Ms. Jones brought this rock to her science class and instructed her students to explain how it was formed, which explanation is
Ahat [919]

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

Explanation:

The only true explanation that perfectly describes the rock is that the leaves were trapped between the layers of sediment millions of years ago causing the imprint.

Leaf imprints are often referred to as trace fossils.

  • Trace fossils points to the different life activities an organism must have been engaged in.
  • When a leaf is trapped in a soft sediment between two layers, the compaction of the sediment can duplicate the form of leaf on beds.
  • This gives a physical overview to the nature of leaf.
  • Such an imprint did not grow, and cannot be attributed to metamorphic processes(option D).
  • Option C is completely wrong
