What do we know about the SUN?
Just a few facts…
Our sun:
-is 93 million miles away
-is an intensely hot star
-gives energy and light that are essential
for survival.

The Greenhouse Effect…what is
that?
Facts about the “greenhouse
effect”:
Facts:
-only a small amount of solar radiation reaches the
earth.
-some of that radiation is reflected back into space, but
some stays to warm the earth.
-the atmosphere prevents heat from escaping back into
space too quickly.
Thank goodness…
The earth has been compared to the glass
walls and roof of a greenhouse, which trap
the sun’s warmth for growing plants.
Without the earth’s so-called “greenhouse”
effect the earth would be too cold for
most living things.
The Earth’s Revolution and the
Seasons:
A few questions:

Why do the regions near the equator have
warmer climates than the northern and
southern poles?
– The sun’s rays always fall most directly at or
near the equator, while the northern and
southern regions receive less direct sunlight,
making them colder.
How does the heat of the sun cover
all of the earth?
Distributing the Sun’s heat…

Convection: the transferring of heat from
one place to another.

Two types:
– Wind: movements in air
– Current: movement in water

The blue arrows stand for cool currents and the red stand for warm.
Next up….precipitation!

Precipitation
– Is all forms of water that fall from the
atmosphere on to the earth’s surface.
Types:
rain
hail
snow
sleet
Types of Precipitation:
