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






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






3. The part of the Earth that we live on






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






5. The act of using radioactive isotopes to date fossils






6. The crystals formed when igneous rocks cool underground






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






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






9. Active boundary where tectonic plates meet






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






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






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






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






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






15. 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.






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






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






18. 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






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






20. The process in which water soaks into the ground






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






22. Degree to which a mnieral can be scratched






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






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






25. 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






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






27. The degree that a mineral reflects light






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






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






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






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






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






33. 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






34. 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






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






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






37. Changes that were made to the DNA and RNA






38. 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






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






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






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






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






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






44. 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






45. A layer of rock that contains fossils






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






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






48. 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.






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






50. The machine that is used to measure earthquakes
