Limestone
Typically an opaque green, greenish-brown, brown or black color.
Anorthosite typically has a coarse-grained texture, with individual mineral grains that are easily visible to the naked eye. It often appears as a mottled combination of white, gray, and black minerals, with a crystalline structure that can exhibit cleavage planes.
Pumice can vary in color depending on its mineral content, but it is commonly light to medium gray or white. It may also have specks of darker colors due to impurities such as iron oxides.
The extrusive form of granite with extremely small crystals and a red, pink, or gray color is called rhyolite. Rhyolite is formed from magma that cools quickly at the Earth's surface, resulting in its fine-grained texture.
Basalt is lava that has cooled rapidly above the surface or underwater, causing it to be fine grained. It is usually gray or black and contains crystals.
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.
Basalt is a dark-colored volcanic rock that is typically fine-grained and often has small cavities filled with minerals. It can appear black, gray, or greenish in color, and is commonly found in areas with volcanic activity.
Granite and Basalt: 1. Granite is formed from magma that cooled slowly, so it has a coarse-grained texture. It may be pink, white-gray or light to moderate yellow. It contains the minerals feldspar, quartz and mica. Its mineral grains are similar in size. Granite is hard to scratch with a fingernail. 2. Basalt is formed from lava that cooled rapidly, so it has a fine-grained texture. Its mineral grains are so tiny that they can be seen only through a microscope. It may be black or dark green. It contains the minerals feldspar and olivine. Like granite, basalt is hard to scratch with a fingernail.
Limestone is a sedimentary rock primarily composed of calcite and aragonite minerals. It often contains fossils or other organic remains. The structure of limestone can vary from fine-grained to coarse-grained, with a range of colors including white, gray, and beige.
Slate is a fine-grained gray, green, or blue metamorphic rock that is easily flattened. The splitting of slate into flat layers illustrates its foliation.

Anorthosite typically has a coarse-grained texture, with individual mineral grains that are easily visible to the naked eye. It often appears as a mottled combination of white, gray, and black minerals, with a crystalline structure that can exhibit cleavage planes.
Andesite rock is formed through the cooling and solidification of magma in the Earth's crust. It typically forms in volcanic settings where magma with intermediate composition (between felsic and mafic) cools relatively slowly, allowing for the formation of fine-grained crystals. This results in a rock with a medium to dark gray color and intermediate mineral composition.
Pumice can vary in color depending on its mineral content, but it is commonly light to medium gray or white. It may also have specks of darker colors due to impurities such as iron oxides.
The extrusive form of granite with extremely small crystals and a red, pink, or gray color is called rhyolite. Rhyolite is formed from magma that cools quickly at the Earth's surface, resulting in its fine-grained texture.
Three types of medium clouds are altocumulus, altostratus, and nimbostratus. Altocumulus clouds are white or gray patches or layers with a lumpy appearance. Altostratus clouds are gray or blue-gray layers covering the sky. Nimbostratus clouds are thick and dark clouds that often bring steady precipitation.
