What are two differences between Earth and Mars?
Mars (diameter 6790 kilometers) is only slightly more than half the size of Earth (diameter 12750 kilometers). Note the difference in color between the two planets. Almost 70% of Earth’s surface is covered by liquid water. In contrast, Mars now has no liquid water on its surface and is covered with bare rock and dust.
What are the 2 different types of planets?
Planets are generally divided into two groups: the terrestrial and the giant planets. The terrestrial planets are the four inner planets: Mercury, Venus, Earth, and Mars. They are generally small in size (about the size of the Earth) and are predominantly rocky in composition.
What are the differences between Earth and Mars?
Earth is almost twice the diameter of Mars. Nearly 70 percent of Earth is covered with liquid water; Mars has none. The sun warms Earth’s surface to more than 100 degrees Fahrenheit. On Mars the temperature rarely surpasses the freezing mark.
What are the similarities and differences between Earth and Mars?
Mars is only about one-half the diameter of Earth, but both planets have roughly the same amount of dry land surface area. This is because over two-thirds of the Earth’s surface is covered by oceans, whereas the present surface of Mars has no liquid water.
What do Earth and Mars have in common?
Surface. The surface of Earth has land forms including the sea and land with mountains, valleys, craters and volcanoes. Mars also has valleys, craters and volcanoes, but doesn’t have the same composition of water Earth does.
What does Mars have that Earth doesn t?
Mars is a terrestrial planet like Earth. Unlike Earth, Mars has a very thin atmosphere made up mostly of carbon dioxide. As a result, it is much colder on Mars (average of -70 degrees F) than on Earth. There is evidence that open water in liquid form once existed on the surface of Mars like Earth.
What foods can grow on Mars?
Tomatoes, peas and leeks are just a few of the vegetables they could potentially grow on the red planet, according to a new study at a Dutch university. Scientists at Wageningen University & Research tried to grow ten different crops in simulated Lunar and Martian soil, as well as “normal” Earth soil.
