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. A layer of rock that contains fossils






2. Era from 4.6 to 3.8 billion years ago when the Eaerth formed and the planet cooled off






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






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






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






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






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






9. The part of the Earth that we live on






10. 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






11. 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.






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






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






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






15. 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






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






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






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






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






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






21. 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






22. The degree that a mineral reflects light






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






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






25. 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






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






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






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






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






30. 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






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






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






33. The process in which water soaks into the ground






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






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






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






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






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






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






40. The act of using radioactive isotopes to date fossils






41. Changes that were made to the DNA and RNA






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






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






44. The limited supply of water there is






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






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






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






48. 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






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






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