Shale is a fine-grained, clastic sedimentary rock, composed of mud that is a mix of flakes of clay minerals and tiny fragments of other minerals, especially quartz and calcite. Shale is characterized by breaks along thin laminae or parallel layering or bedding less than one centimeter in thickness, called fissility

Sandstone is a clastic sedimentary rock composed mainly of sand-sized silicate grains. Sandstones make up about 20 to 25 percent of all sedimentary rocks

Rivers are mostly lowered in the ground about two to three feet below the original ground

the "contour" is most likely the lower parts unlike the "lines" which are higher up

sandstone is on top

shale is below the river

river is above shale but below sandstone

the contour is above sandstone but below lines

Explanation:

so the lines are above every thing and shale is at the bottom because it contains mud and mud gets created from water leaking into the ground and soaking in, also clay gets mixed from mud and coming from beside or below rivers.

Hope this helped out some.
