Q:Information:  - In geology, a supercontinent is the assembly of most or all of Earth's continental blocks or cratons to form a single large landmass. However, the definition of a supercontinent can be ambiguous. Many earth scientists, such as P.F. Hoffman (1999), use the term "supercontinent" to mean "a clustering of nearly all continents". This definition leaves room for interpretation when labeling a continental body and is easier to apply to Precambrian times. Using the first definition provided here, Gondwana (a.k.a. Gondwanaland) is not considered a supercontinent, because the landmasses of Baltica, Laurentia and Siberia also existed at the same time but physically separate from each other. The landmass of Pangaea is the collective name describing all of these continental masses when they were in proximity to one another. This would classify Pangaea as a supercontinent. According to the definition by Rogers and Santosh (2004), a supercontinent does not exist today. Supercontinents have assembled and dispersed multiple times in the geologic past (see table). The positions of continents have been accurately determined back to the early Jurassic. However, beyond , continental positions are much less certain.  - Isalo National Park is a National Park in the Ihorombe Region of Madagascar . The park is known for its wide variety of terrain , including sandstone formations , deep canyons , palm - lined oases , and grassland . The closest town is Ranohira , and the closest cities are Toliara and Ihosy .  - The Indian Ocean is the third largest of the world's oceanic divisions, covering (approximately 20% of the water on the Earth's surface). It is bounded by Asia on the north, on the west by Africa, on the east by Australia, and on the south by the Southern Ocean or, depending on definition, by Antarctica. It is named after the country of India. The Indian Ocean is known as "Ratnkara", ""the mine of gems"" in ancient Sanskrit literature, and as "Hind Mahsgar", ""the great Indian sea"", in Hindi.  - A biodiversity hotspot is a biogeographic region with significant levels of biodiversity that is under threat from humans. Norman Myers wrote about the concept in two articles in The Environmentalist (1988), & 1990 revised after thorough analysis by Myers and others in Hotspots: Earths Biologically Richest and Most Endangered Terrestrial Ecoregions and a paper published in the journal "Nature"  - Grasslands are areas where the vegetation is dominated by grasses (Poaceae), however sedge (Cyperaceae) and rush (Juncaceae) families can also be found. Grasslands occur naturally on all continents except Antarctica. Grasslands are found in most ecoregions of the Earth. For example, there are five terrestrial ecoregion classifications (subdivisions) of the temperate grasslands, savannas, and shrublands biome (ecosystem), which is one of eight terrestrial ecozones of the Earth's surface.  - Sandstone (sometimes known as arenite) is a clastic sedimentary rock composed mainly of sand-sized minerals or rock grains.  - A census is the procedure of systematically acquiring and recording information about the members of a given population. It is a regularly occurring and official count of a particular population. The term is used mostly in connection with national population and housing censuses; other common censuses include agriculture, business, and traffic censuses. The United Nations defines the essential features of population and housing censuses as "individual enumeration, universality within a defined territory, simultaneity and defined periodicity", and recommends that population censuses be taken at least every 10 years. United Nations recommendations also cover census topics to be collected, official definitions, classifications and other useful information to co-ordinate international practice.  - India, officially the Republic of India ("Bhrat Gaarjya"), is a country in South Asia. It is the seventh-largest country by area, the second-most populous country (with over 1.2 billion people), and the most populous democracy in the world. It is bounded by the Indian Ocean on the south, the Arabian Sea on the southwest, and the Bay of Bengal on the southeast. It shares land borders with Pakistan to the west; China, Nepal, and Bhutan to the northeast; and Myanmar (Burma) and Bangladesh to the east. In the Indian Ocean, India is in the vicinity of Sri Lanka and the Maldives. India's Andaman and Nicobar Islands share a maritime border with Thailand and Indonesia. Its capital is New Delhi; other metropolises include Mumbai, Kolkata, Chennai, Bangalore, Hyderabad and Ahmedabad.  - Ihosy is a city (commune urbaine) with 16990 inhabitants (2004) in Ihorombe Region in central south Madagascar.   - Shrubland, scrubland, scrub or brush is a plant community characterised by vegetation dominated by shrubs, often also including grasses, herbs, and geophytes. Shrubland may either occur naturally or be the result of human activity. It may be the mature vegetation type in a particular region and remain stable over time, or a transitional community that occurs temporarily as the result of a disturbance, such as fire. A stable state may be maintained by regular natural disturbance such as fire or browsing. Shrubland may be unsuitable for human habitation because of the danger of fire. The term "shrubland" was first coined in 1903.  - The Cyperaceae are a family of monocotyledonous graminoid flowering plants known as sedges, which superficially resemble grasses and rushes. The family is large, with some 5,500 known species described in about 90 genera, the largest being the "Carex" genus of "true sedges" with over 2,000 species. These species are widely distributed, with the centers of diversity for the group occurring in tropical Asia and tropical South America. While sedges may be found growing in almost all environments, many are associated with wetlands, or with poor soils. Ecological communities dominated by sedges are known as sedgelands.  - Arenite (Latin "Arena", sand) is a sedimentary clastic rock with sand grain size between 0.0625 mm (0.00246 in) and 2 mm (0.08 in) and contain less than 15% matrix. The related adjective is "arenaceous". The equivalent Greek-derived term is psammite, though this is more commonly used for metamorphosed sediments.  - Poaceae or Gramineae is a large and nearly ubiquitous family of monocotyledonous flowering plants known as grasses. Poaceae includes the cereal grasses, bamboos and the grasses of natural grassland and cultivated lawns (turf) and pasture. Grasses have stems that are hollow except at the nodes and narrow alternate leaves borne in two ranks. The lower part of each leaf encloses the stem, forming a leaf-sheath. With ca 780 genera and around 12,000 species, Poaceae are the fifth-largest , following the Asteraceae, Orchidaceae, Fabaceae and Rubiaceae.  - Ihorombe is a region in Madagascar. It borders Haute Matsiatra region in north, Atsimo-Atsinanana in east, Anosy in south and Atsimo-Andrefana in west. The capital is Ihosy and the population was estimated to be 312,307 in 2013. The area of Ihorombe is and it has one of the lowest population densities of the Malagasy regions.  - An island country is a country whose primary territory consists of one or more islands or parts of islands. As of 2011, 46 (approximately 24%) of the 193 UN member states are island countries.  - The World Commission on Protected Areas (WCPA) is one of six commissions of the IUCN (World Conservation Union). WCPA is the world's premier network of protected area expertise. It is administered by IUCN's Global Protected Areas Programme and has over 2,400 members, spanning 140 countries.  - Atsimo-Andrefana is a region of Madagascar. It borders Menabe in north, Amoron'i Mania and Haute Matsiatra in northeast, Ihorombe and Anosy in east and Androy in southeast. The capital is Toliara and the population was estimated to be 1,316,756 in 2013. Atsimo Andrefana is geographically the largest of all Malagasy regions with an area of .  - A national park is a park in use for conservation purposes. Often it is a reserve of natural, semi-natural, or developed land that a sovereign state declares or owns. Although individual nations designate their own national parks differently, there is a common idea: the conservation of 'wild nature' for posterity and as a symbol of national pride. An international organization, the International Union for Conservation of Nature (IUCN), and its World Commission on Protected Areas, has defined "National Park" as its "Category II" type of protected areas.  - The Malagasy Republic was a state situated in Southeast Africa. It was established in 1958 as an autonomous republic within the newly created French Community and existed until the proclamation of the Democratic Republic of Madagascar in 1975.  - Ranohira is a town and commune in Madagascar. It belongs to the district of Ihosy, which is a part of Ihorombe Region. The population of the commune was estimated to be approximately 6,000 in 2001 commune census.  - Haute Matsiatra is a region in Madagascar. It borders Amoron'i Mania region in north, Vatovavy-Fitovinany in east, Ihorombe in south and Atsimo-Andrefana in west. The capital of the region is Fianarantsoa, and the population was estimated to be 1,131,700 in 2014. The area is .  - Madagascar, officially the Republic of Madagascar, and previously known as the Malagasy Republic, is an island country in the Indian Ocean, off the coast of Southeast Africa. The nation comprises the island of Madagascar (the fourth-largest island in the world), and numerous smaller peripheral islands. Following the prehistoric breakup of the supercontinent Gondwana, Madagascar split from the Indian peninsula around 88 million years ago, allowing native plants and animals to evolve in relative isolation. Consequently, Madagascar is a biodiversity hotspot; over 90% of its wildlife is found nowhere else on Earth. The island's diverse ecosystems and unique wildlife are threatened by the encroachment of the rapidly growing human population and other environmental threats.
