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. 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






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. 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






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






6. 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.






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






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






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






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






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






12. Active boundary where tectonic plates meet






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






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






15. Thew ay a mineral breaks along its crystalline structure






16. 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






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






18. The machine that is used to measure earthquakes






19. The degree that a mineral reflects light






20. Molten rock






21. Degree to which a mnieral can be scratched






22. The Earth's rivers - lakes - and oceans






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






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






25. A layer of rock that contains fossils






26. 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






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






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






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






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






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






32. The act of using radioactive isotopes to date fossils






33. 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






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






35. 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






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






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






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






39. Changes that were made to the DNA and RNA






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






41. Water that has infiltrated the ground






42. 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






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






44. The limited supply of water there is






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






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






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. The process in which plates move and shift






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






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