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






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






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






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






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






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






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






8. 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






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






10. 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.






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






12. The different ways a species can evolve






13. Changes that were made to the DNA and RNA






14. Degree to which a mnieral can be scratched






15. The process in which water soaks into the ground






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






17. 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.






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






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






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






21. 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






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






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






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






25. The crystals formed when igneous rocks cool underground






26. A layer of rock that contains fossils






27. Water that has infiltrated the ground






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






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






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






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






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






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






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






35. 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






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






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






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






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






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






41. The act of using radioactive isotopes to date fossils






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






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






44. The degree that a mineral reflects light






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






46. 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






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






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






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






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