How does insolation change with increasing latitude

The geometric relationship shown in the previous figure applies to the entire Earth because of its spherical shape. The figure to the right shows how equal rays of solar energy strike different parts of the Earth, varying in angle of incidence from a position along the equator to ones nearer the poles. Each orange bar is of equal width and represents insolation equal to the solar constant. Some insolation strikes the outside of Earth's atmosphere perpendicularly, like a light pointed directly toward a surface.

In the mid-latitude regions north or south of the equator, insolation strikes the outside of Earth's atmosphere at a slightly oblique angle and is distributed over a wider area than at the equator.

Thus the amount of energy is distributed over a larger area compared to the equator, and the energy per area is less. In contrast to the equator, insolation arriving above polar regions strikes Earth's atmosphere at a very low angle of incidence, much lower than the angled light in the figure above. As a result, the energy represented by the ray the solar constant spreads over a relatively large surface area the small red box. In addition to these geometric effects, the atmosphere further influences the amount of insolation that reaches Earth's surface, depending on the angle of the incoming energy.

As shown in this figure, energy that comes directly down at the surface, like a vertical light, passes through the atmosphere in the shortest distance possible. Some energy is reflected or absorbed by the atmosphere. Energy coming at a lower angle of incidence must pass through more of the atmosphere to reach the surface. This increases the amount of atmospheric attenuation and causes less energy to reach the surface. This is a further reason why early morning and late afternoon sunlight does not feel as intense as that at noon, and why the winter Sun, which is low in the sky, does not feel as intense as the summer Sun, which is higher in the sky.

When viewing the entire Earth, latitude strongly influences the severity of atmospheric attenuation. What layer of the sun moves heat from the radiative layer to the photosphere.

How do scientists study the Layers of the Earth. What type of volcanoes formed the Hawaiian islands. Which type of fault is the San Andreas fault. Which type of volcano produces volcanic bombs.

What explains the variation of incoming solar radiation by latitude? Sunlight filters through a thick wedge of atmosphere, making the sunlight much less intense. This means that the insolation is more concentrated near the equator and weaker near the poles.

The albedo effect on sea. Albedo is an expression of the ability of surfaces to reflect sunlight heat from the sun. Light-coloured surfaces return a large part of the sunrays back to the atmosphere high albedo. Dark surfaces absorb the rays from the sun low albedo.

In this case, summer is defined as the period during which daily average insolation intensity exceeds a specified threshold. The summer energy is generally insensitive to precession because, for example, just when perihelion occurs at summer solstice, summertime is shortest. Located between about 50 and 80 kilometers 31 and 50 miles above Earth's surface, the mesosphere gets progressively colder with altitude.

In fact, the top of this layer is the coldest place found within the Earth system, with an average temperature of about minus 85 degrees Celsius minus degrees Fahrenheit. The particles in the exosphere are moving very quickly, so the temperature there is quite hot. Since the "air" is so thin in the exosphere - it is almost a vacuum - there are very, very few particles.

We feel warmth when particles hit our skin and transfer heat energy to us. If we subdivide the Earth based on rheology, we see the lithosphere, asthenosphere, mesosphere, outer core, and inner core. However, if we differentiate the layers based on chemical variations, we lump the layers into crust, mantle, outer core, and inner core. How insolation varies with latitude?
