Hammer and Anvil Technique
The hammer and anvil technique for removing flakes from a core is perhaps one of the oldest documented methods. It is quite effective for making large flakes for direct use as tools, or for use as blanks from which shaped tools can be made. This technique entails using the core as a hammer, and striking the edge of the core against a large, stationary rock (the anvil) in order to remove a flake.
Bipolar Technique
The bipolar technique is a modification of the hammer and anvil technique. In bipolar flaking, the core is placed on the anvil for support, and then struck with a large heavy hammer. The compression from both ends of the core cause it to shatter into hundreds of flakes, some of which will be large enough, and of the right shape for use as tools. This technique is often found in areas where the only reliable source of workable stone is rounded river cobbles that are extremely hard to work in any other fashion.
<u>Answer:</u>
The Industrialization was the shift from around 1760 to 1840 of new production methods in Europe. This transformation included moving from production methods to machines, new production procedures of chemicals and metal production, rising need for water and steam power, advancement of industrial machinery, as well as the surge of mechanized factory system.
The Industrial Revolution also led to rise in the rate of population growth.The technology went from the use of new materials like steel to energy sources such as motor machines like the "steam engine" and coal which was considered the initial engine of the Industrial Revolution.
The correct answer is A. In the Old Stone Age
Explanation:
The Homo habilis was a species of hominid that preceded the Homo Sapiens (modern humans); this specie originated around 2.3 million years ago and lived in groups. Besides this, the Homo habilis was one of the first species to create tools using stone; indeed, it was found Homo habilis selected and cut stones to use these to cut meat or even plants. This important technological advance occurred during the Old Stone Age or Early Stone Age, which refers to the first period in which hominids created stones that occurred between 2.6 million years ago and 10,000 years ago. Thus, the Homo habilis first began using tools in the Old Stone Age.
