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






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






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






4. Molten rock






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






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






7. Active boundary where tectonic plates meet






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






9. 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






10. Degree to which a mnieral can be scratched






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






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






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






14. 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






15. The degree that a mineral reflects light






16. The process in which water soaks into the ground






17. 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






18. Mountains made up by faults - a huge crack in rock where movememnt happens where tectonic plates pull apart






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






20. The crystals formed when igneous rocks cool underground






21. The limited supply of water there is






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






23. 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.






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






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






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






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






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






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






30. Fossil in which an animal's tracks - poop - nests - and bite marks have been preserved






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






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






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






34. The different ways a species can evolve






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






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






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






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






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






40. 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






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 period where the first fish were formed






44. 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






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






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






47. Thew ay a mineral breaks along its crystalline structure






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






49. 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.






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