Answer 1

Ответ:

1.  Mars is often called the red planet because a large layer of rust has formed on its surface.

2. Earth and Mars are quite similar planets. Because they both have a hard surface. The Earth's day lasts 23 hours 56 minutes, which is very similar to the Martian day. On Mars, as on Earth, there is a change of seasons.

3. Percival Lowell believed he saw a network of artificial canals on Mars.

4. in color, similar to Jupiter and Venus

Объяснение:

Answer 2

1. Mars is red primarily due to the presence of iron oxide, or rust, on its surface. The planet's reddish appearance is a result of the oxidation, or rusting, of iron-bearing minerals in the Martian soil and rocks. This gives the Martian landscape its characteristic reddish hue.

2. Venus is often considered the most similar planet to Mars in our solar system. Despite some significant differences, there are several similarities between the two planets:

   • Size and composition: Venus and Mars are both terrestrial planets, meaning they have solid surfaces. They are also similar in size, with Venus being slightly larger than Earth and Mars being smaller.
   • Atmosphere: Both planets have atmospheres, but their compositions are quite different. Mars has a thin atmosphere composed mainly of carbon dioxide, while Venus has a thick, dense atmosphere primarily made up of carbon dioxide with traces of sulfuric acid, making it extremely inhospitable.
   • Surface features: Both planets have a variety of surface features, including mountains, valleys, and impact craters. Mars has the largest volcano in the solar system, Olympus Mons, while Venus has a highland terrain with numerous volcanoes and a lack of large craters due to volcanic resurfacing.

3. Percival Lowell, an American astronomer, claimed to have observed a network of canals on Mars in the late 19th and early 20th centuries. Lowell believed that these canals were evidence of an advanced Martian civilization attempting to transport water from the polar ice caps to the planet's equatorial regions. However, subsequent observations and space missions, such as NASA's Mariner and Viking missions, have debunked Lowell's claims. There is no scientific evidence to support the existence of such canals or an advanced Martian civilization.

4. The planet most similar to Mars in terms of its dust storms is Earth. While Mars does experience dust storms, they are more intense and cover larger areas than typical Earth dust storms. These Martian dust storms can sometimes engulf the entire planet and last for weeks or even months. Earth, on the other hand, has regional dust storms that are generally less severe and have a smaller geographic impact. However, it's important to note that the dynamics and causes of dust storms on Mars are quite different from those on Earth due to the thin Martian atmosphere and the nature of Martian dust particles.
