What period is the Age of Imperialism characterized as?
There are various answers that could be given depending on context. I would be willing to bet that your textbook contains that very sentence with the blank filled in. However, some possible answers would be; European conquest, national aggrandizement, rapid economic development, and growth in world trade. There could be others too. The "correct" answer depemds on what your teacher has been emphasizing. Michael Montagne
The old Stone Age is characterized by the first use of stone tools and a nomadic, hunter-gatherer lifestyle. The middle Stone Age is characterized by the beginning of the societal shift from nomadic to agrarian. The new Stone Age, or the Neolithic period is characterized by an agrarian lifestyle and the first domestication of plants and animals.
What is the answer for what characterized the old stone age the middle stone age and the new stone age?
A Dark Age. The word which most accurately characterizes the opposite of "enlighten" is "obscure". The word "enlighten" is characterized by revealing or making known, while the word "obscure" is characterized by hiding or keeping hidden. The phrase "a dark age" is incorrect, because it speaks to a time-period known as the "enlightenment" and there is no time-period associated with the word "enlighten".
Originally defined as a transitional period between the Neolithic Age and the Bronze Age, the Copper Age (or Chalcolithic Age, or Eneolithic Age) is now regarded to be part of the Bronze Age because it is characterized by the use of metals. It was during this time period that early metallurgists found that the addition of tin to copper produced the harder metal, bronze.
