Pennsylvania is misspelled on the
Liberty Bell.
The sun is a main sequence star. It is about
93 million miles away. And is about 5 Billion yrs old and is 838,850 miles in
diameter. You can fit 1.3 million Earth’s inside it.
It’s rotation is faster at the equator 25 days than at the poles, 29 days. Therefore the rotation rate is averaged outTo be once every 27 days.
The suns main purpose is to transfer energy. It does this in the form of
light & heat.
The core makes up 2% of the sun’s volume. Its temp. is about 27mil.
oF. This is where the sun
transfers energy in the form of Hydrogen fusion.
Temp is about 4.5 mil. oF.
Its volume is 32%. Energy is transferred through
radiation.
Temp. is about 2 mil.oF. &
its volume is 66%. Energy is transferred through
convection.
convection is the transferred Energy through Liquid & gases.
The next layers are considered the sun’s
atmosphere. Remember that the sun is all gas, but these next layers are made
up of lighter gases.
Temp is about 10,000 oF. It is the innermost layer of the solar atmosphere. It’s energy is
transferred through visible light. Therefore it is often referred to as
the surface of the sun.
Temp is about 50,000 oF.
Transfers energy to the outer most layer. It does
this through a reddish light.
Temp is about 4mil. oF. Is a huge thin cloud of gas. It increases in
temperature because it acts like a greenhouse. It job is to prevents
atomic particles from escaping into space and causing solar winds.
All solar activity is caused by a disturbance in the suns
magnetic field.
Caused by the sun’s magnetic field slowing down the transfer of energy to the photosphere. Causing a cooler area, that appears darker. Sunspot activity increases every 11 years.
A prominence is a large, bright, gaseous feature extending outward
from the Sun's surface, often in a loop shape. Prominences are anchored to the Sun's surface in the photosphere, and
extend outwards into the Sun's corona.
A typical prominence extends over many thousands of miles;
the largest was seen in 1997 and was 216,000 miles long -
some 28 times the diameter of the Earth.
A solar flare is a sudden flash of brightness observed over the Sun's surface A solar
flare occurs when magnetic energy that has built up in the solar atmosphere and is
suddenly released. The flare ejects clouds of electrons, ions, and atoms through the corona of the sun into space. These clouds typically
reach Earth a day or two after the event.
There energy is equivalent to a billion megaton nuclear bombs, traveling at about
630,000 mph.
Occur on Earth due to charged particles from solar flares showering
the earth’s magnetic poles, this causes the Earth’s north and south
poles to experience an array of colorful lights.
