The new moon occurs when the moon is positioned between the earth and the sun. At a full moon the earth, moon and sun are in approximate alignment. The first quarter and third quarter moons happen when the moon is at a 90 degree angle with respect to the earth and sun. After the new moon, the sunlit portion is increasing but less than half, so it is a waxing crescent. After the first quarter the is still increasing but now it is more than half, so it is a waxing gibbous. After the full moon the light continually decreases this is called a waning gibbous. Following the third quarter is the waning crescent, which wanes until the light is completely gone. Hope this helps.

Answer:
Difficulties with estimates
Explanation:
Estimation (or estimating) is the process of finding an estimate, or approximation, which is a value that is usable for some purpose even if input data may be incomplete, uncertain, or unstable. The value is nonetheless usable because it is derived from the best information available. Typically, estimation involves "using the value of a statistic derived from a sample to estimate the value of a corresponding population parameter". The sample provides information that can be projected, through various formal or informal processes, to determine a range most likely to describe the missing information. An estimate that turns out to be incorrect will be an overestimate if the estimate exceeded the actual result, and an underestimate if the estimate fell short of the actual result.
