Pregunta 14
Pregunta

Respuesta
- True
- False
Pregunta 15
Pregunta
What process forms sedimentary rock when mineral grains are stuck together into the rock?
Respuesta
-
Liquifaction
-
Bedding
-
Cementation
Pregunta 16
Pregunta
What is type one cementation?
Respuesta
-
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.
Pregunta 17
Pregunta
What is type 2 cementation?
Respuesta
-
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.

Respuesta
-
Lithification
-
Bedding
-
