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






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






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






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






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






6. The crystals formed when igneous rocks cool underground






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






8. The process in which water soaks into the ground






9. Molten rock






10. 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






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






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






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






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






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






16. 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






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






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






19. 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






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






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






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






23. The degree that a mineral reflects light






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






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






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






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






28. Thew ay a mineral breaks along its crystalline structure






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






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






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






32. 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.






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






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






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






36. 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






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






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






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






40. The part of the Earth that we live on






41. 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.






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






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






44. 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






45. 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






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






47. The machine that is used to measure earthquakes






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






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






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