Global methane concentration, 2004
Global methane concentration. Map showing the concentration of methane (CH4) gas in the stratosphere (about 10-50 kilometres in altitude) on 25th July 2004

Cavansite on mordenite. Cavansite (calcium vanadium silicate) has a rich blue colour that arises from the hydrous nature of its crystals

Sea floor spreading, artwork
Sea floor spreading. Artwork showing three stages in the process of sea floor spreading. The process takes millions of years and it is the process by which the continents move over the Earth

Earth layers, artwork
Earth layers. Cutaway computer artwork showing the layers that make up the structure of the Earth and the movement (arrows) of molten lava within them

Antarctic ozone hole, 2009
Antarctic ozone hole. Satellite image of the ozone hole (blue) over Antarctica (centre) on 10th September 2009. Ozone layer thicknesses are colour coded from purple (lowest) through blue

Greenland, artwork
Greenland. Artwork of the Arctic island of Greenland, as seen from space. This view looks north, towards the Arctic pack ice on the Earths curved limb

Climate change, conceptual image. The burning of coal produces carbon dioxide, a greenhouse gas that contributes to global warming

Noctilucent clouds, ISS image
Noctilucent clouds. International Space Station (ISS) image of the limb of the Earth, showing noctilucent clouds (polar mesospheric clouds, across top) in the upper atmosphere

Folded rock formation. Close-up of folds in a fallen block of rock. These folds are formed as the rock is deformed by immense pressures generated from within the Earths crust as it moves over

Sample of galena
MODEL RELEASED. Sample of galena, held in a hand. Galena (lead sulphide, PbS) is a mineral ore that is a major source of lead, a metal with many applications in industry and manufacturing

Earths internal structure, artwork
Earths internal structure. Cutaway artwork showing various subdivisions and layers from the Earths crust down to its iron core (depth of 6371 kilometres)

Oil drilling, conceptual image
Oil drilling. Conceptual artwork of a clamp being used to squeeze the Earth to extract oil. This image can represent oil drilling and other aspects of the oil industry

Earthquake types, artwork
Earthquake types. Artwork showing tectonic plate movements (arrows) and associated earthquakes (red concentric rings). Tectonic plates moving parallel to each other (left)

Icelandic volcanoes, artwork
Icelandic volcanoes. Artwork showing how Iceland (left) is part of the Mid-Atlantic Ridge, with the land on either side moving apart (white arrows) and volcanoes (red)

Tectonic plate boundaries, artwork
Tectonic plate boundaries. Artwork showing two types of boundary associated with the formation and destruction of an oceanic section of a tectonic plate

Subduction zone processes. Cutaway artwork showing the geological processes that occur at a subduction zone between two tectonic plates

Rock formation and erosion cycle. Cutaway artwork showing the cycle by which rocks are formed and eroded. At top, volcanic activity forms new rock on the Earths surface as molten rock (lava)

Antarctic ozone hole maximum, 2008
Antarctic ozone hole maximum. Satellite image of the maximum extent in 2008 of the ozone hole (blue) over Antarctica (centre)

Blue Marble image of Earth (2010)
Blue Marble image of Earth. Composite satellite image of Earths eastern hemisphere, centred on India. North is at top. This image is one of a set released in March 2010 using Blue Marble

Global carbon dioxide transport, 2008. Map showing the global variation in atmospheric carbon dioxide levels in July 2008

Global tropospheric methane, 2005. Map showing the global variation of the greenhouse gas methane in the troposphere in August 2005

Sea surface density, global map. The density of the surface water of the worlds oceans is calculated from measurements of temperature and salinity

Alexander von Humboldt, German naturalist
Alexander von Humboldt (1769-1859), German naturalist and geographer. At 27, Humboldt inherited enough money to plan an expedition with botanist Aime Bonpland to South America (map shown)
