Why Is The Sea Salty?

Oceans make up more than 70% of the Earth's surface, making the planet predominantly water-based. However, most of this water is not fresh, meaning it contains high levels of salt and minerals, which can be dangerous to drink. There is so much salt in the oceans, it could cover Earth's surface entirely in a thick layer of salt. But how did this salt get there? Were the seas always salty? Why are the oceans salty, but lakes are not?
