• Dead animals break down.

• Dead animals get pressed into limestone.

• Dead animals settle on the ocean floor.

• Heat and pressure turn limestone into marble.

Look at the picture of the fossils. Based on the evidence shown, what was the most likely environment of these organisms?

• The environment was most likely covered in rock.

• The environment was most likely cold and icy.

• The environment was most likely underwater.

• The environment was most likely dry and hot.

Based on the characteristics observed in a rock sample, how can you determine if it is a sedimentary rock?

• The rock sample has a smooth surface.

• The rock sample has layers of plant and animal fossils.

• The rock sample is shiny and metallic.

• The rock sample is extremely hard and dense.

Look at the "before" and "after" pictures of rock strata. What most likely caused the rock strata to change?

• Movement of Earth's crust pushed on the sediment layers.

• Mineral colors affected the position of the rock layers.

• Wind caused the many different layers of rock strata.

• Sea waves washed over the rocks and caused curvy patterns.
