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






2. Degree to which a mnieral can be scratched






3. The part of the Earth that we live on






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






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






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






7. The process in which water soaks into the ground






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






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






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






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






12. 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






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






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






15. 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






16. The act of using radioactive isotopes to date fossils






17. The crystals formed when igneous rocks cool underground






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






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






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






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






23. The limited supply of water there is






24. 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






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






26. The process in which plates move and shift






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






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






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






30. Molten rock






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






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






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






34. 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






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






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






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






38. The machine that is used to measure earthquakes






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






40. The degree that a mineral reflects light






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






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






43. 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.






44. Water that has infiltrated the ground






45. The mountain ranges taht is a result of when two tectonic plates collided with each other






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






47. 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






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






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






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