The Hydrosphere and the Water
Cycle
The Three Major Process of the
Water Cycle
• Evaporation- “The process by which liquid water is
heated by the sun and then rises into the atmosphere as
water vapor”. Water always evaporates from the Earth’s
ocean’s, lakes, streams, and soil, but most of the water
evaporates from the ocean.
• Condensation- In this process water vapor creates
water droplets on dust particles. These water droplets
create clouds. In doing so the water droplets will run into
each other, stick together, and make larger heavier
droplets.
Condensation
“any form of water
that falls to the
Earth’s surface from
the clouds; includes
rain, snow, sleet, and
hail”.

“the concentration of all the
dissolved salts it contains”
If all the
water in the
oceans
evaporated
what was
left over
could make
a 180 mile
high and one
mile thick
wall of salt
around the
equator
Ocean Salinity on
average is about
3.5% by volume

Ocean Layers. Kalley



The surface layer is the warmest because it is
warmed by the sun and is at the top of the ocean
which is constantly mixed by wave action and
has all sorts of animals.
The Thermocline is the middle layer; decreasing
temperature with depth. It is the boundary
between warm and cold water. It has low levels
of sunlight.
Below the Thermocline is the deep zone. It is the
deepest zone, which is at the bottom of the
ocean with temperatures below freezing. It is
very dark and no sunlight reaches to it.

How do currents regulate
temperature?
Currents that circulate warm water cause
the land they flow past to have a more
moderate climate.
 Fact: storing and absorbing energy is one
of the most important functions of the
oceans.


Ex: the British isles are warmed by the
Gulf stream.
Surface Currents
Surface Currents circulate warm water to
the deeper parts of the ocean.
The water at the oceans surface is moved
by winds that blow in certain patterns
because of the spin of the earth.
Gabbie Parnau
Coriolis Effect
“The Curving of the path
of a moving object
caused by the earths
rotation”
“In physics, the Coriolis
effect is an apparent
deflection of moving
objects when they are
viewed from a rotating
reference frame.”
Gabbie Parnau
• Deep ocean currents form when cold, dense
water from the poles sink below warmer, less
dense ocean water and flows toward the
equator.
• When cold water sinks to the bottom of the
ocean it flows very slowly northward to produce
a deep current.
Katie Stauffer
The densest and coldest ocean water is located off
the coast of Antarctica .

 Earth’s
surface is covered by 70 to75
Percent.
 Only 3 Percent of the Water is Fresh.
Earth’s Fresh Water is Locked in Icecaps And
Glaciers. The Rest of the Fresh Water
Found in Lakes, Rivers and Underground.
What is a River System?
“A river system is
a flowing
network of rivers
and streams
draining a river
basin.”

What are Tributaries?
They are “smaller streams of rivers that
flow into larger ones.”

What is Groundwater?
‫ ﭹ‬It is made up of rain and melted snow that
has seeped through the ground.

What is Groundwater?
‫ ﭹ‬Water collected in sediment and rock
underground.
‫ ﭹ‬It only makes up about 1% of the Earth’s water.

How is Groundwater important?
‫ ﭹ‬It is the easiest source of fresh water,
so humans use it to drink.

How is Groundwater important?
‫ ﭹ‬We also use the water for agriculture.

What is an aquifer?
-“ a rock layer that stores and
allows the flow of groundwater.”
-”A formation, group of formations,
or part of a formation that contains
sufficient saturated, permeable
material to yield significant
quantities of water to wells and
springs.”

What is a recharge zone?
-”the surface of land
where water enters
an aquifer.”
