The leading theory of the Moon's origin is that a Mars-sized body collided with Earth about 4.5 billion years ago. The resulting debris from both Earth and the impactor accumulated to form our natural satellite 239,000 miles (384,000 kilometers) away. The newly formed Moon was in a molten state, but within … Zobacz więcej With a radius of about 1,080 miles (1,740 kilometers), the Moon is less than a third of the width of Earth. If Earth were the size of a nickel, the … Zobacz więcej The Moon is rotating at the same rate that it revolves around Earth (called synchronous rotation), so the same hemisphere … Zobacz więcej With too sparse an atmosphere to impede impacts, a steady rain of asteroids, meteoroids, and comets strikes the surface of the Moon, leaving numerous craters behind. Tycho Crater is more than 52 miles (85 … Zobacz więcej Earth's Moon has a core, mantle, and crust. The Moon’s core is proportionally smaller than other terrestrial bodies' cores. The solid, iron-rich inner core is 149 miles (240 kilometers) in radius. It is surrounded by a liquid iron … Zobacz więcej WitrynaB) On the Moon, each ʺdayʺ lasts about 15 Earth days of constant sunlight. C) Like our Moon, Mercury does not rotate at all, keeping the same side facing the Sun. D) On Mercury, three days exactly equal two years. E) Our Moon is in a 1:1 synch with the Earth, keeping the same side toward us.

WitrynaMars has a shallow atmosphere compared to Earth, but it is also only 1/3 the size of Earth. Venus and Earth are about the same size and both have atmospheres. A dense atmosphere insulates the surface of a planet so that more heat is retained; however, the composition of the atmosphere is also important. Witryna6 kwi 2024 · Seen only in isolated patches previously, the latest data suggests this layer of ancient ocean floor may cover the core-mantle boundary. Subducted underground long ago as the Earth’s plates shifted, this ultra-low velocity zone, or ULVZ, is denser than the rest of the deep mantle, slowing seismic waves reverberating beneath the surface. Witryna1) the moon is less dense than earth by a quite a lot, astronomers think that the moon must contain More silicate rocks and less metals than Earth. Option 2 is the correct … chris toppen
