Continental Drift
1. fossil
2. rock types
3. continents fit like puzzle pieces
When something is magnetic most electrons spin in ______________ (opposite / the same) direction(s)
when something is magnetic, most electrons spin in the same direction
This feature forms at divergent boundaries and results from the build-up of cooling magma on the sea floor. Most prominent in Atlantic ocean
Ridges
Tsunamis are typically caused by energy coming from an underwater _______________
earthquake or volcano
My favorite ocean animal
Otter
Warm magma rises while cool magma sinks due to differences in __________________
density
When magnets stick together, it's because the north pole attracts the _________________ pole
south
This natural disaster is prominent at transform boundaries, and results from the release of frictional stress
earthquakes and/or tsunamis
As tsunamis approach shore, they become
a) taller and faster
b)shorter and faster
c) taller and slower
d) shorter and slower
c) taller and slower
Name one other class I teach at Amherst (not oceanography)
science prep, biology
Name the mechanism by which tectonic plates move
convection currents
How do we know that the polarity of the earth has changed in the past?
Mineral patterns on the sea floor by the ridges
In sea floor spreading, the oldest rock would be
a) farthest away from the ridge
b) closest to the ridge
a) farthest away from the ridge
Name the long term impact that submarine volcanoes have on humans
climate change
What did I write my college thesis paper on?
Women in STEM
Due to continental drift, the Atlantic ocean is actually getting (larger/ smaller) while the Pacific ocean is getting (larger / smaller)
Atlantic- larger
Pacific- smaller
Explain why we believe the Earth is able to generate a magnetic field (one phrase or short sentence)
movement of metals like iron in the liquid outer core
This feature is a result of subduction, where oceanic crust moves underneath continental crust.
volcanoes
The name for an organism that thrives in extreme environments, such as inside hydrothermal vents and submarine volcanoes
extremophile
What subject did I student teach last year?
Earth Science
Which is the largest tectonic plate?
Pacific Plate
Explain why ocean animals may benefit more from magnetoreception than land animals?
The ocean is difficult to navigate because there are less recognizable landmarks, and below a certain depth light is rare
Name a positive impact of submarine volcanic eruptions that mostly occur along the Pacific Plate (Ring of Fire)
Allows for diverse bacteria species to thrive and serves as food for other ocean creatures such as snails
This is a natural magnetic substance that has been found in the cells of animals that use magnetorecpetion for navigation, and our leading explanation as to how magnetoreception works
magnetite
