Observational data collected by doppler radar, radiosondes, weather satellites, buoys and other instruments are fed into computerized NWS numerical forecast models. The models use equations, along with new and past weather data, to provide forecast guidance to our meteorologists.
The water cycle or hydrologic cycle is the continuous movement of water between the earth's surface and the air. Water molecules move from the atmosphere (or air) to the earth's surface and back again. Water moves from the atmosphere to the earth's surface via rain, snow, sleet or hail. It moves back to the atmosphere via evaporation. The sun's energy is the catalyst for the movement of water between the atmosphere and the earth's surface.
Answer: For instance, plants (biosphere) grow in the ground (geosphere), but to survive they absorb water (hydrosphere) and carbon dioxide (atmosphere). Nor are plants merely absorbing: they also give back oxygen to the atmosphere, and by providing nutrition to animals, they contribute to the biosphere.
Hope this helps...... Stay safe and have a Merry Christmas!!!! :D
