Main gases of the ionosphere (about 50 km; 31 miand above on this chart) vary considerably by altitude. The F layer or region, also known as the Appleton–Barnett layer, extends from about 150 km (93 mi) to more than 500 km (310 mi) above the surface of Earth. It is the layer with the highest electron density, which implies signals penetrating ...
The rotation axis of Earth is centered and vertical. The dense clusters of lines are within Earth's core. [2] Earth's magnetic field, also known as the geomagnetic field, is the magnetic field that extends from Earth's interior out into space, where it interacts with the solar wind, a stream of charged particles emanating from the Sun.
Layers of the ionosphere.The Kennelly–Heaviside layer is the E region. The Heaviside layer, [1] [2] sometimes called the Kennelly–Heaviside layer, [3] [4] named after Arthur E. Kennelly and Oliver Heaviside, is a layer of ionised gas occurring roughly between 90km and 150 km (56 and 93 mi) above the ground — one of several layers in the Earth's ionosphere.
The exosphere, which on Earth lies between the altitudes of about 700 kilometres (435 mi) and 10,000 kilometres (6,200 mi) The ionosphere, an ionized portion of the upper atmosphere which includes the upper mesosphere, thermosphere, and lower exosphere and on Earth lies between the altitudes of 48 and 965 kilometres (30 and 600 mi)
Earth’s inner core, a red-hot ball of iron 1,800 miles below our feet, stopped spinning recently, and it may now be reversing directions, according to an analysis of seismic activity ...
The submarine terrain of the ocean floor has an average bathymetric depth of 4 km, and is as varied as the terrain above sea level. Earth's surface is continually being shaped by internal plate tectonic processes including earthquakes and volcanism; by weathering and erosion driven by ice, water, wind and temperature; and by biological ...
Ancient helium that became trapped in Earth’s core when our planet formed billions of years ago may be leaking from lava flows, according to researchers. Earth’s core is leaking, scientists ...
The shifts are causing feedback beneath the surface, impacting the planet's molten core. Melting ice is slowing Earth's spin and causing changes to its axis, new studies find. The shifts are ...
