🧬 EVOLUTIONARY HISTORY
Species inherit their body structures from earlier populations.
What is that species inherit body structures from ancestor populations?
A population can be described by the traits present and by this.
What is the number of individuals with each trait?
Earth’s outer layer is made of this material.
What is hard, solid rock?
When something gets hotter, its molecules do this.
What is move faster?
Rocks form in different ways, which causes them to become this.
What are different types of rocks?
When two species share body structures, this suggests they descended from the same earlier population.
What is evidence of a common ancestor?
Over generations, adaptive traits become more common because individuals with those traits are more likely to do this.
What is survive and reproduce?
Earth’s outer layer is divided into sections called this.
What are plates?
Temperature measures this about molecules.
What is the average kinetic energy?
When sediment is compacted and cemented together, this type of rock forms.
What is sedimentary rock?
When populations are separated into different environments, natural selection causes this to happen to their body structures.
What is different changes or adaptations occur in each population?
Whether a trait is adaptive depends on this factor.
What is the environment?
At divergent boundaries, this happens as rock rises and hardens.
What is new crust forms?
When two objects touch, energy transfers from molecules moving faster to molecules moving this way.
What is slower?
This type of rock forms when magma cools and hardens.
What is igneous rock?
When environments stay mostly the same over time, body structures tend to do this.
What is remain stable?
Changes to genes that can result in new traits are called this.
What are mutations?
At convergent boundaries, this process occurs when one plate moves under another.
What is subduction?
Energy cannot be created or destroyed; as it transfers, it does this in different parts of a system.
What is increases in one part and decreases in another?
When matter is transformed by energy in the rock cycle, this remains the same.
What is the matter itself?
Among three species, the two that separated most recently are considered this.
What is most closely related?
A new trait will only increase in a population if it is this.
What is adaptive?
Earth’s plates move at a rate that is too slow for humans to do this.
What is experience or feel directly?
Energy transfers between objects until they reach this stable state.
What is equilibrium?
Because of plate motion, any type of rock can eventually become this.
What is any other type of rock?
