What is the Difference between experimental archaeology and ethnoarchaeology?

Experimental Archaeology is performed by archaeologists or other scientists. the questions asked most commonly involve technology, such as how would one produce a specific tool or checking what could a tool be used for by scientific means, such as wear-marks.

Ethnoarchaelogy involves watching pre-industrial people and their use of tools. the two methods can be complementary, for example, if a pre-industrial tribe of people uses a tool that resembles something found in the archaeological record, by watching how the tribes people use the tool, the archaeologist can get an idea for how the ancient tool was used and can attempt to verify this idea by scientific examination.
