Sunbeams striking the equator straight on and the poles at a slant.
Why does the equator get more solar energy per square meter than the poles, by Ari's reading (NASA)?
- The equator is closer to the Sun
- The poles sit in the Sun's shadow
- Sunlight strikes more directly there, so it spreads out less
- The poles are dark year-round
NASA: compared with the equator, about how much energy does 45° latitude get at an equinox, by Bo's reading?
- About 70%
- About 150%
- About 90%
- About 40%
Climate graph for two cities. Where are tropical (A) climates, with every month above 18 °C, by Kira's reading (NOAA)?
- High on mountains
- At 60° to 70° latitude, in the cold polar zones
- From the equator to about 15° to 25° latitude
- Near the poles
A mountain with temperatures dropping up its side. NWS: the normal lapse rate is 3.5 °F per 1,000 feet. How does temperature change as you climb, by Jun's reading?
- It drops 35 °F per 1,000 feet
- It stays the same
- It rises 3.5 °F per 1,000 feet
- It drops about 3.5 °F per 1,000 feet
A town at the foot of a mountain is 70 °F. About how warm is a spot 2,000 feet higher, using NWS's normal lapse rate, by Luz's math?
- About 0 °F
- About 63 °F
- About 77 °F
- About 66.5 °F
A mountain with temperatures dropping up its side. Why can high mountains near the equator be cold, by Milo's reading (NOAA, NWS)?
- Ocean currents freeze them
- They are closer to the Sun
- Elevation lowers the temperature, giving a highland climate
- They lie at a high latitude
A, on a coast, 10 °C, 20 °C; B, far inland, −5 °C, 27 °C. NOAA: day-night temperature swings are much greater over land than over water. Why, by Noah's reading?
- Water heats faster than land
- Sunlight heats only the top inches of soil but reaches deep into water
- Land holds its heat longer than water
- Water reflects most sunlight
Air rising and raining over a mountain, then sinking dry. Air rising and raining over a mountain, then sinking dry. Air rising raining sinking dry mountain What is a rain shadow, by Tala's reading (NOAA)?
- The dry leeward side of a mountain range
- The wet windward side
- A shadow cast by rain clouds
- A rainy valley floor between two mountain ranges
Why does the windward side of a mountain get more rain, by Zee's reading (USGS)?
Use the picture in question 8.
- Wind carries the rain uphill and away
- Air sinks and dries there before it reaches the peak
- Moist air rises, cools and drops its rain there
- The leeward side blocks the Sun
USGS: Kauai's summit gets more than 435 inches of rain a year; many leeward coasts get less than 40. About how many times more is 435 than 40, by Esme's math?
Use the picture in question 8.
- About 11 times
- About 4 times
- About 1.1 times
- About 395 times
