|
Definition
| Relative dating (guessing) and absolute dating (testing) |
|
|
Term
| NAME THE FOUR MAIN TYPES OF RELATIVE DATING TECHNIQUES AND A BRIEF EXPLANATION OF EACH. |
|
Definition
| Stratigraphy (‘layers’), typology (look at forms/shapes and order), seriation (order objects appear), environmental (climate changes) |
|
|
Term
| NAME THE SIX MAIN TYPES OF ABSOLUTE DATING TECHNIQUES . |
|
Definition
| Historical (records), varves and tephra (varves=deposits near lakes, tephra=volcanic ash: layers), dendrochronology (tree rings), radiocarbon, optically stimulated luminescence, archeomagnetic |

|
Definition
| Sets a date at which or after which an event must have occurred |
|
|
Term
| WHAT IS TERMINUS ANTI QUEM? |
|
Definition
| Sets a date which all earlier events must predate |

Term
| WHAT IS THERMOREMANENT MAGNETISM (TRM)? |
|
Definition
| Any heated rock that cools can record the direction of earth’s magnetic field at that time |
|
|
Term
| WHAT ARE THE THREE MOST IMPORTANT MATERIALS SUITABLE FOR MAGNETIC DATING? |
|
Definition
| Volcanic, sediments and baked earth/clay |
|
|
Term
| WHAT ARE THE TWO DATE RANGES FOR MAGNETIC DATING? |
|
Definition
| Directional and intensity (present – 8000BP) and polarity (80k+) |
|
|
Term
| TRUE OR FALSE, MAGNETIC NORTH AND TRUE (GEOGRAPHIC) NORTH ARE ALWAYS THE SAME? |
|
Definition
| False, magnetic north varies over time (up to 10 degrees per century) |
|
|
Term
| TRUE OR FALSE, THE DIRECTION OF MAGNETIC NORTH CAN REPEAT ITSELF AND THE RATE CHANGE IN DIRECTION CAN VARY. |
