How does the altitude of the Sun at noon on the same day in the Northern Hemisphere’s summer compare for two observers at lati-

tudes 12° north and 54° north, respectively? a. It is the same for both observers because they are in the same hemisphere, experiencing summer. b. It cannot be determined without knowing their longitudes. c. It is 42° higher for the observer at 12° north because of the differ- ence in latitude.

Answer:

It is 42° higher for the observer at 12° north because of the differ- ence in latitude.

Explanation:

The sun's altitude can be given by the following formula:

S = 90 - L + D

In which S is the sun's altitude, L is the latitude of the place and D is the declination of the sun.

Since the comparasion occurs at the same day, the value of D will be the same for both cases, so it can be disconsidered in our calculation.

First observer

L = 12

S = 90 - L + D = 90 - L = 90 - 12 = 78

Second observer:

L = 54

S = 90 - L + D = 90 - L = 90 - 54 = 36

The correct answer is:

It is 42° higher for the observer at 12° north because of the differ- ence in latitude.

How do geologists use index fossils to determine the age of rock strata?
love history [14]

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.
