What are index fossils?
Remains of species that existed on Earth for short periods of time
100
What is the law of superposition ?
the law that older rock layers are BELOW younger rock layers
100
What is an example of a Vestigial Structure?
Both whales and snakes have tiny leg like bones that are not visible or used showing that they evolved from animals that had legs
100
What are the 2 types of waves?
mechanical & electomagnetic

400
What is the difference between a phenotype and genotype?
phenotype: physical appearance aka blonde hair
genotype: genes aka BB or Bb
400
What are the 4 factors of natural selection?
Environment
Climate

400
Waves that bounce off a surface are known as ?
reflection
400
I am a vast, interstellar cloud of gas (mostly hydrogen and helium), dust located in space, &act as stellar nurseries where new stars are born.
nebula
500
Why are fossils considered to be so rare?
lucky conditions need to be met- The dead organism must be protected from scavengers, microorganisms and the processes of weathering (usually this means the body is quickly covered by sediments)
500
a break in the geologic record when Rock layers are eroded and/or sediment is not deposited is known as?
uncomformity
500
What is the difference between Analogous & homologous structures?
Analogous:
Different ancestors, Different underlying structures
Homologous:
Same ancestor/Same underlying structures
500
What do waves transfer?
energy from 1 place to another
500
