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






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






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






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






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






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






8. Molten rock






9. The degree that a mineral reflects light






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






11. Degree to which a mnieral can be scratched






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






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






14. Changes that were made to the DNA and RNA






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






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






17. The limited supply of water there is






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






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






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






22. The act of using radioactive isotopes to date fossils






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






24. Active boundary where tectonic plates meet






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






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






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






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






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






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






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






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






33. 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






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






35. The process in which plates move and shift






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






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






38. The process in which water soaks into the ground






39. The crystals formed when igneous rocks cool underground






40. 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.






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






42. 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






43. 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






44. Water that has infiltrated the ground






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






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






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






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






49. The part of the Earth that we live on






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