The water cycle is like a circleâ€”it has no beginning and no end. When the sun heats ocean water, it evaporates and forms clouds in the sky. When these particles get big enough, they can fall to Earth as precipitation in the form of rain, sleet, snow, or hail. When water hits the ground, it can change to liquid, soak into the ground, or run off and form streams or rivers. But it always makes its way back to the ocean, where the cycle â€œbeginsâ€ again.
All plants need sun, water, air, and food to grow. Plants are anchored to the ground by their roots, which take in nutrients from the soil. Stems and stalks hold up plants and give them shape, and also hold the plumbing system of the plant. Leaves are the place where food is made for the plant. Many plants make crops for us to eat.
