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






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






3. 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






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






5. The act of using radioactive isotopes to date fossils






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






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






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






9. 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






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






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






12. Molten rock






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






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






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






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






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






18. 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






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






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






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






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






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






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






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






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






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






28. The part of the Earth that we live on






29. The machine that is used to measure earthquakes






30. A layer of rock that contains fossils






31. 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






32. 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.






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






35. The degree that a mineral reflects light






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






37. The limited supply of water there is






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






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






40. The crystals formed when igneous rocks cool underground






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






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






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






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






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






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






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






48. Active boundary where tectonic plates meet






49. Plate tectonic boundaries where the platse are moving toward each other with one plate eventually going under the other






50. Water that has infiltrated the ground
