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






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






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






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






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






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






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






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






9. The degree that a mineral reflects light






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






11. Active boundary where tectonic plates meet






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. 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






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






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






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






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






18. The process in which plates move and shift






19. The machine that is used to measure earthquakes






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






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






22. Changes that were made to the DNA and RNA






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






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






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






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






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






28. Thew ay a mineral breaks along its crystalline structure






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






30. 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






31. The period where the first fish were formed






32. The crystals formed when igneous rocks cool underground






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






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






35. 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






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






37. 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.






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






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






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






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






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






44. The process in which water soaks into the ground






45. 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.






46. The different ways a species can evolve






47. Molten rock






48. The act of using radioactive isotopes to date fossils






49. A layer of rock that contains fossils






50. 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
