Solar Physics Solar Wind

Solar wind storms can disrupt Earth's technology and create dazzling auroras.

0

What primary factor allows solar wind particles to escape the Sun's gravity and travel through space?

The solar wind is pushed away by the solar radiation pressure alone. Solar wind particles are pulled away by Earth's magnetic field. The high kinetic energy of particles resulting from the corona's extreme temperature.

Solar Physics Solar Corona

The Sun’s outer atmosphere blazes hotter than its surface, defying simple physics

0

What is the primary reason the solar corona is significantly hotter than the Sun’s surface?

The corona is closer to the Sun’s core, so it is naturally hotter Energy released by magnetic reconnection and wave heating in the corona The corona’s heat comes from sunlight directly heating its plasma

Solar Physics Solar Magnetic Cycle

The Sun's magnetic flip every 11 years sparks cosmic storms that ripple through space and Earth

0

What is the primary cause of the 11-year solar magnetic cycle's fluctuations in sunspot numbers?

Changes in Earth's orbit around the Sun Variations in the Sun's size and brightness unrelated to magnetic activity The twisting and flipping of the Sun's magnetic field due to differential rotation

Solar Physics Solar Wind

Solar wind storms can disrupt Earth's technology while painting the skies with auroras

0

What primary factor allows solar wind particles to escape the Sun's gravity and travel through space?

The extremely high temperature of the Sun's corona giving particles enough kinetic energy The Sun's rotation flinging particles outward at high speed Solar wind particles are pushed away by solar radiation pressure alone

Solar Physics Sunspot Number

Sunspots reveal the Sun's magnetic storms that ripple through space and Earth alike

0

Why did the ability to directly observe sunspots on the Sun's far side starting in 2006 significantly improve solar activity monitoring?

Because it eliminated the need to count sunspots on the Sun's near side. Because it allowed scientists to track sunspot development and solar storms more comprehensively, improving space weather predictions. Because sunspots on the far side have no impact on solar activity or Earth.

Solar Physics Coronal Loops

Magnetic battles in coronal loops unleash solar storms that ripple through space

0

What primary forces govern the formation and behavior of coronal loops in the Sun's atmosphere?

The interaction between magnetic flux tubes and plasma pressure Gravitational forces pulling plasma into loop shapes Solar wind pushing plasma into arch-like structures

Solar Physics Solar Cycle

The Sun’s magnetic heartbeat pulses every 11 years, shaping space weather and Earth’s skies

0

What causes the approximately 11-year solar cycle observed in the Sun’s activity?

The Earth’s orbit around the Sun causing seasonal changes in solar radiation. The periodic flipping of the Sun’s magnetic field polarity, leading to changes in sunspot numbers and solar phenomena. The Sun’s activity changes randomly without any underlying pattern or cause.
