Never remove a trap with chemicals present; you risk burns to your skin. Call a professional but make certain you inform them of what chemical you used.
Originally Answered: Why is the Moon drifting away by 1 cm each year? Because of tidal forces between moon and Earth. As Earth and moon pull each other, bulges are created on the surface.
When the Moonâs spin slowed enough to match its orbital rate, the bulge was in line with Earth, which is why we always see the same side of the Moon. In our solar system, almost all moons spin at the same rate as they orbit. The Earth would be a very different place if the moon did not exist. Not only did the Earth slow down the Moonâs rotation, but the Moon is slowing down the rotation rate of the Earth. Since the moonâs formation, the Earth has been slowing its rotation due to the friction of the tides caused by the moon, and in reaction to this exchange of energy, the moon has been moving farther away from the Earth.
