Their gravitational pull towards the planet?
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 impacts of climate change include warming temperatures, changes in precipitation, increases in the frequency or intensity of some extreme weather events, and rising sea levels.
