Document Summary
Thermometer: liquid in glass thermistor (electronic, liquid expands as temperature increases and the liquid is forced up the tube. The two most common used temperature scales in use today in meteorology are the. Fahrenreight scale (us) and the celsius scale (everyone else). 100 k: f = (temp(c) x 1. 8) + 32, c = (cid:4666)(cid:4667) (cid:2871)(cid:2870) (cid:2869). 8, k = temp (c) + 273. Earth"s observed temperature range is 265 f or 142 c. Radiation earth/sun relationships the reasons for the seasons (chapter 2 in textbook) We"re in the habitable zone: we"re not too close or too far just the right distance, at right distance so water can exist at all three phases, solid, liquid, gas. The earth revolves around in an elliptical path around the sun in 365. 25 days. Earth is closest to the sun on jan. 3rd: perihelion 147 million km to sun. Earth is furthest from sun on july 4th: aphelion 152 million km.
