Question

select the correct answer. ms. jones brought this rock to her science class and instructed her students to explain how it was formed. which explanation is a true description of the rock? a. leaves were trapped between layers of sediment millions of years ago, causing the imprint. b. leaves grew from the crevices of the rock from the right balance of light, nutrients, and moisture. c. the alternating imprinted design is the result of hot and cold spots when the rock cooled millions of years ago. d. a rock under high temperature and pressure pressed against the leaves, turning the leaves to stone.

Explanation:

Fossil imprints like the one shown are formed when organic material such as leaves is trapped between layers of sediment over long - periods of time. As the sediment compresses and turns into rock, the organic material decays, leaving behind an imprint. Option A correctly describes this process of fossil - formation. Options B, C, and D have incorrect descriptions of the process.

Answer:

A. Leaves were trapped between layers of sediment millions of years ago, causing the imprint.
