Q

Who created the 6 stage weathering system

A

17
Q

What are the end stages of bone decoposition

A

Boil meal and soil sihouette

18
Q

What is bone meal

A

19
Q

A rise in 10 degrees C results in what

A

double the chemical and biological reactions

20
Q

After how many metres does soil temperature not change

A

10

21
Q

What happens when no water is present

A

Microbobes and insects don’t have enough moisture to grow in large numbers, thus overall decay rate is decreased

22
Q

What type of soil results in a greater rate of tissue decay

A

Well drained soil

23
Q

Poorly drained soil results in what

A

Slower decay due to waterlogging

24
Q

What are behavioural factors

A

The actions of humans that affect the remains

25
Q

What are the 6 signs of cannibalism

A 
Perimortem breakage
Anvil abrasions
Cut Marks
Burning
Under representation of verterbrae
Pot Polish
26
Q

What is geo taphonomy

A

The study of how someone who buries a body and how the body itself, affects the surrounding environment
