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 4.6 to 3.8 billion years ago when the Eaerth formed and the planet cooled off






2. 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






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






4. Thew ay a mineral breaks along its crystalline structure






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






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






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






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






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






10. Molten rock






11. The limited supply of water there is






12. 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






13. The different ways a species can evolve






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






15. The part of the Earth that we live on






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






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






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






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






20. 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






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






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






23. The act of using radioactive isotopes to date fossils






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






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






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






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






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






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






30. The process in which plates move and shift






31. The crystals formed when igneous rocks cool underground






32. 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






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






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






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






36. 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






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






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






39. Areas of great heat and activity in the earth's mantle where shield volcanoes can form






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






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






42. A layer of rock that contains fossils






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






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






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






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






47. Active boundary where tectonic plates meet






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






49. 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.






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