__________________ is the continuous movement of water between the atmosphere, the land,
and the oceans. On Earth, water is held in natural bodies of water like lakes or oceans or manmade bodies called ______________________. For the water cycle to begin water must
______________ from Earth. Evaporation means water changes from a liquid to a gas. Another
way water enters the atmosphere is through ________________________ (water evaporates
from leaves). Once water is in the atmosphere, it then ____________________ to form a cloud
(changes from a gas to a liquid). Once a cloud becomes too heavy water then ____________
back to earth in the form of rain, snow, sleet or hail. Water __________________ across the
land before soaking in or _________________ into the soil. Water will collect beneath the
Earth’s surface. This is known as _______________________________.
The Hydraulic Cycle. This cycle is also known as the _______________________.

Carbon is found in all life and in the Earth’s atmosphere. Plants, through __________________,
convert carbon dioxide to carbohydrates (sugars), and release oxygen as a by-product. In turn
plants are _______________________ (eaten) by other organisms. Once these organisms die,
________________________ break down the dead organism and release
_______________________ back into the atmosphere. Trees, oceans and lakes act as
__________________________; they trap large amounts of carbon and release it back into the
atmosphere slowly over time. Humans disrupt the carbon cycle by burning or
_____________________ organic materials.

The ________________________ is the pathway for moving nitrogen between biotic and

and ________________________ in all living organisms. The atmosphere is 78% nitrogen
(N2). Animals cannot use nitrogen gas. Instead bacteria in the soil called
____________________________________ convert the atmospheric nitrogen into
__________________ or nitrate. This process is called ______________________________.
_______________________ can also cause nitrogen fixation.
Once in the soil, plants absorb the nitrogen through their roots and then organisms eat the
plants. When organisms die, ___________________________ release the nitrogen from the
bodies back into the atmosphere in a process called ____________________________.

Water Cycle is the continuous movement of water between the atmosphere, the land, and the
oceans. On Earth, water is held in natural bodies of water like lakes or oceans or man-made
bodies called Reservoirs. For the water cycle to begin water must Evaporate from Earth.
Evaporation means water changes from a liquid to a gas. Another way water enters the
atmosphere is through Transpiration (water evaporates from leaves). Once water is in the
atmosphere, it then Condenses to form a cloud (changes from a gas to a liquid). Once a cloud
becomes too heavy water then Precipitates back to earth in the form of rain, snow, sleet or hail.
Water Runs Off across the land before soaking in or Infiltrating into the soil. Water will
collect beneath the Earth’s surface. This is known as Ground Water.

The Nitrogen cycle is the pathway for moving nitrogen between biotic and abiotic factors on
Earth. Nitrogen is essential for the formation of amino acids and proteins in all living
organisms. The atmosphere is 78% nitrogen (N2). Animals cannot use nitrogen gas. Instead
bacteria in the soil called Nitrogen Fixing bacteria convert the atmospheric nitrogen into
ammonia or nitrate. This process is called Nitrogen Fixation. Lightning can also cause
nitrogen fixation.
Once in the soil, plants absorb the nitrogen through their roots and then organisms eat the
plants. When organisms die, decomposing bacteria release the nitrogen from the bodies back
into the atmosphere in a process called Denitrification.

The phosphorus cycle originates from the ground. Phosphorus is released the ground by the
weathering and leaching of rocks. Plants then absorb the phosphorus through their roots.
Organisms consume the plants and excrete waste in the form of urine and feces. Phosphorus is
also release when an organism dies. Decomposing bacteria the break down the dead organism
or waste products. Finally, the Phosphorus is released back into the soil to either create new
rocks or be reabsorbed into plants.
