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. Degree to which a mnieral can be scratched






2. The period where the first fish were formed






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






4. The part of the Earth that we live on






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






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






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






8. Thew ay a mineral breaks along its crystalline structure






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






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






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






12. 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






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






14. The crystals formed when igneous rocks cool underground






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






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






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






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






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






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






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






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






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






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






26. 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.






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






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






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






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






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






32. A layer of rock that contains fossils






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






34. 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






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






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






37. 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






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






39. The different ways a species can evolve






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






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






42. 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.






43. Active boundary where tectonic plates meet






44. Water that has infiltrated the ground






45. The process in which water soaks into the ground






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






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






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






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






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