Answer 1

The seafloor on a continental shelf is composed of a mixture of oceanic and continental crust.

Step-by-step explanation:

The seafloor on a continental shelf is composed of a mixture of oceanic and continental crust.

The continental shelf is the submerged portion of continent crust in relatively shallow water, extending from the shoreline to the shelf break.

The continental crust is made up of many different types of igneous, metamorphic, and sedimentary rocks, while the oceanic crust is primarily composed of volcanic rocks called basalt.

Answer 2

The seafloor on a continental shelf is primarily composed of continental crust.

The continental shelf is the extended portion of a continent that is covered by relatively shallow seas and is an extension of the continent's landmass. It consists of continental crust, which is less dense and thicker compared to oceanic crust.

Oceanic crust is typically found in deeper ocean basins, and the transition from continental crust to oceanic crust occurs at the continental slope beyond the continental shelf. So, the seafloor on the continental shelf is predominantly composed of the same material as the adjacent continent, which is continental crust.
