Water on Earth moves between the oceans and land and through the processes of evaporation and condensation . Energy from the Sun heats Earth unevenly, causing air movements that result in changing weather patterns . The solar system consists of planets and other bodies that orbit the Sun in predictable paths . The solar system includes the planet Earth, the Moon, the Sun, eight other planets and their satellites, and smaller objects, such as asteroids and comets. The path of a planet around the Sun is due to the gravitational attraction between the Sun and the planet.
Scientific progress is made by asking meaningful questions and conducting careful investigations .
Heat moves in a predictable flow from warmer objects to cooler objects until all objects are at the same temperature . Many phenomena on the Earth s surface are affected by the transfer of energy through radiation and convection currents . Scientific progress is made by asking meaningful questions and conducting careful investigations .
