The ocean is the body of salt water that covers approx. 70.8% of Earth. [8] In English, the term ocean also refers to any of the large bodies of water into which the world ocean is conventionally divided. [9] The following names describe five different areas of the ocean: Pacific, Atlantic, Indian, Antarctic/Southern, and Arctic.
Why is the Sun's corona so much hotter than the Sun's surface? (more unsolved problems in astronomy) The temperature of the photosphere is approximately 6,000 K, whereas the temperature of the corona reaches 1,000,000–2,000,000 K. The high temperature of the corona shows that it is heated by something other than direct heat conduction from the photosphere. It is thought that the energy ...

Because the oceans that cover roughly 70.8% of the area of Earth reflect blue light, Earth appears blue from space, and is often referred to as the blue planet and the Pale Blue Dot. Liquid freshwater like lakes and rivers cover about 1% of Earth's surface and altogether with Earth's ice cover, Earth's surface is 75% water by area.
Pluto (bottom left) compared in size to the Earth and the Moon. Pluto's diameter is 2 376.6 ± 3.2 km and its mass is (1.303 ± 0.003) × 10 22 kg, 17.7% that of the Moon (0.22% that of Earth). Its surface area is 1.774 443 × 10 7 km 2, or just slightly bigger than Russia or Antarctica.
Total area is 17,035,650 km2 when including Siberia or North Asia (13,083,100 km2). [3] ^ Includes Crimea (26,945 km2) and other territory annexed by Russia but internationally recognized as part of Ukraine. [4] ^ Mainland France (535,261 km2) and Corsica (8,680 km2) comprise European France or Metropolitan France.
The US has the 2nd largest Exclusive Economic Zone of 11,351,000 km 2 (4,383,000 sq mi). By total area ( water as well as land), the United States is either slightly larger or smaller than the People's Republic of China, making it the world's third or fourth-largest country.
