Biology

Brilliant_brown [7]3 years ago
8 0

Answer:

There are many things that can be read from ripple marks in sedimentary rocks. To start, a geologist looks at: the types (sizes, composition, shapes) of grains in the rock, the height of the “waves”, the distance between peaks (highs) and troughs (lows), whether the rock seems to be lying in its original position, and the internal shapes of the ripples (by looking at the edges of broken pieces). They also seek to determine the age of the rock and information about other rocks lying below and above the specific rock.

svetoff [14.1K]

Answer:

It is recommended to get a flu shot every year as the flu shot only provides protection against the flu for about 6 months. An individual's immune protection from the vaccination declines over time, so they need a new vaccine for optimal protection. In addition, flu viruses evolve and mutate very quickly. New flu vaccines are administered every year to address the rapidly adapting flu virus.

Hope this helps!
