Question

1. ____________ are extremely large explosions on the sun that can lead to geomagnetic storms on earth. (1 point)

sunspots
solar flares
the northern lights
ultraviolet radiation

Explanation:

Solar flares are sudden, intense bursts of energy from the sun. They release a large amount of electromagnetic radiation. When this radiation reaches Earth, it can interact with Earth's magnetic field, causing geomagnetic storms. Sunspots are cooler, darker areas on the sun's surface due to magnetic activity but are not the large explosions described. The Northern Lights (Aurora Borealis) are a result of charged particles from the sun interacting with Earth's atmosphere (often during geomagnetic storms but not the cause of the storms themselves). Ultraviolet radiation is a type of electromagnetic radiation from the sun but not specifically the large - scale explosion that leads to geomagnetic storms.

Answer:

B. Solar flares
