Imagine that a geologist finds a sedimentary rock with ripple marks in it.
Brilliant_brown [7]

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.

The chemical equation below summarizes the process of photosynthesis. 6CO2 + 6H2O + energy à 6O2 + C6H12O6 Which is the main sou
kari74 [83]
The main source of energy is the Sun. This is because Photosynthesis is a light dependent reaction. If there was no Sun, there would not be any energy. Soil does not provide energy. ATP is energy but that is usually produced in heterotrophic organisms. Finally it cannot be glucose because that is the product of photosynthesis. Hope this helps and feel free to ask me any more questions you may have!
