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?
magnetite
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.
What is the difference between trap rock and granite rock?
Traprock is any of the various, dark-colored, fine-grained igneous rocks, such as basalt, that is primarily used as crushed rock for road construction. Granite rock on the other hand, is any of the various light-colored, coarse-grained igneous rocks that is used in building construction and architectural design.
What property is common to most dark-colored igneous rocks?
Most dark-colored igneous rocks have a high density.
What property is common to most dark colored igneous rocks?
Most dark-colored igneous rocks have a high density.
The moon is made of rock called what?
The moon is made of basalt rock. Basalt rock is igneous, dark colored, and fine grained. Similar rock can be found in Antarctica and Hawaii.
Light-colored igneous rocks are less what than dark-colored igneous rocks are?
less dense
What is dark colored rocks called?
igneous
What is a dark colored rock?
Mafic igneous rocks, like basalt, are dark colored and low in silica.
How does the density of a light colored rock differ from the density of dark colored 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.
What is an intrusive igneous rock that is dark colored?
gabbro
What is a dark fine grained rock called?
They are rocks formed from lava at or near the surface. Basalt is a typical fine-grained extrusive igneous rock, composed of mineral crystals that require magnification to see. The fine-grained texture is due to rapid solidification of the lava which leaves little time for large mineral crystal formation.
