A map of the Mid-Atlantic Ridge. The Mid-Atlantic Ridge (MAR) is a mid-ocean ridge, a divergent tectonic plate or constructive plate boundary located along the floor of the Atlantic Ocean, and part of the longest mountain range in the world.
Since the distances are so large, we usually express them in Astronomical Units (AU). (An AU is the average distance from Earth to the Sun, about 150 million kilometers or 93 million miles.) The table below lists the distance of each planet from the Sun in AU. (Numbers were taken from this page.)
The orbit of the Earth around the Sun is an ellipse. The distance is not fixed, but varies throughout its orbit. The average distance is about 150 million kilometers (149,597, â¦ 890 km) or about 93 million miles (92,955,820 mi.). The distance at perihelion is 147,098,290 km, the distance at aphelion is 152,098,232 km.e receive the same amount of solar radiation year-round. during the winter that radiation is spread over a larger surface and so it is less effective, during the summer the same radiation is on a smaller surface and so it is warmer.
