List at least 3 types of human impacts on the oceans and explain what effects they have on the oceans. SOL Review Worksheet B. Seamount F. Continental Shelf G. Trench 97% Natural part of ocean convection which brings cooler, nutrient rich water from the depths up to the surface Spring tides occur during new and full moons, when the Sun, Earth, and Moon are aligned and gravity is strongest on the water, making the tidal range bigger. Neap tides occur during quarter moons when the Sun, Earth, and Moon make a 90 degree angle. Neap tides have the smallest tidal range. Currents along west coasts are cold water currents whereas currents along east coasts are warm water (such as the Gulf Stream). These currents moderate temperatures so that coastal areas experience less seasonal variation in temperature than inland areas. See #63 above as these problems apply to oceans as well. In addition, global climate change is causing the oceans to warm up and for sea levels to rise. The oceans have become more acidic as more CO2 is released by human activities, which is harmful to fragile organisms with shells such as coral. 11 of 15 Earth Science 2013-2014 70.
