Why earth’s Magnetic Shield Matters
Prompt #1: Did it surprise you to know how much our magnetic field protects us?
No, it did not surprise me as to how our magnetic field is protecting us from the sun. How do you think life on Earth would be affected if magnetic field weakened significantly?
Just like the planet Mars life would become non-existent due to the fact that without water. The plants and food source would dry up leaving the human race to die of starvation. Have you heard anything in scientific news recently about Earth 's magnetic field?
The only thing that Ii have heard about the magnetic field that surrounds the earth is in reference to the ozone level. I heard that through the pollution that we are causing in the air is damaging the ozone and this is something that cannot be replace. When it is gone it is gone similar to yesterday.
What would happen if Earth 's magnetic field flipped? Learning from the planet Mars if the Earth’s magnetic field was to flip we would end up just like the planet desolated. I think that it is possible that we would survive for some time but eventually the radiation would get the best of the earth as well as the
2. If we were to run out of water my life would be different because I couldn't hydrate properly, get nutrients from the water, and I would not really have anything to drink because I really only drink water and two other liquids, but I drink water 90% of the time. I couldn't clean myself, so therefore I would stink all day.
It would effect Earth very negatively. This is because most plants would stop making energy from the sunlight and the animals that feed on autotrophs would not get that much food anymore, which would cause a ripple effect. Little energy would be made after that. Also, the planet would cool considerably.
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
The astronauts that go might get dehydrated from not having a natural source of water. They could extract water from the ground,
Ever since the origin of Earth was found, this question has wandered in the air. What will happen when Earth becomes uninhabitable? Scientists have turned to the next closest planet to Earth, Mars. There have been signs in the past of life on Mars. Many think that space exploration could be a reality. On the other hand, many think that the thought itself is unreasonable. Despite the sheet of ice found on Mars (Source D) and the possibility of extremophiles surviving in harsh conditions, the possibility of life on Mars is, indeed, a fantasy. The environment on Mars is too harsh to live in, there have been no signs of life on
Increasing the resistivity the resistor gets bigger, which directly effects the current by making it smaller. Indirectly the voltage to push the current through has to be stronger to push the current through. The value of R gets larger, you can change the resistance, but you would have to change out the resistor element to do this.
What would happen if we did not have water to use, drink or for fish to survive? California has a desolation problem for a long time, we do not have a lot of water to use and for fish to survive. To fix this problem before everything would be worse than now, California residents should spend money for the San Joaquin River Restoration Project.
evidence to show that water is in existence today. Looked tidally by Mars are two moons;
Everyday we take our resources for granted because they're at our fingertips. However, one of the resources we need the most is the resource that's most abused: water. We use water everyday for drinking, cooking, or watering plants. However, what would happen if water wasn't instant? Instead limited and scarce?
Despite the amounts of incoming radiation, very little actually reaches the Earth’s surface. One layer of protection the Earth provides is in the form of a magnetic field that deflects charged particles from reaching the Earth’s surface. This magnetic field is generated by a combination of the liquids within the Earth’s core and the interplanetary magnetic field generated by the Sun. This field reaches out thousands of miles from Earth, so when solar wind travels through space and encounters Earth’s
Its thin atmosphere and most likely a completely waterless surface shows that any life that was to land on the Red Planet would have a hard time trying to survive. At that time, when life was found on Earth, Mars had an ocean, volcanoes and deltas, the difference between Mars and Earth is Mars rapidly lost its hold on habitability. According to scientist Mars lacks the ability to have a protective magnetic field, most of the water left the surface and escaped into space, this was caused by the exposure of the surface to the cosmic rays and ultraviolet light. There were only a few packs of water left on the surface, some remained at the poles whereas others may have remained under the

During several years between approximately 1645 until 1715 – many areas within the northern climates experienced increased cold weather with streams and lakes frozen over for extended periods of time. This period of years has been labeled “The Maunder Minimum” (Hathaway) based upon the research of the astronomer Edward Walter Maunder ("Edward Walter Maunder"). Within his research, he noted the sun undergoes a cycle of sunspot activity and inactivity – this activity is also known as the magnetic activity. With the data that many researchers have gathers based upon Maunder – the earth is beginning to enter into another cycle of sunspot inactivity. Although we are beginning to enter the next cycle of sunspots, one major environmental concern we have now that was not a factor in the past is the CO2 emissions – known as greenhouse gases.
Actually, only one percent of the world's water has the capability of being used by us. About ninety-seven percent is salty seawater, and two percent is frozen in glaciers and polar ice caps. That only leaves one percent of the precious water that is to be used by not only people, but used by animals, plants, and food. Dehydration, which is the lack of water, will kill us faster than starvation, which is the lack of food. Since the plants and
Many centuries ago people did not need much energy. Back then, people used the sun or burned wood and straw for heat. People used the wind force in sails or horses to go anywhere in the world and used animals to do the work humans could not do. Although, humans did use simple machines that could ground grain, pump water, and even utilize steam power. Steam engines transformed over time and by the 18th century the modern steam engine, fueled by coal, could do the job of a team of horses. Since steam engines were much more favorable compared to air and wind power, steam engines were used to power factories and coal was used to heat up buildings.
