CSET Science: Geology

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. 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.






2. Thew ay a mineral breaks along its crystalline structure






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






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






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






6. Degree to which a mnieral can be scratched






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






8. 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






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. The process in which water changes from liquid to gas






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






12. 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






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






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






15. 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






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






17. The process in which plates move and shift






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






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






20. 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






21. The act of using radioactive isotopes to date fossils






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






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






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






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






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






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






28. The machine that is used to measure earthquakes






29. The degree that a mineral reflects light






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






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






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






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






34. A layer of rock that contains fossils






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






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






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






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






39. 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






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






41. 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.






42. Active boundary where tectonic plates meet






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






44. Water that has infiltrated the ground






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






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






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






48. The crystals formed when igneous rocks cool underground






49. The part of the Earth that we live on






50. Molten rock
