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






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






4. 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






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






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






7. The process in which plates move and shift






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






9. Thew ay a mineral breaks along its crystalline structure






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






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






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






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






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






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






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






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






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






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






20. The act of using radioactive isotopes to date fossils






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






22. 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






23. 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






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






25. 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






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






27. 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






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






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






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






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






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






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






34. The degree that a mineral reflects light






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






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






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






38. The crystals formed when igneous rocks cool underground






39. The different ways a species can evolve






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






41. Degree to which a mnieral can be scratched






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






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






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






45. 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






46. Active boundary where tectonic plates meet






47. The part of the Earth that we live on






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






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






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