Science water cycle
Describe the movement of a water molecule as it moves through the water cycle by following the droplet through six consecutive processes.

Draw an image to represent each of the 14 processes. Include arrows to show the direction of movement

What can occur immediately after condensation?
...
What can occur immediately after deposition? melting, sublimation
...
Water uptake/absorption - energy is...
Absorption is a process where water is being taken from the groundwater by the roots of plants. Energy is not being released or absorbed (not change of state)
Human or animal excretion - energy is...
Animals and humans excrete water by sweating breathing and by passing urine. Energy is not being released or absorbed (no change of state).
condensation - energy is...
Condensation is when water changes from a gas (water vapor) to a liquid. - Energy is being released.
deposition - energy is...
Deposition is the change of state between the gaseous phase to the solid phases of matter. Skipping the liquid phase. Energy is being released.
Which process causes rain?
Evaporation causes rain because liquid water turns into water vapor.
Which process causes frost to form?
Freezing causes frost to form
freezing - energy is...
Freezing is when water changes from a liquid to a solid. Energy is being released.
Describe real life scenarios for each process.
Frost is an example of deposition where vapor turns directly into ice on a car windshield. An animal drinks water from a pond and then pees (or excretes) water back out When it is cold a pond may freeze. For example, ice cubes in a cold drink will gradually melt. A cup of water can evaporate into the air. When you're outside with a cold glass of water on a hot day and a film of water begins to wrap around the outside of the glass. In the winter the snow banks get smaller without turning into slush. Water that flows downhill into oceans, ponds, rivers, and lakes. When it rains there is no change of state When the rain, rains on the soil and goes into the soil in a garden. Heavy rain coming down and the soil absorbing the water Photosynthesis Heavy rain coming down and the soil absorbing the water
groundwater discharge - energy is...
Groundwater discharge is the process where water moves out of the ground. Energy is not being released or absorbed (no change of state.)
Groundwater storage - energy is...
Groundwater storage us water existing for long periods below the earth's surface. Energy is not being absorbed or released. (no change of state).
Where would a water molecule immediately end up after going through the process of transpiration?
It would end up in the atmosphere
Where would a water molecule immediately end up after going through the process of infiltration?
It would end up underground.
melting - energy is...
Melting is when water changes from a solid to a liquid. Energy is being absorbed.
What processes absorb energy?
Melting, evaporation, transpiration, and sublimation
precipitation - energy is...
Precipitation is water released from clouds in the form of rain freezing sleet snow or hail due to gravity. Most precipitation falls as rain. No change of state so no energy being released or absorbed
transpiration - energy is...
Transpiration is a process where liquid water is turned into vapor BY PLANTS. (similar to evaporation but different because of plants.) Energy is being absorbed
What is an example of runoff?
Water that flows downhill into oceans, ponds, rivers, and lakes.
Describe how clouds are formed or how dew forms on grass or how water collects on a mirror after a hot shower.
When water vapor hits a surface that is cooler it condenses. Some particle makes the water vapor to condense. When a cloud forms it means that water vapor condenses into liquid water.
What can occur immediately after melting?
freezing, runoff, infiltration
During which processes does water change states?
sublimation, evaporation, transpiration, melting, freezing, deposition, condensation
Which process causes dew and clouds?
Condensation causes dew and clouds because it is the change of state from gas to liquid.
What are the three ways water reaches the atmosphere?
Evaporation, deposition, and transpiration
runoff - energy is...
Runoff is a process where water runs over and down the surface of Earth Energy is not being released or absorbed (no change of state)
infiltration - energy is...
Infiltration is a process where water seeps into the ground. Energy is not being released or absorbed (no change of state).
Where would a water molecule immediately end up after going through the process of evaporation?
Into the atmosphere
What processes release energy?
Water vapor condenses into rain energy and is then released. The formation of ice releases energy.
evaporation- energy is...
Evaporation occurs when liquid water changes into water vapor. Some water evaporates from water on land but most evaporation occurs from the earth's oceans. - Energy is being absorbed.
sublimation - energy is...
Sublimation is a process where ice changes directly into a gas without turning into a liquid first (rare) Energy is being released.
