The Palmason Model is a depth, distance, temperature and heat flow gradient model of crustal accretion mechanism through the Iceland lithosphere which denotes the spreading material trajectories from a rift axis.
 The material erupting at the rift axis will tend to sink down, due to thermal subsidience and spreading, to a depth of many kilometers, while lava flows spreading to a distance of many kilometers away from the rift axis on the surface will sink down to shallower depth.
 Surface erosion can expose such preserved materials.
Malacoctenus hubbsi, the Redside blenny, is a species of labrisomid blenny native to the Gulf of California extending to the Pacific coast of southern Baja California.
 It is found in rocky areas at depths of from 1 to .
 This species can reach a length of 9 cm TL.
In geology, a piercing point is defined as a feature (usually a geologic feature, preferably a linear feature) that is cut by a fault, then moved apart.
 Reconfiguring the piercing point back in its original position is the primary way geologists can find out the minimum slip, or displacement, along a fault.
 This can be done on a large scale (over many kilometers), a small scale (inside a single outcrop or fault trench) or even a single hand sample/rock (see image).
The Gulf of California (also known as the Sea of Cortez, Sea of Cortés or Vermilion Sea; locally known in the Spanish language as Mar de Cortés or Mar Bermejo or Golfo de California) is a marginal sea of the Pacific Ocean that separates the Baja California Peninsula from the Mexican mainland.
 It is bordered by the states of Baja California, Baja California Sur, Sonora, and Sinaloa with a coastline of approximately 4000 km .
 Rivers which flow into the Gulf of California include the Colorado, Fuerte, Mayo, Sinaloa, Sonora, and the Yaqui.
 The gulf's surface area is about 160000 km2 .
Ellerslie is a residential neighbourhood in southeast Edmonton, Alberta, Canada.
 While City of Edmonton documents note that there are diverse stories related to Scottish settlers introducing the name Ellerslie, it is known that the name was applied to the local school district by 1895, and to the local post office in 1896, when it was still a rural area many kilometers south of the early boundaries of the recently (1892) incorporated Town of Edmonton.
The Telial stage is one of the stages in the life cycle of a parasitic heteroecious fungus.
 It is discernible by the formation of large teliospores that the fungi produces to overwinter.
 The telial stage of heteroecious parasitic fungi is spent on the secondary host plant.
 A primary aecial stage is spent parasitizing a separate host plant which is a precursor in the life cycle of heteroecious fungi.
 Spores are released from the telia in the spring.
 The spores can spread many kilometers through the air, however most are spread near the host plant (Brand, 2004).
Ellerslie is an area in the southeast portion of the City of Edmonton in Alberta, Canada.
 It was established in 1999 through Edmonton City Council's adoption of the Ellerslie Area Structure Plan, which guides the overall development of predominantly residential neighbourhoods in the area.

A fissure vent, also known as a volcanic fissure or eruption fissure, is a linear volcanic vent through which lava erupts, usually without any explosive activity.
 The vent is often a few meters wide and may be many kilometers long.
 Fissure vents can cause large flood basalts which run first in lava channels and later in lava tubes.
 After some time the eruption builds up spatter resp.
 ash cones and may concentrate on one or some of them.
 Small fissure vents may not be easily discernible from the air, but the crater rows (see Laki) or the canyons (see Eldgjá) built up by some of them are.
Siju Cave is located in Meghalaya state near Naphak Lane and Simsang River game reserve.
 It is a limestone cave.
 The Cave is filled with water and is many kilometers long.
 It is considered as the third longest cave system in India.
 In 1927 it was found that the caves have a temperature of 21–26.4 °C.
A skyway, skybridge, or skywalk is a type of pedway consisting of an enclosed or covered footbridge between two or more buildings in an urban area.
 This protects pedestrians from the weather.
 In North America skyways are usually owned by businesses, and are therefore not public spaces (compare with sidewalk).
 However, in Asia, such as Bangkok's and Hong Kong's skywalks, they are built and owned separately by the city government, connecting between privately run rail stations or other transport with their own footbridges, and run many kilometers.
 Skyways usually connect on the first few floors above the ground-level floor, though they are sometimes much higher, as in Petronas Towers.
 The space in the buildings connected by skyways is often devoted to retail business, so areas around the skyway may operate as a shopping mall.
 Non-commercial areas with closely associated buildings, such as university campuses, can often have skyways and/or tunnels connecting buildings.
