A dodo egg is a renewable food item that is randomly left behind by a dodo bird. Dodo eggs are large and oval in appearance with a light blue shell with a wavy pattern or darker areas.
As a result, rocks form quickly and mineral crystals are very small. Rhyolite is one type of rock that is formed when lava cools. It contains similar minerals to granite. However, as you can see in Figure 3.21, the mineral crystals are much smaller than the crystals in the granite shown in Figure 3.20.
(Also see Meteorites). Most of the common rock-forming minerals are combinations of the most abundant materials in the Earth, taking into account the differentiation of the Earth into lighter and denser layers early in its history.Also see Meteorites).
