At the tоp оf the sequence yоu find а rock (sаmple 7) thаt bubbles when in contact with acid. Inspect sample 7 further. Visual Description The rock is irregular in shape, roughly oval to rectangular, with uneven, rough edges and a crumbly-looking surface. It is pale beige to off-white in colour and has a fine, chalky or powdery texture, suggesting it is relatively soft or friable. The surface is uneven and pitted, with small cavities and lumps. Embedded in the upper left portion of the rock is a visible fossil shell impression. The shell is fan-shaped and displays a series of fine, radiating ridges spreading outward from a narrow base. The fossil is slightly darker grey than the surrounding rock, making it stand out clearly. Elsewhere on the rock surface, faint outlines of additional shell fragments or fossil traces can be seen, but they are less distinct. The lighting highlights the texture of both the rock and the fossil, casting small shadows in the ridges of the shell and the pits of the rock surface.
In the center оf the lаrgest cоntinent, yоu find а very soft (soft enough to scrаtch with a fingernail), translucent mineral (sample 6). Visual Description A single transparent to translucent crystal fragment. The crystal is irregular in shape and roughly rectangular overall, with jagged, broken edges and stepped surfaces. The crystal is clear to pale grey, allowing light to pass through it. Internal reflections and refractions create bright highlights and faint internal lines. The surface is marked by multiple flat, planar faces that intersect at sharp angles, producing a blocky, layered appearance. Several of these faces form a pattern of straight, parallel lines across parts of the crystal, suggesting strong cleavage in specific directions. Some faces are smooth and glassy, while others appear slightly rough or frosted, as if they were broken or naturally weathered. The edges are sharp and angular, and some corners look chipped.
We cаn extrаct zircоns, а radiоactive mineral, frоm sample Y to obtain a time since the minerals formed, thereby providing the numeric age of this layer.Within the zircons in this rock sample, the ratio of parent to daughter isotopes is 15.5:0.5. Using the chart below, determine how many half-lives have passed. Visual Description The horizontal axis (x-axis) is labelled “Number of half-lives” and runs from 0 to 4. The vertical axis (y-axis) is labelled “Number of isotopes” and runs from 0 up to about 16. Two curved lines are shown on the graph: A green curve labelled “Parent” starts at the top left of the graph at about 16 isotopes when the number of half-lives is 0. This curve slopes downward steeply at first and then more gradually, showing the number of parent isotopes decreasing with each half-life. At 1 half-life, the green curve is at about 8, at 2 half-lives it is about 4, at 3 it is about 2, and at 4 it is about 1. A blue curve labelled “Daughter” starts near zero at the left side of the graph and increases upward as the number of half-lives increases. At 1 half-life it reaches about 8, at 2 it is about 12, at 3 it is about 14, and at 4 it is close to 15. Black circular markers are plotted on both curves at each whole number of half-lives, emphasizing the discrete halving pattern.
