Esmeraldas–Pacific Colombia Mangroves
The Esmeraldas-Pacific Colombia mangroves (NT1409) is an ecoregion of mangrove forests along the Pacific coast of Colombia and Ecuador. It is threatened by human population growth, leading to over-exploitation for wood and clearance for farming and aquaculture. Geography Location Mangroves are found along the coast of Colombia and Ecuador from the Gulf of Tribugá in the north to Mompiche Bay in the south. Between these bays there are extensive stands of mangroves in the mouths of the San Juan River (Colombia), San Juan, Naya River, Naya, Guapi River, Guapi, Mira River (South America), Mira and Esmeraldas River, Esmeraldas rivers. The mangroves cover . The largest block is the almost continuous strip from the Mataje River to Chanzará bay near Guapi, Cauca, Guapi. In 1996 it was estimated that of mangroves were growing in the four Colombian Pacific coast departments. The mangroves border the Chocó–Darién moist forests ecoregion along most of the Pacific coast of Colombia. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Utría National Natural Park
The Utría National Natural Park () is a national park in the Chocó Department, Colombia. It contains diverse flora and fauna in a lush, mountainous rainforest environment with some of the highest rainfall in the world, at up to annually.

Chocó–Darién Moist Forests
The Chocó–Darién moist forests (NT0115) is a largely forested, tropical ecoregion of northwestern South America and southern Central America. The ecoregion extends from the eastern Panamanian province of Darién and the indigenous region of Guna Yala to almost the entirety of Colombia's Pacific coast, including the departments of Cauca, Chocó, Nariño and Valle del Cauca. This largely untouched, inaccessible expanse of jungle receives some of the planet's highest rates of precipitation, with the average rainfall measuring anywhere from 4,000 mm to 9,000 mm (around 13-30 ft) per year. Combined with high humidity and daily average temperatures of around 23.89 °C (75 °F), the foundation is set for a lush landscape brimming with species, harboring a huge wealth of plant, animal and fungal biodiversity. Many of the dominant tree species within the north of the ecoregion belong to such genera as the bongo ('' Cavanillesia''), wild cashew ('' Anacardium''), rubbe ...

Manabí Mangroves
The Manabí mangroves (NT1418) is an ecoregion along the Pacific coast of Ecuador. The mangroves serve important functions in the marine and terrestrial ecology. They have been severely degraded and fragmented, particularly in the northern region. Construction of shrimp farms caused much damage in the past, but is now banned. Sedimentation caused by overgrazing in higher lands is an issue, as are human activities such as port and highway construction, urbanization, waste disposal and so on. Geography Location The mangroves are found along the coast of Ecuador and cover an area of . There are two sub-regions. The Cojimíes sub-region in Esmeraldas Province lies between the Muisne River to the north and the town of Pedernales to the south. It transitions into the Western Ecuador moist forests ecoregion to the east. It contains a section around Muisne that fringes the Ensenada de Mompiche, and further south a larger section of mangroves around the estuary of the Mache River on ...

Gulf Of Panama Mangroves
The Gulf of Panama mangroves (NT1414) is an ecoregion along the Pacific coast of Panama and Colombia. The mangroves experience seasonal flooding with high levels of sediment, and occasional extreme storms or very low rainfall due to El Niño effects. They are important as a breeding or nursery area for marine species. Areas of the mangroves have been recognized as Important Bird Areas and Ramsar site, Ramsar wetlands. The ecoregion has been severely degraded by clearance of mangroves for agriculture, pasturage and shrimp farming, by urban pressure around Panama City, and by pollution related to the Panama Canal. Geography Location The Gulf of Panama mangroves (NT1414) extend from the Gulf of Parita past Chame Bay and Panama Bay to the Bay of San Miguel, also including patches on Bahía de Cupica and near Juradó.

Panama Bight Mangroves
Panama, officially the Republic of Panama, is a country in Latin America at the southern end of Central America, bordering South America. It is bordered by Costa Rica to the west, Colombia to the southeast, the Caribbean Sea to the north, and the Pacific Ocean to the south. Its capital and largest city is Panama City, whose metropolitan area is home to nearly half of the country's over million inhabitants. Before the arrival of Spanish colonists in the 16th century, Panama was inhabited by a number of different indigenous tribes. It broke away from Spain in 1821 and joined the Republic of Gran Colombia, a union of Nueva Granada, Ecuador, and Venezuela. After Gran Colombia dissolved in 1831, Panama and Nueva Granada eventually became the Republic of Colombia. With the backing of the United States, Panama seceded from Colombia in 1903, allowing the construction of the Panama Canal to be completed by the United States Army Corps of Engineers between 1904 and 1914.

Intertropical Convergence Zone
The Intertropical Convergence Zone (ITCZ , or ICZ), known by sailors as the doldrums or the calms because of its monotonous windless weather, is the area where the northeast and the southeast trade winds converge. It encircles Earth near the thermal equator though its specific position varies seasonally. When it lies near the geographic equator, it is called the near-equatorial trough. Where the ITCZ is drawn into and merges with a monsoon, monsoonal circulation, it is sometimes referred to as a ''monsoon trough'' (a usage that is more common in Australia and parts of Asia). Meteorology The ITCZ was originally identified from the 1920s to the 1940s as the ''Intertropical Front'' (''ITF''), but after the recognition in the 1940s and the 1950s of the significance of convergence zone, wind field convergence in tropics, tropical weather production, the term ''Intertropical Convergence Zone'' (''ITCZ'') was then applied. The ITCZ appears as a band of clouds, usually thunderstorms, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Limestone
Limestone is a type of carbonate rock, carbonate sedimentary rock which is the main source of the material Lime (material), lime. It is composed mostly of the minerals calcite and aragonite, which are different Polymorphism (materials science), crystal forms of calcium carbonate . Limestone forms when these minerals Precipitation (chemistry), precipitate out of water containing dissolved calcium. This can take place through both biological and nonbiological processes, though biological processes, such as the accumulation of corals and shells in the sea, have likely been more important for the last 540 million years. Limestone often contains fossils which provide scientists with information on ancient environments and on the evolution of life. About 20% to 25% of sedimentary rock is carbonate rock, and most of this is limestone. The remaining carbonate rock is mostly Dolomite (rock), dolomite, a closely related rock, which contains a high percentage of the mineral Dolomite (mine ...

Sandstone
Sandstone is a Clastic rock#Sedimentary clastic rocks, clastic sedimentary rock composed mainly of grain size, sand-sized (0.0625 to 2 mm) silicate mineral, silicate grains, Cementation (geology), cemented together by another mineral. Sandstones comprise about 20–25% of all sedimentary rocks. Most sandstone is composed of quartz or feldspar, because they are the most resistant minerals to the weathering processes at the Earth's surface. Like uncemented sand, sandstone may be imparted any color by impurities within the minerals, but the most common colors are tan, brown, yellow, red, grey, pink, white, and black. Because sandstone beds can form highly visible cliffs and other topography, topographic features, certain colors of sandstone have become strongly identified with certain regions, such as the red rock deserts of Arches National Park and other areas of the Southwestern United States, American Southwest. Rock formations composed of sandstone usually allow the p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lutite
Lutite is old terminology, which is not widely used, by Earth scientists in field descriptions for fine-grained, sedimentary rocks, which are composed of silt-size sediment, clay-size sediment, or a mixture of both. When mixed with water lutites often disintegrate into mud. Because this is a field term, there is a lack of any precise definition for it based upon specific grain-size characteristics. Lutites include a variety of fine-grained sedimentary rocks, including calcisiltite, calcilutite, claystone, mudstone, shale, and siltstone. It is equivalent to the term mudstone and the Greek-derived term pelite A pelite () or metapelite is a metamorphism, metamorphosed fine-grained sedimentary rock, i.e. mudstone or siltstone. The term was earlier used by geologists to describe a clay-rich, fine-grained clastic sediment or sedimentary rock, i.e. mud or ....Potter, P.E., J.B. Maynard, and P.J.
