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






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






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






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






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






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






7. 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






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






9. Changes that were made to the DNA and RNA






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






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






12. The process in which water soaks into the ground






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






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






15. A layer of rock that contains fossils






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






17. 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.






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






19. Active boundary where tectonic plates meet






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






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






22. Degree to which a mnieral can be scratched






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






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






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






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






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






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






29. 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






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






31. 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.






32. The look of a mineral when scratched upon a porcelein plate






33. The limited supply of water there is






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






35. The degree that a mineral reflects light






36. Rocks that form when molten rock cools and hardens either deep underground or on the surface






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






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






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






40. The machine that is used to measure earthquakes






41. The period where the first fish were formed






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






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






44. The act of using radioactive isotopes to date fossils






45. 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






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






47. 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






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






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






50. 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
