Fossil trees were discovered in a sedimentary rock layer. In the rock layer below are fossils of clams, similar to clams that are currently found on the shores of the Gulf of Mexico. Based on this evidence, we could conclude that the area where the fossils were discovered had what sequence of climates in the past?

• Beach, followed by a forest

• Rocky and dry, then very moist

• Forest, and later a mountain

• Very cold area, then much warmer

Fossil ferns, like the ferns found in modern swamps, were discovered in a layer of rock. In a rock layer below were found the fossils of cactus, like those that live in hot, arid deserts today. Based on this evidence, we could conclude that the area where the fossils were discovered had what sequence of climates in the past?

• Forest, followed by deep ocean

• Cold climate that got warmer over time

• Rushing river, then a dark cave

• Very dry and then, much more damp
