Science
Systematic study of the structure and behavior of the physical and natural world through observation and experiment.
Science
When hundreds of thousands of miles of hydrogen begin to compact together it produces this type of reaction.
Nuclear Fusion
How old is our earth?
4.5 Billion Years old
Tectonic Plates are composed of what type of mechanical earth layer?
Lithosphere
How do shield volcanoes form?
Hotspot (mantle plume) rises and moves through oceanic crust to create relatively nonexplosive volcanoes like Hawaii.
A hypothesis is an explanation for a set of observations but is starting point for further investigations
Hypothesis
What are the next two phases our sun will go through over the next 4 billion years?
Red Giant then White Dwarf
How old is Jupiter and Mars? What theory explains this?
4.5 billion years old, Nebular Theory
Tectonic Plates (lithosphere) glide over the top of a less rigid (plastic) layer called the __________.
Asthenosphere
How do stratovolcanoes form? (think plate tectonics)
The description of an observed phenomenon usually using a mathematical formula. This explains what happens.
What are some examples?
Where are the Elements Carbon, Oxygen, Neon, Silicon, and Iron formed?
The Core of a Supergiant Star!
The first 4 billion years was the age of _________ . The dominating life form was a bacteria called________.
Microbes / Cyanobacteria
What are the three types of plate boundaries?
Convergent, Divergent, and Transform
When a hotspot (mantle plume) is underneath continental crust, the magma does not easily make it through, instead of a sheild volcano, it produces and explosive volcano called a _______
Supervolcano!
a very well tested explanation that brings together many facts and hypotheses. This explains why and how something works.
Scientific Theory
How do elements heavier then Iron (Fe) form?
Supernova
Cyanobacteria changed the atmosphere by pumping ____________ into the atmosphere.
Because of this atmospheric change it caused to earth to___________.
Oxygen, cool down
Subduction
What is the most common way tsunamis are triggered? what type of plate boundary most often triggers tsunamis?
earthquakes, subduction zone (convergent boundary)
List as many scientific theories as you can. 100 points each
Theory of Gravity (General relativity), Germ Theory, Theory of Evolution, Theory of Plate Tectonics, Big Bang Theory, Nebular Theory, Atomic Theory, Quantum theory.
How did heavy elements (heavier then iron) end up within our earth?
Supernova explosions formed a giant nebula, that condensed, eventually forming our solar system
About how many years ago did life begin to diversify, become multicellular and visible within the oceans?
500 million years ago (540 to be more exact)
When factoring all the different types of crust that interact with plate boundaries, how many combinations are there for plate boundaries? (example ocean to ocean divergent)
Convergent (3)
Divergent (2)
Transform (2)
In the last twenty years what were the two most devastating tsunamis? (We talked about both in class)
Japan Tsunami (2011 Tōhoku earthquake and tsunami)
Indian Ocean Tsunami (2004 Indian Ocean earthquake and tsunami )
