The marine biome Online exhibits : The world's biomes The marine biome Marine regions cover about three-fourths of the Earth's surface and include oceans, coral reefs, and estuaries. Marine algae supply much of the world's oxygen supply and take in a huge amount of atmospheric carbon dioxide. The evaporation of the seawater provides rainwater for the land. Oceans The largest of all the ecosystems, oceans are very large bodies of water that dominate the Earth's surface. The intertidal zone is where the ocean meets the land — sometimes it is submerged and at other times exposed, as waves and tides come in and out. The pelagic zone includes those waters further from the land, basically the open ocean. The benthic zone is the area below the pelagic zone, but does not include the very deepest parts of the ocean (see abyssal zone below). The deep ocean is the abyssal zone. Coral reefs Coral reefs are widely distributed in warm shallow waters.

The desert biome Online exhibits : The world's biomes The desert biome Deserts cover about one fifth of the Earth's surface and occur where rainfall is less than 50 cm/year. Although most deserts, such as the Sahara of North Africa and the deserts of the southwestern U.S., Mexico, and Australia, occur at low latitudes, another kind of desert, cold deserts, occur in the basin and range area of Utah and Nevada and in parts of western Asia. Most deserts have a considerable amount of specialized vegetation, as well as specialized vertebrate and invertebrate animals. Soils often have abundant nutrients because they need only water to become very productive and have little or no organic matter. There are relatively few large mammals in deserts because most are not capable of storing sufficient water and withstanding the heat. Desert biomes can be classified according to several characteristics. The seasons are generally warm throughout the year and very hot in the summer. Canopy in most deserts is very rare.
Blue Planet Biomes - Tundra Biome Did you know that the Arctic Tundra is the world's youngest biome? It was formed 10,000 years ago. Located at latitudes 55° to 70° North, the tundra is a vast and treeless land which covers about 20% of the Earth's surface, circumnavigating the North pole. It is usually very cold, and the land is pretty stark. Almost all tundras are located in the Northern Hemisphere. Tundra comes from the Finnish word "tunturia", which means a barren land. The main seasons are winter and summer. The Arctic tundra is also a windy place and winds can blow between 30 to 60 miles (48 to 97 kilometers) per hour. The tundra is basically like a desert when it comes to precipitation. There is barely any vegetation in the tundra, only about 1,700 different species, which isn't very much. Surprisingly there are animals in the tundra. The tundra is one of Earth's three major carbon dioxide sinks. The tundra is a very fragile environment. The tundra is not a cold and useless wasteland. by Whitney S. 2002

Interactive Climate Map Move cursor over rectangle to reveal climograph. Click rectangle to view information about the climate. Base map courtesy NOAA (Have patience while loading.) Australian Desert Plants Australian desert plants are clever survivors. Australia is the world’s driest inhabited continent with 70% of its landmass being deserts or semi-deserts. It is a harsh country for plants to live – it is extremely dry and it gets periods of drought that can last for years. It is extremely hot, with temperatures in 50s (°C) during the summer so if it does rain, evaporation is quick. The soils are ancient, rich in salt and extremely infertile. How can plants handle all this, and what plants are found in Australian deserts? Ausralian desert landscape, by AllPosters. Trees and Shrubs Some of the trees found in Australian deserts are the beautiful Ghost Gum (Corymbia sp.) which is almost iconic with its smooth silvery white bark; Mulga (Acacia aneura), Sandalwood (Santalum spicatum); Northern Cypress Pine (Callitris glaucophylla); Sandhill Wattle (Acacia ligulata); and Western Myall (Acacia papyrocarpa).

El sencillo experimento que demuestra el brutal efecto de la deforestación en las inundaciones El 'Día de la Sobrecapacidad de la Tierra' es el momento en el que el planeta ha agotado el 'presupuesto ecológico' de la Tierra para el 2018. Esto indica que la demanda de recursos naturales de la humanidad ha superado lo que los ecosistemas pueden renovar este año, según los datos de la organización científica Global Footprint Network ofrecidos por WWF. En el caso de España, el país entró en déficit ecológico el 11 de junio de 2018. Por ello, apunta que si todos los seres humanos viviesen como un español medio, consumirían el equivalente a 2,3 planetas por año. Para WWF, las personas tienen una oportunidad "crítica" de ahora a 2020 para acordar acciones y compromisos a escala global que reviertan la pérdida de naturaleza de cara a 2030.
Tropical Rainforest Plants in Australia There are many different kinds of tropical rainforest plants in Australia. Tropical rainforests are some of the species-richest ecosystems in the world. They grow in areas with the best conditions for plant growth in the world – with year-around warm temperatures, plenty of sunlight and rainfall. Poster by AllPosters. Despite the fact that their soils are poor on nutrients, they support so many species that they have been compared to coral reef ecosystems. Tropical Rainforest Plants: Tall Trees The most successful plants in the tropical rainforests are the tall trees. Tropical Rainforest Plants: Buttresses and Fig Trees These tall trees often have buttress roots, because the rainforest ground is often very moist, and just like mangroves, rainforest trees need to keep parts of their roots above the ground to get oxygen. Tropical Rainforest Plants: Different Types of Ferns Another group of common tropical rainforests plants are ferns.
Types of Weathering - Pass My Exams What is Weathering? Weathering is the name given to process by which rocks are gradually worn away by the action of the weather. There are three types of weathering. Physical weathering, Chemical weathering, and Biological weathering 1. Physical Weathering In physical weathering the rocks are broken down into smaller pieces, but the chemical composition of the rock remains the same. Temperature Change Hot temperatures can give rise to thermal expansion in rocks and cool temperatures can cause rocks to contract. Freeze-thaw Water expands when it freezes. The animation below shows the weathering action of water freezing and thawing in a rock. Wind, Rain and Waves Wind can carry small particles or sand and rocks such as in sandstorms in deserts. 2. Chemical weathering occurs when rocks are broken down by a chemical change. The degree of chemical weathering depends on the type of rock for example limestone is more readily chemically weathered than granite. 3.
Australian Animals | Facts | List | Native | Endangered | Introduced Why are Australian Animals Different? Unique and Strange Animals in Australia The reason Australia has such unique and unusual animals (and plants) is that it was isolated from the rest of the world for over 60 million years. Separated by vast oceans, Australian plants and animals evolved independently of those in other parts of the world. Interestingly many Australian fauna fill similar niches in the local environment to animals elsewhere in the world. Related Article: Unique Animals of Australia — Why are Australian Animals So Different? Native Australian Animals Which Animal is Native to Australia? Ever wondered what animals are really native to Australia? Generally speaking, it is any animal that has been in Australia before the arrival of humans. Australian Mammals Types of Native and Introduced Mammals in Australia There are three types of mammals in Australia. Monotremes first appeared between 145–99 million years ago and are the oldest type of Australian mammals.

L'emoció pintada El paisatge romàntic Painted emotions. Romantic landscape. Recognition of the Landscape as a first class genre of painting was one of the most important conquests of XIX century Art. Romanticism, through the works by Friedrich, Constable and Turner, gave us three different visions of nature, its perception and overall the expression of those emotions it can inspire Qui no ha sentit davant d’un bell paisatge una emoció molt fonda? Tot i així, hi va haver excepcions. Goethe va dir del romanticisme que era una malaltia. ■ La insignificança humana enfront de la creació Caspar David Friedrich, La gran tanca pròxima a Dresden, 1832. Caspar David Friedrich (Greifswald, Pomerània, Alemanya, 1774 – Dresden, Prússia, Alemanya, 1840) va descobrir en el món natural que l’envoltava l’alè de l’espiritualitat i el va dotar d’un profund sentiment que respirava religiositat.
