WebOct 14, 2024 · This bulge exists because of a force created by Earth's rotation. As a result, a person on the equator is over 13 miles farther from Earth's center than a person on the … WebFeb 28, 2024 · High tides and low tides are caused by the moon. The moon's gravitational pull generates something called the tidal force. The tidal force causes Earth—and its water—to bulge out on the side closest …
CWNA Chapter 5: How Can the Earth Bulge if it’s Flat
The planet Earth has a rather slight equatorial bulge; its equatorial diameter is about 43 km (27 mi) greater than its polar diameter, with a difference of about 1⁄298 of the equatorial diameter. If Earth were scaled down to a globe with an equatorial diameter of 1 metre (3.3 ft), that difference would be only 3 mm (0.12 in). While too small to notice visually, that difference is still more than twice the largest deviations of the actual surface from the ellipsoid, including the tallest mountains and … WebThat is equivalent to a hypothetical decrease in Earth radius and an increase of Earth bulge. Example. In normal weather conditions, the service range of a transmitting station at an altitude of 1500 m. with respect to receivers at sea level can be found as, See also.

WebJan 31, 2024 · The reason for this is obvious: as Earth's shape is very similar to a sphere – the surface between you and the ship is not entirely flat but "bulges" up a bit. That is … Earth bulge. In telecommunications, Earth bulge refers to the effect of earth's curvature on radio propagation. It is a consequence of a circular segment of earth profile that blocks off long-distance communications. Since the vacuum line of sight passes at varying heights over the Earth, the propagating radio … See more Line-of-sight propagation is a characteristic of electromagnetic radiation or acoustic wave propagation which means waves travel in a direct path from the source to the receiver. Electromagnetic transmission includes … See more Low-powered microwave transmitters can be foiled by tree branches, or even heavy rain or snow.
