The discrepancy due interpolations appears so large and we remedy the figure by ratio and proportion.

3.6 OTHER NATURAL SOURCES OF HEAT
3.6.1 HEAT FROM THE INTERIOR OF THE EARTH
The interior or core of the earth is made up of molten metals to include heavy metals such as isotopes of Uranium, Radium, and Plutonium, which by themselves contain their isotopes and emits radiant particles that produces heat. According to some scientists, the soil structure that make up the earth’s outer crust emit one calorie per 10 M2 per second as attributed to the decaying isotopes at earth’s interior together with the residual heat that has been trapped within for 4.5 billion years ago.
Average Diameter of earth = (12,756,300 M + 12,713,822)/2
= 12,735,061M
Earth’s Surface area = (6,367,530.5 M)2 (3.141592654)2
= 400,167,499,248,166 M2

If it were not for the heat that was trapped inside the earth’s core and continuous emission of radio-active particles from the isotopes of metallic elements that comprise the core of the earth, the bottom of the ocean at the depth of 5,000 M to 10,000 M would be made up of ice. Even with the emission of 1,200 Calories/ Km2/Sec. the average temperature at the bottom of deep ocean approaches 0 0C or 273 0K. The existence of Glaciers, Hot Springs and certain spots with potentials of being developed into Geothermal Plants are evidences of enormous heat present within the interior of the earth. These smoke-like or steam emitting spots are found in areas where there are crevices on the rock structures similar to fault line that serve as passage of steam to escape.
Interior of the Sun
Regions of the Sun include the core, radiation zone, convection zone, and photosphere. Gases in the core are about 150 times as dense as water and reach temperatures as high as 16 million degrees C (29 million degrees F). The Sun’s energy is produced in the core through nuclear fusion of hydrogen atoms into helium. In the radiation zone, heat flows outward through gases that are about as dense as water. The radiation zone is cooler than the core, about 2.5 million degrees C (4.5 million degrees F). In the convection zone, churning motions of the gases carry the Sun’s energy further outward. The convection zone is slightly cooler, about 2 million degrees C (3.6 million degrees F), and less dense, about one-tenth as dense as water. The photosphere is much cooler, about 5500° C (10,000° F) and much less dense, about one-millionth that of water. The turbulence of this region is visible from earth in the form of sunspots, solar flares, and small patches of gas called granules.

3.6.2 REFLECTED HEAT FROM THE ATMOSPHERE
During the daytime, the temperature of the atmosphere is usually lower than the temperature of the ground. While both bodies emit radiant heat upon each other, the prevailing flow of heat is from the ground towards the atmosphere. It is in the same manner what happens during nighttime whereby it is the ground that imparts heat into the atmosphere by virtue of the fact that during daytime the ground absorbs heat that raises its temperature much higher than that of the atmosphere.
While it is the ground that always transmits radiant heat into the atmosphere, such rate of heat transfer is lower during the daytime because the temperature gradient between the two bodies is likewise lower.
When radiant energy penetrates the atmosphere and hits the ground, the ground gains about 3,102,975 Cal/M2 during the daytime which it emits during the 12 hour period at nighttime. During the daytime, heat is continuously absorbed and being emitted at the same time but absorption is greater than emission and the gradient between the two builds up the temperature.
During the daytime, on the other hand, the atmosphere continues to absorb heat directly from the sun while at the same time emits radiant energy into the upper layer of atmosphere and into the outer space. Part of the residual heat that the upper layer of atmosphere holds is radiated back towards the ground level. The gradient between what is absorbed and what is emitted builds up the temperature of the atmosphere during which it totally emits during nighttime.
3.6.3 EMISSION OF STORED HEAT FROM THE GROUND/WATER
It has been established that the heat that is absorbed by the ground material components of the earth during day time and being released during nighttime amounts to 3,102,975 Cal/M2/day in Metro Manila, Philippines. What is absorbed by the ground material component of the earth during the day consists of 28.44% of the total heat radiation received by the earth from the sun. Assuming that the same amount of heat is absorbed by the ground material component is the same all throughout the facial area of the earth, such total heat being absorbed is equivalent to the heat if and when 102,384 KM3 of gasoline is burned.
If the sunshine during bright summer day is directed to pure soil structure that is without any buffer or shades, the thickness of the earth materials that is affected by heat absorption is up to 30.646 centimeters. The surface temperature of the ground will rise from 300C to 450C or the average temperature of 37.50C.
The vegetative portion of the earth surface however,
Weight of soil = 0.30 M x 1.0 M2 x 2.7582 Tons/M3
= 0.82746 Tons/M2/day
Heat absorbed = 827,460 Gm (0.5 Cal/Gm/0C) (7.50C)
= 3,102,975 Cal/M2/day
The amount of heat that is absorbed every day is being emitted to outer space and the rest being absorbed by the atmosphere within the 24 hour period to establish thermal equilibrium. If not, the ground soil will eventually be red hot.
In the case of sea and ocean waters, a rough estimate is arrived at by the assumption that the temperature of water up to the depth of 200 Cm increased by 0.02 0C to 3.02 0C for a total absorption of 3,500,000 Cal/M2/day.
Since that the above figures refers only to a particular area near the equator, we may use the same figure provided that solar radiation must refer to the facial area of the earth instead of the ground surface area.

At nighttime, the temperature of the ground is higher than that of the atmosphere so that the flow of heat is from the ground to the atmosphere despite the fact that both bodies of the atmosphere and ground emit radiant heat upon each other.
From the early morning to late in the afternoon the ground absorbs 3,102,924.48 Calories to gain an average temperature from 300C to 37.50C and radiates the same amount of heat during nighttime to reduce its average temperature from 37.50C back to 300C. On the other hand, the atmosphere absorbs 4,975,110.00 Calories/M2/day to gain the rise in temperature from 200C to 300C during the daytime and radiates the same amount of heat to return its temperature from 300C to 200C during nighttime.
During the daytime, the ground radiates 1,272,714 Calories directly into the Outer Space and retains 3,102,924.48 Cal/M2/day out of 4,375,638.48 Calories it has absorbed from the sun during the day. During nighttime, the ground radiates 1,323,308.74 Calories directly into outer space and pass on 1,779,615.74 Calories into the Atmosphere.
