High silica magmas can explode violently as its high viscosity causes a greater build up of pressure inside the volcano. Magmas low in silica tend to produce volcanic eruptions that are runny because of low viscosity.
A liquid is a compound or a mixture; the chemical composition is representative for this liquid.
when 2 or more compounds react chemically to form a new compound then it is called chemical reaction chemical reaction whereas the quantity and no. chemical elements presents in chemical compound is called the chemical composition
A physical change is different than a chemical change, because in a physical change, the composition of the matter did not change. While in a chemical change, the composition of the matter did change.SO basically, the composition of the matter does not change is the difference between a physical change and a chemical change.yes

The island of Iceland is situated at the join between two tectonic plates. These joints between plates are the places where volcanoes occur throughout the world as liquid rock (magma) can easily seep up between the plates causing volcanic activity.
The nitrogen is different between the two.
A liquid is a compound or a mixture; the chemical composition is representative for this liquid.
Physical properties can be observed without changing the chemical composition of a substance. Chemical properties can only be observed by changing the chemical composition of the substance. In a physical change, the chemical composition of the substance does not change. In a chemical change, the chemical composition of the substance changes.
The hot spot volcanic activity is not dependent on the subduction and melting of oceanic crust. The hot spot simply appears to be a non-moving place in the Earth's mantle where heat rises from the interior.
The easiest way to distinguish between volcanic ash and volcanic dust particles is to compare their diameter. Seismographs can be useful in predicting volcanic eruptions because they measure earthquake activity.

A chemical change results in a change in chemical composition, while a physical change does not.
Phase has nothing to do with chemical composition.
The size, atmosphere, composition, and crust activity.
