Soil is formed by the process of weathering. The soil is the uppermost layer of the surface of Earth. The first formed soil contains pieces of rocks and other particles.
Soil is the uppermost thin layer of material covering the earth's surface. It is formed from the weathering of large rocks. It is made up of mineral particles, organic materials, air, water and living organisms like bacteria.
The lichens are the pioneer species which invade the bare rocks and convert them into soil. They secrete acids which dissolve the rocks. This helps in their weathering and formation of soil. Mosses grow on the rocks along with the lichens to form a mat over the substratum.
Under the action of factors like heat, cold, rain, wind, and other atmospheric factors, the rock breaks down physically into the parent material of the soil.

No, the Aztecs did not have llamas. Llamas are native to South America and were primarily domesticated by the indigenous peoples of the Andean region, such as the Incas. The Aztecs, on the other hand, were an ancient civilization that inhabited central Mexico from the 14th to the 16th centuries. They did not have access to llamas in their region.
The Aztecs, however, did have other domesticated animals that were important for their society and economy. These included turkeys, dogs, and ducks. Turkeys were particularly valued for their feathers, meat, and symbolic significance in Aztec rituals and ceremonies.
While llamas were not present in Aztec culture, they did have a vast agricultural system that included crops like maize, beans, and squash. These crops formed the foundation of their diet and economy. Additionally, the Aztecs had a complex trade network that allowed them to obtain various goods from different regions, including exotic animals and products.
In summary, the Aztecs did not have llamas. Llamas are native to South America, while the Aztecs resided in central Mexico. They did, however, have other domesticated animals like turkeys and had a sophisticated agricultural and trade system.
