Description This is a picture of a volcano named Popocatepelt. which is found on Mexico. This volcano as others parts of the Earth it use physics, Some of the categories of physics in a volcano are weather, heat and states of matter.


 * Weather **

How the weather is influence by volcanos? - When volcanos make eruption, they emit a mixture of gases and particles into air. Some of this mixture the are send to the lower stratosphere of the earth are ash,blast gas and sulphur dioxide, when this mixtures are combine with the air, its have a impressive effect on the earth which cause a reflect sunlight away from the earth, an significant dip in global temperatures for years. The volcanic haze scatters cause the some of the incoming sunlight back to the space, and reducing solar heating of the earth's surface, This change is name "Climate forcing". Thanks this information, it helps to predict, how the climate will change in response volcanos.

How heat works in volcanos? One definition for volcano heat, is surface manifestation of a planet internal heat processes. Inside the earth is found lava river, a destructive pyroclastic explosions, and quietly degassing fumaroles are all processes that are ultimately driven by heat. H eat released as a byproduct of radioactive decay, a residual heat leftover from the formation of the Earth. Heat of the volcano is released when an atom of a radioactive element experiences decay. Decay is the ejection of a particle that occurs in order to bring the atom to a more stable configuration. Radioactivity is a natural, ongoing process and is not a human invention. Over all i found on this page the heat is not yet completely understood.
 * Heat **

Three Staates of matter on volcanos are solids, liquids and gases. Lava is rock called magma or crust, Crust is one of the states of matter before it coverts to liquid, When this becomes liquid this flows on the surface one of the earth. The lava is formed by crust(A solid) of the earth, which are extremely heat. there are many changes the occur to lava which shows the states of matter. first is as it cools, then the lava changes to state, from solid to liquid and as its heat this changes to gasses such as carbon dioxide, hydrogen sulfide and water vapor, which are send to atmosphere. The volcano use states of matter, solids, liquids and gases First when the rocks of lava/ crustal are solid like crustal rocks, and mantle materia. Later this rocks are melt(liquid) to a response of decreasing in pressure. Between 20 and 300 km below the surface, this changes of temperature and pressure conditions allow a phase change from solid to liquid. After the rocks are melt the volcano, erupt's at the surface, and produce volcanic activity which cause a mixture of gases into the earth and this affect the weather.
