thanks yous verys muchs thank me l8r u %100 right
and here are the typing questions copy then paste into the test:
20. The gravitational attraction to the moon causes the Earth's oceans to bulge out in the direction of the moon. Another bulge occurs on the opposite side, since the Earth itself is pulled towards the moon (and away from the water on the far side). Since the Earth rotates, this happens twice a day. These are tides.
21. 1. lunar eclipse can only occur at Full Moon, and only if the Moon passes through some portion of Earth's shadow. This can occur only when the sun, Earth, and moon are aligned
2.A solar eclipse can only take place at the phase of new moon, A solar eclipse occurs when the moon gets between Earth and the sun, and the moon casts a shadow over Earth.
3. Solar eclipses outnumber lunar eclipses, BUT when you include "penumbral lunar eclipses", the number of solar and lunar eclipses is almost the same, with lunar eclipses slightly outnumbering solar eclipses.
