What causes solar flares?

• Magnetic energy release

• Nuclear fusion reactions

• Gravitational pull

• Cosmic radiation

What is a coronal mass ejection (CME)?

• A coronal mass ejection (CME) is a type of solar flare.

• A coronal mass ejection (CME) is a significant release of plasma and magnetic field from the solar corona into space.

• A coronal mass ejection (CME) is a phenomenon that occurs only on Earth.

• A coronal mass ejection (CME) is a burst of gamma rays emitted by the Sun.

Why is it important to monitor the sun and its magnetic field?

• Geomagnetic Storms caused by the sun can destroy power lines

• The sun provides nearly all of the energy on Earth

• Solar storms can damage communcation and navigation satallites

• All of these are good reasons to study the sun.

What is solar wind?

• A type of wind that blows on the surface of the Earth.

• A type of wind that blows on other planets in the solar system.

• A stream of charged particles ejected from the upper atmosphere of the Earth.

• A stream of charged particles ejected from the upper atmosphere of the Sun.

How does solar wind affect Earth's magnetosphere?

• Solar wind strengthens Earth's magnetosphere.

• Solar wind interacts with Earth's magnetic field and can cause disturbances in the magnetosphere.

• Solar wind has no effect on Earth's magnetosphere.

• Solar wind causes the magnetosphere to expand.

What are geomagnetic storms?

• Disturbances in the Earth's magnetosphere caused by solar wind and solar flares.

• Electromagnetic waves emitted by the Earth's core.

• Intense thunderstorms that occur in the Earth's atmosphere.

• Changes in the Earth's climate caused by volcanic activity.

What causes geomagnetic storms?

• Solar flares

• Volcanic eruptions

• Disturbances in the Earth's magnetosphere

• Tectonic plate movements
