How do geologists use index fossils to determine the age of rock strata?

Geography

love history [14]3 years ago
5 0

The index fossils are fossils that are found in the rock strata of certain geologic period, but they are also fossils that are very common and can be found in numerous places around the globe.

Because they can be found all over the globe, and they are indicative of certain geologic period, the geologists have started to use them as a simple way of determining the age of the rock strata. While this method can not provide the geologists with an accurate year for the formation of the rocks, it is still able to determine the relative age of the rocks. By determining the relative age with such ease by using the index fossils, the geologists are able to immediately make conclusions about the rock strata, have basic information about it, and largely be aware of the processes that formed them and influenced them.

The measures of 2 angles are (2x+2) to the zeroth power and (3x-5) to the zeroth power.
Fantom [35]
First of, what you are referring to zeroth power is not that, actually. It is the symbol for degrees.

If the angles are complementary it means they add up to 90 degrees.

Therefore  (2x+2) + (3x-5) = 90
                2x + 3x +2 -5 = 90
                           5x - 3 = 90
                                   5x = 90+3.
                                    5x = 93.    Divide both sides by 5.
                                       x = 93/5 = 18.6

Therefore:  (2x+2) = (2*18.6+2) = 37.2 + 2 = 39.2  degrees.
                (3x- 5) = (3*18.6-3) = 55.8 - 3 =  52.8  degrees.
So the measure of the smaller anger is 39.2 degrees.
Cheers.

European migration patterns show a dispersion throughout the world. African migration patterns show concentrated numbers migrati
Yuliya22 [10]
History was a driving force behind such migration, since humans tended to move to new territory when they lacked food, shelter, or other resources--meaning that most of the conflicts throughout history have been driven by the same forces that drove migration out of Africa.
