WebView the full answer. Final answer. Transcribed image text: Estimate the radius of the Earth (in km ). Question 2 Estimate the height of Earth's atmosphere (in km ). Question 3 Estimate the volume of Earth's oceans (in km3 ). Water has a density of ∼ 1gr/cm3 ∼ 1000 kg/m3. Estimate the mass of Earth's oceans (in kg ). WebThe Earth and the Moon form the Earth-Moon satellite system with a shared center of mass, or barycenter. This barycenter stays located at all times 1,700 km (1,100 mi) (about a quarter of Earth's radius) beneath the Earth's surface, making …
Getting distance between two points based on latitude/longitude
Earth radius (denoted as R🜨 or $${\displaystyle R_{E}}$$) 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 … See more Earth's rotation, internal density variations, and external tidal forces cause its shape to deviate systematically from a perfect sphere. Local topography increases the variance, resulting in a surface of profound complexity. Our … See more The following radii are derived from the World Geodetic System 1984 (WGS-84) reference ellipsoid. It is an idealized surface, and the … See more The Earth can be modeled as a sphere in many ways. This section describes the common ways. The various radii derived here use the notation and dimensions noted above for the … See more Earth's diameter is simply twice Earth's radius; for example, equatorial diameter (2a) and polar diameter (2b). For the WGS84 ellipsoid, that's respectively: • 2a = 12,756.2740 km (7,926.3812 mi), • 2b = 12,713.5046 km (7,899.8055 mi). See more Geocentric radius The geocentric radius is the distance from the Earth's center to a point on the spheroid surface at geodetic latitude φ: where a and b are, respectively, the equatorial radius … See more The mathematical expressions above apply over the surface of the ellipsoid. The cases below considers Earth's topography, above or below a See more The first published reference to the Earth's size appeared around 350 BC, when Aristotle reported in his book On the Heavens that mathematicians had guessed the circumference of the Earth to be 400,000 stadia. Scholars have interpreted Aristotle's figure to … See more WebOct 22, 2024 · The diameter of a circle is twice the radius, giving us a diameter for Earth of 12,756 km.
