What is climate?
The average weather conditions at
a particular place over a long period
of time (> 30 years).
2) What is weather?
Weather is the day-to-day
conditions of a particular place.
1)
Enduring Understanding
Heating of Earth’s surface and
atmosphere by the Sun drives
convection within the atmosphere
and oceans, producing winds and
ocean currents.
Essential Question
How do land forms
affect climate?
Climate
Climate is the condition of the atmosphere near
the earth's surface at a certain place on earth.
 It is the long-term weather of that area (at least
30 years).
 Two of the most important factors in
determining an area's climate are air
temperature and precipitation.
 The climate of a region will determine what
plants will grow there, and what animals will
inhabit it.

Bell Work
3/12/14
Explain how greenhouse gases
are formed and how they
impact global warming.
Greenhouse gases, such as
carbon dioxide (CO2) increase
in the atmosphere due to burning of fossil
fuels, which includes emissions from cars &
trucks. Increased CO2 in the atmosphere
causes the temperature of the earth to
increase. This human impact negatively
effects the environment by causing polar ice
caps to melt at a faster rate, raising sea
levels. It also negatively affects areas of the
Earth where crops are grown. The climate
may become too warm to grow food.
Greenhouse Effect
Pollution/burning of fossil fuels
CO2 in the atmosphere increases
CO2 prevents radiation from re-radiating out of
the atmosphere so temp of the earth increases.
Polar ice caps melt at a faster rate,
raising sea levels.
Also, the climate in crop growing areas may
become too warm to grow food.
Measuring Energy
7) How much energy is need to melt 100 g of
ice?
100 g x 80 Cal = 8,000 calories
g
8) How many calories of heat energy must be
added to 10 g or iron to raise its temp 10C?
ESRT p. 1
Properties of Water

Capillary Action – is the ability
of a liquid to flow in narrow
spaces without the assistance
of, and in opposition to, external
forces like gravity.

void or "empty“ spaces in a
material.
Total volume of empty space
÷ total volume of soil
What materials would you need to calculate
the porosity of a sample of soil?
Runoff
Vocabulary
Runoff – the water flow that
occurs when the soil is infiltrated
to full capacity and excess water
from rain, meltwater, or other
sources flows over the land.
This is the primary agent in
water erosion.
Which will result in greater runoff and stream discharge?
a. an area that is vegetated
or
an area that is barren
b. an area that has a steep slope
or
an area that is flat
c. ground that is frozen
or
ground that is unfrozen
d. ground that is saturated
or
ground that unsaturated
Vocabulary
1)
Humidity – the amount of
water vapor in the
atmosphere.
Vocabulary
1)
Arid – a climate having little
or no rain; too dry to
support vegetation.
Vocabulary

Infiltration – water entering
the upper parts of the
Earth’s lithosphere under
the influence of gravity.

Planetary Wind & Moisture Belts in
the Troposphere
A. Troposphere
1. Lowest layer of earth’s atmosphere.
2. Contains atmosphere’s water vapor and
suspended particles important in the formation of
clouds and precipitation.
3. Most weather takes place here in the
troposphere.
4. Weather – condition of the atmosphere in a
particular place at a particular time.
5. Temperature generally decrease as altitude
increases (about 6.5oC per km).
B. Stratosphere
6. Above the troposphere from 12 km to 50 km.
7. Temperature remains nearly the same up to
20 km.
8. Above that, temperature increases as
altitude increases.
9. The upper stratosphere is warmer because of
the presence of the ozone layer.
Ozone Layer
10. Highly reactive gas molecules of O3
11. Ozone absorbs UV radiation in sunlight and filters
most of it out before the UV radiation reaches the
earth’s surface.
12. The energy absorbed from UV radiation is
converted into thermal energy warming the upper
stratosphere.
13. The presence of ozone is extremely important
because UV rays can be harmful.
Earth’s Atmospheric Layers–Another View
C. Mesosphere
14. Located above the stratosphere, 50km to
80 km.
15. Temperature decreases as altitude increases
(it gets colder the higher up you go).
16. At the top of this layer, temps reach -90 C.
D. Thermosphere
17. From 80 km out into space.
18. The thin air of this layer gradually merges
with space.
19. Temperature increases rapidly with altitude.
20. Temperature ranges from -90C to over 1000C.
21. High temp – due to thermosphere absorbing
solar radiation, the molecules move very fast.
22. Auroras & meteors occur here.

Vernal Equinox
An equinox occurs twice a year,
around 20 March (vernal equinox)
and 22 September (autumnal
equinox) when daytime and night
are approximately equal.
The word is derived from the Latin
aequus (equal) and nox (night).
Why Equinox?
The Earth's 23.5º axial tilt creates
the changing seasons.
That tilt means that one of the
hemispheres receives more
sunlight most of the year.
But at equinox - neither the
northern nor southern hemispheres
receive more sunlight.

What type of heat transfer

Bell Work Answers
1.
2.
3.
A front is the boundary that forms when
2 unlike air masses meet.
Clouds and precipitation often form
at fronts.
Convection currents cause warm air
near the equator (tropical air masses)
to move toward the poles and cold air
at the poles (polar air masses) to
move toward the equator.
Weather Smart – Heat, Wind &
Pressure
Back page Questions #
1)
How does wind start – uneven heating of
the surface of the Earth by solar
radiation.
2) The North & South Pole are always cold.
3) Warm air rises at the equator & cold air
sinks at the North & South poles and the
wind mixes the air.
4) The windiest time of day is the afternoon.
5) If we didn’t have air we wouldn’t
be able to live.
6) Around low pressure you find cloudy,
warm weather with more precipitation.
7) A strong wind makes you feel colder
b/c the movement of air increases
the body’s heat loss due to convection.
8) The warmest temps - near the equator.
9) The jet stream makes weather move
around the world.
10) Differences in air pressure moves air.

1.
What is an occluded front?
2.
Which front travels faster a cold
front or a warm front?
A. Air Pressure

The atmosphere has weight (and exerts
pressure) because of Earth’s gravity

Air pressure is the force exerted by the weight
of a column of air.

Air Pressure at sea level = 1 atmosphere =
101,325 N/m2
Or 760 mm of mercury.
Air Pressure
Temperature effects air pressure:
1.
Temperature
Pressure (low)
b/c warm air is less dense
2.
Temperature
Pressure (high)
b/c cold air is more dense
Air Pressure

As altitude increases, air pressure and
density decrease.

Air pressure is measured using a barometer.

As air pressure increases the column of
mercury in the barometer goes up.

Which fact about weather was most

A. Cold Front




When a cold air mass overtakes a warm air
mass
Cold air (denser) remains close to the ground
and moves under the warm air mass
Cold fronts usually move quickly and are steep,
lifting the warm air mass rapidly
Produces cumulus clouds, strong winds, and
severe thunderstorms


When a warm air mass overtakes a cold air
mass
Advancing warm air mass rises up over the
cold air mass
Warm fronts usually move gradually and are
gentle slopes
Produces stratus clouds, steady rain, and
occasionally heavy showers
C. Stationary Fronts

When 2 unlike air masses form a boundary,
but neither is moving

Often result in clouds and steady rain or snow
for several days
Occluded Fronts

When a warm air mass is caught between two
cooler air masses

The colder air masses force the warmer air
mass to rise

Generally accompanied by cloudy skies and
precipitation
Front Symbols
Cold front symbol - “ice”

short lived down pour
Warm front symbol – “sunrise”
