What is mafic lava like?
Mafic lava is low in silica and high in iron and magnesium, which makes it less viscous and more fluid compared to felsic lava. It tends to flow easily and often forms basaltic rocks when it cools. Mafic lava eruptions typically result in gentle, effusive lava flows rather than explosive eruptions.
Does paricutin mafic or felsic lava?
Paricutin volcano in Mexico predominantly erupted mafic lava, which is rich in magnesium and iron and has a low silica content. This type of lava tends to flow more easily compared to felsic lava.
Which moves fast felsic lava or mafic lava?
A mafic lava flow will move faster than a felsic lava flow due to its lower viscosity. However, felsic magma tends to erupt explosively, producing fast-moving pyroclastic flows instead of lava flows.
How do you list characteristics of mafic and magma?
Mafic magma is high in magnesium and iron, has a low silica content, and is less viscous compared to felsic magma. Mafic lava typically produces dark-colored rocks like basalt and is associated with oceanic crust. Mafic magma tends to erupt more quietly and flow more easily due to its lower viscosity.
Does mafic magma explode?
Mafic magmas generally have lower viscosity and gas content compared to felsic magmas, so they tend to flow more easily rather than explode. However, in certain conditions where gas build-up is high and pressure is released rapidly, mafic magma may still explode, but it is less common than with felsic magmas.
Is the composition of the hawaiian lavas felsic or mafic?
The composition of Hawaiian lavas is typically mafic, as they are rich in magnesium and iron and have a lower silica content. This composition gives them low viscosity and allows them to flow easily.
Is flow of lymph through lymph nodes fast or slow compared to blood capillaries?
The flow of lymph is slow because the lymphatic system has no pump.
If a lava flow at earths surface had a basaltic composition what rock type would the flow likely be?
A Mafic Extrusive Igneous Rock.
Why do mafic magmas tend to reach the surface much more often than silicic magmas?
Mafic magma is less viscous or more fluid than silicic magma in much the same way that water is less viscous than molasses. Mafic magma reaches the surface more often because it flows more easily.
What are the characteristics of mafic magma?
Mafic magma is characterized by its high content of magnesium and iron, resulting in a darker color and higher density compared to felsic magma. It typically has a lower viscosity, allowing it to flow more easily, which often leads to less explosive volcanic eruptions. Mafic magma is commonly associated with divergent plate boundaries and hotspot volcanoes, producing basaltic lava flows. Additionally, it usually contains fewer silica and gas components than its felsic counterpart.
Fast moving hot lava that has low viscosity is called?
Fast moving hot lava with low viscosity is called "pahoehoe." It has a smooth, ropy texture due to its high temperature and low resistance to flow.
Does eletricity flow fast or slow?
Compared to molasses, water in the olde mill stream, or traffic on the interstate highway, electric current flows very fast. Compared to the speed of light, in vacuum and in most material media, electric current flows slower.
