Prominences 1. Prominences are immense clouds of glowing gases that erupt from the upper chromosphere. 2. The loops or arches of gases may shoot as high as 100 000 kilometres from the surface of the Sun. This allows some of the surface gases, mainly hydrogen and helium, to escape into space.
Astronomy 10 Chapter 11 1. Both used to be normal stars but the white dwarf ran out of hydrogen, they are both subjected to gravitational theories. A Neutron star is a fluid of neutrons, as hot at its surface as the inside of the sun and has a greater magnetic field. 3. Because its density is so high, neutrons spin in the same way that electrons do so must obey the Pauli Exclusion Principle.
limb_flare_sm.jpg (5710 bytes)Solar flares are tremendous explosions on the surface of the Sun. In a matter of just a few minutes they heat material to many millions of degrees and release as much energy as a billion megatons of TNT. They occur near sunspots, usually along the dividing line (neutral line) between areas of oppositely directed magnetic fields. The biological effect. There is a growing body of evidence that changes in the geomagnetic field affect biological systems.
I will be discussing factors that cause differences in hazards posed by volcanoes. I believe the most important factor is the location of a volcano and the type of volcano. The most explosive and therefore dangerous volcanoes are found on destructive plate boundaries (Over 80% of the worlds volcanoes occur at these boundaries) for example the eruption of the Nevado del Ruiz in Colombia on the 13th November in 1985 which killed over 25000 residents of Arenas and Armero. At destructive plate margins, the oceanic crust is denser than continental crust and is therefore subducts under the continental crust. Due to high temperatures in the mantle of around 3000 degrees centigrade, this oceanic crusts melts and then rises due to the convection currents in the aesthenosphere .

However if it doesn’t have enough gas to create helium fusion it creates a red dwarf/red giant. Which involves lister Rimmer and oh wait wrong red dwarf This red dwarfs and red dwarfs burn out over thousands of years. They are the leftover of what could be classed as
Which of the following planets is NOT a gas giant? a. Earth b. Jupiter c. Saturn d. Uranus 16. The sun gets its energy from a. burning fuel b. nuclear fusion c. shrinking due to gravity d. convection 17. The number of on any planet can be used to estimate how old the surface is.
Pluto is a dwarf planet; it is the farthest planet from the sun. A dwarf planet is a planet that orbits around the sun. It has an orbit of 248 years that sometimes takes it inside Neptune’s orbit. Pluto is so cold that its oxygen and nitrogen, which is easy for us to breathe, is frozen solid there. This planet is two-thirds of our moon and it is the largest rock in the Kuiper belt.
Look at the chart below to see which elements are typically formed in supernova and which ones are not. 7. What is a supernova? (1 point) A supernova is the explosion of a star of big volume and mass also known as the death of a star. a. Fluorine | f. Manganese | b. Potassium | g. Iron | c. Titanium | h. Nickel | d. Vanadium | I. Zinc | e. chromium |
For example, the first book which was on this subject was made by Bill Kaysing who he himself published was called ‘’We never went to the Moon: America’s Thirty Billion Dollar Swindle’’. It was released in 1974 which was just after two Apollo missions were succeeded. This is one of the mass public medias that made people believed that it was an hoax. Another example which reinforced this idea is a film called Capricorn One. This movie is about a mission similar to the Apollo’s where several astronauts are ready to take off to space, but there was a problem with the rocket so they had to fake it to make the public believe.
