12/1/2023 0 Comments Sea stack defHow is the ocean basin mapped with sound?Įcho sounders- transmit a sound wave in to the water in order to produce an echo when it bounces off any object Consequently, good vertical mixing between surface and deep waters can occur in high-latitude regions. The water column is iothermal and iopycnal which means that ther is no rapid change in temp. Why does the three-layered structure not exist in high latitudes (close to the pole)? water temp a few degrees above freezing separates the warm surface layer from the deep zone of cold water below Mixing of these waters by waves as well as turbulence from currents and tides created a rapid vertical heat transfer, and this area is nearly uniform in temps. causes water to expand and decrease seawater densityĪ layer of water in which there is a rapid change in temperature in the vertical dimensionĪ layer of water in which there is a rapid change of density with depth.ĭescribe the layered nature of the ocean. How is the density of seawater related to the temperature of seawater? are colder temp, is similar to that are the surface a few degrees above freezing with depth. High temps at surface, but temp decreases rapidly with depth because the Sun's rays can not penetrate vary far into the Ocean.ĭescribe how seawater temperature changes with latitude and depth. The amount of evaporation and precipitation both effect salinity.ĭry subtropics- more evaporation occurs removing water increases salinity.Įquatorial regions or wet ares- more water added and decreases salinity.ĭescribe how seawater temperature changes with latitude and depth. chemical weathering of rocks on the continents (delivered by streams at estimated rate of more than 2.5 billion tons anually)ĭescribe salinity changes with latitude and with depth? What are the main sources for the dissolved materials that are measured by salinity? The total amount of solid material dissolved in water What is salinity and the average salinity of the oceans? Only a little more than 1/4 as deep as the rest of the oceans slightly smaller than Atlantic Ocean but has dame average depth. bounded by almost parallel continental margins largest ocean/ geographic feature on planet It draws on the methods and knowledge of biology, chemistry, physics, and geology to study all aspects of the world ocean. Why is oceanography called a composite science? Is a composite science that studies oceans and oceanic phenomena
