BLACK HOLE'S!!!!!!!!

Hey guy's today we will be talking about Black Hole's. And yes Black Holes are BLACK HOLES!!!!!!!!!. Ok now you know what black hole's are bye just kidding. Ok a black hole is a region of space where the gravity is so strong that nothing can escape it not even light can escape it. Albert Einstein discovered black holes through the theory of relativity. The theory was published in 1916.The gravitational force is strong near a black hole because all the black


holes matter is concentrated at a single point in its center.




Black holes are like such messy eaters. Some material won't


reach the event horizon but instead is caught up in powerful


magnetic fields exist around black holes

The Sun (Ahh It's Hot)j

The Sun is a huge, glowing ball at the center of our solar system. The sun provides light, heat, and other energy to Earth. The sun is made up entirely of gas. Most of it is a type of gas that is sensitive to magnetism. This sensitivity makes this type of gas so special that scientists sometimes give it a special name called  plasma. Nine planets and their moons, tens of thousands of asteroids, and trillions of comets revolve around the sun. The sun and all these objects are in the solar system. Earth travels around the sun at an average distance of about 92,960,000 miles from it. The sun's radius  is about 432,000 miles  that's 109 times Earth's radius.

The part of the sun that we see has a temperature of about 5500 degrees C (10,000 degrees F). Astronomers measure star temperatures in a metric unit called the Kelvin. One Kelvin equals  1 Celsius degree (1.8 Fahrenheit degree), but the Kelvin and Celsius scales begin at different points. The Kelvin scale starts at absolute zero, which is -273.15 degrees C (- 459.67 degrees F). Thus, the temperature of the solar surface is about 5800 K. Temperatures in the sun's core reach over 15 million Kelvin.

STARS

Hey guys I'm going to be talking about stars yea that thing in the sky that you look at every night . Sometimes you cant see many or any stars because of light pollution we see allot less stars. Years ago we used to see almost every star in the sky. Stars are born in nebulae with many clouds of dust and gas. Some of the gas  in a nebulae is hydrogen gas. Over millions of years of gravity causes the hydrogen gas to collect in a cloud and more and more gas is pulled into the cloud it begins to spin as the cloud spins atoms of hydrogen gas bump into one another. The faster the gas spins the more the atoms bump togethr.

OUR TRIP TO FLORIDA

Hey guy most of you know we went to Florida to see the space shuttle launch well for the people who don't know what happened here it is. Ok we went on this huge coach bus it had a TV and we watched a ton of movies but the bathroom was very stinky and the light's would turn on and off and sometimes it would lock you in the there so then we rode on the bus stopped at a couple of gas stations.Then once we got to the retreat center we went in the rooms for a while and we were going crazy because there was nothing good on the TV and we only had like five channels and allot of them where where religious then we went to Kennedy Space Center then we look around watched a IMAX movie almost everybody fell asleep then we went on the simulator and Shelby screamed at the top her lungs so it was kinda annoying.Then we went to the gift shop and I bought a rocket and Kenneth bought a $40 chess set.Then we went to the bus and drove to pizza hut and me,Gus,Shelby,Taylor,and Tyler sat at the same table and we got a half cheese half peperoni pizza and cheese bread sticks and a drink.Then we went back to the retreat center and in one of the bathrooms there was a bidet (the squirter thing in the toilet) and we turned the nob that turns it on and we didn't know what it did so when we turned the nod it squirted the door and some people then we went to sleep. Then the next morning we woke up got dressed and went to breakfast it was a good breakfast then we got on the bus and went to coco beach it was very fun alot of people got soaked.Then we went back to Kennedy space center and saw the stuff that we didn't see yesterday and we went back on the simulator but it was alot more fun because Shelby didn't scream (thank god).Then we went back to the retreat center and ate dinner then we went outside and played tag and ms.crimmenger was it and she was very very fast then we went back to the room and me,Kenneth,Zak,Gus,Daniel,Tyler,and Mr.sellers watched a movie on netflix and watched it on the projector then we went to sleep the we got on the bus at like 7 o,clock AM then we got back. If you watch the videos below you will see something we never got to saw. BYE PS.i want to go back to Florida

Tsunamis

Tsunamis form from earthquakes, volcanic eruptions, or landslides that occur under the sea. When this event happens under the water, huge amounts of energy are released as a result of quick upward bottom movement. For example, if a volcanic eruption occurs, the ocean floor will quickly move upward several hundred feet. When this happens, huge volumes of ocean water are pushed upward and a wave is formed. A large earthquake can lift thousands of square kilometres of sea floor, which will cause the formation of huge waves. The Pacific Ocean is especially prone to tsunamis.

finally the last volcanoe blog

Mt.Saint Helen's is one of the volcanoes in the ring of fire but there is others like Mt.Fuji ,Mt.Pinatubo ,and Paricutin. home of almost 1000 volcanoes.

volcanoes

volcano is an opening in a planet's surface or crust which allows hot magma, ash and gases to escape from  below the surface. Volcanoes are generally found where tectonic plates are diverging or converging. A mid-oceanic ridge, for example the Mid-Atlantic Ridge, has examples of volcanoes caused by divergent tectonic plates pulling apart; the Pacific Ring of Fire has examples of volcanoes caused by convergent tectonic plates coming together. By contrast, volcanoes are usually not created where two tectonic plates slide past one another. Volcanoes can also form where there is stretching and thinning of the Earth's crust such as in the East African Rift, the Wells Gray-Clearwater volcanic field and the Rio Grande Rift in North America.

Island arcs

Ok an island arc is a curved chain of volcanic islands.Island arcs are usually found in the Pacific where they ring the ocean on both sides; the Aleutian Islands off Alaska are an example.

more island arcs

An island arc is a curving series of volcanic islands that are created through the collision of tectonic plates in an ocean.The particular type plate boundary that yields island arcs is called a subduction zone. In a subduction zone, one lithospheric plate is forced downward under an upper plate. Continual tectonic movement pushes the lower plate deeper until it reaches a depth where temperatures are sufficient to begin to melt the subducted plate and form magmas. These magmas then rise through fractures and melt their way through the overlying crust to be extruded in the form of volcanoes. The volcanoes are generally andesitic in composition. If the overriding plate is oceanic, then volcanoes are extruded underwater and may eventually rise high enough to become islands. The volcanoes form in a line because the angle and rate of subduction, and hence the distance to the depth where melting occurs is consistent. Because the surface of Earth is curved, the line of volcanoes forms in an arcuate pattern in much the same manner as an arc is produced when a planar surface intersects a sphere.teehee.bye

How a Volcano works

About Volcanoes

A volcano is a opening in the earth's surface crust through which lava, ash, and gases are ejected.

Volcanoes occur usually on or near crustal plates or boundaries, although certain volcanoes known as hotspot volcanoes can occur virtually anywhere. Today’s existing terrestrial volcanoes are believed to have formed when molten rock or magma welled up in the Earth’s interior pushed its way to the surface causing the volcanoes’ initial eruptions.

Volcanoes all generally fit into one of six different categories: Shield volcanoes, Cinder volcanoes, Stratovolcanoes, Submarine volcanoes, Subglacial volcanoes, and the most powerful volcano of all, the Supervolcano. A Supervolcanic eruption can be catastrophic to entire regions both climatically and geologically. Individual volcanoes are typically described as being either active (currently erupting)run, dormant (not currently active)yeah or extinct (not expected to ever erupt again)yeah.

Some of the most famous volcanic eruptions around the world include the Yellowstone Caldera in Yellowstone National Park, Lake Toba in Sumatra, Indonesia, and the devastating eruption of Mt. St. Helens in southwest Washington State in 1980.teehee!
