Which model shows an equinox, and which shows a solstice? explain your reasoning.

The first model is an equinox and the second model is a solstice. An equinox is an event that happens twice a year. The word "equinox" actually comes from a Latin term meaning "equal night." That's because during an equinox, it's believed that all areas. A solstice is an event that also happens twice a year. The word "solstice" comes from the Latin word "sol" meaning sun, and "sistere" meaning to make stand. The way we understand it literally is that it describes the moment that the sun reaches its northern or southernmost point. In essence, the sun is standing. More specifically, it occurs when the Sun's path is farthest from the equator. In the Northern Hemisphere the summer solstice happens in June, and in southern hemisphere, the solstice happens in December — hence why the seasons are reversed in each hemisphere. So the winter solstice (Dec. 21) is the shortest day of the year while the summer solstice (Jun. 21) is the longest day of the year. of the Earth's surface experience an equal amount of daylight and darkness — 12 hours each. That's easy to remember, right? In autumn, the equinox (Sept. 21) is in the northern hemisphere, and in spring, the equinox (Mar. 20 or Mar. 21 — it varies from year to year) is in the southern hemisphere. So, the equinoxes are the times of the year where the part of the Earth closest to the sun is the exact equator. So when everything is aligned, everywhere from the North Pole to the South Pole will get the same amount of sunlight — but only on those two, equinoxes, in September and March — they exact dates of which, might change up to three days, depending on year. The biggest difference between the equinox and the solstice is that a solstice is the point during the Earth's orbit around the sun at which the sun is at its greatest distance from the equator, while during an equinox, it's at the closest distance from the equator. Because of this, one solstice is an extremely long day, and the other is an extremely short day. Comparatively, during an equinox, the days and nights are equal lengths. That's the easiest way to describe our experience on with the solstices and equinoxes. While scientifically speaking, their effects might be greater, all we really notice from Earth is the amount of daylight we receive. And even that, since the effects are so slight, might not be that noticeable.

Explanation:

First model depicts the equinox whereas second model depicts solstice. Both events take place twice in a year and the reasons are:

Equinox means equal length of day and night, it take place when the sun is above the equator i.e. over zero degree on 21st march and 21st September.

Solstice means sun is standing, it take place when the sun is standing at Tropic of cancer and Tropic of Capricorn, two solstice are:

ionic bonds are two oppositely charged ions that attract. a sodium ion has a 1 positive charge; a chloride ion has a 1 negative charge. sodium and chloride have oppostive charged ions that attract which forms an ionic bond. a chemical bond formed when two atoms share electrons is called
