sedimentary rock trivia questions
Sedimentary rock commonly forms from compacted and cemented what?
Answer: Sediments
Bonus fact: Layers of particles can harden into rock.
Which sedimentary rock forms largely from sand grains?
Answer: Sandstone
Bonus fact: Sandstone commonly preserves visible grains.
Why are fossils especially common in sedimentary rocks?
Answer: Sediments can bury remains without melting them
Bonus fact: Igneous and high-grade metamorphic processes usually destroy delicate remains.
Marble forms when which sedimentary rock is changed by heat and pressure?
Answer: Limestone
Bonus fact: Metamorphism recrystallizes limestone into marble.
What sedimentary rock is the usual precursor of slate?
Answer: Shale
Bonus fact: Pressure and heat transform shale into slate.
Slate commonly forms from metamorphism of what fine-grained sedimentary rock?
Answer: Shale
Bonus fact: Low-grade metamorphism turns shale into slate.
In an undisturbed sequence of sedimentary rock layers, fossils found in lower layers are generally what relative to fossils above them?
Answer: Older
Bonus fact: This principle of relative dating lets paleontologists order events even when exact numerical ages are unavailable.
Sedimentary rocks form chiefly from what material?
Answer: Deposited products of weathering and erosion
Bonus fact: Sediments can come from pre-existing igneous, metamorphic, or sedimentary rocks.
Badlands are landscapes heavily shaped by what?
Answer: Erosion
Bonus fact: Water and wind carve soft sedimentary rocks into rugged forms.
What type of geologic fold is the Waterpocket Fold?
Answer: Monocline
Bonus fact: The structure produces a step-like flexure in sedimentary rocks.
Which kind of rock commonly forms in layers from sediments?
Answer: Sedimentary rock
Bonus fact: Sedimentary rocks often preserve fossils.
What type of rock commonly surrounds coal seams?
Answer: Sedimentary rock
Bonus fact: Coal forms within sedimentary basins.
