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






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






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. 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






5. The different ways a species can evolve






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






7. The period where the first fish were formed






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






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






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






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






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






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






14. Molten rock






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






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






17. Thew ay a mineral breaks along its crystalline structure






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






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






20. The part of the Earth that we live on






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






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






23. Water that has infiltrated the ground






24. The crystals formed when igneous rocks cool underground






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






26. 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






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






28. 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.






29. 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






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






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






32. Changes that were made to the DNA and RNA






33. The degree that a mineral reflects light






34. Active boundary where tectonic plates meet






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






36. A layer of rock that contains fossils






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






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






39. 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.






40. The mountain ranges taht is a result of when two tectonic plates collided with each other






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






42. The machine that is used to measure earthquakes






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






44. 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






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






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






47. Degree to which a mnieral can be scratched






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






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






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
