How can satellites orbiting earth determine features on the seafloor without being able to directly observe them beneath several kilometers of seawater?.

BOUNCING MICROWAVES OFFThe satellite measures the variation in the sea-surface altitudes by bouncing microwaves off of the water's surface, which resembles the shape of the seafloor.Measuring the two-way travel time of a sound wave delivered toward the seafloor and back determines the depth of the seafloor.In other words, the satellite can inform scientists on Earth about the height of the oceans and how it fluctuates over time.Historically, Geosat was a top-secret military spacecraft. Today, scientists employ Geosat to indirectly examine the seafloor. The height of the ocean's surface is affected by underwater structures such as mountains and ravines.Learn more about measuring the seafloor here:https://brainly.com/question/14318755#SPJ4
