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






2. Degree to which a mnieral can be scratched

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






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






6. 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.






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






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






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






10. The crystals formed when igneous rocks cool underground






11. The process in which water soaks into the ground






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






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






14. Changes that were made to the DNA and RNA






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






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






17. 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






18. The part of the Earth that we live on






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






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






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






22. The limited supply of water there is






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






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






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

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






29. The period where the first fish were formed






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






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






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






33. 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






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






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






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






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






38. 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






39. 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

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






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






43. The different ways a species can evolve






44. Water that has infiltrated the ground






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






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






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