Most water in Earth's atmosphere and crust comes from saline seawater, while fresh water accounts for nearly 1% of the total. The vast bulk of the water on Earth is saline or salt water, with an average salinity of 35‰ (or 3.5%, roughly equivalent to 34 grams of salts in 1 kg of seawater), though this varies slightly according to the amount of runoff received from surrounding land.
Antarctica provides the water hemisphere with the majority of Earth's ice. Most of the Pacific Ocean and the Indian Ocean, and the whole Southern Ocean, are in the water hemisphere. The water hemisphere is approximately 89 percent water (almost all pertaining to the World Ocean), 6 percent dry land and 5 percent polar ice cap.
Earth radius (denoted as R 🜨 or ) is the distance from the center of Earth to a point on or near its surface. Approximating the figure of Earth by an Earth spheroid , the radius ranges from a maximum of nearly 6,378 km (3,963 mi) ( equatorial radius , denoted a ) to a minimum of nearly 6,357 km (3,950 mi) ( polar radius , denoted b ).
Earth is rounded into an ellipsoid with a circumference of about 40,000 km. It is the densest planet in the Solar System. Of the four rocky planets, it is the largest and most massive. Earth is about eight light-minutes away from the Sun and orbits it, taking a year (about 365.25 days) to complete one revolution.
(110–210 Earth radii) 6.36×10 6 –1.27×10 7: 6.80–7.10: The space dominated by Earth's magnetic field and its magnetotail, shaped by the solar wind. Earth's orbit: 299.2 million km 2 AU: 2.99×10 8: 8.48: The average diameter of the orbit of the Earth relative to the Sun. Encompasses the Sun, Mercury and Venus. Inner Solar System ~6.54 AU
What the average American pays for a typical water bill is around $39.16 per month. On average, the water bill for family is three times higher than that of a single-person household.
Relative masses of the Solar planets. Jupiter at 71% of the total and Saturn at 21% dominate the system. Relative masses of the solid bodies of the Solar System. Earth at 48% and Venus at 39% dominate. Bodies less massive than Pluto are not visible at this scale. Relative masses of the rounded moons of the Solar System.
Measured around the equator, it is 40,075.017 km (24,901.461 mi). Measured passing through the poles, the circumference is 40,007.863 km (24,859.734 mi). [1] Measurement of Earth's circumference has been important to navigation since ancient times. The first known scientific measurement and calculation was done by Eratosthenes, by comparing ...
