70% of the Earth's total surface area is covered by liquid water oceans. The ocean is not only the cradle of human life, but also an important source of water resources, biological resources, and mineral resources on Earth. If we want to protect the ecological environment for human survival, it is our duty to protect the ocean. I believe you must have heard of ocean snot! What exactly is it? Come and learn about it! Contents of this article 1. How is marine snot formed? 2. How deep is the ocean? 3. Where is the source of ocean temperature difference energy? 1How is marine snot formed?It is formed by the accumulation of toxic, gelatinous organic matter produced by tiny marine plankton on the seafloor when they are under pressure. Sea snot is a spherical mucus substance that exists in large quantities in the ocean. It is not only disgusting, but also extremely lethal. The abundance of plankton is due to a warming climate and the uncontrolled growth of plankton caused by nutrient-rich fertilizers and sewage being flushed into the water. Ocean snot is extremely lethal, damaging fishing nets and suffocating marine life. Marine snot contains many dead and rotten bodies of fish and shrimp, as well as a large number of bacteria, which can affect human health to a certain extent. 2How deep is the ocean?The average depth of the world's oceans is 3,688 meters. The Pacific Ocean is the deepest of the five oceans, with an average depth of 3,970 meters. The shallowest of the five oceans is the Arctic Ocean, with an average depth of about 1,205 meters. The ocean area with a depth of more than 200 meters can be called the deep sea. The deep sea is characterized by high pressure, no light, high salinity, low water temperature, slow bottom water flow, rich oxygen content, and more sediments. The deepest point in the world's ocean is the Mariana Trench in the western Pacific Ocean, which has a maximum depth of 11 kilometers. 70% of the Earth's total surface is covered by liquid water oceans. The ocean is not only the cradle of human life, but also an important source of water resources, biological resources, and mineral resources on Earth. 3Where is the source of ocean temperature difference energy?The source of ocean temperature difference energy is solar energy. Ocean temperature difference energy belongs to ocean thermal energy, and its main source of energy is solar radiation energy stored in the ocean. Ocean temperature difference energy has the characteristics of huge reserves and relatively stable changes over time. Using ocean temperature difference energy to generate electricity is expected to provide large-scale and stable electricity for some areas. Seawater temperature difference power generation technology uses the ocean's surface seawater (25℃-28℃) heated by solar energy as a high-temperature heat source and seawater (4℃-7℃) at a depth of 500-1000 meters as a low-temperature heat source to generate electricity using a thermal cycle system composed of a heat engine. The utilization of ocean temperature difference energy is mainly temperature difference power generation. From high temperature heat source to low temperature heat source, effective energy with a total temperature difference of about 15℃-20℃ may be obtained. |
