Chapter 2: Solar Eneray. Seasons, and the Atmosphere What is the shape of Earth's orbit around the Sun? .What is perihelion? What is aphelion Most insolation is in the form of leaves Earth's system is in the form of (shortwave or longwave) radiation. Most of the energy t (shortwave or longwave) radiation. .What is the subsolar point? Between which latitudes does it migrate throughout the year What is the angular tilt of Earth's axis? Know the dates of the solstices and equinoxes and the location of the subsolar point at each. Als how to these correspond to seasons and daylengths in the northern and southern hemispheres? What is average atmospheric pressure at sea level? Does air pressure increase or decrease with altitude? · Know the ways the atmosphere is classified and the characteristics of each layer. You might be asked to label these. Classified by Composition: Heterosphere, Homos phere Classfed by tempe aiure Thermaosphere, Mesogphere, Stratosphere, Troposphere Classified by Function: lonosphere, Ozonosphere o What are the most abundant gases? » o What is the Normal Lapse Rate? o What does Anthropogenic mean? What is an inversion layer?Explanation / Answer
Answer (1) -Like all planets in our solar system, the Earth is in an elliptical orbit around our Sun. In Earth's case, its orbit is nearly circular, so that the difference between Earth's farthest point from the Sun and its closest point is very small.
Answer(2)- Earth's orbit is almost a perfect circle, so the difference between its distance to the Sun at aphelion and at perihelion is slight. Some planets have orbits that are more elongated; astronomers say their orbits have a greater "eccentricity", which is a technical term for how "stretched out" an orbit is.When the planet is closest to the Sun it is at Perihelion and when it is further away it is at Aphelion. The Perihelion of Earth is about 146 million km while the Aphelion is at 152 million km with average distance of 152 million km, also called the semi-major
Answer(3) -Insolation is the solar radiation that reaches the earth's surface. It is measured by the amount of solar energy received per square centimetre per minute.The Insolation received by the earth is in short waves forms and heats up its surface.
* most of the energy in the earth system is shortwave.Incoming ultraviolet, visible, and a limited portion of infrared energy(together sometimes called "shortwave radiation") from the Sun drive the Earth's climate system. Some of this incoming radiation is reflected off clouds, some is absorbed by theatmosphere, and some passes through to the Earth's surface.
Answer(4) The subsolar point on a planet is where its sun is perceived to be directly overhead (in zenith); that is where the sun's rays are hitting the planet exactly perpendicular to its surface. It can also mean the pointclosest to the sun on an object in space, even though the sun might not be visible. The December solstice occurs when the subsolar point is on the Tropic of Capricorn and the June solstice is at the instant when the subsolar point is on the Tropic of Cancer. The March and September equinoxes occur when the subsolar point crosses the equator.(21 June)
Answer(5)- Earth planet's axis of rotation is tilted at an angle of 23.5 degrees relative to our orbital plane – the plane of Earth's orbit around the sun.
