An informal expression that is more often used in casual conversation than in formal speech or writing. Colloquialisms are not substandard or illiterate speech, says Maity Schrecengost. Rather, they are idioms, conversational phrases, and informal speech patterns often common to a particular region or nationality. Not found everywhere, colloquialisms are words and phrases that we learn at home rather than at school (Writing Whizardry, 2010). See Examples and Observations below.
So what causes us to be able to see the moon during the day? The moon has an orbit around the earth and we can see it at night because of the reflection of the sunâs rays and energy that bounce back to the earth. This is what gives the moon the brilliant white glow. Itâs important to also remember that the earth has a rotation and an orbit around the sun.
Viewed from Earth, the Moon appears to rock slowly backwards and forwards so that we see a slightly different face throughout the lunar month. There are two main reasons for this. First, the Moonâs orbit around Earth is elliptical not circular so its rotation is sometimes ahead, and sometimes behind, its orbital motion. And second, the Moonâs rotation axis is not at right angles to its orbit around the Earth so we can sometimes see âoverâ or âunderâ its poles. Over time this means we actually get to see about 59 per cent of the Moonâs surface.
