Beware of the Ice Age By: Carly zarra

There are 5 main properties of water, Its attraction to polar molecules, high specific heat, high heat of vaporization, the lower density of ice, and high polarity.The color of the snow would appear brighter on a winter day than a sunny day due to the reflection of the colors. Surface and deep water motion is caused by wind, density, temperature, gravity and salinity variations. Ocean current circulations move warm water toward the poles and colder water toward the equator. The wind and the combination of the Earth’s gravitational pull generates the gyres that circle the major oceans basins. And the density of the water. The change in temp and salinity affects waters density.

Plankton play an important role in aquatic environments. They’re important because of their part of the global carbon cycle, they’re the basis of the food web, and they’re the producer of oxygen. Over 90% of marine primary producers production. Diatoms are a common type of phytoplankton and are the primary producers in the food chain. The rising temp in the ocean is what will effect plankton population and it will kill off the fish and other species. It’ll basically throw off the whole entire food chain and it will cause a shortage of fish for humans too. Scientists are warning that the north Atlantic might cool down maybe even as soon as the turn of the century. Rising temperatures could slow down the supply of the tropical water flowing north, it could disrupt the entire ocean circulation pattern.

The temperature has a greater effect on the density of water than salinity does. Increasing salinity also increases the density of seawater. The less dense water will float on top of the more dense water which will give two layers of water with the same salinity. The warmer water will float on top of the colder water. A big enough rise of global temperatures would eventually melt the world's glaciers. Which would release enough water and rise the sea levels a bit. The ocean has had, a significant influence on climate change by absorbing, storing, and moving heat, carbon and water. Changes in the ocean’s circulation have produced large changes in climate during the last 50,000 years. Changes in the ocean-atmosphere system can result in changes to the climate that in turn, cause further changes to the ocean and atmosphere.

If we were to wipe out plankton and algae then we wouldn’t have a food web due to the fact that they’re the basis of the food web. So then all of the fish wouldn’t have anything to eat, and the animals that eat fish would be lacking in the fish category and could possibly starve.
