The Sun's Activities That Affect The Earth (4)

Solar wind (1)

Particles in plasma such as electrons, protons and alpha particles that erupt from the Sun to outer space travel together at high speeds known as solar wind

Solar wind (2)

Solar wind also carries the interplanetary magnetic field along with it

Solar wind (3)

The speed of solar wind is supersonic with values ranging from 250 km s-1 to 750 km s-1

Solar wind (4)

The speed, temperature and density of the solar wind changes along the course of its movement

Coronal mass ejections (1)

A coronal mass ejection is a huge cloud of plasma that erupts from the Sun and often occurs together with solar flares which are huge and strong

Coronal mass ejections (2)

A coronal mass ejection is an ejection of magnetic gas particle

Coronal mass ejections (3)

The coronal mass ejection spouts magnetic particles at high speeds into outer space and appears like an expanding cloud

Coronal mass ejections (4)

The magnetic particles from the coronal mass ejection take three days to reach Earth

Coronal mass ejections (5)

Like the charged gas particles in solar flares, the magnetic gas particles also react with atoms and molecules in Earth’s atmosphere to produce aurora

Solar flares (1)

A solar flare is a column of large amounts of charged gases erupting from the Sun and often occurs near sunspots
