Choose the BEST answer to the following:
When the shadow of the Moon falls on Earth, we have a
(a) lunar eclipse.
(b) solar eclipse
(c) solar eclipse if it’s daytime and lunar eclipse if it’s nighttime.
(d) very dangerous event.
Lunar eclipses are always eclipses of a full Moon. That is, the Moon is always seen full just before and after Earth’s shadow passes over it. Why is this? Why can we never have a lunar eclipse when the Moon is in its crescent or half-moon phase?
Why don’t we have a solar eclipse and a Lunar eclipse every month?

- In countries at far northern latitudes, the winter months tend to be so cloudy that astronomical observations are nearly impossible. Why can’t good observations of the stars be made at those places during the summer months?arrow_forwardThis photo shows the annular eclipse of May 30, 1984. How is it different from the annular eclipse shown in Figure 3-10c? Figure 310 (a) Because the angular diameter of the Moon and the Sun vary slightly, the disk of the Moon is sometimes too small to cover the disk of the Sun. (b) That means the umbra of the Moon does not reach Earth, and the eclipse is annular, meaning a ring ("annulus") of the Sun's disk can be seen around the Moon. (c) In this photograph of an annular eclipse in 1994, the dark disk of the Moon is almost exactly centered on the bright disk of the Sun.arrow_forwardWill an eclipse occur in February 2025?

This is most closely associated with: Select one alternative: The ways in which our view of the sky depends on latitude. The combination of the Earth's rotation on its axis and its movement around the sun. The elliptical nature of the moon's orbit. The perspective dependence associated with parallax.
