how much does the earth
Weigh
Answers
Answer:
The Karman line, 60 miles above Earth's surface, defines the official boundary between our atmosphere and the edge of space, so that is what we have to weigh. Sea level atmospheric pressure is 15 pounds per square inch, meaning every square inch of our planet's surface has 15 pounds of air above it.
Answer:
Earth weighs about 13,170,000,000,000,000,000,000,000 pounds (or 5,974,000,000,000,000,000,000,000 kilograms). Since Earth is too big to be placed on a scale, scientists use mathematics and the laws of gravity to figure out Earth's weight.
The sky is blue due to a phenomenon called Raleigh scattering. This scattering refers to the scattering of electromagnetic radiation (of which light is a form) by particles of a much smaller wavelength. These shorter wavelengths correspond to blue hues, hence why when we look at the sky, we see it as blue.
