What are facts about the first quarter moon?

Answer 1

the moon has lots of craters,rocks 1/6 of the gravity then the earth!

Answer 2

the Moon is very small around about the same size as Australia

it controls tidal waves

moves away from earth every inch in every year

Answer 3

The three major features of the moon's surface are:

• It's Maria, which is the Latin word for sea, was mistakenly thought to be a sea/ocean by Galileo. The Maria of the moon is actually hardened rock formed from lava flow occurrences that is believed to have occurred in between 3 and 4 billion years ago.

• The moon's craters is the second one. A crater is a rounded pit. The moon's craters are believed to have been formed by meteoroids crashing onto its surface and soon be pulled away from the moon by the sun's gravitational pull and been sent away by Earth's gravitational pull that has the ability to clear debris from it, but still leaving permanent marks on the moon.

• Highlands / Mountains is the final major feature of the Earth's surface. Most of the moon's surface is covered by highlands / mountains. The highlands are called lunar highlands, same with the moon's mountains being lunar mountains.

Answer 4

1) the waning crescent informs us that the moon appears to be getting smaller (thinner)

2) the waning crescent informs us that the moon is slowly moving into the glare of the sun.


3) the waning crescent informs us the moon will soon become a new moon and a day or so later will become a waxing crescent.

Answer 5

1. The Moon formed out of the Earth

Scientists now think that the Moon was formed when a Mars-sized object crashed into our planet about 4.5 billion years ago. The collision was so large that a huge spray of material was ejected into space. The orbiting ring of debris gathered itself into a sphere, and formed the Moon. How do we know that this is how the Moon probably formed? The Moon seems to be much less dense than the Earth and lacks a lot of iron in its core. Scientists think that the Moon is made up of the upper crust material, which has mostly lower density, than the composition of the Earth.

2. The Moon only shows one face to the Earth

Although the Moon used to rotate in the sky compared to our point of view, it has been slowing down billions of years. And at some point in the distant past it just stopped turning from our perspective. The Earth's gravity holds the Moon in orbit, but it pulls differently at various parts of the Moon. Over a long period, gravity slowed down the Moon's rotation so that it finally stopped, and always displayed one face to the Earth. A similar situation has happened with most of the large moons in the Solar System. In fact, in the case of Pluto and Charon, but objects are tidally locked to each other, so they present only one face to the other.

3. The Moon is slowly drifting away

Although the orbit of the Moon seems nice and stable, our only natural satellite is actually drifting away from us at a rate of 4 centimeters a year. This is happening because of the conservation of momentum in the orbit of the Earth. In about 50 billion years from now, the Moon will stop moving away from us. It will settle into a stable orbit, taking about 47 days to go around the Earth (it takes 27.3 days today). At that point, the Earth and the Moon will be tidally locked to each other. It will look like the Moon is always in the same spot in the sky. Of course, the Sun is expected to consume the Earth in about 5 billion years, so this event may not happen.

4. The Moon looks the same size as the Sun

This is an amazing coincidence. From our perspective here on Earth, but the Moon and the Sun look approximately the same size in the sky. Of course, the Sun is much much bigger than the Moon. The Sun happens to be 400 times larger than the Moon, but it's also 400 times further away. This wasn't always the case. Billions of years ago, the Moon was much closer than the Sun, and would have looked larger in the sky. And the Moon is moving away from us, so in the distant future, the Moon will look much smaller than the Sun.

5. The Moon causes most of the tides… but not all

You might know that the tides on Earth are caused by the gravitational pull of the Moon. But it's not the only thing pulling at the Earth's water, the Sun is helping out too. This is why we get very high and low tides from time to time. When the gravity of the Moon and the Sun line up, we get the biggest and smallest tides. Did you know that the Moon is also pulling at the crust of the Earth causing it to bulge up? You actually move a few meters every time the Moon is overhead, but you just don't notice.

Answer 6

1. They are caused by light reflected off the Moon's surface from the Sun as it orbits Earth (the Moon, not the Sun)
2. One cycle is about four weeks and other planets also have phases.

Answer 7

At any time, 50% of the moon is illuminated by the sun. But the amount of the illuminated half that we can see from earth changes.

At the time when we can see half of the illuminated half, the moon appears to us like a half-disk.

-- This happens twice during each complete cycle of the moon.

-- At both times, the sun -- earth -- moon form a right angle (90 degrees) with the earth at the vertex.

-- Both times occur one week from New Moon and one week from Full Moon.

Answer 8

-- it rises only a few hours before the sun rises

-- it appears skinnier each night than it appeared the night before

-- the illuminated crescent is the left (eastern) side of the disk, and its points point to the right (west)
(in the northern Hemisphere)

-- it is seen by fewer people than see the waxing crescent ... because relatively fewer people are awake
and outside at that hour of the morning

Answer 9

that there are dark flat creators on the regions of moons surface.

Answer 10

the main surface features are the craters on the moon and the flag apollo13 put on the moon
