o d 25

question 3 (1 point)
what dramatic solar event was captured by the solar dynamics observatory on august
a a coronal mass ejection (cme)
o b a solar eclipse
o c a meteor shower
o d a sunspot

Explanation:

The Sun accounts for about 99.86% of the solar - system's mass. The Solar Dynamics Observatory is designed to observe the Sun, and a coronal mass ejection (CME) is a significant solar event it can capture. Solar eclipses occur between the Sun, Earth, and Moon and are not events the Solar Dynamics Observatory primarily captures. Meteor showers occur in Earth's atmosphere and are not solar events in the sense relevant to the observatory. Sunspots are features on the Sun but are not as dramatic an event as a CME.

Answer:

1. C. 99.86
2. A. A coronal mass ejection (CME)
