How do solar flares affect the Earth?

Solar flares can make communication by radio and telephone difficult at times.

The earth itself is strongly protected by its magnetic field. When there is a great deal of solar activity we experience this as a beautiful display of Aurora Borealis reaching out from the North and Aurora Australis reaching out from the south. The more active the sun is, the further away from earth's magnetic poles this light will be visible in the sky.

Sometimes the ionic particles from the sun are of such a strength that they will saturate the electronics on board various satellites. This will interfere with satellite communication and we might lose TV signals or even phone connections. The ionic particles can in some cases destroy parts of a satellite's electronics and cause it to malfunction.

There is little to indicate that this radiation from the sun is of any danger to electronics located down on earth..

A massive solar super storm could possibly penetrate the earth's magnetic shielding to a certain extent and cause problems with ordinary electronics. This fortunately does not happen very often and would most likely render quite a few of our satellites useless.

One day if the worst come to the worst and we do have a solar super storm, then I will just be outside watching the sky and letting myself be fascinated by this amazing show from the twin auroras. They might even be visible in daylight.

In 1870, a severe solar storm (there were actually a series of these throughout the 1870s) caused such an intense inductive current in long telegraph wires that operators no longer needed to connect their systems to batteries in order to send telegrams. In a couple of cases, the induced current was high enough to start fires in the telegraph offices!

Particles in the sun can affect power lines on the earth in the same way and there have been 2 large power outages attributed to solar activity. These are somewhat predictable and the solution is usually to distribute the power better so that long power lines don't need to carry as much power. In other words have as many power plants on line as possible during these events.

The radiation from solar flares is deadly to people above the earth's magnetic shield and above the atmosphere for example astronauts travelling to the moon, on the moon, travelling to Mars or on Mars need heavy shielding to survive a strong solar storm.

When solar flares increase solar wind from the corona what do they cause in Earth's upper atmosphere?

It increases the number of particles reaching the Earth's upper atmosphere. Normally, Earth's atmosphere and magnetic field block these particles. However, near the North and South poles, the particles can enter Earth's atmosphere, where they create powerful electric currents that cause gas and molecules in the atmosphere to glow. The result is rippling sheets of light in the sky called auroras.1 word for it would be?the aurora borealis

Do you notice when solar flares happen?

If you are in the right place, you know that big solar flares have happened, because you see the results of the energized particles striking Earth and being channeled into the north pole and south pole. These results are called the Northern Lights, although they occur at the South pole too.

Can solar flares affect earth's weather?

It can sometimes affect the earths weather as the energetic particles affect the atmosphere and cause auroras and winds. If a potential solar flare was released then it would be potential as it can do biochemical damage to the human body. This info was obtained from wikipedia in the hazards section so don't get me wrong.

How are sunspots prominences solar flares and CMEs related?

They all occur from the Sun's magnetic fields. The intense magnetic fields associated with sunspots might cause prominences, which are huge, arching columns of gas. Gases near sunspots sometimes brighten suddenly, shooting outwards at high speeds. These violent eruptions are called solar flares.

How do solar activities such as a sunspots and solar flares affect earth?

Solar flares come from sunspots, and when they are heavy, it is common for television, radio and cell phone use to become problematic to a certain degree (more an annoyance than anything). This same activity also causes the Aurora Borealis, or "Northern Lights". It is suspected that sunspot activity over repeated long periods (lasting several hundred years each) may be connected to climate fluctuations here on earth, but this is still being investigated.

How is the earth protected from solar flares?

Two things I believe. The magnetosphere first of all. The magnetosphere surrounds Earth and near space with a field of charged magnetic particles. Since solar flares are magnetically charged, this helps deflect them. Also, the ozone filters much UV rays and dangerous particles from the Sun. The reason many are worried about the ozone is because if the hole or holes in the ozone (created by harmful chemicals) keep expanding, the temperature of Earth will get increasingly warmer.

What is a solar aerator?

Just like the human body, all bodies of water (ponds, lakes, etc.), need oxygen to improve and maintain water quality.

Some oxygen is provided by algae in the water. Algae are microorganisms that are naturally present in water and work to consume and sequester carbon dioxide and other water contaminants.

As part of this process the algae provide oxygen to the water while the sun shines. When the sun is no longer shining or when the contaminant levels in the water are quite large the algae stop providing enough oxygen. The oxygen content of the water drops quickly resulting in fish-kills and smelly stagnant water.

That's where solar aerators come in.

Well designed solar aerators mix air into the water anytime, whether the sun is shining or not with backup power for a minimum of 2-3 consecutive cloudy days.

Well designed solar aerators include 1-2 year electrical and pump warranties in conjunction with five year solar panel warranties.

Well designed solar aerators publish cost of ownership studies that show average annual maintenance costs.

Poorly designed solar aerators only operate in the daytime sun, leaving the fish to hold there breath at night when it is needed most.

Because Solar aerators use only the energy of the sun they have a negative carbon footprint.

How does a solar panel work?

Silicon atoms have room for eight electrons in their outer bands, but only carry four in their natural state. This means there is room for four more electrons. If one silicon atom contacts another silicon atom, each receives the other atom's four electrons. This creates a strong bond, but there is no positive or negative charge because the eight electrons satisfy the atoms' needs. Silicon atoms can combine for years to result in a large piece of pure silicon. This material is used to form the plates of solar panels.

Here's where science enters the picture. Two plates of pure silicon would not generate electricity in solar panels, because they have no positive or negative charge. Solar panels are created by combining silicon with other elements that do have positive or negative charges.

Phosphorus, for example, has five electrons to offer to other atoms. If silicon and phosphorus are combined chemically, the result is a stable eight electrons with an additional free electron along for the ride. It can't leave, because it is bonded to the other phosphorus atoms, but it isn't needed by the silicon. Therefore, this new silicon/phosphorus plate is considered to be negatively charged.

In order for electricity to flow, a positive charge must also be created. This is achieved in solar panels by combining silicon with an element such as boron, which only has three electrons to offer. A silicon/boron plate still has one spot left for another electron. This means the plate has a positive charge. The two plates are sandwiched together in solar panels, with conductive wires running between them.

With the two plates in place, it's now time to bring in the 'solar' aspect of solar panels. Natural sunlight sends out many different particles of energy, but the one we're most interested in is called a photon. A photon essentially acts like a moving hammer. When the negative plates of solar cells are pointed at a proper angle to the sun, photons bombard the silicon/phosphorus atoms.

Eventually, the 9th electron, which wants to be free anyway, is knocked off the outer ring. This electron doesn't remain free for long, since the positive silicon/boron plate draws it into the open spot on its own outer band. As the sun's photons break off more electrons, electricity is generated. The electricity generated by one solar cell is not very impressive, but when all of the conductive wires draw the free electrons away from the plates, there is enough electricity to power low amperage motors or other electronics. Whatever electrons are not used or lost to the air are returned to the negative plate and the entire process begins again.

One of the main problems with using solar panels is the small amount of electricity they generate compared to their size. A calculator might only require a single solar cell, but a solar-powered car would require several thousand. If the angle of the solar panels is changed even slightly, the efficiency can drop 50 percent.

Some power from solar panels can be stored in chemical batteries, but there usually isn't much excess power in the first place. The same sunlight that provides photons also provides more destructive ultraviolet and infrared waves, which eventually cause the panels to degrade physically.

A:When sunlight hits the solar panel it produces electricity for loads of homes. A:If you want to know how solar panels work....

A solar, or photovoltaic, cell is used to convert energy in the form of electromagnetic radiation that is incident on it (ie that transfers light energy to it) into electrical energy.

The cell itself consists of 2 different types of doped semi-conductor material.

Doping is the process whereby impurity ions are introduced to the crystal lattice, with either one or fewer, or one extra free electron. Once doped, the materials are notelectrically charged.

In the P-type material, there are excess holes, and in the N-type material, there are excess electrons. When layered on top of each other, at the junction, the electrons fill the holes.

This means that on the P-side, there is a shortage of holes (as opposed to the number it would normally contain) so the material has a negative charge. On the N-side, there is a shortage of electrons, giving it a positive charge. This establishes a potential difference of 0.5V, but there is no current, as there are no free charge carriers at the junction.

When light shines on the cell, electrons are released by photons from the electron-hole pairs (photoelectric effect*), on the P-side of the junction. This alters the equilibrium at the junction. The electrons then flow to the positively charged n-type side, and the holes flow to the p-type side. This creates a current.

If there is an external, unbroken circuit attached to the cell, charge carriers are pushed through. As they go, they dissipate energy.

- If there is a greater light intensity, more photons are released per second, so there are more charge-carriers liberated per second, a greater current, and more power available.

* Particular frequencies of photons, or quanta of light energy, are absorbed by electrons so they have enough energy to move to a higher energy level/leave the surface of the metal.
