         <description><![CDATA[<div>Physical properties are quantitative observations that can be made about an object without changing its chemical composition (color, texture, etc.). Physical changes simply alter or effect the form of an object without changing its chemical composition (Like matter changes). The reason this vocabulary term is located near a volcanic site, is because volcanoes maintain many processes that reflect physical changes and properties. As example, liquid magma exploding onto the surface to become lava and then overtime cooling down to be rock display physical properties and physical changes. (As of now there isn't really any similar vocab words to physical properties or change.)</div>]]></description>

         <description><![CDATA[<div>A property of water also includes how cohesive this substance is, meaning how close together the particles are  either allowing the substance to be runny or slow and thick like molasses. Understanding this, the best term to tie the Properties of water with will be convection. Convection currents are the circling of hot and cold currents,  where heat rises and cold currents sink. With water being lightly cohesive (meaning it is liquid and runny, particles are not too close together) these currents can easily rise and set.</div>]]></description>

         <description><![CDATA[<div>The Law of Conservation of Energy claims how energy cannot be created nor destroyed, but transferred. It's literally everywhere, and explains how different systems and surroundings gain and lose energy. :D</div>]]></description>

         <description><![CDATA[<div>The states that the total energy of an isolated system remains constant; it is said to be conserved over time. This law means that energy can neither be created nor destroyed; rather, it can only be transformed or transferred from one form to another. I placed this here because of how the earth transfers heat energy into different forms through different processes, for example radiation.</div>]]></description>
