Geography
1 answer:
allsm [11]3 years ago
7 0
<span>1. The record is incomplete due to burial, erosion, etc.
2. Much, if not all, are metamorphosed
3. There are (for the most part) no fossils to help with depositional environments or age dating
4. Things worked differently in the Precambrian: limestones were formed different, dolomites may have been primary, detrital systems did not behave the same way (lack of meandering fluvial, for example), reduced atmosphere that enabled mobile Iron that made banded-iron formations, some igneous rocks only formed then and do not form today (i.e. kimberlites), etc</span>

What is life like for the Quechua peoples?
PSYCHO15rus [73]
The Quechua people are several different indigenous tribes that live in Peru, Ecuador, Bolivia, Chile, Colombia and Argentina. Because of their location in the mountains, many Quechua people are farmers or use agriculture in their daily lives, growing specific arable foods, as not all produce can grow at such high altitudes. Because of the prominence of llamas and alpacas, weaving is used to make clothes. This is done with cotton or wool and natural dyes, which are then hand-woven by women. Houses are built by men with clay bricks. Quechua people are now moving into cities to find jobs, however this has caused for people to lose their culture and language.
