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.
Do exterior walls painted with a dark colored paint require repainting more often that walls painted with a light colored paint?
Dark exterior colors absorb heat and ultraviolet rays which are both very oxidizing elements therefore dark exterior finishes generally chalk up sooner and require more frequent maintenance
How does the amount of heat energy reflected by a smooth dark-colored concrete surface compare with the amount of heat energy reflected by a smooth ligh-colored surface?
The dark coloured concrete surface absorbs more heat energy and therefore reflects less heat energy.
What color is peridotite?
The igneous rock peridotite has a very high color index. It is comprised of more than 95% mafic minerals (like olivine), giving it a dark green color.
What combination of colours to make deep bronze green?
Most likely black maybe a dark gray.
This igneous rock is coarse-grained. The dark-colored mineral composing this rock is probably?
The dark-colored mineral in coarse-grained igneous rocks is likely to be biotite or hornblende. These minerals are commonly found in rocks like diorite, gabbro, and basalt.
Dark colored igneous rock rich in iron and magnesium?
Dark, mafic rock is relatively rich in iron and magnesium.
What are two examples of fine-grained igneous rock?
Two examples of fine-grained igneous rocks are basalt and rhyolite. Basalt is a dark-colored rock with a composition rich in iron and magnesium, while rhyolite is light-colored and has a high silica content. Both rocks form from the cooling and solidification of molten magma.
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 are three types of igneous rock?
Three types of igneous rocks are basalt, granite, and obsidian. Basalt is a dark-colored fine-grained rock, granite is a light-colored coarse-grained rock, and obsidian is a natural glass formed from rapidly cooled lava.
What is the igneous rock that is dense and dark colored and forms from magma that is rich in iron and magnesium but poor in silica That has 8 letters?
The igneous rock you are referring to is basalt. It is a fine-grained, dense, and dark-colored rock that forms from low-silica magma rich in iron and magnesium.
What is the dark colored igneous rock with rich in iron and magnesium?
The dark-colored igneous rock rich in iron and magnesium is called basalt. Basalt is a fine-grained rock that is commonly found in volcanic areas and oceanic crust. It is characterized by its dark color due to the presence of minerals like pyroxene and olivine.
How does the density of a light colored igneous rock differ from that of a dark colored igneous rock?
Normally, light colored igneous rocks are less dense compared to dark colored igneous rocks. This is because the light colored rocks have a less iron in them.
Light-colored igneous rocks are less what than dark-colored igneous rocks are?
less dense
What is dark colored rocks called?
igneous
What factors affect the texture of igneous rock?
The cooling rate of magma is the primary factor that affects the texture of igneous rocks. Rapid cooling results in fine-grained texture, while slow cooling leads to coarse-grained texture. The mineral composition of the magma also influences the texture, with high silica content producing light-colored and fine-grained rocks, and low silica content resulting in dark-colored and coarse-grained rocks.
What is a dark colored rock?
Mafic igneous rocks, like basalt, are dark colored and low in silica.
