Scientists continue to study the sun and learn more about its structure and how it produces heat. In which layer of the sun does the most heat flow in the form of electromagnetic radiation?

• convection zone

• core

• radiative zone

• surface

Andres is on Earth and is looking at the sun. Which layer of the sun is he able to see? SC.8.E.5.6

• corona

• sunspot

• plasma

• photosphere

The sun is a ball of gas and plasma. Which of the following sentences best describes the rotation of the sun? SC.8.E.5.6

• The sun rotates rigidly like the solid planets do.

• The sun does not rotate at all.

• The equatorial regions of the sun rotate faster than the polar regions.

• The equatorial regions of the sun rotate slower than the polar regions.

Which of the following sentences best describe the convection zone of the sun? SC.8.E.5.6

• The energy is carry outward to the sun’s surface by the movements of rising hot gases and sinking cool gases.

• The energy is carry outward to the sun’s surface by the movements of sinking hot gases and rising cool gases.

• The energy is carry from the convection zone to the core by electromagnetic radiation.

• The energy that is coming from the core is carry to the convection zone by nuclear fusion.
