🏖️ 海滩 = 海 sea + 滩 beach/sandbank — the sandy strip where the sea meets land
海 hǎi is sea (the water radical 氵 on the left). 滩 tān also carries 氵 and means a shallow shore or sandbank, so the pair literally reads sea-shore.
海 — water radical 氵 + 每 (phonetic)
海 is a phono-semantic compound. The 氵 (water) radical signals the meaning—a vast body of water—while 每 supplies the sound. Originally referring to the sea or ocean, it later extended figuratively to mean 'vast' or 'a great quantity,' as in 人海 (a sea of people).
