Low Earth Orbit satellites are moving at an altitude of roughly 160–1,500 kilometers above the Earth’s surface. They have a short orbital period, between 90 and 120 minutes, meaning they can travel around the planet up to 16 times a day. This makes them particularly well-suited to all...
these worms burrow within the top layers of soil and rarely come up to the surface, preferring instead to literally live within the earth. They are most commonly found in the uppermost layers of soil where they create semi-permanent, horizontal burrows or under rocks and logs, though some wi...
Six types of the crust are recognized. A more detailed division of the crust into sub-types has also been worked out.doi:10.1016/0264-3707(84)90026-7Beloussov, V.V.Pavlenkova, N.I.Elsevier LtdJournal of GeodynamicsV. V. Belousov and N. I. Pavlenkova, “Types of the Earth’s Crust...

In earth science, we often divide different types of mechanical weathering into two major categories: **fracturing**, which includes frost- & salt-wedging, and **abrasion**, including sandblasting and sea salt weathering.Frost Wedging or Freeze-Thaw ...
Tropical rainfall is mostly convective and its subseasonal-to-seasonal (S2S) prediction remains challenging. We show that state-of-art model forecast skill 3 + 4 weeks ahead is systematically lower over land than ocean, which is matched by a simila
Polar-orbiting satellites also pass over the planet's poles on each revolution, although their orbits are far less elliptical. The polar orbit remains fixed in space as Earth rotates inside the orbit. As a result, much of Earth passes under a satellite in a polar orbit. Because polar orbits...
Meteorite taxonomy (the practice and science of classification) or systematics is a topic of interest to both scientists and collectors. There is sort of a generally accepted taxonomic scheme for meteorites, but it is continually being revised and re-examined as we learn more about the origin of...
nature (agents of erosion and deposition) that leads to the formation of different landforms. At other times, it is the movement of the earth’s tectonic plates that contributes to their formation. Some landforms are created in a matter of few hours, while others take millions of years to ...
