Clouds Easier - Clouds are large white or gray objects in the sky.
Clouds are a collection of very small drops of water or tiny pieces of ice that are held in the air.
Harder - A cloud is a mass of small water droplets or tiny ice crystals that float in the air. Clouds are formed of water that has evaporated from rivers, lakes, oceans, or moist soil and plants. Most clouds continually move and change shape. Clouds change as parts evaporate in dryer air or they are moved and reshaped by wind and air currents. Clouds are an important part of earth's weather.
