"Simple text and photos explain a year as a unit of time and Earth's orbit of the sun"--

Our modern understanding of the heliocentric universe developed five hundred years ago. Since the time of Copernicus and Galileo, scientists have made major strides in understanding how gravity, stars, and planets interact. Gravity, Orbiting Objects, and Planetary Motion explains how early ideas have given way to sophisticated, proven theories about the universe. The book aligns with Next Generation Science Standards and also presents a look at what...

An examination of the phenomena and scientific principles behind the changing of the seasons.

Invierno, primavera, verano y otoño—las estaciones son uno de los ciclos más familiares de la naturaleza. Pero, ¿por qué cambia el clima? Aprenda por qué los patrones climáticos cambian a lo largo de las estaciones. Winter, spring, summer, and fall—the seasons are one of nature's most familiar cycles. But why does the weather change? Learn why weather patterns change over the seasons.

In the early seventeenth century, Galileo Galilei posited that tides were a consequence of Earth s motion. Today we ve achieved an accurate understanding of the ways that orbiting objects interact to create visible and sometimes tangible effects on Earth. Earth, Sun, and Moon: Cyclic Patterns of Lunar Phases, Eclipses, and the Seasons explains the cycles that affect our daily lives and how the major figures in astronomy used the scientific method...
