Parts of the Sun

• Drill How many Earths could we fit inside the
  sun?
• Objective SWBAT identify and describe the
  structures of the sun in order to compare the
  properties of the sun to the characteristics of
  the planets.
• HW Diagrams due Thursday

The Sun is Comprised Of

• A round collection of Hydrogen and Helium divided
  into 3 layers.
• A dense atmosphere divided into 3 layers.

Oct. 16th of the Sun

• Drill Label each part of the sun with the
  following 3 words Convection Zone, Core, and
  Radiation Zone.

Is this the atmosphere or main body of the sun?

A Description of our Sun

• The Sun is comprised of three layers
• A dense center that produces heat/energy through
  nuclear fusion
• A middle layer that carries the heat to the
  exterior portion of sun
• An exterior that creates currents that exchange
  heat with the atmosphere. As the heat is
  transferred to the atmosphere cooler air is
  carried back to the middle to heat up again.

• The atmosphere is comprised of three layers
• The area closest to the sun produces light waves
  that we see
• The middle area that serves as a transition zone
• The exterior layer which is the largest layer of
  the suns atmosphere where charged particles
  continually escape.

Definitions

• Corona Exterior layer of the sun. The largest
  area of the atmosphere extending from the
  chromosphere outward millions of kilometers into
  space. Visible portion during a solar eclipse.
• Core Dense center of the sun where nuclear
  fusion occurs.
• Chromosphere Transition zone of the atmosphere
  between the photosphere and corona.

9
Definitions

• Convection Zone Area beyond the radiation zone
  where materials are heated, rise to the top,
  cool, then sink back to the bottom of the zone.
• Photosphere Lowest part of the atmosphere and
  the layer from which light is given off.
• Radiation Zone Area of the sun that surrounds
  the core. Transfers energy from the core to the
  convection zone.
