Why do sunspots appeared black when observed from earth?
The relative temperature of sunspots is lower than the surrounding temperature of the sun's surface. Since we adjust our camera's to the high temperature of the sun the relatively cooler sunspots appear black to us.
How does the sunspot cycle seem to influence life on earth?
Hh
How small would the Earth appear if it were inside a black hole?
If the Earth were inside a black hole, it would appear much smaller due to the extreme gravitational forces bending light.
Why do some French people appear to be black?
Because they are black. There are black people in virtually every country on earth.
What is retrograde motion as applied to a planet?
The "apparent" reverse or backwards motion of a planet as observed from Earth. The innermost planets appear to have a retrograde motion when viewed from Earth.
How is a lunar and solar eclipse alike?
Both lunar and solar eclipses are the result of positioning 3 astronomical bodies (earth, sun and moon) in a straight line relative to the observer. A solar eclipse is observed when the sun, moon, and earth are positioned in a straight line with an observer on the earth. A lunar eclipse is observed when the sun, earth, and moon are in a straight line with an observer on the earth. A lunar eclipse, as observed by an observer on the earth would appear as a solar eclipse as observed by an observer on the moon.
How is the sunspot cycle directly relevant to us here on Earth?
The 11-year sunspot cycle is not especially relevant to life on Earth, but longer cycles that appear to be connected to sunspots may also have an influence on Earth's climate. For example, in the 300 years that we have been tracking sunspot numbers, we have observed two extended minima of sunspots, the Maunder Minimum of 70+ years and the Dalton Minimum of about 40 years. We do not know precisely what the relationship is between sunspot minima and climate, but in each case the lack of sunspots seemed to be correlated with lower-than-normal temperatures. With our modern electronic technological civilization for the past 80 years, however, another factor may come into play. Peaks of the sunspot cycle are also associated with "solar storms" and higher-than-average levels of geomagnetic activity. This can cause problems with unshielded electronic devices, and a severe solar storm might cause widespread disruption of our satellite-based communications networks. In an extreme case, a massive solar storm might cause the failure of many weather satellites, leading the an inability to predict and track tropical storms or provide communications to military command-and-control systems.
If Black-African people were the first to appear on Earth who was second and third and so on?
they weren't technically black first of all they were Egyptian which is in Africa but they weren't "black"
What is the significance of sunspot regions the sun?
Sunspot regions on the Sun are areas of concentrated magnetic activity that appear darker than their surroundings due to lower temperatures. Studying sunspots can provide insight into the Sun's magnetic field dynamics, solar activity, and space weather phenomena like solar flares and coronal mass ejections. Monitoring sunspots is important for understanding how solar variations impact Earth's climate and technologies.
What is the sudden explosion near a sunspot?
A sudden explosion near a sunspot is known as a solar flare. This is a burst of energy and radiation released by the Sun that can cause disruptions in the Earth's atmosphere and affect our technology.
What are bursts of solar energy that occur over or near a sunspot?
Solar flares are brief outbursts that appear as a bright region above a sunspot cluster. Solar flares emit enormous quantities of energy in the form of ultraviolet, radio, and X-ray radiation.
Why do we see different constellations every season?
The stars and planets are observed from the earth, and because the earth is rotating and tilting on its axis, and is also orbiting the sun, the stars and planets appear to be moving in relation to the observers view.
