The correct response is:

using theoretical models combined with known data

Astronomers have formed their ideas about the layers of the sun by utilizing both theoretical models of stellar structure and behavior, along with observational data from various sources, such as solar observations and measurements of solar radiation.

Two astronomers are viewing temperature data from each of the sun's layers, but the layers aren't identified. Describe one way the scientists can use temperature to identify which layer they are studying.(1 point)
Responses

The highest temperatures are from the radiative zone.
The highest temperatures are from the radiative zone.

The lowest temperatures are from the core.
The lowest temperatures are from the core.

The highest temperatures are from the corona.
The highest temperatures are from the corona.

The lowest temperatures are from the photosphere.

The correct response is:

The highest temperatures are from the corona.

Astronomers can identify the layers of the sun by analyzing temperature data, knowing that the corona has the highest temperatures compared to the other layers. This information helps differentiate it from the core, radiative zone, and photosphere.

Which is the origin of the sun’s energy?(1 point)
Responses

nuclear fusion
nuclear fusion

burning hydrogen
burning hydrogen

charged particles
charged particles

solar flares

The correct response is:

nuclear fusion.

The sun's energy originates from the process of nuclear fusion, where hydrogen nuclei combine to form helium, releasing a tremendous amount of energy in the process.

Which of the following protects Earth's atmosphere from solar wind?(1 point)
Responses

magnetosphere
magnetosphere

radiative zone
radiative zone

hydrogen atoms
hydrogen atoms

convection currents

The correct response is:

magnetosphere.

The magnetosphere is the region around Earth that is influenced by its magnetic field, and it protects Earth's atmosphere from solar wind and other charged particles from the sun.
