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. 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






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






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






4. The limited supply of water there is






5. Molten rock






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






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






8. 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.






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






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






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






12. The crystals formed when igneous rocks cool underground






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






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






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






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






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






18. The process in which water soaks into the ground






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






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






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






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






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






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






25. Thew ay a mineral breaks along its crystalline structure






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






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






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






29. 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.






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






31. The part of the Earth that we live on






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






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






34. 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






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






36. The machine that is used to measure earthquakes






37. The process in which plates move and shift






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






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






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






41. The different ways a species can evolve






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






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






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






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






46. The period where the first fish were formed






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






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






49. 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






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