Ocean ice is found in Polar Regions. It covers an area of 25 million square kilometers. Ocean ice forms on the surface of the ocean. It grows and melts above oceans. During winter, ocean ice grows but melts during summer (Thompson & William 1). The occurrence of ocean ice has a direct influence on the global climate. Ocean ice has a bright surface that reflects most of the light that strikes it. The co sequence of this phenomenon is that areas that the ocean ice covers have low absorption of solar energy (Ilker 149). In this regard, the temperatures in the solar regions remain cool compared to temperatures of regions covered by lakes. Warm temperatures across the world melt ocean ice. When this happens, the size of bight surfaces available reduces. This increases the amount of solar radiation absorption. The increase in solar radiations leads an increase in temperature at the surface. Thus, a cycle of warming and melting is constituted. The cycle is hindered during winter but commences during spring.
On the other hand, lake ice occurs on fresh water. It freezes as a smooth layer that forms and shapes due to the frequent turbulence of ocean water (Riley et al., 2). Fresh water becomes less dense as it approaches freezing point. This phenomenon is the reason why ice cubes float on the surface of water and why ice layer forms on the surface of lakes and rivers (Nguyen et al., 73). The ocean water increases the density of water when it approaches the freezing point. Because of this, Cold Ocean waters sinks, making ocean ice to form at a slower pace than lake ice. As the water sinks, it cools enough to freeze. In this regard, ice formation on ocean becomes slow process compared to ice formation above the lake. Salt water has a low freezing point compared to fresh water. This is because of the deep levels of ocean water. For ice to form, this water must be cooled to the freezing temperature.
