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.
Explanation:
What is the day of the leap?
In the four-year cycle, an extra day is added to the calendar. Adjustments to ensure that our calendar is always in sync with the time the earth needs to be in front of the sun. Specifically, the Earth orbit lasts 365 days, 5 hours, 48 minutes and 46 seconds.
This extra 5+ hours is combined over time, so after four years, another day is added - the day of the leap - to our calendar with the sun.
When is the day of the leap?
Hell Day is February 29th. Why February? Because one of the goals of the calendar is based on the solar year, the Easter holiday in the spring. To do this, the calendar is set, so the vernal equinox is always on or near March 21st.
