True or False: Sedimentary rocks are crystalline in nature
False
what are the last two steps of the formation of sedimentary rocks called
Lithification
process of evaporation in sedimentary rocks?
when water gets evaporated than it leaves some particles behind which forms the rock.
Name two types of mechanically formed rocks ?
Sandstone and shake

true
Name the 5 basic steps in the formation of sedimentary rocks. Double Jeopardy
EROSION
WEATHERING
DISSOLUTION
PRECIPITATION
LITHFICATION
What happens during compaction? Double Jeopardy.
the layers of sediment build up and the pressure on the lower layers increases than the layers are squeezed together forming sedimentary rocks.
How is Coal formed? Phone Call.
Coal is a sedimentary rock formed over millions of years from compressed plants.
How are Riverine rocks formed? Double Jeopardy.
They are naturally shaped by erosion or formed by the alluvial deposits brought by flowing water of streams.
Why do sedimentary rocks have many layers
They have many layers as they are formed due to the deposition of sediments
