Ametrine is formed when tiny iron particles locked inside the matrix of the quartz crystals begin to oxidize at different rates. This is usually due to differences in temperature between the two different parts of the stones. As you can imagine, this is a very unique and unusual situation to occur in the natural world!
The desert biome is one that is very hot and dry. They are found at the lower latitudes, between the Tropic of Cancer and the Tropic of Capricorn. Light winds occur often which evaporates any type of moisture that is typically going to develop in them.hat is the only desert biome where it grows. It has a long truck and then wide leaves that are very hard. It can create a sap that is very dark red in color. The aloe plant is also found in the desert biome. Aloe has always been a very important type of natural healing medicine.
Many desert plants, such as the brittlebush, reduce the temperature of their leaves by reflecting sunlight with a thick covering of hairs. Small leaves are another way of reducing water loss. One of the best examples of a small-leaved plant is the cactus, which has reduced its leaves to spikes. Some desert plants also store water. These include succulent plants, such as aloe and barrel cacti, which have stems or leaves containing spongelike cells that absorb water, and plants with underground storage, such as bulbs and rhizomes.
