28. What causes the northern lights? Earth’s magnetic field The northern lights, aurora borealis, are caused by charged particles emitted by the Sun hitting the Earth's atmosphere. The Earth's magnetic field deflects these charged particles to the north and south poles.

29. The weathering of rocks due to ice is called...? Freeze-thaw weathering Water expands slightly when it freezes into ice. If water gets into a crack in a rock and then freezes, it expands and makes the crack even larger. When the ice melts, more water enters the crack. The water freezes again and makes the crack even bigger. This freezing and thawing process continues until the crack becomes so big that a piece of rock falls off.
