The earth is getting warmer due to the global warming. There are many climates all over the planet. Some areas of Earth have snow every day, and some are so dry they almost never have rain or snow

2. Global warming
Global warming – a gradual
increase in air temperatures near
Earth’s surface.
o The possible
consequences of global
warming are uncertain but
may be severe. They
include melting of polar
ice caps, rising sea levels,
drought, and an increase
in the frequency and
severity of storms.

3. Greenhouse effect
• Greenhouse effect – atmospheric heating
caused by certain gases in Earth’s atmosphere
that are transparent to sunlight but absorb
and reflect heat that comes from Earth’s
surface.
• The greenhouse effect gets its name from
the fact that the air inside a greenhouse
will often be warmer than the outside air.
The glass in a greenhouse is transparent to
sunlight but traps the heated air inside.

4. Greenhouse
gas
• Greenhouse gas – a gas in
Earth’s atmosphere that
absorbs and then re-radiates
heat.
• Examples of greenhouse
gases include water vapor,
carbon dioxide, methane,
nitrous oxide,
chlorofluorocarbons
(CFCs), and
hydrochlorofluorocarbons
(HCFCs).

5. Heat flow
•Heat flow – the transfer of
thermal energy from a
warmer object to a cooler
object. Vapor from boiling
water escapes into the cooler
air above the pan.

7. Natural heat flow
The natural uneven heating of things on
Earth’s surface and in the atmosphere, cause
wind, and allow the movement of air and
water vapor around the world.

8. What are sea breezes
and why do they occur?
• Sea breezes occur during hot, summer days because of
the unequal heating rates of land and water. During the
day, the land surface heats up faster than the water
surface. Therefore, the air above the land is warmer than
the air above the ocean. Now, recall that warmer air is
lighter than cooler air. As a result, warm air rises.
Therefore, the warmer air over the land surface is rising.
As the warm air over the land is rising, the cooler air over
the ocean is flowing over the land surface to replace the
rising warm air. This is the sea breeze and can be seen at
the top of the following image. The bottom of the following
image illustrates the land breeze that occurs at night.
Recall that the land surface cools quicker than the water
surface at night. Therefore, the warmer air over the ocean
is buoyant and is rising. The denser cool air over the land
is flowing offshore to replenish the buoyant warm air and
is called a land breeze.

9. At night, the roles
reverse. The air over
the ocean is now
warmer than the air
over the land. ... This
causes a small
temperature gradient
between the ocean
surface and the nearby
land at night and the
wind will blow from the
land to the ocean
creating the land
breeze.
