Which of the following is a result of sea floor spreading? 1-Trenches form at divergent boundaries.

2-Mid-ocean ridges form at convergent boundaries.

3-Trenches form at transform boundaries.

4-Mid-ocean ridges form at divergent plate boundaries.

Seafloor spreading is a geologic process in which tectonic plates—large slabs of Earth's lithosphere—split apart from each other. Seafloor spreading and other tectonic activity processes are the result of mantle convection. ... The less-dense material rises, often forming a mountain or elevated area of the seafloor.

Explanation:

4-mid ocean ridge at divergent plate boundaries.

this could be newton#'s law of cooling. the cooling curve is exponential
