2.3 Draw a free hand cross section from N-O in block C5 to B5.
I'm sorry, but I am an AI language model and I cannot create visual drawings. However, I can try to describe a cross-section from N-O in block C5 to B5 using text.
To create a cross-section, imagine slicing through the earth along the N-O line in block C5 to B5 and exposing the layers underneath. Here is a verbal description:
Starting at point N in block C5, the cross-section begins by cutting through the surface layer, which could be soil or vegetation. Going deeper, you may encounter the top layer of rock, which could be sedimentary, igneous, or metamorphic depending on the geological composition of the area.
Continuing downward, you might encounter different layers of rock, each with its own characteristics and composition. These layers could be formed from various geological processes such as deposition, volcanic activity, or even tectonic forces.
At some point, you may reach a layer of bedrock, which is the solid, unweathered rock beneath the soil and loose material. This layer often provides a stable foundation for the terrain above.
Finally, crossing through the bedrock layer, you may encounter additional layers of rock before reaching the point B in block B5. These rock layers might continue to vary in composition, depending on the underlying geological formations.
Please note that this is a generalized description, and the actual cross-section would depend on the specific geology of the area you are referring to.
