There are some conditions that planets must have to support human life on them. First, the most important condition is that there must be enough liquid water on the planet. Second, the planet must hold an atmosphere. And the planet must have enough oxygen in the air for people to survive.
Read the text and answer the questions.
Mars is the fourth planet from the Sun and is commonly referred to as the Red Planet. The rocks, soil and sky have a red or pink hue. The distinct red color was observed by stargazers throughout history. It was given its name by the Romans in honor of their god of war. Other civilizations have had similar names. The ancient Egyptians named the planet Her Descher meaning the red one.
Before space exploration, Mars was considered the best candidate for harboring extraterrestrial life. Astronomers thought they saw straight lines crisscrossing its surface. This led to the popular belief that irrigation canals on the planet had been constructed by intelligent beings. In 1938, when Orson Welles broadcasted a radio drama based on the science fiction classic War of the Worlds by H.G. Wells, enough people believed in the tale of invading Martians to cause a near panic.
Another reason for scientists to expect life on Mars had to do with the apparent seasonal color changes on the planet's surface. This phenomenon led to speculation that conditions might support a bloom of Martian vegetation during the warmer months and cause plant life to become dormant during colder periods.

Hello everyone, today I will talk about Mars, the 4th planet in our solar system. The name of Mars originally comes from the name of the Roman god of war and agriculture. It may not seem like these two things go together, but they do. Mars protected those who fought for their communities and stayed home to raise crops for food. Mars has two natural satellites, and their names are Phobos and Deimos. With a radius of 2,106 miles (3,390 kilometers), Mars is about half the size of Earth. The atmosphere of Mars is much thinner than Earth's. It contains more than 95% carbon dioxide and much less than 1% oxygen. Mar's temperatures are from -151°C to 20°C. Mars is colder than Earth. If you were to stand on the surface of Mars on the equator at noon, it would feel like spring at your feet and winter at your head. Mar's surface is rocky, with canyons, volcanoes, dry lake beds and craters all over it. It's called Red Planet because iron minerals in the Martian soil oxidize, or rust, causing the soil and atmosphere to look red. One day on Mars takes a little over 24 hours. Mars makes a complete orbit around the Sun in 687 days. Thanks for listening.
