Question 1

Biogenic reef

Answer 1

When the reef is created by living organisms

Question 2

Bioherm

Answer 2

1) Hermotiphic
2) Limestone buildup caused by biological activity

Question 3

What are bioherm and calcareous sediments affected by? (3)

Answer 3

1) Rate by which they are entering the environment from biogenic or terrigenous source
2) Bafflers
3) Binders

Question 4

Bafflers

Answer 4

Things that create an area of slower moving water so sediments settle out (ex: eelgrass, coral reefs = ultimate bafflers)

Question 5

Binders

Answer 5

Things that actually settle on sediment and bind it (Ex: algae, bacteria)
