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.

23. The runoff produced by melting snow






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






25. Characterized by similar temperatures and moisture levels






26. The spectra of distant objects display a red shift - which is interpreted as meaning that they are rapidly receding from us - This apparent expansion of the universe has given rise to the big bang theory of cosmology - in which one primeval mass expl






27. Bbreaking along flat surfaces






28. Igneous rock that forms on the earth's surface - Examples obsidian - basalt - and pumice






29. Takes approx. seven and a half earth months to revolve around the sun - Takes approx. eight earth months to rotate on its axis - a day on ________ is longer than a year

40. The difference between levels of ocean water at high and low tides






41. The sun and oceans can also affect the weather of land - If the sun heats ocean waters for a period of time - water can evaporate - Once evaporated into the air - the moisture can spread over nearby land - thus making it cooler
