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






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






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






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






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






6. 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






7. The degree that a mineral reflects light






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






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






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






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






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






13. 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






14. 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






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






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






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






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






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






21. Degree to which a mnieral can be scratched






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






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






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






25. 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






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






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






28. Changes that were made to the DNA and RNA






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






30. 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.






31. The limited supply of water there is






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






33. A layer of rock that contains fossils






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






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






36. 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






37. The process in which plates move and shift






38. 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






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






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






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






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






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






44. Active boundary where tectonic plates meet






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






46. Water that has infiltrated the ground






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






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






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






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