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






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






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






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






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






6. 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






7. The degree that a mineral reflects light






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






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






10. 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






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






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






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






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






15. Active boundary where tectonic plates meet






16. 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






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






18. 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.






19. The part of the Earth that we live on






20. The act of using radioactive isotopes to date fossils






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






22. Degree to which a mnieral can be scratched






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






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






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






26. 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






27. 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






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






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






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






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






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






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






34. The machine that is used to measure earthquakes






35. The limited supply of water there is






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






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






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






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






40. The process in which plates move and shift






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






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






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






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






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






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






47. A layer of rock that contains fossils






48. 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






49. Water that has infiltrated the ground






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