What happens to water in puddles?
Key Concepts. When a puddle dries up, tiny particles of water break away from the liquid in the puddle and go into the air. The tiny water particles are called water molecules. Water on the ground goes into the air, becomes part of a cloud, and comes back down to Earth as rain.
How does a puddle form?
A puddle is a small accumulation of liquid, usually water, on a surface. It can form either by pooling in a depression on the surface, or by surface tension upon a flat surface.
How are we part of the water cycle?
A number of human activities can impact on the water cycle: damming rivers for hydroelectricity, using water for farming, deforestation and the burning of fossil fuels.
What role does water play in the water cycle?
Water plays many different roles on the Earth. The Sun’s energy causes water to evaporate from oceans and lakes into the atmosphere. Plants and animals also release water vapor into the atmosphere as they breathe. When the atmosphere cools, water vapor condenses; making clouds that might produce rain or snow.
What is a puddle of water?
noun. a small pool of water, as of rainwater on the ground. a small pool of any liquid. clay or the like mixed with water and tempered, used as a waterproof lining for the walls of canals, ditches, etc.
How do puddles dry up?
Students will be able to explain that puddles dry up because tiny particles of water (water molecules) break away from the puddle and go into the air. This process is known as the water cycle.
What is condensation in the water cycle?
Condensation is the process of a gas changing to a liquid. In the water cycle, water vapor in the atmosphere condenses and becomes liquid. Condensation can happen high in the atmosphere or at ground level. Clouds form as water vapor condenses, or becomes more concentrated (dense).

Is urination part of the water cycle?
Animals contribute water mainly through breathing, perspiration and urination. They also turn into water vapor and enter the water cycle, just like water evaporating from plant leaves. When animals consume water, they urinate to expel the excess, which then then evaporates and re-enters the water cycle.
What happens to the ocean water before the precipitation part of the water cycle?
Energy from the sun causes water on the surface to evaporate into water vapor – a gas. This invisible vapor rises into the atmosphere, where the air is colder, and condenses into clouds. Water drops form in clouds, and the drops then return to the ocean or land as precipitation – let’s say this time, it’s snow.
