according to composition i.e. mineral grains, fossils, animal/plant matter, chemical composition etc. and grain size (gravel, sand, silt, clay)
for example sandstone is made up of mainly rock fragments or mineral grains (quartz, feldspar, clay) weathered form other rocks and has grains that are 1/16-2mm large.
Because the rocks are formed by using layers of Sediment.
They are called clastic sedimentary rocks.
Metamorphic rocks are classified by foliation or lack there of, not sedimentary rocks. They are classified into Clastic Sedimentary, and Chemical Sedimentary.
No. The rocks you describe are clastic or detrital sedimentary rocks.
Yes all fossils occur in sedimentary rocks or rocks that began as sedimentary rocks.
Because the rocks are formed by using layers of Sediment.
4.rocks are named according to SHAPES and SIZES of sediments.2. Sedimentary rocks form in layers.Theres some!
They are called clastic sedimentary rocks.
All the named rocks are igneous, metamorphic, or sedimentary.

the shape and size of the sediments
Sedimentary rocks.
Clastic sedimentary rocks and Cataclasites (a form of metamorphic rock) are formed from broken rocks.
Rocks that are formed by layers of sediments that are compacted over time are appropriately named sedimentary rocks.
