GENERAL KNOWLEDGE

Detailed explanation-1: -The Moon’s surface is dominated by igneous rocks. The lunar highlands are formed of anorthosite, an igneous rock predominantly of calcium-rich plagioclase feldspar.

Detailed explanation-2: -The average composition of the lunar surface by weight is roughly 43% oxygen, 20% silicon, 19% magnesium, 10% iron, 3% calcium, 3% aluminum, 0.42% chromium, 0.18% titanium and 0.12% manganese. Orbiting spacecraft have found traces of water on the lunar surface that may have originated from deep underground.

Detailed explanation-3: -Like many planets in our solar system such as Mercury, Venus, and Mars, the moon is a rocky body with a combination of metallic substances found within the layers of its surface. While the moon is mostly made of iron, other metals found on the moon are magnesium, aluminum, silicon, titanium, gold, silver, and mercury.

Detailed explanation-4: -To the eye alone, the Moon is the biggest, brightest object in the night sky. Compared to Jupiter, though, it’s an astronomical pipsqueak. It’s a ball of rock about 2200 miles in diameter-a bit more than a quarter the size of Earth. It has no atmosphere to speak of, so there’s no weather.
