the claim

Whether a coast has sandy beaches, rocky shores, or cliffs depends mainly on rock resistance, sediment supply, and wave energy.

Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Is it true that whether a coast has sandy beaches, rocky shores, or cliffs depends mainly on rock resistance, sediment supply, and wave energy?

Unclear. Several sources partially support the claim: sediment supply and wave energy are reported to control beach erosion and cliff retreat, and rock strength is cited as reducing coastal retreat. None of the retrieved items covers all three factors together or directly compares sandy, rocky and cliffed coasts.
