Q: The Bssyz2 horizon of the Duke soil series (Fine, mixed

The Bssyz2 horizon of the Duke soil series (Fine, mixed, active, thermic Sodic Haplusterts; Harmon County, OK; Pedon ID: S2003OK-057-006 DUKE) is 47% smectite clay. The soil displays a “slight efferve...

Q: The Earth’s crust contains thorium and uranium although no stable isotope exists

The Earth’s crust contains thorium and uranium although no stable isotope exists for either element. Explain why these unstable elements are present in the Earth’s crust.
