Question 4. Is the one I need answered on this one **Transcription:****3.** The velocity of sound in water is approximately 1,500 m/s. Calculate the depth from sea level to the ocean floor given the following two-way travel time measurements taken by an echo sounder (see equation above, D=vt/2).- 0.17 seconds:- 3.60 seconds:- 11.23 seconds:**4.** (This exercise is from *Physical Geology* by Steven Earle and is used under a CC BY 4.0 license.) The following map shows part of the sea floor near the southern tip of South America. North is toward the top of the map. Cooler colors (purples and blues) represent lower elevations, and warmer colors represent higher elevations.*Map Description:*The map is a topographical representation of the sea floor. It uses a color-coded system where cooler colors, such as purples and blues, indicate lower elevations and depths, while warmer colors, like reds and oranges, indicate higher elevations and features.**Identify the locations of the following features on the map:**- Continental shelf- Continental slope- Spreading ridge- Subduction zone with a deep trench- An abyssal plain- Some isolated seamounts

Based on the elevation data information given in the question and also based on google earth image of same area given in map, Ocean related features are identified and marked on the map figure. The red portion on the map is continental shelf. Yellow portion is continental slope. Spreading ridge marked on the map. Subduction zone with deep trench marked on the map. Blue portion on the map is abyssal plain. Isolated Seamounts bulging from seafloor are marked on the map.
