Transcript of Earth has been Struck by a Small Asteroid

The years will be the same because the asteroid that hit the Earth did not affecy the orbit, only its rotation. By: Tylar Watson, Ashley Evans, Breanna Murrin,
Aspen Evans Earth has been Struck
by a Small Asteroid How will the Length of a Year
Change? How will the length of a day change? How will the length of ‘length of day’ and ‘length of a night’ change? What will our new climate be like? How will the seasons change? What will the tides be like? The day will also be longer because the Earth's rotation will take longer and the indirect sunlight will hit the Earth, due to the nonexistence of the Earth's axis. At the North and South Poles, the sun will always appear at the horizon because the sun will be facing the Earth all day around the poles. The days and nights will be longer, hotter in the day, freezing cold in the night. The lengths of day and night will be even. There will be no seasons at all because the climates in the different areas would always be the same. People usually determine seasons by the differences in temperatures, but there will be little changes in the temperature, resulting in one season: either winter in the North and South or summer in the Equator. The climate will vary in the different areas. In areas closer to the Equator, it will be much hotter than usual. In areas further from the Equator (as in regions closer to the North and South Poles), it will be much colder. It will be most likely that the nights will be much cooler than the days. This will be because the Sun will always have direct rays on the Equator and indirect rays on the regions further up or down.
Because the moon may or may not have a full and new moon each month, the tides will might not be spring tides, and then same for neap tides. We will also have at least two high tides and low tides a day, and one extra high or low tide. Since the days will be longer, there will still be 2 high tides and 2 low tides every 6 hours every day but there would be another or a part of either a low or high tide depending on the day which means that the tides would never be consistent. How will these changes effect: food sources, energy use, travel, timing, our calendar, international trade? Identify two major problems that will likely be experienced and possible solutions. Two major problems would be food sources and international trade. These are major problems because without the correct sun tilt and direct/indirect sunlight, we won’t be able to grow crops the way we’re used to because it will either be too cold or too hot. International trade will be an issue because all of our timing will be off so no one would be awake at ports and airplanes to control the ships and planes. Plus, no one would know when to send things internationally because our time zones might also be off. How will the forecast of the Earth change? If the Earth didn’t have a tilted axis, there wouldn’t be any seasons. Regions in the north and south would always be cold, while the equator would always be hot. If the habitable world were a humid tropical zone like the rain forests of the Congo, unrelenting rainfall would quickly erode soil in any areas cleared for farming, and would leach nutrients down below root level, swiftly rendering tilled land infertile for crops.
Humans would also be plagued by disease pathogens, which thrive in warm, humid environments. Winter protects much of the world's population from tropical insects (which carry deadly diseases) and a long, nasty list of tropical diseases of humans, crops and livestock.
This could affect the annual cycle of animals’ migration, mating, and hibernation. What are some Possible Problems The poles would have the sun at
the horizon all the time. Everywhere
else would have 12 hours of daylight
and 12 hours of night. Length of Daylight THE END!
