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 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.






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






3. 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






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






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






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






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






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






9. 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






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






11. A layer of rock that contains fossils






12. 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






13. All plants and animals have to compete for food - water - space and the fear of being eaten






14. Mountains with sharp peaks and ridges caused when forces inside the earth push up parts of the crust






15. Changes that were made to the DNA and RNA






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






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






18. A fossil that is caused when the skeleton of a dead animal or plant is covered in sand and water and rock and decays over time - leaving a hollow print of the skeleton






19. The machine that is used to measure earthquakes






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






21. Thew ay a mineral breaks along its crystalline structure






22. The part of the Earth that we live on






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






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






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






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






27. Water that has infiltrated the ground






28. 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






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






30. Molten rock






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






32. The layer of the atmosphere that is 50 km above ground and is where the ozone layer is at






33. 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






34. The different ways a species can evolve






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






36. Degree to which a mnieral can be scratched






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






38. A natural disaster caused by pressure deep within the Earth that splits the ground






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






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






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






42. 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.






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






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






45. The period where the first fish were formed






46. The limited supply of water there is






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






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






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






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