This is a list of gravity hills and magnetic hills around the world. A gravity hill is a place where a slight downhill slope appears to be an uphill slope due to the layout of the surrounding land, creating the optical illusion that water flows uphill or that a car left out of gear will roll uphill. Many of these sites have no specific name and ...
Earth's magnetic field deflects most of the solar wind, whose charged particles would otherwise strip away the ozone layer that protects the Earth from harmful ultraviolet radiation. [4] One stripping mechanism is for gas to be caught in bubbles of the magnetic field, which are ripped off by solar winds. [ 5 ]
Magnetic declination (also called magnetic variation) is the angle between magnetic north and true north at a particular location on the Earth's surface. The angle can change over time due to polar wandering .
Magnetic north versus ‘true north’ At the top of the world in the middle of the Arctic Ocean lies the geographic North Pole, the point where all the lines of longitude that curve around Earth ...
Water appearing to run uphill at Magnetic Hill in New Brunswick Magnetic Hill in Moncton, Canada. A gravity hill, also known as a magnetic hill, mystery hill, mystery spot, gravity road, or anti-gravity hill, is a place where the layout of the surrounding land produces an illusion, making a slight downhill slope appear to be an uphill slope.

The red dots show larger-magnitude earthquakes in Minnesota, Wisconsin, Michigan's Upper Peninsula and southern Ontario. The earthquake near Minnesota's western "bulge" is the Morris earthquake. This map and table shows where Minnesota's earthquakes have occurred. Earthquakes 1, 6, 9, 11, 15 and 18 are in the Great Lakes tectonic zone.
