why do sunspots appear darker than their surroundings

Why do sunspots appear darker than their surroundings? The Sun is by no means a completely uniform color. Sunspots, which can be seen as dark areas on the surface of the Sun, are a common occurrence. Most sunspots are large, measuring around 8,000 miles across; in fact, they have the same diameter as Earth! Sunspots appear darker than their surroundings because they are at a lower temperature. The surface of the Sun is usually around 5,800 degrees Kelvin (9,980 degrees Fahrenheit), while the center of a sunspot is closer to 4,300 degrees Kelvin (7,280 degrees Fahrenheit).

 why would a newborn need a blood transfusion

why would a newborn need a blood transfusion

We rounded the corner after scrubbing in for the obligatory 3 minutes. As we neared the fourth pod, I saw that the neonatologist was sitting on a stool right beside Tucker s isolette. We were only 4 days new to the NICU experience, but I knew enough to know that if the neonatologist was camped out at our isolette, it wasn t a good sign. We walked up and I peered in at the teeny 1 pounder. The impossibly small human behind the plexiglass was jerking his twig thin leg, in an unnatural movement, his underdeveloped nervous system still trying to reconcile that he was outside the womb. My mind was trying to reconcile the same thing. An alarm screamed. The neonatologist began rubbing Tucker s back, reminding him to breathe. What s wrong? I asked, still unsure of which alarms meant what. Well,

 why do you get your tonsils out

why do you get your tonsils out

What Is a Tonsillectomy? Have you ever had? That's when your tonsils, in the back of your throat, get sore and infected. If tonsillitis happens to you a lot, the doctor may suggest you have an operation to remove your tonsils. Or maybe you have really large tonsils that make it hard for you to breathe at night. That's another reason the doctor may say they should come out. Your tonsils are two lumps of tissue that work as germ fighters for your body. The trouble is that sometimes germs like to hang out there, where they cause infections. In other words, instead of fighting infections, the tonsils become infected.

why is oil sometimes referred to as liquid sunshine

All the energy contained within oil (the energy we use to power cars,. ) originally came from the sun. Oil is a fossil fuel, derived from long dead living things (mostly plants). These plants, through the process of photosynthesis, got their energy from the sun. These plants, over millions of years, converted into what we now know as crude oil. The oil is a metaphorical battery filled with solar energy (sun shine) in that its energy came from the sun. This does not in any way mean that the burning of fossil fuels equates to how we commonly use the term solar energy or solar powered, but on the grand scheme of things, all life on Earth is powered by the sun. I have to admit Iвm a bit of an eavesdropper. I try not to make a habit of it, but sometimes overhearing a conversation is
