How do you use lava mafic and felsic in one sentence?
Lava can be classified into two main types: mafic lava, which is rich in magnesium and iron and tends to flow easily, creating broad shield volcanoes, and felsic lava, which is high in silica and more viscous, leading to explosive eruptions and the formation of stratovolcanoes.
Name the two types of lava?
The two main types of lava are pahoehoe, which has a smooth, rope-like texture, and aa, which has a rough, jagged texture. They differ in their viscosity and flow characteristics, with pahoehoe being more fluid and aa being more viscous.
What are the two types of magma?
The two main types of magma are mafic and felsic.
What are the main features of a volcanoes?

What types of debris comes out of volcanoes?
Volcanic materials are divided into two main groups: Pyroclastic materials and lava flow materials.
Are there three types of lava or four?
It depends on what criteria you use. If you go with the kind of flow there are four.Pahoehoe (ropey lava flows)A'a (jagged, more viscous flows)Pillow lava (rounded lumps that form underwater)Block lava (very viscous, very slow moving)The first three are all associated with mafic lava, also called basaltic lava, which refers to a specific composition. Pillow lava is sometimes ignored as are black lava flows, which don't much resemble traditional images of lava.In terms of composition there are also 4 basic types on a spectrum of increasing silica content and viscosityMafic (basaltic)Intermediate (andesitic)Intermediate-felsic (dacitic)Felsic (rhyolitic)These can be further subdivided. Another, rare kind of lava exists called carbonatite. This strange lava is composed of carbobnates rather than silicates as the others are, and is only found in one volcano: Ol Doinyo Lengai in Tanzania.
3 main groups of igneous rocks?
The three main groups of igneous rocks are intrusive (plutonic), extrusive (volcanic), and hypabyssal rocks. Intrusive rocks form below the Earth's surface from the slow cooling of magma. Extrusive rocks form on the Earth's surface from rapidly cooling lava. Hypabyssal rocks are intermediate rocks that form from magma that solidifies in the crust.
What are the main magma rocks?
Felsic, high in silica. Mafic, low in silica. Intrusive, those formed underground. Extrusive, those formed above ground.
What are two types of magma?
The three types of magma are basalt, andesite, and rhyolite. Basalt is flowing and is usually around 1,200 degrees Celsius. Andesite is flowing and explosive and is usually between 800 to 1,000 degrees C. Rhyloite is very explosive and is usually at 750 to 850 degrees Celsius.
What materials are used to make jets?
If you are asking about carburetor jets, then they are made from brass. Jet engines, are made with many different materials, the main one probably is titanium.
