By the best figures, only 2-3 percent of the ocean floor has been properly mapped, at least in regards to the public domain. Certain militaries may be able to claim as high as 10 percent, but those figures are guarded nearly as closely as the other information contained in their files.
What else can I help you with?
Why don't moons have moons?
The moon has plenty of gravity. In accordance with its mass and radius, any object weighs about 16.5% as much on the moon's surface as it does on the Earth's surface.
Does the moon have copper in it?
Yes, small amounts of copper have been detected on the surface of the moon through samples brought back by Apollo missions and remote sensing instruments. However, the overall abundance of copper on the moon is much lower compared to Earth.
How much time the moon ray takes to come in the Earth?
The average time that it takes for light to travel from the moon's surface to the earth's surface or vice versa is about 1.255 seconds.
What is the size comparison of the Moon and Mars?
Mars is bigger than the Moon, having about twice as much surface area as the Moon. Mars-6,788 km Moon-3,476 km
How much more is the gravitational force of the earth than the moon?
The acceleration of gravity on the moon is about 1/6th the acceleration of gravity on earth. Any mass on the earth's surface feels about 6 times the downward force that it would feel on the surface of the moon.
Why is the moon's surface much heavily cratered than earth surface?
The moon has no atmosphere and is geologically inactive.The craters on earth have been eroded by weather, geological events and life
What was among the last frontiers to be mapped?
The deep ocean floor is among the last frontiers to be fully mapped. Only about 20% of the seafloor has been accurately mapped, leaving much of it still unexplored and unknown.
How much of Mercury has been mapped?
Mariner 10 mapped 45% of Mercury back in 1974/75, and Messenger just added another 30% back in January 2008.
Why moon don't have gravety?
The moon has plenty of gravity. In accordance with its mass and radius, any object weighs about 16.5% as much on the moon's surface as it does on the Earth's surface.
What is the features that cover much of the moon's surface?
gravity
About how much is the Moon's gravitational force compares to the earths?
The weight of any object on the surface of the moon is 16.55% of its weight on the surface of the Earth.
How much of the entire moon's surface is illuminated by the sun at first quarter?
At any time, half of the entire Moon's surface is illuminated.
Where is Moon's crust located?
It is located on the surface of the moon, much like the skin of an apple.
How does Moon's gravity compare with earth's?
An object on the moon's surface weighs 16.55% as much as the same object weighs when it's on the Earth's surface. That's about 1/6 as much.
How much of the moons surface can be seen from the earths surface when full?
The Moon is roughly spherical; weather permitting, we see the near half of the Moon.
How much higher must the cratering rate have been in the past to cover the entire lunar surface with such craters in the 4.6 billion years since the moon formed?
what is the primary source of erosion on the moon
How much surface of the moon is always facing the sun?
50%.
