Yes. If the magma stops in a magma chamber long enough it can change composition through two mechanisms:
- fractional crystalization, where minerals with lower melting points crystallize and sink to the bottom og the chamber
- Melting of srrounding rock, which then become part of the magma.
What else can I help you with?
At ocean-continent plate boundaries rising magma may change composition before reaching the surface?
At ocean-continent plate boundaries, the rising magma can interact with overlying continental crust, which can cause changes in its composition. This interaction can lead to the assimilation of continental rocks by the magma, altering its chemical composition before it reaches the surface. This process can produce volcanic rocks with unique characteristics compared to other types of magma.
Is a metal surface being ground a chemical change?
A metal Surface being ground is a physical change, not a chemical change.
What is one major difference in a physical change and a chemical change is?
Physical change, changes the appearance or the surface. Chemical change, changes the minerals inside the object. Physical deals with the appearance and the surface. Chemical changes the structure of the minerals inside the object.
The chemical properties of the aluminum change as you cut the can?
When you cut an aluminum can, the chemical properties of the aluminum do not change. The composition of the aluminum remains the same before and after it is cut. However, cutting the can may affect the physical properties of the aluminum, such as its shape and surface characteristics.
Does gasoline undergo a physical change before it burns?
Yes, gasoline undergoes a physical change when it evaporates before it burns. This change does not alter the chemical composition of the gasoline.
Are icicles forming on the edge of the roof of physical or chemical change?
No it is not. The chemical composition is H2O before and after freezing.
Is cutting your fingernails physical or chemical change?
Cutting your fingernails is a physical change because the composition of the material (keratin) remains the same before and after cutting. A chemical change involves a change in the chemical composition of a substance.
What two things are unaffected in physical change?
The chemical composition is not changed.
Is Cleaning a painted surface with acid a chemical or physical change?
Chemical broooooooooooooooo niga
A sheet of copper can be pounded into a bowl a physical or chemical change?
Pounding a sheet of copper into a bowl is a physical change because the copper is still the same substance before and after the change. The change in shape does not alter the chemical composition of the copper.
Is breaking of glass physical or chemical change?
It is a physical change. The resulting fragments of glass are still glass and of the same composition.
Why doesn't albedo change much over a day?
Albedo, the measure of how much sunlight is reflected by a surface, doesn't change much over the course of a day because it is primarily determined by the surface characteristics, such as color, texture, and composition. While the angle of sunlight can vary throughout the day, affecting the intensity of light reaching the surface, the inherent reflective properties of the surface remain relatively constant. Seasonal changes and weather conditions can influence albedo more significantly than daily fluctuations. Overall, the stability of surface characteristics contributes to the relatively consistent albedo values observed over short time frames.
