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






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






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






4. The crystals formed when igneous rocks cool underground






5. The different ways a species can evolve






6. 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.






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






8. 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






9. 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






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






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






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






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






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






15. Water that has infiltrated the ground






16. 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






17. Active boundary where tectonic plates meet






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






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






20. Molten rock






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






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






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






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






25. 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.






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






27. 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






28. Thew ay a mineral breaks along its crystalline structure






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






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






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






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






33. 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






34. 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






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






36. The process in which plates move and shift






37. The process in which water soaks into the ground






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






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






40. Degree to which a mnieral can be scratched






41. The degree that a mineral reflects light






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






43. The act of using radioactive isotopes to date fossils






44. A layer of rock that contains fossils






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






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






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






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






49. Changes that were made to the DNA and RNA






50. The part of the Earth that we live on
