The Chicken-on-a-Bad-Rotisserie Effect
Besides the Earth rotating around its tilted axis, it is also revolving around the Sun. Here, again, we see what seems like a mistake in nature. The orbit of the Earth around the Sun is not a regular circle. It is an ellipse. The orbit is elongated like a stretched-out elastic band. This means that at some times of the year, the Earth is closer to the Sun than at other times. Physicists can explain why this happens; all we need to know is that it happens.
The Earth is closest to the Sun around June & December and furthest around March & September. The advantage of this elongated orbit is that, at some point, the Earth is too close to the Sun and more energy is absorbed from the Sun. Then, at

The major convection currents that the rising heat would cause would lead to severe weather conditions.
The hot air would rise to very high altitudes and fan out north and south. Cool air would sweep toward the Equator from the Poles. This cycle would have caused the polar ice caps to melt much sooner. There would probably be no ice at the North or South Poles by now.
In the no-axis-tilt scenario, rainfall would probably only fall between the 15° to 40° latitudes. It would be at these latitudes that the warm Equatorial air would mingle with the cool, polar air to cause rain. It would be difficult to sustain conditions where snow could be created.
The 23° axis tilt makes our current conditions possible. However, the fact that deserts form along the Tropics of Cancer and Capricorn suggests the instability of our climactic condition, and is probably unsustainable into perpetuity.
The presence of vast quantities of water on Earth is both a saving grace and a curse. It is a saving grace in that there will be evaporation as long as the Sun shines. The evaporation will most likely cause rainfall at some points on land. The rainfall will continue to sustain life on
3. Set up Gizmo: Click Reset, and turn on Show axis. Earth’s axis is an imaginary line that connects the North Pole to the South Pole. Earth spins around its axis, which is tilted relative to Earth’s orbit. Click Earth axis angle to set the axis angle to a realistic 23°.
This study recorded the position of the Sun over the course of a day, on three different occasions each one month apart. Then compare how the daily motion of the Sun changes throughout the course of a year. To measure the course of the Sun a roofing nail is placed on a paper and the end of the shadow is recoded over the length of the day. Starting the recording at approximately 10am and ending around 6pm.
These are called warming, or cooling periods. Currently earth is in a warming period, it’s natural. We have had 5 warming periods already and they go way back in time. So far the one we are in right now, is the only one that has involved humans. The evidence in graphs can prove that there has only been one warming period with humans.Our earth didn’t just start changing it’s climate.Climate change has been happening for millions, even billions, of years. It’s not important to us, we shouldn’t be worrying. Even scientists know this, “The world's climate has been changing for the past 20,000 year.” It’s most likely, been happening for even longer than this time. We aren’t the only things that contribute to climate change, theres tons of other things that emit carbon and other gases into the atmosphere..“The change in the orbit affects the heating of the earth... This can last from 10,000 to 100,000 years.” The reason it’s changing the heating is because earths orbit is usually in a circle, but it sometimes changes to an oval like orbit. When the orbit is “Oval like,” it’s closer to the sun. Therefore the earth is heated more, in some spots, when it’s in this orbit. These are some of the simplest reasons to prove my point, but there are plenty out there, look for
More sunlight reaches the equator of the planet causing a correlation between UV intensity and latitude.
The earth is like a living organism; it thrives full of life with a fragile balance. This balance has been thrown off by many different things. Water seems to be one of the biggest problems with this offset balance. Water is a magic liquid keeping all of life thriving. Humans drink and use water, plants use water, water is used in everyday life, and it’s slowly being taken away. In the future, there will be no water left to sustain life on earth.

7) Explain why temperatures on average become cooler and seasonality becomes greater as one moves from the equator toward the poles (use a diagram of the orbit of the earth
Relentless was the only way to describe the storms that raged over the Northern Hemisphere- snowstorms, hailstorms, thunderstorms, any storm possible was most likely in action in any part of the Northern Hemisphere. All of Great Britain was reporting heavy, continuous snowfall, the east coast of America still has severe thunderstorms raging across the entire coastline, the west coast was no better- softball-sized hail rained upon the once-temperate area. Russia and Canada seemed to be the worst off; both countries were reporting sub-zero temperatures and thick snowfall. Pressure systems were at an all-time low throughout most of the upper globe.
Tsunamis happen by landslides, underwater earthquakes and volcanic eruptions. For it to snow while a tsunami is happening, the temperature would have to be below
It would still be warm at the tropical zones and cold at both of the poles. The seasons that we experience now are caused by the tilt. For instance, in the summer, the Northern Hemisphere is tilted towards the sun, while the Southern Hemisphere is tilted away from the direct sunlight (“Earth”, 2016). The direct sunlight provides the Northern Hemisphere the maximum amount of direct sunlight. For places in the Southern Hemisphere, such as Australia, it provides the least amount of direct sunlight, which is why they experience winter at this time. When we have winter, it is the exact
The equator and poles relate to the unequal heating of the Earth because of the amount of sunlight they obtain. The equator gets more direct rays of sunlight, making it warm. However, the poles barely get any direct rays of sunlight resulting in making those areas colder. There are areas that are warmer and colder, thus acquiring the Earth to have unequal heating.
There are many reasons for why we have seasons. As the Earth orbits around the Sun, it is tilted at a 23.5 angle. Due to the elliptic, the Earth is tilted receives varying amounts of sunlight from the sun during the year, causing the seasons. There are two points throughout the year where the tilt of the Earth’s axis reaches its maximum angle towards the Sun, it then begins to move back the other direction. This generally happens around June 21st and December 21st. These days are known as solstices.
REBEKAH-- The Earth is in an oval around the sun which is called an orbit. The time it takes for the Earth to completely move around the sun, is an Earth year. The Earth also has an axis. What is an axis? An axis is an imaginary line that runs diagonally through the middle of the Earth. The axis is also the thing that helps us know where the equator is.
Summary: Seasons are formed by rotation of the earth which is cause of day and night, and also the rotation of the earth around the sun that provides us our year. Therefore, the sun never changes, only the earth make a cause to bring changes in light, darkness, and in the temperature. The earth rotates on an axis that is tilted. When the earth’s axis rotate closer to the sun, we expect summer, and when it spins far away from the sun, we experience winter.
