Basic Geo Review Words • The big bang • Edwin hubble • Spiral galaxy • Galaxies • Black dwarf • Supernova • Red giant • Ice Giant • Gas giants • Jovian Planets • Nebula • Terrestrial Planets • Paleozoic Era • Precambrian Eon • Seismologist • Fault • Seismic Waves • Primary waves • Supervolcano • Stratocone Volcano • Convergent • Divergent • Plates • Transform • Subduction zone

3. The big bang • The hypothesis the Universe all starts at one infinitely small point and is now expanding outward in a dramatic explosion

4. Edwin Hubble • Scientist who discovered that the universe is expanding

5. Spiral Galaxy • Galaxy that contains both young and old stars and has large arms

6. Galaxy • A collection of gas, dust, and billions of stars… there are 3 different types.

7. Black Dwarf • A cooled white dwarf that results from the death of a small or medium star

8. Supernova • A super massive star will often ends its life in this large explosion.

9. Red Giant • When a star begins to burn its helium it will swell and cool and turn red, this stage of the star cycle is called the _________ stage

10. Ice Giants • This group of planets(Uranus and Neptune) are made of ice such as methane, ammonia, and water. 

11. Jovian Planets • This group of planets(Jupiter and Saturn) are made most of hydrogen and helium

12. Nebula • A cloud of gas and dust that leads to the formation of stars and planets

13. Mesozoic Era • The middle era of the history of life… this is when dinosaurs evolved some 220 to 65 million years ago.

14. Paleozoic Era • The first era of ancient life. This is when nearly all animals evolved including fish and amphibians. This era ended in the largest extinction.. The Permian extinction.

15. Precambrian Eon • The formation of the earth, oceans, and continents occurred during this section of time… 90% of earth history occurred during this time.

16. Seismologist • A scientist who studies earthquakes

17. Fault • This is the crack that separates plate boundaries

18. Seismic Waves • Earthquake waves

19. Primary Waves • The first waves to be felt in the earthquake

20. Supervolcano • The largest and most rare of volcanoes.. Their calderas can be many miles wide and deep. Yellowstone is an example of this type of volcano.

21. Stratocone Volcano • A type of volcano that has explosive magma… has alternating explosions of lava and magma and examples are Pompeii and Mt St. Helens.

22. Shield Cone • Type of Volcano that is low and flat and has oozing lava.. Example is Hawaii.

23. Convergent Boundary • Plate boundary where plates are coming together

24. Plates Broken sections of earth’s crust

25. Plates Broken sections of earth’s crust

26. Plate Boundary Place where two plates come together

27. Transform Boundary Plate Boundary that involves plates that slide or grind past each other.

28. Subduction Zone Ocean Crust is destroyed at this boundary as it sinks below other crust.

29. Divergent Plate boundary where two plates move apart

30. Terrestrial Planets Small planets, close to the sun that are made of rock and metal

31. Gas Giants The largest planets made of hydrogen and helium… also known as the Jovian Planets
