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.

6. An opening - or rupture - in a planet's surface or crust - which allows hot molten rock - ash - and gases to escape from below the surface - Volcanic activity involving the extrusion of rock tends to form mountains or features like mountains over a p






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






8. Characterized by similar temperatures and moisture levels






9. The major mountains tend to occur in __________ - indicating tectonic plate boundaries and activity






10. Both gravity and inertia work together to keep planets in orbit around the sun - Inertia makes a planet travel in a straight line






11. After the moon has waxed through crescent - quarter - and gibbous phases - a ________ appears - At that time - the moon rises at sunset - and we see all of its illuminated side - Then the phase wanes gradually to another new moon






12. Two types of mountains are formed - depending on how the rock reacts to the tectonic forces






13. Improved land - use practices can limit erosion by using techniques such as...






14. Common: wind - clouds - rain - snow - fog - dust storms - Less common: natural disasters such as tornadoes - hurricanes - and ice storms






15. 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






16. An area of frequent earthquakes and volcanic eruptions associated with the plate boundaries surrounding the Pacific Ocean - In a 40000 km horseshoe shape - associated with a nearly continuous series of oceanic trenches - volcanic arcs - and volcanic






17. Zero degrees latitude - generally has a tropical climate (warm and wet); at the extreme northern and southern latitudes (polar regions) - the climate is very cold and dry






18. Tends to move slowly and is replenished slowly - and so it can remain in aquifers for thousands of years






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






20. A region of the earth that has uniform standard time - usually referred to as the local time - divided into standard and daylight saving (or summer)






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

24. Oceans cover __ of the earth's surface






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