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






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






3. The period where the first fish were formed






4. 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.






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






6. The crystals formed when igneous rocks cool underground






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






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






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






10. The act of using radioactive isotopes to date fossils






11. The part of the Earth that we live on






12. 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






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






14. The process in which plates move and shift






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






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






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






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






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






20. Molten rock






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






22. The degree that a mineral reflects light






23. 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






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






25. 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






26. 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






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






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






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






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






31. 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.






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






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






34. Thew ay a mineral breaks along its crystalline structure






35. 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






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






37. A layer of rock that contains fossils






38. The different ways a species can evolve






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






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






41. 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






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






43. Water that has infiltrated the ground






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






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






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






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






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






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






50. 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
