The elevatiori we call sea level is actually the average level of the sea This means that at average sea kevel, the elevation is zero In reality, the level of the sea rises and fals in what are called tides. Low tide is the point of lowest sea level in a tidal period, High tide is the point of highest sea level ina tidal period. The height above ar below average sca level is caled elevation. An elevation below soa level is consiiered a negative value, whie an elevation above sea level is positive Winston lives near the acean. He rejgularly brings an altimeter to the beadh to measure the elevation of the ocean's surface, You will use the data Winston gathered to cormplete tasks about the rising and falling of the ocean's surface. When necessary, sketch a diagram of the stuation on a separare sheet of paper to assist you. On Monday at 1 p. m., when the ocean's surface was at an elevation of 22 feet, Winston went to surf shop that was 82 leet above the ocar's surface AL7p. m. when the ocean's surface was at an elevation of 24 feet, Winston ate dinrier at a restaurant whose deck was 10 feet above the oceans surface. Part A The ocean went down 4.6ft from 1pm to 7pm.

Part B QUESTION: How many feet apart are the two ocean elevations described in part A?​
