Yes, dark gray rock can reflect light, though its reflectivity depends on factors such as its mineral composition, surface texture, and moisture content. While darker colors generally absorb more light than lighter colors, many rocks have shiny surfaces due to minerals like quartz or mica, which can enhance reflectivity. Additionally, polished or smooth surfaces will reflect more light than rough, matte surfaces.

What does not give off its own light?
People, trees, flagpoles, most animals (although the Japanese have bred "glow in the dark" fish and cats) , planets, moons, and other items that only REFLECT light.
Does a meteor emit light or reflect light?
A meteor emits light as it burns up in the Earth's atmosphere. This is due to the intense heat generated by friction with the atmosphere, causing the meteor to glow and create a streak of light known as a meteor trail.
What does the color slate look like?
Slate is a dark gray color that resembles the color of natural slate rock. It can have a slightly bluish or greenish tint, and is often described as being a cool, neutral color.
What caused the moon to have dark spots?
What is big dark spot on thee moon? When you look at the moon, you see a large area is dark. Until now no one answer this question. The answer the Google says is this. There are there, because of the shadow that been made by rocks, and this is wrong answer, and why, those dark spot is as big as a country like Iran, no rock can make such big shadow That dark part of moon, what we can see from the earth means only one thing. The surface of the Moon is made in too different Material. 1. The material which can reflect the sun light like a mirror 2. The material which can not reflect the sunlight When you be on moon in the night, you can see the earth , but the earth can not reflect the light, and it is not like moon for earth, it most like Mars, a little brighter because is nearer. by kavoos zijerdi
How are moon and planets are visible even if they are not luminous?
For the same reason that a rock is visible even though the rock is not luminous.Some source of light, such as a flashlight, illuminates the rock, and some of thelight from the flashlight bounces off of the rock in just the right direction to enteryour eye.Similarly, in our neighborhood, some source of light, such as a flashlight, illuminatesthe moon and the planets, and some of the light from the flashlight bounces offof the moon and planets in just the right direction to enter our eyes.The Sun is that source of light.
What are the characteristics of Hornfels?
Hornfels is a type of rock that is metamorphic. They usually have bands and fine grain, and can come in different colors, such as light gray and dark gray.
Can gray rock reflect light?
If an object doesn't reflect light, it will appear perfectly black. So yes, in a sense, a rock does reflect light, since this is what enables you to see it. It is, however, a poor reflector, compared with, say, water, or a mirror. If an object doesn't reflect light, it will appear perfectly black.

What are the colors in a pegmatite rock?
Pegmatite rocks typically contain a variety of minerals, resulting in a range of colors. Common colors found in pegmatites include white, gray, pink, and black. The specific colors present in a pegmatite rock will depend on the mineral composition of that particular rock.
What color is basalt?
The rock basalt can be greenish, blackish, or gray.
What is a dark greenish gray extrusive igneous rock called?
Bogey
Do dark rocks absorb more heat than light rocks?
Dark rocks will absorb more radiant heat than light rocks, for the same reason that any dark object absorbs more heat than an equivalent light object. Light objects appear "light" to us because they reflect more light than objects which appear dark. Dark objects appear dark because they absorb more light and reflect less. However, dark objects will radiate more heat that light objects. Actually, dark rocks do NOT absorb more radiant heat than light rocks. Nor do they radiate more heat than light rocks. Dark rocks DO absorb more LIGHT than light rocks and they then radiate this light at heat. Light rocks reflect the light rather than absorb it and therefore do not radiate as much heat. If you put a light rock and a dark rock next to a HEAT source, the amount of heat absorbed will be related to the makeup of the material rather than to the color.
What is the texture of andesite?
Andesite typically has a fine-grained texture with a mix of various minerals such as plagioclase feldspar and amphibole. It can appear as a dark gray to black rock with speckles of white or light gray minerals.
If a rock has bands of light and dark layers its what?
It could be a sedimentary rock or a foliated metamorphic rock exhibiting alternating bands of light and dark minerals.
What kind of rock is marl?
Marl is a sedimentary rock because the rock is made from dark gray fragments which have been squeezed together.
What does not give off its own light?
People, trees, flagpoles, most animals (although the Japanese have bred "glow in the dark" fish and cats) , planets, moons, and other items that only REFLECT light.
Would you expect a light gray igneous rock to be rich or poor in silica?
I would expect a light gray igneous rock to be rich in silica. Light gray color in igneous rocks is often associated with high silica content, which is typical of felsic or granitic compositions.
What kind of rock would be a dark gray with white dots on it?
The rock you are describing sounds like granite. Granite is a type of igneous rock that is composed of dark gray minerals such as quartz and feldspar, with occasional white dots of minerals like quartz or mica.
