Question

Which of the following (more than one answer possible) are the most useful radiometric clocks used in geologic studies?

A. Carbon-14 Clock
B. Uranium-Neodymium (U-Nd) Clock
C. Monazite-Baddeleyite (M-B) Clock
D. Potassium-Argon (K-Ar) Clock

Answer 1

The most useful radiometric clocks used in geologic studies are the option b. Uranium-Neodymium (U-Nd) Clock, the Monazite-Baddeleyite (M-B) Clock, and the Potassium-Argon (K-Ar) Clock, which are used to determine the age of rocks.

The correct option is B. Uranium-Neodymium (U-Nd) Clock

Step-by-step explanation:

The most useful radiometric clocks used in geologic studies are the Uranium-Neodymium (U-Nd) Clock, the Monazite-Baddeleyite (M-B) Clock, and the Potassium-Argon (K-Ar) Clock.

The U-Nd Clock is used to determine the age of rocks by measuring the ratio of uranium-238 to lead-206. The M-B Clock is used to date rocks by analyzing the ratio of certain isotopes of monazite and baddeleyite minerals. The K-Ar Clock is used to date rocks by measuring the ratio of potassium-40 to argon-40.

These radiometric clocks are important tools in geology because they provide scientists with valuable information about the age of rocks and the Earth's history.
