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.
Viewed from Earth, the Moon appears to rock slowly backwards and forwards so that we see a slightly different face throughout the lunar month. There are two main reasons for this. First, the Moonâs orbit around Earth is elliptical not circular so its rotation is sometimes ahead, and sometimes behind, its orbital motion. And second, the Moonâs rotation axis is not at right angles to its orbit around the Earth so we can sometimes see âoverâ or âunderâ its poles. Over time this means we actually get to see about 59 per cent of the Moonâs surface.
