What are the properties of magma?
Properties of magmas Magmas consolidate at the surface as lava flows (volcanic), or fall as lithic (rock), crystal and/or glass fragments (pyroclastic). Some solidify within the earth (plutonic or subvolcanic rocks). The properties of magmas include temperature, density, viscosity, gas content and abundance.
What is magma quizlet?
Magma. Molten rock found beneath the earth’s surface. Lava.
Why do different liquids have different viscosities quizlet?
Why do different liquids have different viscosities? In some liquids, there is a greater degree of friction among the liquid’s particles. These liquids have higher viscosity than liquids whose particles have a lesser degree of friction.
What’s the difference in silica content and viscosity between light colored and dark colored magma?
Magma that is high in silica produces light-colored lava that is too sticky to flow very far; ex. Rhyolite. The less silica magma contains, the lower its viscosity. Low-silica magma flows readily and produces dark-colored lava; ex.
What are the three components of magma?
Magma and lava contain three components: melt, solids, and volatiles.
What two properties distinguish magma from lava?
Magma:
| Difference Between Magma and Lava | |
|---|---|
| Magma | Lava |
| The molten rock that is present beneath the surface of the earth is termed as Magma. | The molten liquid that gets erupted out of the surface of the Earth is termed as Lava. Lava is also referred to as Liquid Magma. |
What is the main difference between magma and lava quizlet?
Magma and lava both refer to molten rock from which igneous rocks form. However, magma refers to molten rock below Earth’s surface, and lava refers to molten rock at the surface.
What are the two main factors that determine the viscosity of magma?
a. The viscosity of a magma is affected by its silica content and temperature. The amount of silica influences the magma’s viscosity in such a way that if the silica content is low, the magma would have low viscosity, whereas a high content of silica would make the magma more thick and sticky.
What sequence of events could lead to magma becoming soil quizlet?
Exposure, weathering, and erosion. What sequence of events could lead to magma becoming soil? Cooling and hardening followed by erosion and deposition.
What are the physical and chemical properties of magma?
Several interrelated physical properties determine the characteristics of magma, including chemical composition, viscosity, dissolved gases, and temperature. Molten, or hot liquefied, rock located deep below Earth’s surface is called magma.
What is magma made of quizlet?
Most magmas consist of three materials: a liquid component, a solid component, and a gaseous component. The liquid portion, called melt, is composed mainly of mobile ions of the eight most common elements found in Earth’s crust—____..
What are the three major components of all magma?
Magma and lava contain three components: melt, solids, and volatiles. The melt is made of ions from minerals that have liquefied.
What are three main types of magma what factor determines these classifications?
Types of magma are determined by chemical composition of the magma. Three general types are recognized: Basaltic magma — SiO2 45-55 wt%, high in Fe, Mg, Ca, low in K, Na….Temperature of Magmas
- Basaltic magma – 1000 to 1200oC.
- Andesitic magma – 800 to 1000oC.
- Rhyolitic magma – 650 to 800oC.
Which of the following characteristics of magma determine its explosiveness?
Viscosity, together with the amount of gas dissolved in magma, can determine the explosivity of the eruption. More viscous magma with volatiles is more explosive than less viscous magma, where gases can bubble out relatively easily.
Which temperature is typical of magma?
Temperature. Temperatures of lava, which is magma extruded onto the surface, are in the range 700 to 1,400 °C (1,300 to 2,600 °F), but very rare carbonatite magmas may be as cool as 490 °C (910 °F), and komatiite magmas may have been as hot as 1,600 °C (2,900 °F).
What happens to hot lava after it erupts from a volcano gizmo answers?
What happens to hot lava after it erupts from a volcano? The lava runs like water to the lowest point then hardens.
What are the 4 types of magma?
Because many of the properties of a magma (such as its viscosity and temperature) are observed to correlate with silica content, silicate magmas are divided into four chemical types based on silica content: felsic, intermediate, mafic, and ultramafic.
What is Magma made up of?
What is magma’s major ingredient? silica silica the compound is made up of particles of the elements oxygen and silicon-one of the most abundant materials in Earth’s crust The silica content of magma?
What does magma with high silica look like?
the more silica magma contains the higher its viscosity what does magma look like that is high in silica? light colored lava that is too stick to flow very far-when it cools it forms rhyolite which has same composition as granite What does low silica magma look like?
What is magma’s viscosity?
the viscosity of magma depends upon its silica content and temperature What is magma’s major ingredient? silica silica the compound is made up of particles of the elements oxygen and silicon-one of the most abundant materials in Earth’s crust The silica content of magma? it ranges from about 50-70 percent
How does silica content affect the viscosity of magma?
The more silica the magma contains, the higher its viscosity and the slower it moves. The less silica the magma contains, the lower its viscosity and the faster it flows. What is the difference in silica content and viscosity between light-colored and dark-colored magma?
