Question 19 1 1 pts Based on Lab Exercise 1. Identification of Igneous Rocks. Which of the following statements best describes Sample 11.
Magma contains the same elements as Earths crust. It formed quickly in mid-air from felsic lava. What location is associated with the composition of the magma that formed Sample 5.
It formed slowly underground from felsic magmaCorrect. A motion that takes place inside cracks that infiltrate the upper mantle C. Specimen 9 crystallized from a felsic magma.
Which of the following statements best describes Sample 1. Minerals do not crystallize from magma in random order but instead crystallize based on temperature. Magma varies widely in composition.
Felsic magmas are higher in silica and contain lighter colored minerals such as quartz and orthoclase feldspar. Magma contains only three elements. Magma Volcanism and Igneous Rocks.
Which of the following best describes the composition of the magma that erupts at Mount Pinatubo in the Philippines. Magma contains the same elements as snowC. Which statement best describes the composition of magma.
Second felsic magmas tend to have higher levels of volatiles. Which statement best describes what happens during a chemical change. The words that describe composition of igneous rocks also describe magma composition.
2 Choose the most likely product of partially melting a rock of intermediate composition. Felsic magmas are higher in silica and contain lighter colored minerals such as quartz and orthoclase feldspar. Mafic magmas are low in silica and contain more dark magnesium- and iron-rich mafic minerals such as olivine and pyroxene.
As up welling brings soft rock upward from deeper mantle pressure decrees 2. Which statement describes the composition and viscosity of the lava associated with shield volcanoes. Minerals that dont melt are left behind.
Oxygen silicon aluminum iron calcium sodium magnesium and potassium Figure 36. Which statement correctly describes the relative dating of rocks1 point A. Lava is the viscous material that flows on the Earths surface and magma is the solidified material after exposure to low temperature.
Magma contains the same elements as snowC. Specimen 8 is rhyolite. -best describes the composition of magma.
10 Which Statement Best Describes the Composition of Magma Rocks can only be made up of a combination of three types of mineral. - best describes the composition of magma. The most abundant volatile in magma is water H 2 O followed typically by carbon dioxide CO 2 and then by sulphur dioxide SO 2.
Question 20 1 1 pts Based on Lab Exercise 1. A geological phenomena that occur on the surface of the earth B. Magmas can vary widely in composition but in general they are made up of only eight elements.
It is thought that separate magma chambers can undergo mixing via the creation of connections between the two chambers. A process correlated with the flow and transportation of igneous material. A mafic magma.
Identify the statement that best describes the role of magma mixing in altering magma composition. 1 1 ptsQuestion 5 Based on Lab Exercise 2. That is components that behave as gases during volcanic eruptions.
Magma contains the same elements as Earths crust. In order of importance. It can only be used for rocks more than a million years old.
The higher the amount of silica in the magma the higher is its viscosity. Magma contains only three elementsD. Magma contains the same elements as Earths crust.
Mafic magmas are low in silica and contain more dark magnesium and iron rich mafic minerals such as olivine and pyroxene. Magma contains only three elements. Oxygen the most abundant element in magma comprises a little less than half the total followed by silicon at just over one-quarter.
Stages of iron rich magma 1. Magma is an element all its own. Lava is synonymous with magma which is found beneath the Earths surface.
The collapse would have been a result of a gradual subterranean drainage of a central magma chamber. Magma contains the same elements as Earths crust since this is where the Magma originates from. Decreased pressure results in partial melting of the rock to form a magma with mafic comp.
It formed from felsic lava as gas bubbles escaped. It formed quickly on the surface from mafic lava. Magma is the molten material beneath the Earths surface and it is called lava if it flows on the surface.
