Why do you think raindrop impressions are more likely to be preserved in fine- grained sedimentary rock rather than coarse- grained sedimentary rocks?
Vary fine sediments, such as mud, will crater when struck by raindrops. If the viscosity is not decreased by too much rainfall or influx of water, the raindrop impressions will be preserved when the mud dries. If subsequent sedimentation over the dried mud is rapid, the dried mud will not have time enough to dissolve by the influx of additional moisture. Thus the imprints may survive eventual lithification into rock. Coarser sediments would involve larger mineral and rock particle sizes and more pore space than finer, less porous sediments. The larger particles, and greater porosity would not be conducive to the creation of raindrop impressions or their preservation, as the drop would not cause a cratering of the impacted sediment, but rather pass around and through it.
Is shale igneous sedimentary or metamorphic?
Shale is a sedimentary rock formed from the compaction of fine-grained sediment such as mud or clay.
Is breccia a coarse-grainedmedium-grainedor fine-grained?
Breccia is a coarse-grained sedimentary rock that is composed of large, angular fragments.
What are three types of sedimentary rock texture?
Three types of sedimentary rock texture are clastic (made of broken fragments), crystalline (formed from the precipitation of minerals), and biogenic (composed of organic material such as shells or plant remains).
What is an example of a medium-grained clastic sedimentary rock?
Sandstone is an example of a medium-grained clastic sedimentary rock. It is composed of sand-sized particles that are typically visible to the naked eye, giving it a medium-grained texture. Sandstone forms from the accumulation and cementation of sand grains.

What is a coarse-grained sedimentary rock in which large rounded sediments can be seen?
conglomerate
Is mudstone a Metamorphic rock?
No, mudstone is a type of sedimentary rock formed from the compression and cementation of fine-grained mud and silt particles. Metamorphic rocks are formed from the alteration of pre-existing rocks due to high pressure, temperature, or chemical processes.
What is A fine grained sedimentary rock that forms slate when under extreme heat?
Shale.
