CCC Stability and Change Liquid water has existed on Earth's surface for at least 4 billion years, even as the sun's energy output has continued to increase. The total area of continents (now 39% of Earth's surface) may have grown in size over Earth's history. Think about what you know about the albedos of land and water. Does an increase in land area explain why Earth's surface hasn't heated to a point that the ocean has boiled away? Why or why not?

For a science project, a high school research team conducted a survey of local air temperatures. based on the results of the survey, the found that the average temperatures were around 10 degrees higher than expected. this result was wrong. the trouble with the survey was that most of the locations were exposed to direct sunlight and located over asphalt or sand, which resulted in higher temperatures than normal. this is a classic example of an error in which phase of inferential statistics?
