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. The period where the first fish were formed






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






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






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






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






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






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






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






10. Thew ay a mineral breaks along its crystalline structure






11. The part of the Earth that we live on






12. 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






13. The process in which plates move and shift






14. 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






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






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






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






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






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






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






21. 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






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






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






24. The act of using radioactive isotopes to date fossils






25. 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.






26. 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






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






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






29. The limited supply of water there is






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






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






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






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






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






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






36. A layer of rock that contains fossils






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






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






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






40. Changes that were made to the DNA and RNA






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






42. 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






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






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






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






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






47. The lowest layer of the atmosphere. It is also known as the weather layer since snow - rain - and wind stick to this layer






48. The crystals formed when igneous rocks cool underground






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






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