What is it called when water that contains a lot of minerals enters the pores of an object. Over time, the water evaporates leaving behind mineral crystals in the shape of the object.

• A petrified fossil
• A cast fossil
• A mold fossil
• A trace fossil

What is a trail, track or burrow left behind by an animal that later fossilized?

• A trace fossil
• A carbon film
• A petrified fossil
• An extrusion

• a trace fossil
• a cast fossil
• an index fossil

What is the Law of Superposition?

• The oldest rocks are at the top of the sequence and the youngest are at the bottom
• The rocks at the bottom of the sequence must be super strong to support those above
• The youngest rocks are at the top of the sequence and the oldest are at the bottom
• The forcing of molten rock into an earlier formation

What is relative age?

• The geologic age of a fossil, rock or geologic feature defined relative to other fossils, rocks or features
• The geologic age of a fossil based on when the relatives of that fossil died
• The geologic age of a fossil, or geologic event expressed in units of time
• How old your mom is
