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






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






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






4. A basic type of landform that produces water - forms wind barriers






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






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






7. 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






8. 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






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






10. The crystals formed when igneous rocks cool underground






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






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






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






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






15. 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.






16. A layer of rock that contains fossils






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






18. 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






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






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






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






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






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






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






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






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






27. The limited supply of water there is






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






29. The process in which plates move and shift






30. Changes that were made to the DNA and RNA






31. The act of using radioactive isotopes to date fossils






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






33. The different ways a species can evolve






34. Degree to which a mnieral can be scratched






35. Active boundary where tectonic plates meet






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






37. 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






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






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






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






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






42. 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.






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






44. The machine that is used to measure earthquakes






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






46. Thew ay a mineral breaks along its crystalline structure






47. Water that has infiltrated the ground






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






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






50. 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
