is much higher compared to many other metals.
What is the density of gold if the volume is 3 cubic centimeters (cm³⁾and it has a mass of 57.96 grams?
D=m/v
D=57.96g/3cm3
D=19.32g/cm3

Density= Mass/Volume
