CSET Earth

Subjects : cset, science
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.

18. Paleontology: Fossil evidence indicates the similarity of fossils on both sides of the Atlantic Ocean - Continental 'jigsaw puzzle': The outlines of the continents seem to fit together






19. Huge systems of stars - Milky Way is estimated to have 100 billion stars arranged in a great disk






20. Under solar conditions - gases are undergoing _____ to heavier elements with the increase of prodigious quantities of energy






21. Natural chemical compounds that are the crystals that make up rocks - Each has a specific composition or narrow range of composition






22. The variety of ways by which water moves across the land - This includes both surface runoff and channel runoff - As it flows - the water may percolate into the ground - evaporate into the air - become stored in lakes or reservoirs - or be extracted






23. Runoff and groundwater are stored as ________ in lakes






24. Igneous rock that cools beneath the earth's surface - Examples: plutons - dikes - and batholiths






25. Rising air currents take the vapor up into the atmopshere where cooler temperatures cause it to condense into ____






26. Formed from calcium carbonate - also an example of chemical sedimentary rocks - like roock salt - can contain organic or once - living matter and can record the history of that matter's formation in features such as strata - fossil evidence - and rip






27. Less than 1% of the earth; this relatively thin zone (5 to 25 miles) contains the only rocks we can study - even in the deepest mines or drill holes






28. Erosion in many places is increased by human land use - Poor land - use practices include deforestation - overgrazing - unmanaged construction activity - and road building






29. Travels around the earth each month - - Distance from the earth averages 237000 miles - Has rugged topography formed billions of years ago by volcanic eruptions and meteorite impacts - Mass is 1/6th that of Earth






30. Further caused by the elliptical orbit of the earth - Earth reaches perihelion (the point in its orbit closest to the sun) in January - and it reaches aphelion (farthest point from the sun) in July - Also depend on factors such as proximity to oceans






31. The science of the atmosphere and weather

37. Younger beds were originally deposited above older beds






38. (or summer time zones) include an offset (typically +1 hour) for daylight saving time






39. Largest zone of the planet (68%); crystalline silicates - rich in magnesium - calcium - and iron; very hot and mainly solid - but local melting to magma is the source of volcanic eruptions






40. A land form that stretches above the surrounding land in a limited area - with a peak - Usually produced by the movement of lithospheric plates
