The moons surface has mountainous highlands and large circular plains. The circular plains are called Maria. The mountain has heights up to 25000 feet.
The feature that covers much of the Moon's surface is called the maria, which are large, dark, basaltic plains formed by ancient volcanic eruptions. The maria are mainly located on the side of the Moon facing Earth.
he was amazed as from what he saw one night
The material that covers the surface of the moon is called regolith, which is also called moon dust. Regolith is made up of the crushed fine powder of volcanic glass and rock fragments.
During a solar eclipse, the moon's shadow only covers a small area on the Earth's surface due to the moon being much smaller than the Earth. In contrast, during a lunar eclipse, the Earth's shadow is much larger as it extends further into space and can darken the entire moon visible from Earth at that time.
Craters
many craters, mountains, and what Galileo referred to as 'seas'.
Water covers 71% of the Earth's surface
The lunar mare, which are large, dark areas, covers most of the lunar surface of the moon. Mare is the Latin word for sea, and these areas were once believed to be vast bodies of water. They are now known to be solidified lava plains formed by ancient volcanic activity.
Apart from the Moon itself? I would guess at the maria which covers 31% of the surface (Near side). or The Mantle.
Water covers 75% of the Earth's surface.
It covers about 71% of the Earth's surface.
The oceans surface is 100% water.
