Also, the title animation takes too long- modify or
animate the text all at once (and not by level).
Sol - (in Latin for the sun) the
star at the center of the Solar System.
It is almost perfectly Spherical and
consists of hot plasma interwoven with
magnetic fields. It has a
diameter of about
1,392,000 km, about

STRUCTURE
1. The core of
the Sun is considered to
extend from the center to
about 0.2 to 0.25 solar
radius.
2. The radiation zone
or radiative zone is a layer
of a star's interior where

CONVECTION ZONE
3. The convection zone
of a star is the range of
radii in which energy is
transported primarily by
convection.
4. The photosphere of an astronomical object
is the region from which externally received light

STRUCTURE
5. The chromosphere is the second
of the three main layers in the Sun's
atmosphere and is roughly 2,000 kilometers deep.
6. A corona is a type of plasma "atmosphere
of the Sun or other celestial body, extending
millions of kilometers into space, most easily seen
during a total solar eclipse , but also observable in a
coronagraph.
STRUCTURE
7. Sunspots are temporary phenomena
on the photosphere of the Sun that appear
visibly as dark spots compared to surrounding
Regions.
8. Granules on the photosphere of the Sun
are caused by convection currents within the
Sun's convective zone.
STRUCTURE
9. A prominence is a large, bright feature
extending outward from the Sun's surface, often
in a loop shape.
BEHAVIOR
A geomagnetic storm that is caused
by the sun is a temporary disturbance of the
Earth's magnetosphere caused by a
disturbance in the interplanetary medium. A geomagnetic
storm is a major component of space weather and provides
the input for many other components of space weather.
A geomagnetic storm is caused by a solar windshock wave or
cloud of magnetic field which interacts with the Earth's
magnetic field. The increase in the solar wind pressure initially

An increased amount of energy into the magnetosphere.
BEHAVIOR
A solar flare is a sudden brightening observed over the
Sun's surface or the solar limb, which is interpreted as a large
energy release of up to 6 × 1025 joules of energy. These are
not visible from Earth's surface.

Add the following to your report:
1) How does the Sun make life possible on Earth?
2) How should we behave in response to the Sun’s
activities? (UV radiation, etc.)
