If there was more than one planet on each orbit, eventually they would collide with each other.
The sun appears to cross the plane of Earth's equator
when it reaches either one of the "equinox" points in the sky.
At those times, the lengths of day and night are nominally equal
everywhere (except at the poles), and the occasions are marked
as the beginning of Spring and Autumn.
A Tweet From D. Trump Would Be Primary
The Balkan nations are currently capitalist, not communist, so the first statement is correct. Further, they do have internal conflict, for example between the Bosniak and Serbian population in Bosnia. They also attract foreign investment.

Answer:
The answer is Option C: Index fossils.
Explanation:
Index fossils are used to identify geologic periods or faunal stages in rock layers. These fossils must have a wide geographic distribution and manifest obvious evolutionary trends to help geologists and others who need this geological data to better understand the time scale and to pinpoint a time period. For example, ammonites were common during the Mesozoic Era, but they were extinct by the Cretaceous period. Geologists would use ammonites to help determine this time frame if present.
