- True
- False
Frage 15
Frage
What process forms sedimentary rock when mineral grains are stuck together into the rock?
Antworten
-
Liquifaction
-
Bedding
-
Cementation
Frage 16
Frage
What is type one cementation?
Antworten
-
A new mineral grows between grains as dissolved mineral precipitate out of groundwater.
-
Grains grow in size because the same minerals precipitate from groundwater and crystallize around them.
Frage 17
Frage
What is type 2 cementation?
Antworten
-
Grains grow in size because the same minerals precipitate from groundwater and crystallize around them.
-
A new mineral grows between grains as dissolved mineral precipitate out of groundwater.
