Identify the two layers that surround the sun's innermost layer. Select the two correct answers.(1 point)

Question

Responses

photosphere
photosphere

radiative zone
radiative zone

convection zone
convection zone

chromosphere

Answer 1

The two layers that surround the sun's innermost layer (the core) are:

1. Radiative zone
2. Convection zone

So, the correct responses are "radiative zone" and "convection zone."

Answer 2

Which do solar flares and coronal mass ejections have in common? Select the two correct responses.(1 point)
Responses

They are caused by the sun's changing magnetic field.
They are caused by the sun's changing magnetic field.

They appear as dark spots on the sun's surface.
They appear as dark spots on the sun's surface.

They tend to occur during minimum points in the solar cycle.
They tend to occur during minimum points in the solar cycle.

They are explosive events that can affect Earth.

Answer 3

The two statements that solar flares and coronal mass ejections have in common are:

1. They are caused by the sun's changing magnetic field.
2. They are explosive events that can affect Earth.

So, the correct responses are:

• They are caused by the sun's changing magnetic field.
• They are explosive events that can affect Earth.

Answer 4

Which set of terms describes a realistic cause-effect relationship between solar weather and Earth's magnetosphere? Select the two correct answers.(1 point)
Responses

radiation belt -- aurora
radiation belt -- aurora

geomagnetic storm -- aurora
geomagnetic storm -- aurora

solar wind -- interplanetary magnetic field
solar wind -- interplanetary magnetic field

coronal mass ejection -- geomagnetic storm

Answer 5

The two sets of terms that describe a realistic cause-effect relationship between solar weather and Earth's magnetosphere are:

1. Geomagnetic storm -- aurora
2. Coronal mass ejection -- geomagnetic storm

So, the correct responses are:

• geomagnetic storm -- aurora
• coronal mass ejection -- geomagnetic storm

Answer 6

For a few hours, some satellites experienced electrical failure and at the same time, radio communications at high latitudes were also disrupted. Which is an astronomer most likely to predict was the cause?(1 point)
Responses

a geomagnetic storm
a geomagnetic storm

solar energetic particles
solar energetic particles

coronal mass ejections
coronal mass ejections

solar flares

Answer 7

An astronomer is most likely to predict that the cause of the electrical failures in satellites and the disruption of radio communications at high latitudes was a geomagnetic storm.

So, the correct response is:

• a geomagnetic storm

Answer 8

Which accurately describes solar weather? Choose the two correct answers.(1 point)
Responses

The intensity of solar weather is constant and unchanging.
The intensity of solar weather is constant and unchanging.

The intensity of solar weather changes frequently.
The intensity of solar weather changes frequently.

Solar flares and sunspots increase as solar maximum approaches.
Solar flares and sunspots increase as solar maximum approaches.

Solar flares and sunspots increase as solar minimum approaches.

Answer 9

The two statements that accurately describe solar weather are:

1. The intensity of solar weather changes frequently.
2. Solar flares and sunspots increase as solar maximum approaches.

So, the correct responses are:

• The intensity of solar weather changes frequently.
• Solar flares and sunspots increase as solar maximum approaches.
