This donut-like structure runs parallel to the equator in a ring around the ... study of life on Earth and other planets. Earth's outer core has a radius of around 2,160 miles (3,480km) - making ...

However, we have shown in this study that the low-velocity region is only near the Equator. Earth's outer core has a radius of around 3,480 km, which makes it slightly bigger than the planet Mars.

Hurricanes, also known as typhoons or cyclones, cannot cross the Equator due to the Coriolis effect. This phenomenon, caused by Earth's rotation, produces a force that is too weak at the Equator ...

Imagine a piece of string wrapped around the Earth's equator - that's about 40,000km ... of a circle is directly proportional to the radius. Double the radius, double the circumference.

First, I’m going to find out which half of the Earth he’s on. Running around the middle of the planet is an imaginary line called the Equator. Well I’m on the half that’s above the Equator ...

The idea of geosynchronous satellites is to find an orbit over the equator in which the satellite ... We know all the other variables: G, mass of earth, and the period. Thus we only have to solve for ...

The vernal equinox signals the astronomical start of spring in the Northern Hemisphere, with the sun crossing above Earth's equator, moving from south to north, at 5:01 a.m. EST (0901 GMT ...
