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.

2. 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






3. Active boundary where tectonic plates meet






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






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






6. The crystals formed when igneous rocks cool underground






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






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






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






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






11. The process in which plates move and shift






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






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






14. 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.






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






17. Changes that were made to the DNA and RNA






18. The degree that a mineral reflects light






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






20. The machine that is used to measure earthquakes






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






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






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






24. 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






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






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






27. Water that has infiltrated the ground






28. The period where the first fish were formed






29. The process in which water soaks into the ground






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






31. 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






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






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






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






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






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






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






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






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






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






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






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






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






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






45. 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






46. Rocks that are formed through major changes like heat like plate movements and they cool down






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






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






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






50. The different ways a species can evolve
