The parts of the water cycle
• Evaporation is the process by which water
changes from a liquid to a gas or vapor.
• Most evaporation occurs from the oceans
since they cover 70% of the Earth.
• Transpiration: plants grab water from the soil
through their roots then the water goes out
into the atmosphere.
– Condensation is responsible for the formation of
clouds.
– Condensation is the process by which water
changes from a gas or vapor to a liquid.
• Precipitation Water falling back to Earth’s
surface
– Rain
– Snow
– Sleet (mixture of rain and snow)
– Hail
New Record Hailstone
A hailstone which fell on July 23, 2010 at Vivian, South Dakota
• Surface Run-off- water flows from high to low
– Oceans, rivers, lakes
– Humans and urban developments affect run off
• Infiltration
– a portion of the water that falls as rain and snow
infiltrates into the subsurface soil and rock.

What are the steps of the
Carbon Cycle?
• Photosynthesis plants use photosynthesis to make
energy and grow. They take in carbon dioxide (CO2),
sunlight, and water and turn it into oxygen and sugar.
• Respiration (breathing)Every time you breathe you
turn oxygen into carbon dioxide.
• Decay When plants and animals die they decay.
When this happens, the carbon in their body will
either be released into the atmosphere or stored in
ground as fossil fuels.
• Combustion (burning)– When plants, trees, or fossil
fuels are burned, carbon is released into the
atmosphere again.
What are the steps of the
Nitrogen Cycle – In simple terms!!
• Nitrogen exists in the atmosphere as a gas, N2. This
Is not usable to plants and animals. It must be
converted into a different form to be usable.
• Bacteria convert the Nitrogen gas to Nitrates. This is
done in nodules in plant roots or in the soil.
• Plants absorb the Nitrates and animals get their
nitrogen by eating the plants or other animals.
• When plants and animals die, they are broken down
by decomposers and the Nitrogen compounds return
to the soil.
• Bacteria in the soil converts the Nitrogen compounds
back to Nitrogen gas (N2) and it is returned to the
