On the geological maps in question, the cratonic basins that contain thick sequences of sedimentary rocks which overly the Precambrian basement, show the <em><u>youngest rocks</u></em> toward the center of the basin.
Geological maps are tools created and used by scientists to show the arrangement of the geological elements of a specific area. This can include:
- Rock types
- Cracks and faults
- Minerals
- Groundwater
- Ages
and much more, depending on the area and detail of the map created.
On a detailed geo-map, we can understand not only the area we are initially standing on but also where to find geological areas with similar sediment compositions and information on the age of the rocks. This is done due to the way the map stacks the units in terms of age, from the <u>youngest </u>at the <em><u>top </u></em>to the <u>oldest </u>at the <em><u>bottom</u></em>.
Cratonic basins are areas where geological elements are widely distributed and often filled with <u>shallow water </u>as well as <u>sedimentary rocks</u>. The rocks at the center of these basins show the <em><u>youngest</u></em> <em><u>rocks </u></em>at the center due to the previously mentioned <u>aging sequence </u>used by the <u>maps</u>.

Answer:
The following shows 3 (three) differences between oceanic crust and continental crust:
_________________________________________________
Oceanic crust | Continental crust
_________________________________________________
Topographically lower | Topographically higher
_________________________________________________
Composted of basalt | Composed of granite/"granodiorite"
______________________<u> </u>___________________________
Denser | Less dense
