A day on Mars is about 24 Earth hours and 39.6 Earth minutes. So the day lengths on Mars and Earth are just about the same. Strictly speaking, that's the length of the sola â¦ r day. That's about a couple of minutes longer than the rotation period (called a sidereal day).
Quick Answer. A meaningful sentence is one that adds value to a paragraph by bringing in information. The sentence delivers a logical fact in addition to good subject-verb agreement, spelling and grammar. Every sentence must be written for a purpose, specifically to provide supporting facts.
3. Use a pair of commas in the middle of a sentence to set off clauses, phrases, and words that are not essential to the meaning of the sentence. Use one comma before to indicate the beginning of the pause and one at the end to indicate the end of the pause. 4. Do not use commas to set off essential elements of the sentence, such as clauses beginning with that (relative clauses). That clauses after nouns are always essential. That clauses following a verb expressing mental action are always essential.
