Answer:
The Sun's temperature, which reaches around 15 million degrees Celsius in its core, steadily decreases with distance from the core, falling to 6000°C at its 'surface'. ... Instead, it rises to about 10,000°C in the chromosphere, and exceeds a million degrees Celsius in the corona.
Answer:
B
Explanation:
The mantle is divided into several layers: the upper mantle, the transition zone, the lower mantle, and D” (D double-prime), the strange region where the mantle meets the outer core.
Answer:
The largest lake in Central Europe is Lake Balaton
Answer:
When we talk about the <u>visible electromagnetic spectrum</u>, we know it starts in <u>violet-blue</u> and ends in <u>red</u>.
In this context the astronomer <u>Edwin Powell Hubble </u>observed several celestial bodies, and when obtaining the spectra of distant galaxies he observed that the spectral lines were displaced towards the red one (red shift), whereas the nearby stars showed a spectrum displaced to the blue one.
From there, it was deduced that the farther a body in the universe is, the more redshifted it is in its spectrum. This effect is due to the dilation and contraction of time by speed according to the relativity.
Now, the Sun is a massive star and the Earth is at certaind distance from it, therefore <u>time passes slower in the Sun than on Earth</u>. This causes the spectrum of the Sun to present lines with a lower frequency or longer wavelength than normal, that is, more towards red.
Convergent
boundaries or destructive plate boundary due to subduction, is an actively deforming
area where two or more tectonic plates of the lithosphere move towards one
another and collide. As an effect of pressure, plate material and friction
melting in the mantle, volcanoes and earthquakes are common near convergent
boundaries. Subduction or continental collision is created when two plates move
towards one another, depending on the nature of the involved plates. During
these collisions (between two continental plates) Himalayas and large mountain
ranges are formed.
