How do meteorologists grade their past forecasts?
Earth ScienceAsked by: Bee Williams How do meteorologists determine the forecast? Meteorologists use computer programs called weather models to make forecasts. Since we can’t collect data from the future, models have to use estimates and assumptions to predict future weather. The atmosphere is changing all the time, so those estimates are less reliable the further you
What model best describes the alignment of the Sun and Moon during a lunar eclipse?
Earth ScienceAsked by: Marcus Cahill How will you describe the alignment of Earth Moon and Sun in lunar eclipse? When the Moon passes between Sun and Earth, the lunar shadow is seen as a solar eclipse on Earth. When Earth passes directly between Sun and Moon, its shadow creates a lunar eclipse. Lunar eclipses can happen

How much does the biosphere contribute to Earth’s entropy production?
Earth ScienceAsked by: Karl Dance Why is entropy of Earth increasing? The decrease in entropy for the Earth system can be attributed to the incoming heat from the sun occurring at higher temperature on the planet’s surface during the day, whereas the same amount of heat (approximately, on average) leaving the planet during the subsequent night
