8th: Topic 2 Test Review

Hassam is making a model showing the interior of the sun. He discovers the interior of the sun consists of gaseous layers that produce and distribute heat energy. In which layer of the sun is most of the heat in the form of electromagnetic radiation?

• radiative zone

• core

• convection zone

• surface

With technological advances such as the JWST, astronomers can study distant stars. These stars can be compared to our sun to better understand them. Which feature of the sun do astronomers use to observe the sun's rotation?

• corona

• prominences

• sun spots

• sun spots

Our sun is a yellow main sequence star, while Betelgeuse is a red Supergiant. Which of the following correctly compares the temperatures of the sun and Betelgeuse?

• Betelgeuse is hotter than the sun, because red Supergiants are hotter than yellow stars.

• The sun is hotter than Betelgeuse, because yellow stars are hotter than red Supergiants.

• The sun is hotter than Betelgeuse, because it is so much larger than Betelgeuse.

• The sun and Betelgeuse are close to the same temperature, because both are visible from Earth.

Ethan visited the Crosby Observatory at the Orlando Science Center. The observatory houses the largest refracting telescope available to the public in Florida. One night, he observed several stars that all seemed to be equally bright. However, one of the astronomers explained that each star actually had a different absolute brightness. What information do you need to calculate a star's absolute brightness? Choose the two that apply.

• its distance from the sun

• its chemical composition

• its apparent brightness

• its color and temperature

• its distance from Earth

People are fascinated with the possibility of life on other planets. When looking for signs of life on other planets, scientists often look for planets that have similarities to Earth. According to the chart, which planet has a rotation most similar to Earth’s?

• Uranus

• Jupiter

• Mercury

• Mars
