1. what are three forms of evidence that wegner used to support his idea of continental drift and which interested him the most?
2. what is the difference between continental drift and plate tectonics, and which is accepted as fact by the scientific community?
3. which layer of the earth makes up the tectonic plates?
4. what is continental crust and ocean crust composed of?
5. think about the types of instruments that a marine scientist or geologist might use to gather evidence to support the theory of plate tectonics. what specific instruments were needed to gather each of the following types of data? (use the "developing the theory" section)
(a) demonstration of the ruggedness and youth of the ocean floor
(b) confirmation of repeated reversals of the earth's magnetic field in the geologic past
(c) emergence of the seafloor-spreading hypothesis and associated recycling of oceanic crust
(d) precise documentation that the world's earthquake and volcanic activity is concentrated along oceanic trenches and submarine mountain ranges
6. how are ocean trenches formed?
7. where is earth's next ocean likely to form?

Gene flow and genetic drift both affect allele frequencies in a population. a high level of gene flow into a population genetic diversity in a population. a high level of gene flow out of a population genetic diversity in a population. genetic drift is the change in allele frequencies due to factors. typically, genetic drift has the biggest impact on populations.
