Clouds begin to form when water vapor in the air reaches the correct altitude, dew
point, and temperature.
Atmosphere layers are distinguished by their composition, temperature, and altitude.
Troposphere: layer of Earth’s atmosphere that is closest to Earth’s surface.
In the thermosphere, temperatures can increase up to 1,700°C.
When water in lakes and rivers evaporates, it changes to water vapor.
Temperature is a measure of how fast air molecules are moving.
Factors that can have an effect on weather include temperature, cloud cover, wind
speed, humidity, air pressure, and wind direction.
Changes in temperature and pressure can cause winds to occur.
Drops of water or ice that become too large to be suspended in clouds are called
precipitation.
During an occluded front a fast moving cold front overtakes a slower moving warm
front.
A hurricane is a storm with winds over 120 km/h that can last several weeks.
Earth’s oceans cover nearly ¾ (75%) of Earth’s surface.
Water for Earth’s oceans originally came from water vapor from volcanoes.
Photosynthesis is a process that needs sunlight as a source of energy to make food.
The thermocline is the layer in the ocean where temperature varies with depth.
You are on the western coast of the Untied States. If the ocean currents stopped
flowing, the temperature would most likely increase (less wind).
Erosion caused by waves can destroy shorelines and beaches.
When deep cold water with nutrients rises to the surface, upwelling occurs.
When discussing waves, the horizontal distance between the highest or lowest points
of two successive waves is referred to as wavelength.
When the top of a wave moves faster than the bottom of a wave, the wave collapses,
forming a breaker.
Tides are caused by gravitational pull.
Ecosystems include organisms and any nonliving factors, such as water or sunlight.
In bodies of water, most plankton drift, rather than swim.
When organisms excrete waste or die and decompose, their nutrients do not disappear
or change. They are merely recycled.
Out of all of the marine organisms, plankton are some of the more common
organisms that contain chlorophyll.
Additional Information to Study
 Know at least six factors of weather.

Be able to explain how the ocean can have an effect on your life, even though there is
not an ocean anywhere near us.
