Senegalia greggii. It is a large shrub or small tree growing to 10–15 m (33–49 ft) tall with a trunk up to 20–30 cm (7.9–11.8 in) diameter. The grey-green leaves are deciduous, and bipinnate, divided into 1-3 pairs of pinnae, each pinna 2–3 cm (0.79–1.18 in) long with 10-18 leaflets that are 3–6 mm (0.12–0.24 in).
The Great Basin Desert is part of the Great Basin between the Sierra Nevada and the Wasatch Range.The desert is a geographical region that largely overlaps the Great Basin shrub steppe defined by the World Wildlife Fund, and the Central Basin and Range ecoregion defined by the U.S. Environmental Protection Agency and United States Geological Survey.
[2] [5] For comparison, this is 10.7 °C (19.3 °F) colder than subliming dry ice (at sea level pressure). The elevation of the location is 3,488 meters (11,444 feet). Satellite measurements have identified even lower ground temperatures, with −93.2 °C (−135.8 °F) having been observed at the cloud-free East Antarctic Plateau on 10 August ...
A map of the Arctic. The red line is the 10 °C isotherm in July, commonly used to define the Arctic region; also shown is the Arctic Circle. The white area shows the average minimum extent of sea ice in summer as of 1975. [1] The climate of the Arctic is characterized by long, cold winters and short, cool summers.
s: A dry summer—the driest month in the high-sun half of the year (April to September in the Northern Hemisphere, October to March in the Southern Hemisphere) has less than 30 millimetres (1.18 in)/40 millimetres (1.57 in) of rainfall and has exactly or less than 1 ⁄ 3 the precipitation of the wettest month in the low-sun half of the year ...
However, all food webs eventually depend on plants, which are the primary producers. Coral reefs typically produce 5–10 grams of carbon per square meter per day (gC·m −2 ·day −1) biomass. [101] [102] One reason for the unusual clarity of tropical waters is their nutrient deficiency and drifting plankton. Further, the sun shines year ...

Total atmospheric mass is 5.1480×10 18 kg (1.135×10 19 lb), [42] about 2.5% less than would be inferred from the average sea level pressure and Earth's area of 51007.2 megahectares, this portion being displaced by Earth's mountainous terrain. Atmospheric pressure is the total weight of the air above unit area at the point where the pressure ...
