GEOLOGY

Detailed explanation-1: -Second, ocean water expands as it warms, increasing its volume, so the water in the ocean takes up more space and sea level is higher. Since 1955, more than 90% of the excess heat held in the atmosphere by heat-trapping gases has made its way into the ocean.

Detailed explanation-2: -The warmer the water, the faster it evaporates. The warmer the air, the more water vapor it can hold. What role does temperature play in condensation? Condensation usually happens on cold surfaces, because it cools the water vapor, which changes phases.

Detailed explanation-3: -The greenhouse effect happens when heat trapped by gases in the atmosphere warms the Earth. The best description of this process is found in answer choice (E). Atmospheric gases trapping heat and warming the planet’s surface is the correct answer.

Detailed explanation-4: -Simply put, precipitation amounts are increasing as temperatures rise because warm air holds more water vapor: a 1°F rise in temperature equals as much as a 4% increase in atmospheric water vapor. Other factors can contribute to rainfall, including El Niño and La Niña .

Detailed explanation-5: -Globally, the primary sources of greenhouse gas emissions are electricity and heat (31%), agriculture (11%), transportation (15%), forestry (6%) and manufacturing (12%). Energy production of all types accounts for 72 percent of all emissions.
