Document Summary
Read up on the scientific method, earth systems. Polar circumference of the earth 24,860 mi equatorial circumference 24,902 mi equatorial diameter 7,926 mi polar diameter 7,900 mi. Earth"s or(cid:271)it around the sun is ellipti(cid:272)al, travels through the plane of the e(cid:272)lipti(cid:272) In boone, we are rotating at about 850 mph light year the distance that light travels in 1 year light speed 300,000 km/s or 186,000/s. Solar energy is radiant energy from the sun helium and emit a large amount of energy. Solar radiation occupies a portion of the electromagnetic spectrum of radiant energy, this energy travels. Black body radiation law- bodies radiate energy at (peak intensity) a wavelength inversely proportional. Insolation- incoming solar radiation at short wavelengths, mostly visible. Our atmosphere is transparent to short wave energy, but opaque to long wave. Insolation at the top of the atmosphere is expressed as the solar constant 1372w/ m squared or. Perihelion- closest on jan 3 to the sun.
