In Ptolemy's earth-centered model for the
solar system, Venus's phase is never full as viewed from earth because it
always lies between earth and the sun. In reality, as Galileo first recognized,
Venus is full.
<span>Venus is closer to the Sun than Earth. That
is why we cannot see the full Venus. However, Venus is full (whenever it is on the opposite side
of the Sun from Earth). From Earth, Venus's phases range only between new and
crescent.</span>
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.
