What rock forms light colored lava?
The rock that is formed from light-colored lave is called rhyolite.
What rock forms from light-colored lava?
Rhyolite is a common rock that forms from light-colored lava. It is composed mainly of silica-rich minerals such as quartz and feldspar, giving it a light color. Rhyolite has a fine-grained texture and often contains small crystals.
The rock forms from light-colored lava?
Rhyolite or Rhyolyte (Cant be exact on spelling but its the thought that counts)
Is it true that magma that is low in silica usually forms light colored rocks?
Magma doesn't produce lava. Magma is lava. Magma is called magma when it is under the ground but when it is released via a volcano it is called lava when it is above ground. The magma or lava can produce dark to light color rocks after it cools depending on the composition of the magma or lava. There is also a range in the color of the lava depending on it composition and temperature also.
What are 3 types of igneous rocks?
Basalt: a dark-colored, fine-grained rock that forms from rapidly cooled lava. Granite: a light-colored, coarse-grained rock that forms from slowly cooled magma deep within the Earth's crust. Obsidian: a shiny, black volcanic glass that forms from rapidly cooled lava without crystallization.
Name 4 types of igneous rocks?
Intrusive Extrusize Plutonic and Hypabyssal
What kind of rocks make up most of the igneous group?
Most igneous rocks are formed from two main types of rocks: basalt and granite. Basalt is a fine-grained, dark-colored rock that forms from rapidly cooled lava, while granite is a coarse-grained, light-colored rock that forms from slowly cooled magma beneath the Earth's surface.
What is the difference in silica content and viscosity between light-colored and dark-colored magma?
The lower the viscosity is the hotter the magma is and faster it flows.Higher the viscosity is the cooler it is and slower it flows down.
Does Light-colored rocks with lower densities form from basaltic magma?
Basaltic Magmas are dark colored, heavy and are ferromagnesian in composition, so they most times do not form light colored rocks, rather, the Felsic Granitic Magma forms the light colored rocks with lower densities.
Does Dark colored Basalt Rock have low viscosity?
Rock itself is solid and so does not have visocosity. However, the lava that forms basalt is low viscosity.
Why does rock pocket mouse color influences its overall fitness?
Because of natural selection, most of the light-colored mice live on light rocks, while most dark-colored mice live on dark lava rocks.
What type of rock forms when lava cools very quickly?
igneous with small crystals. Extrusive igneous rock forms from the solidification of lava. Rocks such as rhyolite, pumice, obsidian, and basalt. Igneous rocks are formed by magma (inside the earth) or lava (outside earth) that cools and hardens. Extrusive rocks are rocks thathave exited the earths surface.
