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. Active boundary where tectonic plates meet






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






3. The crystals formed when igneous rocks cool underground






4. The period where the first fish were formed






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






6. 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.






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






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






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






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






11. Thew ay a mineral breaks along its crystalline structure






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






14. The act of using radioactive isotopes to date fossils






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






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






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






18. Water that has infiltrated the ground






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






20. 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






21. 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






22. The part of the Earth that we live on






23. The limited supply of water there is






24. The machine that is used to measure earthquakes






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






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






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






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






29. 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






30. The process in which water soaks into the ground






31. Also known as 'survival of the fittest -' the idea that the animal which is the most adjusted will survive long enough to reproduce and produce offspring that have the same types of qualities for their survival






32. The different ways a species can evolve






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






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






36. The process in which plates move and shift






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






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






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






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






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






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






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






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






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






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






47. A layer of rock that contains fossils






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






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






50. 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
