What happens if magnetic field flips?
This is what has happened when the magnetic poles flipped in the past.
This could weaken Earth’s protective magnetic field by up to 90% during a polar flip.
Earth’s magnetic field is what shields us from harmful space radiation which can damage cells, cause cancer, and fry electronic circuits and electrical grids..
What are the 4 equinoxes?
These are known as the equinoxes: the autumnal equinox and vernal or spring equinox. It’s the moment at which the plane of Earth’s equator passes through the centre of the Sun’s disk, or the moment that the Sun passes the celestial equator. On these dates, there are approximately equal hours of daylight and darkness.
What is difference between Equinox and Solstice?
The equinox marks the time when daylight and night-time are approximately the same length, with solstice occurring on the longest and shortest days (in terms of sunlight).
Why is the solstice important?
21 this year) marks an important milestone. It’s the shortest day of the year and the longest night of the year, and signals a powerful transition point between seasons that is impossible to ignore. … In Pagan times the winter solstice was referred to as Yule and was a celebration of the Goddess (Moon) energy.
What happens if a CME hits Earth?
The most powerful solar storms send coronal mass ejections (CMEs), containing charged particles, into space. If Earth happens to be in the path of a CME, the charged particles can slam into our atmosphere, disrupt satellites in orbit and even cause them to fail, and bathe high-flying airplanes with radiation.
Which country has the longest day in the world?
IcelandFacts About the Midnight Sun in Iceland Iceland’s hours of daylight on the longest days of the year is 24 hours per day (May-July). Iceland’s hours of daylight on the shortest days of the year is 4-5 hours per day (December-January).
What happens during Solstice?
A solstice is an event occurring when the Sun appears to reach its most northerly or southerly excursion relative to the celestial equator on the celestial sphere. Two solstices occur annually, around June 21 and December 21.
Why does the solstice date change?
The exact orbital and daily rotational motion of the Earth, such as the ‘wobble’ in the Earth’s axis (precession), also contributes to the changing solstice dates. The solstices occur because the rotation axis of the Earth is tilted by an angle of 23.5 degrees from the vertical.
Who celebrates solstice?
The sacred day is also called Yule to pagans celebrating the birth of the new solar year, according to Circle Sanctuary, a prominent pagan group in America. Dozens of pagans and druids head to Stonehenge, an iconic site in England, to pay tribute to the sun during the solstice.

How often does the sun’s magnetic field reverse Weegy?
every 11 yearsThe Sun’s magnetic field reverses every 11 years.
What is the Earth’s solstice?
Solstice, either of the two moments in the year when the Sun’s apparent path is farthest north or south from Earth’s Equator. In the Northern Hemisphere the summer solstice occurs on June 20 or 21 and the winter solstice on December 21 or 22.
What happens when the Earth’s magnetic field flips reverses?
During an excursion or a reversal, the magnetic field is considerably weakened and allows many more cosmic rays to reach the surface of the planet. These energetic particles from space can be damaging to life on Earth if too many reach the surface.

A hemisphere’s winter solstice is the shortest day of the year and its summer solstice the year’s longest. In the Northern Hemisphere the June solstice marks the start of summer: this is when the North Pole is tilted closest to the Sun, and the Sun’s rays are directly overhead at the Tropic of Cancer.
