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






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






3. A layer of rock that contains fossils






4. Era from 3.8 to 2.5 biillion years ago with the beginning of the geologic record and the formation of the first forms of rocks and bacteria






5. 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






6. The process in which water soaks into the ground






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






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






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






10. 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






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






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






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






14. Thew ay a mineral breaks along its crystalline structure






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






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






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






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






19. Active boundary where tectonic plates meet






20. Degree to which a mnieral can be scratched






21. Water that has infiltrated the ground






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






23. The period where the first fish were formed






24. 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






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






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






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






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






29. The limited supply of water there is






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






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






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






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






34. Molten rock






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






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






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






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






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






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






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






42. The degree that a mineral reflects light






43. 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






44. The machine that is used to measure earthquakes






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






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






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






50. The different ways a species can evolve
