Why is it warmer in summer?
Peculiar enough the earth is over 3,000,000 miles closer to the sun during the northern winter than it is in summer. Yet it is much warmer in summer.
The reasons are not caused by different distances from the sun, but by the slant of the earth’s axis as it moves around the sun.
Scientists have learned that the equator of the earth is titled 23 degrees to the path of the earth around the sun.
As the earth moves around the sun, the earth’s axis always points in the same direction, towards the North Star. For this reason, during part of the year, the North Pole tilts towards the sun and part of the year away from it. When the North Pole is inclined towards the sun, the northern hemisphere has its winter. In the Southern Hemisphere, these seasons are reserved.
The contrast in weather with the seasons occurs due to the sun’s rays as they are more slanting in winter and less slanting in summer. Slanting rays produce less heat for two reasons. One is that they scatter their heat over a larger area of the earth’s surface. however, more of their heat is lost when passing through the atmosphere.
More factors such as primarily water, land, and altitude, help regulate the climate. Water has a stabilizing effect and helps prevent great changes in temperature. Land does not store up the heat (the way the ocean does), so big temperature changes can take place over large land areas. Air flows less dense with altitude and cannot absorb as much heat as at sea level. So the higher the altitude, the lower the temperature.
