固体中を伝わる波は縦波か横波か両方かという問題の解説の補足部分に書いてあったことについて質問です。液体中や気体中で伝わる波で横波は生じないと書いてあるのですが、海の波は横波では無いのですか?

補足 固体中 液体中 気体中のいずれにおいても、 媒質内にずれが生じる場合, ずれを元に戻そうとす る力が,ずれと平行な方向(ただし,ずれと逆向き) にはたらくため(ばね振り子をイメージすると理解 しやすいだろう),媒質の振動方向が波の進行方向 と一致する縦波が生じる。 一方,液体中や気体中では,ずれを元に戻そうと する力はずれに垂直な方向にははたらかない。 こ のため、 液体中や気体中では横波は生じない。 しか し、固体中では,媒質のずれを元に戻そうとする力 が,ずれに垂直な方向にもはたらくため (弦の振動 をイメージすると理解しやすいだろう),媒質の振 動方向が波の進行方向と垂直である横波も生じる。 なお、一般に, 縦波の方が横波よりも速く伝わる。 たとえば, 地震波における初期微動は縦波, 主要動 は横波である。 緊急地震速報は、 縦波の方が速く伝 わることを利用して、 初期微動の観測結果から主要 動の到達予想を知らせる仕組みである。
