If a flat lying sedimentary rock layer ends abruptly, which principle tells that it has likely been deformed
Furkat [3]

The principle that tells that the flat lying sedimentary rock layer, which ends abruptly, has likely been deformed is Original horizontality principle. Option D.

<h3>What are the stratigraphic principles?</h3>

  • Superposition principle

Sedimentary rocks have been chronologically accumulating for years, reflecting the geological formation known as superposition.

According to this sedimentary deposition, we can distinguish the older rocks located in the deepest areas from the younger rocks in more superficial layers.

  • Lateral continuity principle

When talking about lateral continuity, we refer to different strata -sedimental layers- horizontally deposited that have a limited continuity.

This is, when looking laterally, each layer is not infinite. They tend to smoothly end.

These layers get thinner as they get farther from the source until they disappear.

When looking at plane rocky strata, we can notice they have not suffered from any perturbation and keep the original horizontality.

As they disappear, they tend to

• Mint

• Harrow

• Interdigitate

• be truncated

  • Original horizontality principle

This principle refers to the fact that strata extend originally in all horizontal directions. Sedimental layers are horizontally deposited.

However, it may occur that the currently observed strata arrangement is not the same as it used to be.

This is due to tectonic changes that have modified the original positions. Thus, layers can appear

  • folded,
  • slanted, or
  • inverted⇒ leaving  the most ancient layers in the upper positions.

The principle that tells that the flat lying sedimentary rock layer, which ends abruptly, has likely been deformed is Original horizontality principle. Option D.

identify which type of ecological pyramid best traces the flow of matter through an ecosystem. Explain your answer.
Sergeeva-Olga [200]
The best pyramid for this is the biomass pyramid. That is because they show how much ecological material can be found at each trophic level, which then can be used to model how the matter flows through the ecosystem that is being analyzed.

The various geologic settings in which rocks can melt, metamorphose, or become sediment are ultimately generated by Choose one:
NNADVOKAT [17]

Answer:

Plate Tetonics

Explanation:

Plate interactions, as a result of plate tectonics, ultimately generate the various geologic settings where Earth materials can melt, metamorphose, and/or weather to become sediments.
