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.
They changed because the molecules of hydrogen and helium were moving so fast that they eventually escaped the Earth. 14. Explain how the greenhouse effect works and how it relates to global warming. The greenhouse effect is when radiation at visible wavelengths passes freely through the atmosphere and is absorbed at the ground. The ground heats up and emits infrared radiation.
The surface of Mercury and the moon share similar physical characteristics but also differ in certain aspects as well, outlining variations in their respective geological histories. In general, both the moon and Mercury show great similarity in size and from their substantial amount of craters which can be attributed to their lack of a prominent atmosphere that would burn up any primordial impacts. However, a closer look shows many differences. For example, the moon has 14 maria (lava flow regions), a relatively large number when compared with Mercury as it has few maria. This gives us a hint as to how fast Mercury and the moon cooled in relation to each other, as the cooler planet would
3. The chromosphere glows red because hydrogen gives off a reddish colour at these high temperatures. The corona 1. The corona is the extremely hot outermost layer above the chromosphere. 2.
If Jupiter were a shell, all the other planets and their moons could fit inside with room to spare. Jupiter could hold 317 of our earth's. Jupiter's diameter is 88,000 miles, thirty times the width of the United States. It orbits the sun at 8.1 miles per second (mps), or 19,160 miles per hour (mph). It is 485 million miles from the sun making it a very cold planet in the range of minus 240 degrees F. However, due to the enormous pressure of its mass, the center is estimated to be 54,000 degrees F., or five times hotter than the surface of the sun.
Comet tails are made up of simple ionized molecules, including carbon monoxide and dioxide. By action of solar wind, molecules are blown away, forming a thin stream of hot gases continuously ejected from the solar corona. In case you do not know the meaning of a solar corona, it is the outermost atmosphere of the Sun. Amazingly, the thin streams of high gases move at a speed of approximately 400 kilometers (250 miles) per second (as cited in Yeomans 1991 p. 185). In addition, a comet frequently also displays smaller, curved tails composed of fine dust particles blown from the coma by the pressure of solar
An atmosphere is an important part of what makes the earth viable. It blocks some of the sun’s dangerous rays from reaching earth. It traps heat, making earth a comfortable temperature and the oxygen within our atmosphere is essential for life.it was created in the 17th century from Greek word “vapour” and “sphere” which is a layer of gases surrounding a planet or other material body of sufficient mass that is held in place by the gravity of the body. Earths atmosphere is mostly Nitrogen (78%) also contains oxygen (21%) used by most organisms for respiration and carbon dioxide used by plants ,algae and cyanobacteria for photosynthesis ,also protects living organisms form genetic damage by solar ultraviolet radiation. Its current composition is the product of billions of years of biochemical modification of the paleo atmosphere by living organisms.
D. Scholar Geography 1 November 11, 2012 Test Corrections #1 Question: Which atmospheric heating process involves the emission of energy from an object? Correct Answer: E) Radiation My Answer: D) Why it’s Wrong: Radiation is the right answer because it has much stronger. It’s stronger than transmission, scattering, reflection and absorption. A good example would be: if your wearing a black shirt out in the sun you would be much hotter than if you’re wearing a white shirt. The black shirt would also fade over time because the suns rays would eat up the shirt.
The cycles alter the quantity of seasonal solar radiation reaching each latitude and astronomical accuracy can be used to estimate these cycles. Therefore, the location of incoming radiation referring to where the continents are situated is crucial. There has been a gradual growth in the energy output of the Sun in the industrial era, resulting in a small positive radiative forcing (Figure 2.2). Solar output has a direct impact on the heat in the Earth and on the abundance of some GHGs (e.g. stratospheric ozone).
With too many greenhouse gasses in the air, the earth’s atmosphere traps too much heat and light and eventually the earth get too hot and the temperature rises. This process of collective heat from the sun is called the greenhouse effect. Sometimes the temperature can change in a way that helps us. The greenhouse effect makes the earth appropriate for people to live on it. Without it, the earth would be freezing, or the earth would be extremely hot.
