__________________ 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 ______________________. 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 – oxygen Cycle :

Decomposing Bacteria Combusting Carbon Sinks Consumed Photosynthesis Carbon Dioxide

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

abiotic factors on Earth. Nitrogen is essential for the formation of _____________________

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 ____________________________.

The _____________________ originates from the ground. Phosphorus is released the ground by the ________________________ and ______________________ of rocks. Plants then _________________ the phosphorus through their roots. Organisms consume the plants and excrete ______________________ in the form of urine and feces. Phosphorus is also release when an organism _______________________. Decomposing _____________________ 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.

Ground Water Run Off Water Cycle Evaporate Transpiration Precipitates Infiltrating Condenses Reservoirs

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.

Carbon – oxygen Cycle :

Decomposing Bacteria Combusting Carbon Sinks Consumed Photosynthesis Carbon Dioxide

Carbon is found in all life and in the Earth’s atmosphere. Plants, through photosynthesis,

convert carbon dioxide to carbohydrates (sugars), and release oxygen as a by-product. In turn

plants are consumed (eaten) by other organisms. Once these organisms die, decomposing

bacteria break down the dead organism and release carbon dioxide back into the atmosphere.

Trees, oceans and lakes act as carbon sinks; they trap large amounts of carbon and release it

back into the atmosphere slowly over time. Humans disrupt the carbon cycle by burning or

combusting organic materials.

Nitrogen Cycle :

Denitrification Nitrogen Cycle Amino Acids Lightning Ammonia Decomposing Bacteria Nitrogen Fixation Nitrogen Fixing Bacteria Proteins

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.

Phosphorus Cycle

Bacteria Leaching Phosphorus Cycle Waste Absorb Weathering Dies

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.

Human Impact Overview

THREAT CAUSE POSSIBLE RESULTSGREENHOUSE EFFECT Burning fossil fuels and

clearing forests increases amount of carbon dioxide in atmosphere

Melts polar ice caps, causes overall drastic changes in climate throughout the world

ACID RAIN Burning fossil fuels makes rain more acidic

Acid rain destroys forests and poisons the environment

OZONE DEPLETION Chemicals eat away the ozone layer

Increases chances of skin cancer
