GENERAL KNOWLEDGE

Detailed explanation-1: -Model explains why the red planet is so red. Why is Mars so much rustier than the Earth? The red planet has more than twice as much iron oxide in its outer layers as our own, yet most planet scientists reckon the two bodies were formed from the same materials.

Detailed explanation-2: -Well, a lot of rocks on Mars are full of iron, and when they’re exposed to the great outdoors, they ‘oxidize’ and turn reddish-the same way an old bike left out in the yard gets all rusty. When rusty dust from those rocks gets kicked up in the atmosphere, it makes the martian sky look pink.

Detailed explanation-3: -Rusty Planet Mars is known as the Red Planet because iron minerals in the Martian soil oxidize, or rust, causing the soil and atmosphere to look red.

Detailed explanation-4: -In Mars’ gravity field, only 0.38 that of Earth, iron and everything else weighs less. Iron will not corrode readily because Mars’ thin atmosphere has virtually no free oxygen.
