silica
it depends which one.
Yes
The silica content in magma has the greatest effect on its characteristics. High silica content makes magma more viscous and results in explosive volcanic eruptions, while low silica content produces runny magma and less explosive eruptions.
An example of a scientist using a conceptual model to describe a volcano is when they create a diagram illustrating the structure of a volcano, including features like the magma chamber, vents, and craters. This model helps to visualize how magma rises and erupts, as well as how different types of eruptions can occur based on the composition of the magma. By using this conceptual framework, scientists can communicate complex geological processes in a more understandable way.
1. Chemical Composition of the magma. 2. Concentration of the melt. 3. Presence of Volatiles. 4. Amount of Water present in the magma.
Scientists measure the silica content in magma to classify it into different types based on its composition. The silica content determines the magma's viscosity, which impacts how easily gases can escape and influences the type of volcanic eruption that may occur.
well magma is lava and its made from molten rock.
No
Their crystalline nature.
In a way. A magma is hotter then the surrounding rock, that's why the magma is molten and the rock is not. But because of this, some heat of the magma is melting the surrounding rock. You might want to classify this as erosion, but it's simply the melting of the rock surrounding the magma.
it depends which one.
The scientist was determined to get some magma to use in his research. Magma is the hot fluid that is in the Earth's crust.
Magma is the molten rock under ground. Once it is expelled from a volcano, it is called lava. They are two separate phenomena.
An intrusive igneous rock.
Yes
The ratio of the concentration (by weight) of an element (e.g. Ti) in a crystallizing mineralto its concentration in the magma. For example, KTi = [Ti]min./[Ti]magma, where kTi is the partition coefficient for Ti, and [Ti]min. and [Ti]magma are the concentrations of Ti in the mineral and magma respectively. The value of k is dependent on temperature, pressure and the composition of crystallizing mineral and magma.
Viscosity is the measure of a liquids resistance to flow. In the case of magma, the hotter it is, the lower the viscosity.
