Science Picture Notes for Chapters 5 and 6
Chapter 5 Lesson 1
How can the oceans be described?
Most of Earth’s water is in oceans .
Salinity is a measure of : the amount of salt in water.
Lesson 4
Where is fresh water found?
Only 3/10 of
Earth’s
water is
fresh water.
The amount
of usable
water is
limited!
An aquifer
is: the layer
of rock and
soil that
groundwater
flows
through.
About 7/10
of Earth’s
fresh water
is in ice.
Lesson 3
What are some California water sources?
Fresh water is California comes from lakes,
rivers, and groundwater.
An aqueduct is: a system of pipes that
carries water from a river or lake to an
area it is needed.
Reclamation is a way to recycle
wastewater. (helps to water crops)
Lesson 4
What is the water cycle?
The heating and cooling of air and water
change weather patterns.
The water cycle is: the
repeated movement of
water through the
environment in different
forms.
(evaporation,
condensation, and
precipitation)
Melting, evaporation, and
sublimation are
caused by energy
from the Sun.
Lesson 5
How do clouds form?
Without clouds
rivers and lakes
would dry up.
Clouds are
formed by rising
air.
Clouds are made
of: water droplets
or ice crystals
If the temperature
between the
ground and the
cloud is warmer
than 0 degrees
Celsius: rain falls.
Fog: is a cloud at ground level. It gets thicker as more droplets form.
Cirrus clouds: high altitude, thin, wispy, and white.
Clouds that grow vertically have rising air and are sometimes called
thunderheads (cumulo – nimbus)
Chapter 6 Lesson 1
How does air move?
Temperature differences cause convection currents.
Which is the rising and sinking of air in a circular pattern.
Differences in air
temperature cause
wind
Atmospheric pressure
(air pressure): is the
weight of air pushing
down on an area and
is caused by gravity.
As you higher up in
the atmosphere: air
pressure decreases.
The sun’s rays are
most concentrated
near the equator.
Lesson 2
What are air masses?
A front is a boundary between two air masses.
When warm air is surrounded by cold air, the warm air
will rise
An air mass is: a large body
of air with similar
temperature and amount of
water vapor.
Continental Polar Air: cold
and fairly dry
Continental Tropical Air:
warm and fairly dry
Maritime Polar Air: cold
and moist
Maritime Tropical Air:
warm and humid with lots
of moisture.
Lesson 3
What causes severe weather?
Thunderstorms: first - clouds grow as
water condenses in the rising air
Second – precipitation falls. The storm has
upward and downward air motion.
Third – clouds get smaller as precipitation
leaves.
Tornados: layers of wind in a storm blow
at different speeds and in different
directions.
Hurricanes: a strong cyclone that forms
over warm ocean water. They get their
energy from the warm ocean water.
Heat energy builds and drives the winds.
Lesson 4
How are weather forecasts made?
Barometer: shows air
pressure
Anemometer:
measures wind
speed
Rain gauge:
measures rainfall
amount
Doppler radar:
detects precipitation
and how wind
affects its
movement. Helps to
alert people to
severe weather such
as thunderstorms or
tornados.
