beginnings in archaeology Flashcards
What is a primary source?
primary sources were created during the time of what is being investigated.
What is a secondary source?
A secondary source is a source created after the time that is being investigated.
four ways archaeological sites are located?
natural forces, ancient writings, aerial photographs and human activity.
What is excavation?
to dig up.
What is a strata?
Strata is a layer of Earth from an excavation site, usually the top layer is the most recent and it descends from there.
Three methods of excavation?
box-grid system - the site is divided into a grid of ‘boxes’ usually used on sites known to have been inhabited. The boxes are separated with walls of Earth.
Keyhole excavation - usually involves digging trenches at specific points of the site. (this system is less costly).
Open Area excavation - this involves digging up a large horizontal area one layer at a time.
What is relative dating?
Relative dating establishes whether an artefact is older or younger than other artefacts found. One way this is deciphered is with strata: in which different objects are found and it is assumed the deeper in earth the older the object, but this technique is unreliable because natural forces may force land to move along with objects in the strata’s.
Absolute dating?
Absolute dating is done easily if the date is marked on the objects (such as coins and inscriptions) but analysing exact date involves involves analysing atoms of artefact.
Radio-carbon dating?
Measures how much carbon-14 is left in an organic artefact to measure the age of it.
Dendrochronology?
Is used to date wood by examining rings formed: each year trees grow an extra layer this adds a ring to the trunk so from this the age of wood can be discovered.
agriculture
growing crops and raising domesticated animals.
How did humans populate Earth?
Modern Humans first originated in Africa (evolving from primates), where they continued to evolve and spread across the globe to colonise new land and adapt.
