This science game helps children practice more about moon. You may be interested in knowing the moon's origin, size and shape, and the craters on the surface. But did you know that the moon was created by the same processes as the Earth? The moon is our only natural satellite, and is a quarter of the Earth's diameter. This makes the moon the largest relative to a major planet and larger than any known dwarf planet. This article will help you learn more about the moon.
Origin of the moon
The traditional Giant Impact Model of the Moon's formation assumes that the Moon formed by an impact with a Mars-sized body near the end of its accretion process. The impactor ejected a disk of material into orbit, forming the Moon. Giant impacts are extremely energetic events that vaporize a large part of the body that impacts. Ultimately, the circumterrestrial disk forms a multiphase mixture of vapor and liquid.
While the Moon looks round to us during the night, it is actually an oval shape. Over thousands of years, super-hot tidal forces heated up the Moon's crust, giving it an oblate or lemon-like shape. As a result, the moon's oblate shape has been exaggerated by the gravitational forces of Earth. Scientists initially thought that dust in the Moon's crust would cause lunar landers to sink.
The surface area of the moon is almost the same as the surface area of Russia, the United States, and Canada. Despite these similarities, the moon is so far away from Earth that it would take over 100 years for us to get to it. Similarly, Russia is larger than the moon east to west, but smaller in width north to south. For this reason, the moon has a slightly smaller diameter than the Earth, so our distance to the moon is not so far away, despite being close.
The moon and its craters were formed by the impact of a smaller body upon the moon. The resulting depression formed by the impact is known as an impact crater. The crater was a great depression that was formed because of the tremendous force of the impact. The moon's craters are the result of many years of intense impacts. This makes the moon look like a huge moon, but what is the actual cause of the impact?
What is gravity? Gravity is the force that attracts things with mass, so the more mass an object has, the greater its gravitational pull. A good example of the force is gravity on Mars, the fourth planet from the sun. It is half the diameter of Earth and has seasons, but Mars' mass is still small enough to create microgravity. Microgravity is less than 1/10th the force that holds Earth and Mars together at sea level.
