How does solar weather affect Earth's magnetosphere? Select the two correct answers. (1 point)

A. It causes geomagnetic storms.

C. It generates auroras.

Which describes a difference between solar wind and a geomagnetic storm? Select the three correct answers. (2 points)

A. Geomagnetic storms are associated with CMEs; solar wind is associated with the constant activity in the sun.

B. Geomagnetic storms travel at the speed of light, while solar wind takes four days to reach Earth.

C. Geomagnetic storms are constant; solar wind occurs only occasionally.

D. Solar wind sometimes results in geomagnetic storms; geomagnetic storms do not cause solar wind.

E. Geomagnetic storms occur only occasionally; solar wind is constant.

A. Geomagnetic storms are associated with CMEs; solar wind is associated with the constant activity in the sun.

B. Geomagnetic storms travel at the speed of light, while solar wind takes four days to reach Earth.

E. Geomagnetic storms occur only occasionally; solar wind is constant.

The correct answers are A. It causes geomagnetic storms and C. It generates auroras.

To find the correct answers, we need to understand the relationship between solar weather and Earth's magnetosphere.

The solar weather, specifically solar activity such as solar flares and coronal mass ejections (CMEs), can have several effects on Earth's magnetosphere. Let's analyze each answer choice to determine the correct ones:

A. It causes geomagnetic storms - This is a correct answer. Solar weather, particularly CMEs, can trigger geomagnetic storms on Earth. When the charged particles from a CME interact with Earth's magnetosphere, it can cause disturbances and fluctuations in the magnetic field, leading to geomagnetic storms.

B. It forms radiation belts - This answer is incorrect. Radiation belts are regions of charged particles trapped by Earth's magnetic field. They are not directly formed due to solar weather.

C. It generates auroras - This is a correct answer. Solar weather can cause increased auroral activity. When solar particles interact with Earth's magnetosphere, they can energize the particles in Earth's atmosphere, resulting in the beautiful light displays known as auroras.

D. It develops solar wind - This answer is incorrect. Solar wind is a continuous stream of charged particles emitted by the Sun, not generated by solar weather's impact on Earth's magnetosphere.

Therefore, the two correct answers are:
A. It causes geomagnetic storms.
C. It generates auroras.
