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






2. Era from 3.8 to 2.5 biillion years ago with the beginning of the geologic record and the formation of the first forms of rocks and bacteria






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






4. Volcano that occurs at divergent plates in underwater plates and creates lava from a mineral called basalt






5. Also known as secondary waves - these are the second - fastest seismic waves and they travel at right angles to the direction of the movement and they produce vertical and horizontal motion






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






7. The highest layer of the atmosphere where the atmosphere is very thin






8. The process in which plates move and shift






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






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






11. The period where the first fish were formed






12. Document produced by the seismograph that shows how long and how intense an earthquake was






13. Remnant of an organism. They are found underground and are at least several thousands years old






14. Time scale that scientists use to break up the historical changes on the Earth into eons - eras - periods - and epochs






15. Active boundary where tectonic plates meet






16. The fourth layer of the atmosphere - which is also the hottest because the air is so thin and the temperature is up to 2000 degrees Celsius






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






18. Degree to which a mnieral can be scratched






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






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






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






22. Era from 4.6 to 3.8 billion years ago when the Eaerth formed and the planet cooled off






23. The limited supply of water there is






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






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






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






27. Pieces of the Earth that make up its crust and float on top of the upper mantle






28. A mixture of gas consisting of oxygen and nitrogen that wraps the earth like a blanket






29. Plate tectonic boundaries where the platse are moving toward each other with one plate eventually going under the other






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






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






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






33. 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.






34. The animal in which a species has evolved from to specialize in their environments






35. Also known as the center of the earth - it is made out of mostly iron






36. Mountains made up by faults - a huge crack in rock where movememnt happens where tectonic plates pull apart






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






38. The mountain ranges taht is a result of when two tectonic plates collided with each other






39. Molten rock






40. 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.






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






42. The machine that is used to measure earthquakes






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






44. Plate tectonic boundaries where plates sllide horizontally pass each other and cause friction






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






46. A harbor wave that occurs when there is a violent disturbance deep below the ocean - like an earthquake - which creates a wave that stores a huge amount of energy






47. 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






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






49. Thew ay a mineral breaks along its crystalline structure






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