Test your basic knowledge |

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






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






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






4. A layer of rock that contains fossils






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






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






7. 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






8. The part of the Earth that we live on






9. The different ways a species can evolve






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






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






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






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






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






15. Active boundary where tectonic plates meet






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






17. 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






18. 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






19. 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






20. The process in which plates move and shift






21. The crystals formed when igneous rocks cool underground






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






23. 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.






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






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






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






27. A gas that absorbs harmful UV rays and protects us from too much radiation






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






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






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






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






32. 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






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






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






35. The Earth's only liquid layer that is extremely hot and made out of iron and nickel






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






37. The process in which water soaks into the ground






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






39. Degree to which a mnieral can be scratched






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






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






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






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






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






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






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






47. The machine that is used to measure earthquakes






48. The limited supply of water there is






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






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