WebThe giant star was the Sun. Scientists aren’t sure where the oceans’ water came from. Some think it came from water vapor given off by the hot, melted rock. Others think the water flowed out of the rocks as they cooled. Later, the rocks and land released salt into the water. Then, very, very slowly, tiny creatures began to form in the water. WebThe evolution of the oceans has been shaped by a variety of geological processes, including plate tectonics, volcanic activity, and meteor impacts. Plate tectonics, for example, has caused the formation and movement of oceanic plates, which has led to changes in ocean currents, sea level, and climate over millions of years.

Comparing the three conditions, pyruvate formation rate was lowest in water, increased in the presence of the ocean components and achieved its highest rate in the ferrous iron‐rich Archean ocean simulation (Fig 5 C). WebExplain that the earth's crust, or outer covering, is divided into a number of pieces called plates. In total, there are about 15 of these plates. Earth's plates can be terrestrial or oceanic plates. These plates move very slowly and are in constant motion. They move the way ice slabs float and move on water.
