Earth to Mars.One day, scientists hope to send astronauts to Mars Mars, in Roman religion and mythology Mars, in Roman religion and mythology, god of war. In early Roman times he was a god of agriculture, but in later religion (when he was identified with the Greek Ares) he was primarily associated with war. . How different is Mars from Earth? Read the facts about each planet. Then plot the information in the Venn diagram A graphic technique for visualizing set theory concepts using overlapping circles and shading to indicate intersection, union and complement. It was introduced in the late 1800s by English logician, John Venn, although it is believed that the method originated earlier. . Put the facts that describe Earth on the left portion of the diagram diagram /di·a·gram/ (di´ah-gram) a graphic representation, in simplest form, of an object or concept, made up of lines and lacking pictorial elements. and those that describe Mars on the right. Place the facts that describe both planets in the center of the diagram. EARTH It is a planet. It takes 365.26 days to orbit the sun. It has one moon. It has no rings. Its atmosphere is rich in oxygen and nitrogen. MARS It takes 687 days to orbit the sun. It has no rings. Its atmosphere is rich in carbon dioxide. It has two moons. It is a planet. Answer Key Earth: It takes 365.26 days to orbit the sun. It has one moon. Its atmosphere is rich in oxygen and nitrogen nitrogen (nī`trəjən), gaseous chemical element; symbol N; at. no. 7; at. wt. 14.0067; m.p. −209.86°C;; b.p. −195.8°C;; density 1.25 grams per liter at STP; valence principally −3, +3, or +5. . Mars: It takes 687 days to orbit the sun. Its atmosphere is rich in carbon dioxide carbon dioxide, chemical compound, CO2, a colorless, odorless, tasteless gas that is about one and one-half times as dense as air under ordinary conditions of temperature and pressure. . It has two moons. Both: It is a planet. It has no rings. |
