What is the cause of solar prominences and the cause of sunspots?
Questions I'd like to include:
1)What is the cause of solar prominences, and the cause of sunspots?
2)Do u agree or disagree w/ the statement, "A total eclipse of the moon by Earth can happen only dring a full moon"?
3)First Nations and Metis astronomers use their own observations and cultural perspectives to explain celestial phenomena. Describe some examples of how First Nations and Metis perspective differ from those of scientists.
4)Why is it important to continue to study auroras?

Solar prominences are huge, loop like extensions emanating from the sun's photosphere outward through the corona. Prominences are loops of plasma, similar to the composition of the chromosphere. The largest prominence ever measured was roughly the radius of the sun itself. Solar prominences resemble eruptions similar to the eruptions of volcanoes here on Earth, which are caused by pressure within the Earth's mantle and crust. Although the chemical composition is different, perhaps the principle is the same, that the prominence is a solar "eruption" of hot solar gases.
Sunspots are cooler areas of activity onthe sun. They are visible as darker areas on the surface of the sun, and go through regular cycles one may observe. Sunspots are areas of high magnetic activity that resist the convective cycles of heat transfer within the sun's layers, so they appear darker as a result of lowered temperatures.
