Answer:
The photosphere, the chromosphere and the ionosphere.
Explanation:
You did not list any layers in your question, however, the sun is composed of mainly 6 layers;
- The core
- The radiative zone
- The convective zone
- The photosphere
- The chromosphere
- The corona
The photosphere is the visible layer of the sun, however, it is very bright even when viewed with a telescope. A filter has to be used to reduce the intensity of the light. This filter is called a myler filter. It is added to the lens of the telescope. Using this, the photosphere can be seen using a telescope.
The chromosphere is an irregular layer above the photosphere. Due to the extremly high temperature, hydrogen emits light which gives off a reddish color. This is known as the H-alpha emmision. Therefore, to see this layer with a telescope, a special filter have to be fitted to the lens of the telescope. This filter is called the hydrogen alpha filter.
The corona is the outermost part of the sun atmosphere, however, it is hidden by the sun's bright surface. It can be seen during a total eclipse. This is when the moon covers the bright photosphere.
Answer:
A. July
Explanation:
It refers to the actual months of winter in Australia: June 1 through to August 31.
C is the correct answer.
Barrow Alaska is an example of a polar tundra climate that is marked by low vegetation growth, cold temperatures, low amounts of precipitation, and no true summer.
Tropical. In this hot and humid zone, the average temperatures are greater than 64°F (18°C) year-round and there is more than 59 inches of precipitation each year.
Dry. These climate zones are so dry because moisture is rapidly evaporated from the air and there is very little precipitation.
Temperate. In this zone, there are typically warm and humid summers with thunderstorms and mild winters.
Continental. These regions have warm to cool summers and very cold winters. In the winter, this zone can experience snowstorms, strong winds, and very cold temperatures—sometimes falling below -22°F (-30°C)!
Polar. In the polar climate zones, it’s extremely cold. Even in summer, the temperatures here never go higher than 50°F (10°C)!
