Basic lava, also called mafic lava, is a type of lava that consists of 50 percent silica. This type of lava is highly fluid and commonly creates large lava flows. Basic lava can reach speeds of up to 20 miles per hour and reach distances of 60 miles.
lava dome has a more vicious lava than of a shield volcano.lava dome is formed by relatively, small bulbous gases,however for the shield volcano it is made up of BASIC lava.the basic lava spreads ...
Basaltic lava is the most abundant lava on earth and is the lava most commonly depicted in pictures and media. In this lesson, we'll learn what defines basaltic lava and some of the different ...
The term lava flow is commonly shortened to lava. Although lava can be up to 100,000 times more viscous than water, lava can flow great distances before cooling and solidifying because of its thixotropic and shear thinning properties. Explosive eruptions produce a mixture of volcanic ash and other fragments called tephra, rather than lava flows.
Shield volcano/basaltic lava volcano/basic lava cone - A shield volcano is a wide volcano with shal-lowly-sloping sides. A shield volcano have a broad profile is built up over time by flow after flow of relatively fluid basaltic lava issuing from vents or fissures on the surface of the volcano. Many of the largest volcanoes on Earth are
Basic lava is the hottest lavas at about 10000 c and is highly fluid .it is dark coloured like basalt.rich in iron and mg but poor in silica
Lava: Magma that reaches the earth's surface is called lava. It may be acidic or basic. Acidic lava is viscous, is lighter in colour and has higher silica content. Basic lava is non-viscous, is darker in colour and has lower silica content. Gases: Gaseous compounds of sulphur and hydrogen, carbon dioxide, carbon monoxide and steam are released.
Lava is made up of crystals, volcanic glass, and bubbles (volcanic gases). As magma gets closer to the surface and cools, it begins to crystallize minerals like olivine and form bubbles of volcanic gases. When lava erupts it is made up of a slush of crystals, liquid, and bubbles. The liquid "freezes" to form volcanic glass.
The following are the some of the differences between Acidic and Basic Lava. Acidic lava is very viscous (sticky). Steep sides as the lava doesn't flow very far before it solidifies. Alternate layers of ash and lava. For this reason, they're also known as stratovolcanoes. Strato means layers. Longer periods between eruptions.
