Planetary boundaries. Visualizations of the Planetary Boundaries; data for September 2023 [ 1] Planetary boundaries are a framework to describe limits to the impacts of human activities on the Earth system. Beyond these limits, the environment may not be able to self-regulate anymore. This would mean the Earth system would leave the period of ...
Plate tectonics (from Latin tectonicus, from Ancient Greek τεκτονικός (tektonikós) 'pertaining to building') [ 1] is the scientific theory that Earth 's lithosphere comprises a number of large tectonic plates, which have been slowly moving since 3–4 billion years ago. [ 2][ 3][ 4] The model builds on the concept of continental ...
Pelso Plate – Small tectonic unit in the Pannonian Basin in Europe. Timor Plate – Microplate in Southeast Asia carrying the island of Timor and surrounding islands. Tisza Plate – Tectonic microplate, in present-day Europe. Juan de Fuca Plate – Small tectonic plate in the eastern North Pacific – 250,000 km 2.

In meteorology, the planetary boundary layer ( PBL ), also known as the atmospheric boundary layer ( ABL) or peplosphere, is the lowest part of the atmosphere and its behaviour is directly influenced by its contact with a planetary surface. [1] On Earth it usually responds to changes in surface radiative forcing in an hour or less.
Planetary cartography, or cartography of extraterrestrial objects ( CEO ), is the cartography of solid objects outside of the Earth. Planetary maps can show any spatially mapped characteristic (such as topography, geology, and geophysical properties) for extraterrestrial surfaces. [1] Some well-known examples of these maps have been produced by ...
The planet has 6.9 Earth masses and 1.8–2.4 Earth radii, and with its close orbit receives 40 percent more stellar radiation than Earth, leading to surface temperatures of about 60° C. [144] [145] [146] HD 40307 g, a candidate planet tentatively discovered in November 2012, is in the circumstellar habitable zone of HD 40307. [147]
Earth is rounded into an ellipsoid with a circumference of about 40,000 km. It is the densest planet in the Solar System. Of the four rocky planets, it is the largest and most massive. Earth is about eight light-minutes away from the Sun and orbits it, taking a year (about 365.25 days) to complete one revolution.
