Crop circles refer to intricate patterns that appear mysteriously in crop fields overnight. They have been reported in countries around the world. While some believe they are caused by aliens, winds, or atmospheric phenomena, others argue they are elaborate hoaxes created by people. The exact origins of crop circles remain a mystery.

3. Crop circles refer to gigantic designs that appear in fields.
These designs are created by the crops being mysteriously
packed down.
People wake up in the morning to find clean edge intricate
patterns marked out in their fields that have been
constructed overnight with no sign of who made them.

6. Reasons To Happen
• Crop circles are organized harmonic that manifest around world – in
this case plants.
• This energy is comprised of light , sound and magnetism.
• In genuine formations the stems are not broken but, bent normally
about an inch off the ground and near the plant’s first node.
• In special cases, the stems are bent six inches from the top of the
seed head.

8. Crop Circle Features
• Crop circles, as the name implies, almost always involve circles — rarely
triangles, rectangles, or squares, though some designs contain straight or
curved lines. Perhaps not coincidentally, a circle is the easiest pattern for
hoaxers to create.
• Nocturnal creation. Crop circles are formed overnight, often sighted by
farmers or passersby the next morning. Though there seems no logical reason
for extraterrestrials or earth energies to only create patterns at night, it is
obviously a great advantage for hoaxers to create the designs under the cover
of darkness; full moon nights are especially popular.

9. Who Makes Crop Circles
The answer of who or what is creating
these crop formations is not an easy one
to answer. Some people claim they are the
work of UFOs. Others say they are a
natural phenomenon. Still others say they
are elaborate hoaxes perpetrated by teams
of circle makers. Lets see one by one.

10. Ufo's And Aliens
• Possibly the most controversial theory is that crop circles are the
work of visitors from other planets -- sort of like
alien calling cards.
• People who agree with this theory say that the circles are either
the imprint left by landing spacecraft or messages brought from
afar for us earthlings. Some eyewitnesses claim to have seen
UFO-like lights and strange noises emanating from crop circle
sites.

12. Due To Winds
• Probably the most scientific theory says that
crop circles are created by small currents of
swirling winds called vortices (similar to "dust
devils"). The spinning columns force a burst of
air down to the ground, which flattens the
crops. Vortices are common in hilly areas such
as parts of southern England.
• But the question remains -- how can a few
seconds worth of spinning air create such
intricate and perfectly defined crop circles

13. Due To Aircraft
• A few researchers have theorized that
small airplanes or helicopters stir
up downdrafts that push the crops down
into patterns.
• Recreation attempts so far have not been
able to produce the types
of downdrafts necessary to make the
perfectly round edges seen in most crop
circles.

14. Due To Human Energy
• Some researchers believe that the earth creates its
own energy, which forms the circles. One possible
form of earth energy is electromagnetic radiation. In
fact, scientists have measured strong magnetic fields
inside crop circles, and visitors have sometimes
reported feeling a tingling sensation in their body
while in or near the circles.
• In the early 1990s, American biophysicist Dr.
William Levengood discovered that crops in circles .

15. • Researchers of crop circles have linked
modern crop circles to old folkloric tales to
support the claim that they are not
artificially produced. Circle crops are
culture-dependent: they appear mostly in
developed and secularized Western countries
where people are receptive to New Age
beliefs, including Japan, but they don't
appear at all in other zones, such as Muslim
countries.

18. • Circles in the United Kingdom are not spread
randomly across the landscape, but they appear
near roads, areas of medium to dense population,
and cultural heritage monuments, such as
Stonehenge or Avebury and always in areas of
easy access.
• The scientific consensus is that most or all crop
circles are man-made, with a few possible
exceptions due to meteorological or other natural
phenomena.
