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






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






3. The part of the Earth that we live on






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






5. Mountains made up by faults - a huge crack in rock where movememnt happens where tectonic plates pull apart






6. 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.






7. The limited supply of water there is






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






9. A layer of rock that contains fossils






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






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






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






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






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






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






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






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






18. The different ways a species can evolve






19. The crystals formed when igneous rocks cool underground






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






21. Water that has infiltrated the ground






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






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






24. 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.






25. 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






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






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






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






29. The act of using radioactive isotopes to date fossils






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






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






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






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






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






36. The degree that a mineral reflects light






37. 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






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






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






40. Thew ay a mineral breaks along its crystalline structure






41. Active boundary where tectonic plates meet






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






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






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






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






46. 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






47. Changes that were made to the DNA and RNA






48. 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






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






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