explain how Placer mining works​

Answers

Answer 1

Answer:

Placer mining is done in streams and the gold is found by swirling it in pans. The heavier gold sinks to the bottom and is picked out, sorted by color and kept.

Answer 2

Miners use various techniques to separate the desired minerals from the surrounding materials. Initially, the top layer of soil and vegetation is removed to expose the gravel and sand containing the minerals.

Water is then used to wash and separate the lighter materials, while the heavier minerals settle at the bottom due to their higher density. These concentrated minerals are collected using pans, sluices, or other devices, enabling the extraction of valuable resources through placer mining.

What was accomplished by early farming societies but not by hunter-gatherer societies?

Answers

Hunter gatherers were people who lived by foraging or killing wild animals and collecting fruits or berries for food, while farming societies were those that depended on agricultural practices for survival. Before agriculture was introduced, all human beings were hunter gatherers.

Answer:

Hunter-gatherer societies moved around the land, always searching for sustenance and shelter to feed their tribes. These groups needed to work hard for their survival every day- food was hunted, not planted. Each member had to hunt/gather food. There was no time for resting or thinking of new ideas.

Farming societies did not move around as often, as they invented a way to maintain their tribes for long periods of time without having to be on the move. Consequently, these people had surplusses of food and could afford to feed those who did not hunt/gather food for the rest of the population. This gave way to crafters, artists, and people who had the time to innovate new technologies. Since every tribe member didn't need to work for survival, early farming societies were able to improve living conditions.

what Best illustrates how some Europeans used the headright system to their advantage

Answers

Answer:

The headright system was a land program that was drafted to bring more settlers to the region. This was done by offering acres of land that was called "headright" for people who were willing to come and work on the land.

The leaders of each colony were aware that labor was necessary for economic survival and as a result, they offered land as an incentive for workers that were to be brought in. The masters gave 50 acres of land for each laborer that was brought to work on their land and this helped plantation owners to accumulate wealth.

Great comic artists assume that truth may bear all lights, and thus they seek to accentuate contradictions in social action, not gloss over or transcend them by appeals to extrasocial symbols of divine ends, cosmic purpose, or laws of nature. The moment of transcendence in great comic art is a social moment, born out of the conviction that we are human, even though we try to be gods. The comic community to which artists address themselves is a community of reasoning, loving, joyful, compassionate beings, who are willing to assume the human risks of acting rationally.
