Why lowlands of moon are dark?

Answer 1

There is no dark part or side of the moon.

The moon is geosynchronous in its orbit and rotation.

The same face of the moon always faces earth.

All sides of the moon do receive sunlight every month,

When there is a 'new' Moon the opposite side

facing away from earth or called the dark side, is receiving full sun.

except maybe some extreme polar regions all parts of the moon receive sun.

Answer 2

The lowlands of the Moon are generally dark because they are covered in basaltic rock, which is darker in color compared to the highlands. Basaltic rock is formed by solidified lava flows, giving these areas their dark appearance. Additionally, the lowlands tend to have fewer craters, which can result in less light being reflected back towards Earth.

Answer 3

Because the absence of light appears black.

Perhaps you were dimly striving for Olbers' paradox:

"If the universe is infinite and filled with stars, then every possible direction I look in, I should eventually see a star; some of them will be much further away, but there will also be more of them in any given imaginary circle. Every point in the sky should therefore be as bright as looking directly at the Sun. Clearly this is not the case. Why not?"

There are two reasons:

The first is that the observable universe is not infinite. We can only see stars the light from which has had time to reach us since the beginning of the Universe. That, currently, amounts to a distance of about 46 billion light years. (Yes, I know the universe isn't 46 billion years old. It's complicated.)

This, however, doesn't explain why we don't see residual light from the very early universe when every point in the universe was hotter than the center of a star.

The second reason, which does explain that, is that the universe is expanding and light from that long ago now appears to come from a point which is so distant from us that it's been redshifted down to the microwave region. To a microwave telescope, the night sky is not black at all.

Answer 4

Why do rain-bearing clouds look black?

The colour of any object depends on its ability to reflect selected wavelengths of light. Consequently, if the object does not reflect any colour, it appears black.

The tiny droplets of water in rain clouds scatter the white light of the sun.

Red is scattered first, and violet the last. This happens at such a high altitude that no rays of the sun reach the bottom of the cloud. Thus, we do not see the rays of the sun, and this results in a dark effect. As normal clouds have no water, the light is not scattered and thus look white.

Answer 5

This is a very good question. Light does come from the sun, but light is not generated from every single point in the sky. The reason you can look up and see the sky during the daytime is not because the sun is lighting up space itself. The light from the sun hits our atmosphere, and the atmosphere reflects and refracts light. Particles of dust are lit and reflect/refract light. It's a little bit like this: I can fire a green paint ball at the side of a big red barn. The paint ball remains intact until it hits the barn. Then, stand back. At night, the light from stars isn't strong enough to have the same effect on our atmosphere, but you do sometimes see a halo around the moon, which is similar to the sun's affect on the atmosphere.

Actually its a rubbish question. lol. so obvious.... we can oly see cause of light reflecting off of stuff like dust in the air. If notinhg is in the air then light cant reflect off anything sooooo in space theres no air and nothing to reflect off. for example if you shone a torch in space then you wouldn't see anything unless you looked directly into the bulb. Ok???

Answer 6

lowlands of moon are called maria which is dark in color. the answer to this question is quite simple. on the maria, there are mountains. when the sunlight fall on moon, the shadows of these mountains fall on maria or lowlands & from earth it appears as dark. it's also on earth.

Answer 7

The 'black' part of the moon is the part of the moon over which the shadow of the earth falls.

We have 'night' on Earth because our planet spins. As it spins, every 24 hours, we spend half of our time on the side which the sunlight can reach, and the other half on the side where sunlight cannot reach, giving rise to light and dark periods of day and night respectively.

In the same way that we orbit the sun, the moon orbits us. When the earth lies between the sun and the moon, we are able to see the shadow of the earth on the moon at night. When there is no shadow on the moon, the earth does not block any of the light from the sun, and correspondingly when there is a dark patch on the moon, the earth is blocking the sun's light.

Answer 8

The Moon has no atmosphere to "scatter" incoming sunlight.

The Earth has a blue daytime sky (ignoring clouds) because its atmosphere scatters blue light more than other colors.

Scientists call this effect "Rayleigh scattering".

Answer 9

1) I assume you're asking why it isn't as bright as day, given the (possibly) infinite number of stars in the universe. This is known as "Olbers' paradox"

2) The main reasons are:

A) The universe isn't infinitely old, therefore the light from distant stars hasn't yet had time to reach us and brighten up the night sky.

B) The universe is expanding, so the most distant light that reaches us has shifted a long way out of the visible spectrum ("Red Shift", due to the "Doppler Effect") and is measurable as the "Cosmic Microwave Background".

3) It isn't really black, it's mostly sort of dark grey, to people whose eyes are fully dark-adjusted.

Answer 10

The moon looks exactly the same from space as it does from earth, except that

the small features ... bright spots and dark spots ... on the surface will look different

when seen from different angles.
