Heave refers to a strong upward or outward movement, often involving lifting or pulling something heavy. This action can be seen in various contexts, such as when a person lifts a large object or when waves crash against the shore. Heaving can also describe the motion of a ship rising and falling on the water. In a more technical sense, heave can relate to geological processes, where soil or rock shifts due to factors like temperature changes or moisture levels. This can lead to ground movement, affecting structures and landscapes. Understanding heave is important in fields like civil engineering and geology.
