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






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






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






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






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






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






7. 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.






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






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






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






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






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






13. A layer of rock that contains fossils






14. The limited supply of water there is






15. Water that has infiltrated the ground






16. 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






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






18. The process in which plates move and shift






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






20. The process in which water soaks into the ground






21. 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.






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






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






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






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






26. The degree that a mineral reflects light






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






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






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






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






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






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






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






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






35. 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






36. Thew ay a mineral breaks along its crystalline structure






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






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






39. 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






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






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






42. 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






43. The crystals formed when igneous rocks cool underground






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






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






46. 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






47. The part of the Earth that we live on






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






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






50. Molten rock
