Solar Wind

The video explains how extreme solar activity affects Earth, particularly through charged particles that can disrupt satellites and technology. The Earth's magnetic field offers protection, but at the poles, auroras occur due to solar wind interactions. Various satellites, including the cluster mission, monitor solar activity to provide a three-dimensional view of solar wind patterns. These observations help understand the impact on Earth's magnetic field and modern technologies.

What natural phenomenon is caused by the interaction of solar winds with the Earth's ionosphere?

• Auroras

• Volcanic eruptions

• Earthquakes

• Tornadoes

Why can't a single satellite provide a complete view of solar wind patterns?

• It lacks the necessary instruments

• It cannot observe the sun at night

• It is too far from the sun

• It cannot provide a three-dimensional view

What is the primary purpose of the cluster mission launched in 2004?

• To measure the temperature of the sun

• To provide a three-dimensional view of solar wind patterns

• To explore the surface of the sun

• To capture images of solar flares

How are the cluster mission satellites arranged in their orbit?

• In a tetrahedral formation

• In a straight line

• In a random pattern

• In a circular formation

What do the cluster mission satellites measure to understand the Earth's magnetic field?

• Gravitational waves

• Solar radiation levels

• Magnetic field changes, high energy electrons, and plasma density

• Temperature changes
