Differences and Similarities between Earth and Mars Similarities between Earth and Mars Mars has ice on the north and south pole like Earth. Mars has a hot day and a cold night like Earth. Earth`s inner core is mainly made out of solid iron.This is similar to to Mars, where the iron is mainly in the core. On Mars you can find iron,gold,silverand copper. Mars and Earth are both land planets not like some other planets which they just gas. On Mars the sun rises every 24 hours. Similar to Earth. Like Earth, Mars` weather can change a lot during the day. Like Earth, Mars has marks of water erosion. Differences between Earth and Mars Earth has more nutrient rich soil than Mars. Mars has two Moons and Earth has only one Moon. The iron on Mars is so close to the surface, you could find iron if you dug once with a spade. Different with Earth. On Mars you can`t find diamonds and otherrelated minerals. Not like Earth. Mars is the second smallest planet. Earth is the fifth smallest planet. Without Mars having plates, the volcanoes just keep erupting in the same spot (they do not die). Mars has less atmospheric pressure then Earth, many believe that this is the reason why liquid water can not exist on the surface of Mars. Reading 1b:
1b. Read the text below and check your answer.

Mars is called the Red Planet because of its reddish surface. There have been many explorations to Mars by humans since the mid-20th century. Scientists hope that we can find another planet to accommodate human life.

1. 2. 3.

There are major reasons why the climate on Mars is unsuitable for human life. Temperatures on Mars can be as low as -87 degrees Celsius and rarely get above 0 degrees Celsius. But the bigger problem is the lack of oxygen 95% of the atmosphere is carbon dioxide (CO2), and this is poisonous to breathe. Moreover, there is no water on Mars even though scientists have found traces of it.

However, as early as the mid-19th century scientists discovered that Mars had some similarities to Earth. A day on Mars is 24 hours, 39 minutes and 35 seconds, almost the same as a day on Earth. Mars also experiences seasons just as Earth does. However, the seasons are twice as long because a year on Mars lasts about twice as long as an Earth year.
