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?

leaves were trapped between layers of sediment millions of years ago, causing the imprint.
leaves grew from the crevices of the rock from the right balance of light, nutrients, and moisture.
the alternating imprinted design is the result of hot and cold spots when the rock cooled millions of years ago.
a rock under high temperature and pressure pressed against the leaves, turning the leaves to stone.

Hello. You forgot to add the rock photo. The photo is attached below:

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

Explanation:

The stone that Ms. Jones took to the classroom is a stone that shows a leaf fossil from some plant.

As you may already know, fossils are the remains of living beings that have been trapped in rocks for thousands of years, causing a representation of their existence. In the case of the rock carried by Ms. Jones, fossilization occurred when some leaves fell between layers of sediment and were trapped there for thousands of years. This caused the rock to adapt to the shapes of the leaves, causing the imprint.

the answer is; comparing the frequency of collisions with and without the device

this makes the anti-collision system an independent variable and the collisions a dependent variable. if there are fewer collisions with an anti-collision system that without, then it can be stated that the system is a success. essentially, collisions under an anti-collision system are compared with the frequency of collisions by cars with the human drivers.
