A star's spectrum refers to the "amount of light" that stars they give off according to varying wavelengths. Since we cannot tell the amount of light a star gives off quantitatively from Earth, we can differentiate them according to how bright they appear.

b. Which spectrum is most common in stars?

Stars are classified according to their spectra (elements in the star). They are classified into 7 types (O, B, A, F, G, K and O). The most common type is M, however, it gives off a dim light.

c. How can it differ from start to star?

Although stars follow a continuous spectrum, the spectra of a star differs from each other because they do not give off the same amount of energy at the different wavelengths.

d. What does the spectrum tell us about the star?

The spectrum can tell the surface temperature of the star. This means that a blue star (we often see it as a white-colored star from Earth) is hotter than that of a yellow star. A red star is considered the coolest star among all.

The spectrum of stars also allows the astronomers to study composition of the stars according to their wavelengths.

Jena is reading about factors that affect Florida's climate. One sentence reads: Most of Florida is less than 100 feet above sea

Marrrta [24]

Answer:

Jena is reading about the elevation.

Explanation:

Elevation is the altitude (height) above the sea level. The Florida being at the height of less than 100 feet is its elevation.

The major factor that affects the climate of that region is its elevation.as the elevation increases i.e. the height of the place from sea level increases the temperature of that place lowers.

For every 1 kilometer rise in elevation the temperature decreases by 6.5 degree Celsius. Hence, Jena is concerned about the elevation.
