Question

original horizontality cross-cutting relationship lateral continuity superposition older layers are at the bottom sediment will be deposited in a continuous layer until it slowly thins out or encounters a barrier like a cliff or mountain sedimentary layers are deposited in nearly horizontal layers the geologic feature that cuts across a rock layer is younger than the layer it cuts.

Explanation:

• "Older layers are at the bottom" describes Superposition (layers form bottom-up, older first).
• "Sediment deposited in continuous layer until barrier" matches Lateral Continuity (sediments spread laterally unless interrupted).
• "Sedimentary layers nearly horizontal" is Original Horizontality (sediments settle flat initially).
• "Cutting feature is younger than layers" refers to Cross-Cutting Relationship (disturbances postdate the rocks they cut).

Answer:

• Older layers are at the bottom: Superposition
• Sediment will be deposited in a continuous layer until it slowly thins out or encounters a barrier like a cliff or mountain: Lateral Continuity
• Sedimentary layers are deposited in nearly horizontal layers: Original Horizontality
• The geologic feature that cuts across a rock layer is younger than the layer it cuts: Cross-Cutting Relationship
