The hydrosphere is defined as the total mass of water found on, beneath, and above the surface of a planet, minor planet, or natural satellite. Despite the fact that the Earth’s hydrosphere has been existing for roughly 4 billion years, it is still changing shape. This is created by seafloor spreading and continental drift, which […]
The Arctic Ocean is the smallest and shallowest of the world’s five major oceans. It spans an area of approximately 14,060,000 km2 (5,430,000 sq mi) and is also known as the coldest of all the oceans. It has been described approximately as an estuary of the Atlantic Ocean. It is also seen as the northernmost
The Caspian Sea is the world’s largest inland body of water. It covers 371,000 km2 (143,000 sq mi) and has a volume of 78,200 km3 (19,000 cu mi). It has a salinity of approximately 1.2% (12 g/l), about a third that of average seawater.
Europe is a continent that lies fully in the Northern Hemisphere and primarily in the Eastern Hemisphere. It consists of the westernmost peninsulas of Eurasia’s continental landmass, shares the continental landmass of Afro-Eurasia with both Asia and Africa, and is bounded by the Arctic Ocean to the north, the Atlantic Ocean to the west, the
The Atlantic Ocean is the second-largest of the world’s oceans, with an area of about 106,460,000 km2 (41,100,000 sq mi). It covers approximately 20 percent of Earth’s surface and about 29 percent of its water surface area. It is known to separate the “Old World” of Europe and Asia from the “New World” of the Americas in the European perception of the World.
Earth is the third planet from the Sun and the only known celestial object capable of harboring and supporting life. Land, which consists of continents and islands, covers 29.2 percent of the Earth’s surface. The remaining 70.8 percent is covered by water, largely in the form of oceans, seas, gulfs, and other salt-water bodies, but also
An estuary is a partially enclosed coastal body of brackish water with one or more rivers or streams flowing into it, and with a free connection to the open sea. Estuaries form a transition zone between river environments and maritime environments and are an example of an ecotone. Estuaries are subject both to marine influences such as tides, waves, and the influx of saline
The ocean (also the sea or the world ocean) is the body of salt water that covers approximately 70.8% of the surface of Earth and contains 97% of Earth’s water. Another definition is “any of the large bodies of water into which the great ocean is divided”. Separate names are used to identify five different areas of the ocean: Pacific (the largest) Atlantic, Indian, Southern (Antarctic), and Arctic (the smallest). Seawater covers approximately 361,000,000 km2 (139,000,000 sq mi) of the
Fallingwater is a house designed by the architect Frank Lloyd Wright in 1939 in the Laurel Highlands of southwest Pennsylvania, about 70 miles (110 km) southeast of Pittsburgh. The house was built partly over a waterfall on Bear Run in the Mill Run section of Stewart Township, Fayette County, Pennsylvania, located in the Laurel Highlands of the Allegheny Mountains. The house was designed as a weekend home for Liliane
The Po is the longest river in Italy. It is a river that flows eastward across northern Italy starting from the Cottian Alps. The Po flows either 652 km (405 mi) or 682 km (424 mi) – considering the length of the Maira, a right bank tributary. The headwaters of the Po are a spring seeping from a stony hillside at Pian del Re,
