Global Warming quiz 2- Observed temperature changes
{The Earth's average surface temperature rose by approximately _______ per decade over the period 1906–2005.} - 7.0&deg;C - 0.7&deg;C + 0.07&deg;C {In the twentieth century, the rate of earth's average temperature rise was closest to} - 0.7 &deg;C per decade - 0.7 &deg;C per year + 0.7 &deg;C per century {Compared with the first half of the twentieth century, the rate of earth's average temperature rise during the second (latter) half was } - half as much - about the same + twice as much {Compared with the second half of the twentieth century, the rate of earth's average temperature rise during the first half was} - twice as much + half as much - about the same {The urban heat island effect refers to the fact that urban areas tend to be hotter than rural areas. The urban heat island effect is estimated to account for approximately  _____ of the temperature rise over the past century.} - 0% - 30% - 0.3% + 3% {Proxy temperatures measurements are defined as indirect inferences gathered from ice cores, tree rings, and so forth} + true -false {Proxy temperatures measurements are defined as measurements made using measurements from space.} - true + false {The Reconstructed Temperature (0-2000 AD) plot in "Observed Temperature Changes" shows temperature measurements. The solid black line represents} - tree proxy measurements + thermometer measurements - the Little Ice Age - the Medieval Warming Period - a 10 year average {The Reconstructed Temperature (0-2000 AD) plot in "Observed Temperature Changes" shows temperature measurements, as well as what curious feature? (See also Divergence problem)} - the Little Ice Age being less prominent than the Medieval Warming period - a divergence between the tree and pollen proxy measurements + a tiny gap at the end of the proxy measurements - the fact that the different proxy measurements deviate considerably from the average of all proxy measurements {A rise in the sea level is associated with global warming because} - ice and snow melts + both of these are true - water tends to expand as it warms {What happens when water is heated?} - it expands at temperatures below 3.98&deg;C and contracts above 3.98&deg;C + it expands at temperatures above 3.98&deg;C and contracts below 3.98&deg;C - it absorbs CO2 {No direct method exists that permits an independent measurement of the heat content of the oceans, other than the fact that the air is warming} - true + false {Ocean temperatures are increasing more slowly than land temperatures because oceans have more heat capacity and because evaporation cools the water.} + true - false {Ocean temperatures are increasing more slowly than land temperatures because the oceans are absorbing less heat energy from the sun} - true + false
