What is evolution?
The name of the supercontinent that existed millions of years ago.
What is a Pangaea?
Resources that is naturally replaced quickly like wind and solar.
What are Renewable Resources?
Law that explains why mass stays the same during reactions.
What is Conservation of Mass?
The main source of energy for most ecosystems.
What is the Sun.
Structures that suggests a common ancestor due to similar bones but different functions.
What are Homologous structure?
Law that states older layers are at the bottom; younger at the top.
What is the Law of Superposition?
Energy source that uses the sun's energy to generate electricity.
What is Solar Energy?
This change creates a new substance.
