CSET Science: Geology

Subjects : cset, science, geology
Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. Era from 4.6 to 3.8 billion years ago when the Eaerth formed and the planet cooled off






2. Changes to genetic code that become permanent and can be bad - like sickle cell anemia and cancer






3. Mountains created when hot molten rock pushes up from the earth's mantle






4. The machine that is used to measure earthquakes






5. Soft and plastic layer of the mantle that allows plate tectonics to move






6. A volcano that is formed when ash and cinders are blown out of a single vent






7. Layer of atmosphere that is above the stratosphere where the coldest temperature is reached at minus 90 degrees






8. The mega continent that was once a combination of all the world's continents millions of years ago






9. A giant range of stratovolcanoes that circle the Pacific Ocean






10. Seismic waves that are the slowest but most dangerous because they move on the surface and can knock buildings to the ground






11. Rocks that are made from bits and pieces of other rocks and dead animal and plants that have been pressed together over time






12. The lowest layer of the atmosphere. It is also known as the weather layer since snow - rain - and wind stick to this layer






13. Era between 245 to 65 million years ago and known as the Age of the Reptiles because this was whe nthe dinosaurs existed until a mass extinction. Pangea separates.






14. Organisms - like plants - that take more carbon out of the atmosphere than put into it






15. Earth layer made up of silicon - iron - magnesium - and oxygen and makes up most of the Earth's mass






16. The thick - spongy substance that was created when swamp planst decomposed 300 million years ago. With heat - it becomes coal






17. Rocks made out of trapped magma that takes longer to cool beneath the surface






18. The period when the first amphibians were born. Named after Devon - England where fossils were first discovered






19. The period where the first fish were formed






20. The warming up of the Earth because of certain gases in the atmosphere






21. Areas where oceanic earthquakes can occur when an ocean plate hits a continental plate and eventually goes underneath






22. Volcano that is formed at convergent boundaries of tectonic plates and the subducted plate melts into lava






23. Rocks that form when molten rock cools and hardens either deep underground or on the surface






24. Fossil in which an animal's tracks - poop - nests - and bite marks have been preserved






25. Era from 2.5 billion to 570 million years ago when the continents formed and oxygen began. The first eukaryotic cells appear.






26. Degree to which a mnieral can be scratched






27. Tectonic plate boundaries where plates are moving apart and new crust is being formed by rock pushed up in the mantle






28. The process in which water changes from liquid to gas






29. A fossil caused when the mold of the skeleton of a dead animal is filled with minerals from the bubbling water and the minerals take the shape of the skeleton






30. The Earth's rivers - lakes - and oceans






31. Also known as primary waves - these are the fastest seismic waves and the first to be detected. They compress and expand both liquid and solid rock as they move through it






32. Molten rock






33. A basic type of landform that produces water - forms wind barriers






34. Era from 570 to 245 million years ago with the explosion of animal diversity followed by the wiping out of 99 percent of planetary life thanks to an asteroid. Pangea rises.






35. The form that water returns to earth as - like rain - snow - sleet - and hail






36. The act of using radioactive isotopes to date fossils






37. The look of a mineral when scratched upon a porcelein plate






38. Areas of great heat and activity in the earth's mantle where shield volcanoes can form






39. The degree that a mineral reflects light






40. The limited supply of water there is






41. The study of rock layers and the fossils contained inside of them






42. Fossil in which a part of the organism that has been preserved






43. The different ways a species can evolve






44. The process in which plates move and shift






45. The crystals formed when igneous rocks cool underground






46. Rocks that are formed through major changes like heat like plate movements and they cool down






47. Solid and extremely hot layer of the mantle that protects the core






48. Changes that were made to the DNA and RNA






49. The way that water returns to earth by flowing on the surface into streams - lakes - and rivers






50. Modern era from 65 million years ago to now and known as the Age of the Mammals because of the birth of humans
