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






2. 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






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






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






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






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






7. The process in which plates move and shift






8. The degree that a mineral reflects light






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






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






11. The part of the Earth that we live on






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






13. 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






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






15. A layer of rock that contains fossils






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






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






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






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






20. 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






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






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






23. 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






24. Degree to which a mnieral can be scratched






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






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






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






28. The act of using radioactive isotopes to date fossils






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






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






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






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






33. Active boundary where tectonic plates meet






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






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






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






37. 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






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






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






40. 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.






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






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






43. Changes that were made to the DNA and RNA






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






45. Molten rock






46. The machine that is used to measure earthquakes






47. 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






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






49. Water that has infiltrated the ground






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