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 ...
The North geomagnetic pole (Ellesmere Island, Nunavut, Canada) actually represents the South pole of Earth's magnetic field, and conversely the South geomagnetic pole corresponds to the north pole of Earth's magnetic field (because opposite magnetic poles attract and the north end of a magnet, like a compass needle, points toward Earth's South ...
[8]: 1 Some of the Penokean granites show iron enrichment similar to the magnetite series, rather than the low-oxygen concentration of the magnetic titanium oxides. [ 8 ] : 1 Penokean-age rocks in the northern Wisconsin and the Upper Peninsula of Michigan contain areas of low-pressure, low- to high-temperature metamorphism.
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 ...
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 .
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 state averages from 30–40 inches (76–102 centimetres) of precipitation annually. Snow cover tends to be intermittent in the southern part of the state, but persistent in northern Lower Michigan and especially in the Upper Peninsula. Michigan USDA Plant Hardiness Zone Map. The entire state averages 30 days of thunderstorm activity per year.
Like the North Magnetic Pole, the North Geomagnetic Pole attracts the north pole of a bar magnet and so is in a physical sense actually a magnetic south pole. It is the center of the 'open' magnetic field lines which connect to the interplanetary magnetic field and provide a direct route for the solar wind to reach the ionosphere.
