The Fossil Record
the preserved remains, impression, or trace of an organism that lived in the past, typically embedded in rock and often mineralized over time
Fossil
About how much of the atmosphere is inTroposphere
75%
This is the top of the wave
Crest
Traits that our coded in our DNA
Genetic Traits
In microevolution, the animal changes traits but stays the same species, true or false
true
Over millions of years, the increasing pressure from additional layers of sediment compacts and crystallizes the remains. This turns the sedimentary layers into rock and preserves the fossil within
Crystallization and compaction
Why do Planes Fly In The Stratosphere
Low Turbulence
This is the bottom of the wave
Trough
These occur when an error or change in DNA occurs.
Mutation
True or false, microevolution occurs over millions of years
False
A well-substantiated explanation for a set of observations based on evidence.
Scientific Theory
What Is The Mesosphere's Special Job (Except for that one time with the dinosaurs)
Burn Up Meteors
Waves carry what?
Energy
This mutation, called albinism, causes a lack of melanin in the skin and can prevent an organism from camouflaging and also leads to increased risk of skin cancers and sunburns. good or Bad mutation?
Bad mutation
Microevolution can generally be considered scientific because it meets certain criteria for something to be scientific. What are some of these criteria?
Microevolution can be observed, tested, and it it is repeatable.
This is the easy way of defining the law of superposition
Old rock on bottom, new rock on top
True Or False: There's a lot of gas in the exosphere
False
A wave that moves up and down or side to side
Transverse
In genetics, there are 2 types of traits, dominant and recessive; both of these traits play a role in how our body looks and functions. Which is more likely to show up?
Dominant
During the industrial revolution, a population of moths started to become darker in color with spots of on them (think something like a dalmatian pattern). this allowed them to blend into their surroundings and reproduce. Is this macroevolution.
no, it is microevolution
A car is taken out to the desert, covered in layers and layers of sediment that eventually harden into rock. The car is left for an extended period of time, sufficient enough to fossilize, and is then dug up. Why is the car not considered a fossil?
It is not a living thing
Where Does Most of Our Weather Form
Troposphere
A wave that compresses and expands (squashes and stretches)
Longitudinal
Darwin proposed change over time as the key factor in creating diversity of life even though all life comes from one point of origin. The idea that all life comes from one point of origin is called...

During the industrial revolution, a population of moths started to become darker in color with spots of on them (think something like a dalmatian pattern). this allowed them to blend into their surroundings and reproduce. Why is this microevolution.
It is a change over a short time that changes specific traits, but does not create a new species. the moth is still a moth.
