Answer:

law of original horizontality, law of superposition, law of original lateral continuity and law of cross-cutting relationships.

Explanation:

Before we know the principles of Stratigraphy, we need to understand what it is. To do this, let's first look at the origin of the word statigraphy: from Latin stratum means layer and from Greek graphia means field of study. From this we can understand that stratigraphy is the study of layers. Therefore, we define stratigraphy as the study of the sedimentary rock layers and it seeks to determine the processes and events that formed them.

Now that we know what Stratigraphy is, let's know its principles:

  • Law of superposition: In any succession of strata of rock (which has not been deformed), the oldest stratum is positioned lower, with the successively younger strata being positioned higher. This principle allows us to identify the order of formation of the strata, which is the basis of all historical interpretation of stratigraphic rocks.
  • law of original horizontality: Sedimentary deposits usually accumulate in horizontal layers under the influence of gravity.
  • law of original lateral continuity: Sedimentary layers are continuous, extending to the margins of the deposition basin, or tapering laterally
  • law of cross-cutting relationships: states that an intrusive or faulty rock that cuts a sequence of rocks is younger than the rocks it cuts.

a species of reptile lives on several different islands some of the islands contain a certain species of mammal while some do no
iren [92.7K]

Answer:

<em>23%</em>

Explanation:

The maximum number of individuals of a population that a particular ecosystem can hold is known as the carrying capacity of that particular population.

As the reptiles living in the ecosystems, without the mammal species, had to compete less, hence there carrying capacity was more in such areas.

There s a difference of 23% in the carrying capacity fir reptiles in the areas where the particular species of mammals were present.

240+ 150= 390

240-150= 90

90 divided by 390 and then multiplied by 100 gives 23%.
