Question

12. Which of the following represents a terrestrial depositional environment?: a river, b. beach c. delta d. lagoon e. shallow marine 13. The earlier a mineral crystallizes from Bowen's Reaction Series, the it is at the Earth's surface: a. more stable b. less stable c. larger d. smaller e. none of the above 14. A sequence of sedimentary rocks in which the oldest is on the bottom and the b. Original youngest is on top is an example of the Principle of: a. Sedimentation Horizontality c. Superposition d. Fossil Succession e. Lateral Continuity

Answer 1

Answers:

12. Among these, a. river is the terrestrial depositional environment because among the others, beach, delta and lagoon are coastal or marginal marine depositional environment and shallow marine is marine depositional environment.

13. The earlier a mineral crystallizes from Bowen's Reaction Series, the b. less stable it is at the Earth's surface. This is because, earliest-formed minerals reacts again to form other crystals. That is the reason why this is called a reaction series.

14. A sequence of sedimentary rocks in which the oldest is on the bottom and the youngest is on top is an example of Principle of c. superpositon. This principle forms the major base for stratigraphic dating.
