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 4.6 to 3.8 billion years ago when the Eaerth formed and the planet cooled off






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






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






4. Changes that were made to the DNA and RNA






5. The degree that a mineral reflects light






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






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






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






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






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






11. The machine that is used to measure earthquakes






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






13. Degree to which a mnieral can be scratched






14. The limited supply of water there is






15. 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






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






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






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






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






20. Active boundary where tectonic plates meet






21. The crystals formed when igneous rocks cool underground






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






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






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






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






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






27. Molten rock






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






29. Fossil in which an animal's tracks - poop - nests - and bite marks have been preserved






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






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






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






33. The process in which water soaks into the ground






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






35. 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.






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






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






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






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






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






41. 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






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






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






44. 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






45. The period where the first fish were formed






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






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






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






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






50. 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
