1. B
2. C
3. B
4. A
Yeah! I know it is so late but you are correct! :)
yep CGM is right for connections academy
correct!
nope. i got 1/4
1. To determine which statement about the sun's structure is true, we need to consider our knowledge of the sun. The sun does not have a solid surface, so statement A is false. The sun is composed of several layers, including the interior and atmosphere, so statement B is true. The sun's interior is not similar to Earth's with a core, mantle, and crust, so statement C is false. The outermost layer of the sun is actually called the corona, not the radiation zone, so statement D is false. Therefore, the correct answer is B.
2. To determine the correct order of layers in the sun's atmosphere, we need to know the arrangement of these layers moving outward from the sun. The correct order of layers is the following: photosphere, chromosphere, and corona. So, we can look for the option that lists these layers in the correct order. Option C lists photosphere, chromosphere, and corona in the correct order, so the answer is C.
3. To find the term that refers to areas of gas on the sun's surface that are cooler than the gases around them, we need to know the correct terminology. Prominences and sunspots are both related to the sun, so we may need to understand the distinction between them. However, cool spots are not commonly used to describe these areas on the sun's surface, so option C is unlikely to be correct. Solar winds, on the other hand, are not associated with areas of gas on the sun's surface, so option D is also unlikely. Prominences, which are vast, arching loops of gas, are not specifically cooler than the gases around them, so option A is incorrect. Sunspots, however, are areas of gas on the sun's surface that appear darker and cooler than the surrounding gases, making option B the correct answer.
4. To accurately compare the temperature of the sun's core to its surface, we need to have a knowledge of the temperatures involved. The sun's core is known to be extremely hot, while the surface of the sun is also very hot but comparatively cooler. The core of the sun has a temperature of around 15 million degrees Celsius, while the surface temperature, known as the photosphere, is around 5,500 degrees Celsius. Comparing these temperatures, we can see that the core is indeed much hotter than the surface. However, the core is not more than a million times hotter than the surface, so options C and D can be eliminated. The core is more than a thousand times hotter than the surface, so option A is correct, making it the most accurate statement.
