Question

water cycle review
part 1: a water molecules journey.
using the starting and ending location, fill out the other two columns. there may be more than one transition per line. the first line is done for you. the transition options are: evaporation, condensation, precipitation, seepage, collection, absorption, drinking, respiration, transpiration, urination, melting, and freezing.

starting location	ending location	transition(s) name(s)	what drives this/these transition(s)?
ocean	clouds	evaporation then condensation	gains energy then loses energy
clouds	river
river	animal
animal	clouds
clouds	glacier
glacier	groundwater

Explanation:

Step1: Clouds to River

Water in clouds falls as precipitation (rain, snow, etc.) and then is collected in the river. The force of gravity drives the water from the clouds down to the Earth's surface.
Transition(s) Name(s): Precipitation, Collection
What drives this/these transition(s)? Gravity

Step2: River to Animal

An animal drinks water from the river. The animal's need for hydration drives it to drink.
Transition(s) Name(s): Drinking
What drives this/these transition(s)? Animal's need for water

Step3: Animal to Clouds

An animal respires and also may urinate. Water vapor is released into the air through respiration and urine can evaporate. Heat energy from the environment drives evaporation and the natural process of respiration releases water vapor.
Transition(s) Name(s): Respiration, Urination (followed by Evaporation)
What drives this/these transition(s)? Heat energy for evaporation, natural body - processes for respiration

Step4: Clouds to Glacier

Water in the clouds freezes and falls as snow which accumulates to form a glacier. Cold temperatures in high - altitude or high - latitude regions drive the freezing process.
Transition(s) Name(s): Freezing, Precipitation
What drives this/these transition(s)? Cold temperatures

Step5: Glacier to Groundwater

As the glacier melts, water seeps into the ground to become groundwater. Heat energy from the sun or warmer temperatures drives the melting process, and gravity drives the seepage into the ground.
Transition(s) Name(s): Melting, Seepage
What drives this/these transition(s)? Heat energy for melting, gravity for seepage

Answer:

Starting Location	Ending Location	Transition(s) Name(s)	What drives this/these transition(s)?
River	Animal	Drinking	Animal's need for water
Animal	Clouds	Respiration, Urination (followed by Evaporation)	Heat energy for evaporation, natural body - processes for respiration
Clouds	Glacier	Freezing, Precipitation	Cold temperatures
Glacier	Groundwater	Melting, Seepage	Heat energy for melting, gravity for seepage
