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 degree that a mineral reflects light






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






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






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






5. The machine that is used to measure earthquakes






6. 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






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






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






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






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






11. A layer of rock that contains fossils






12. The period where the first fish were formed






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






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






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






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






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






18. 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






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






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






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






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






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






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






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






26. The act of using radioactive isotopes to date fossils






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






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






29. 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.






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






31. The limited supply of water there is






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






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






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






35. 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






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






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






38. Degree to which a mnieral can be scratched






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






40. 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






41. The part of the Earth that we live on






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






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






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






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






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






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






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






49. Changes that were made to the DNA and RNA






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