Because the Earth is approximately spherical, it has total area , meaning that the solar radiation arriving at the top of the atmosphere, averaged over the entire surface of the Earth, is simply divided by four to get 340 W/m 2. This flattening is due to Earth’s rotational velocity – a rapid 1,674.4 km/h (1,040.4 mph) – which causes the planet to bulge at the equator. The total surface area of the world is 510.072 million sq km, land surface area comes up to 148.94 million sq km which is equal to 1.60317527 × 10^15 sq feet. A 1 m2 solar panel with an efficiency of 18% produces 180 Watts. square meter(m2) More SI units can be found here: List of SI Units. Mercury, Venus, Earth and Mars) it is the largest. Earth’s continents, on the other hand, cover the remaining 149 million km² (57.5 or million mi²). Assume the Earth has an albedo of 0, so that all the solar energy intercepted by the The earth is mostly blue because its large surface area of oceans. According to the 2004 Working Group of the International Earth Rotation and Reference Systems Service (IERS), Earth experiences a flattening of 0.0033528 at the poles. Then multiple your square metre measurement by 0.05 ie. This is true for other planets in the Solar System that have rapid rotations (like Jupiter and Saturn), and even stars like the rapidly-spinning Altair. Let’s see just how Earth stacks up against these other worlds…. Calculate the unknown defining side lengths, circumferences, volumes or radii of a various geometric shapes with any 2 known variables. The Earth is a distance d = 1.5 x 1011 m from the Sun.At that distance, the solar radiation flux F s is distributed uniformly over a sphere centered on the Sun with radius d. What is the solar radiation flux F s in W m-2? According to modern estimates, the surface area of the Earth is approximately 510 million square km (5.1 x 108 km2) or 196,900,000 square miles. It all starts with the Sun, where the fusion of hydrogen creates an immense amount of energy, heating the surface to around 6000°K; the Sun then radiates energy outwards in the form of ultraviolet and visible light, with a bit in the near infrared part of the spectrum. The remaining 71% is covered with water, mostly by oceans but also lakes, rivers and other fresh water, which together constitute the hydrosphere. Here’s What is the Diameter of Earth?, How Strong is the Force of Gravity on Earth?, How Much Does the Earth Way?, How Fast Does the Earth Rotate?, 1o Interesting Facts About Planet Earth, What is the Earth’s Average Temperature?, and Why Does the Earth Rotate? 70.8% of the world's surface is water, 29.2% is land-----1.60317527 × 1 000 000 000 000 000 (sq feet) / 6.48 billion = 22 984.5457 m2. And since 70% of the Earth’s surface is covered by water, that works out to 361 million km² (139.4 million mi²). 40 x 0.05 = 2m3 of product required for good surface coverage. Area scales as a distance squared. SDZ Shapes However, when compared to the gas giants (Jupiter, Saturn, Uranus and Neptune) it comes in dead last! oceans or continental crust). How Strong is the Force of Gravity on Earth? Our planet has 5 oceans and 7 continents, with most of the area … In gravity field the force is created by the weight of an object. The power density of the sun's radiation on the surface of the earth is approximately 1.4 kW/m 2.This value varies slightly throughout the year but by no more than 0.1 percent. Online calculators and formulas for a surface area and other geometry problems. 2 March 2015. And in the era of modern astronomy, improvements in instrumentation, methodology, and the ability to see Earth from space have certainly helped.
