Scientific techniques (Chapter 8)

How do archaeologists and historians gather more information about objects from the past?

• By using artistic techniques

• By using scientific techniques

• By using mathematical techniques

• By using linguistic techniques

What do scientists use to determine the ages of archaeological finds?

• Radiocarbon dating

• Astrology

• Palm reading

• Crystal ball gazing

What are scientific techniques used to assess the likely ages of, such as skulls?

• Radiocarbon dating

• DNA analysis

• Thermoluminescence dating

• Carbon footprint analysis

Why are items found in the lowest strata usually the oldest?

• Due to the layers of rocks being youngest on top and oldest on the bottom.

• Due to the layers of rocks being oldest on top and youngest on the bottom.

• Due to the layers of rocks being randomly distributed.

• Due to the layers of rocks being equally old throughout.

What does stratigraphy involve analysing?

• Different types of rocks

• Different layers of the earth

• Different types of fossils

• Different types of minerals

How can natural disasters and geological events affect the relative dating technique of stratigraphy?

• By altering the sequence of rock layers

• By changing the composition of fossils

• By increasing the accuracy of dating methods

• By decreasing the impact of environmental factors

How is fluorine dating similar to stratigraphy in determining the age of bones?

• Both methods rely on the principle of superposition

• Both methods involve the analysis of chemical elements present in the bones

• Both methods are based on the assumption of constant decay rates

• Both methods use the surrounding geological context to estimate the age

How does the amount of fluorine absorbed by bones relate to the dating technique?

• The more fluorine bones absorb, the older they are

• The less fluorine bones absorb, the older they are

• The color of the bones changes with the amount of fluorine absorbed

• The shape of the bones changes with the amount of fluorine absorbed

How can bones be dated using fluorine dating?

• By absorbing fluorine from the air

• By absorbing fluorine from the water

• By absorbing fluorine from the soil

• By absorbing fluorine from the sun
