climate topic for grade 9

1. CLIMATE; DISTANCEOF
OCEAN
LAND AND WATER

2. OBJECTIVES
explain how distance from the
ocean affects climate
compare the effect of heat on water
and land

3. DAY TIME
•The climate of the place is influenced by the
surrounding bodies of water. Soil absorbs heat faster
than water. At the same time, soil releases heat faster
compared to water.
•These slow absorption and release of heat by the
body of water greatly affect the climate. Places that
are near the oceans have moderate climate as the
body of water regulates the temperature.

4. •Even as both soil and water absorb the same amount of
heat, the temperature of water rises more slowly than
that of soil. Because soil heats up faster than water, air
temperature above the sea is lower than above ground
during day time.
• Warm air thus moves out from land to sea, slowing
down the rise of air temperature above land. Thus,
places without a body of water nearby tend to have
higher air temperature during day time.
DAY TIME

5. • At night, soil cools down faster than water, so the air
temperature above ground is lower than that above the
sea. Warm air then flows from sea to land, so the drop
in air temperature above ground is moderated.
•Places that are far from the bodies of water have
extreme climates, as there are no immediate bodies of
water that will help to circulate the movement of cold
and warm air.
NIGHT TIME

6. •The reason why temperature of water rises or falls
more slowly than soil is that water has higher heat
capacity. Because of this, water also absorbs more
heat in warm days and slowly releases it in cold
days.
•That is why during summer, areas that are near a
body of water will have moderate temperature
because water absorbs more heat.
NIGHT TIME

7. •Similarly during winter, surrounding water
slowly releases heat causing the cooling
effect to become lesser than normal in the
nearby landmass.
