By the end of the super glaciations <u>phosphate </u>levels in earth's oceans reached the highest in earth's history, providing nutrients for marine life.
Glaciation, as used in geology, is the process through which glaciers cover the ground. These times are known as glaciations. An ice age's glacial period, or glaciation, is a lengthy (thousands of years) stretch of time characterised by cooler temperatures and glacier advances.
During the end of the period, Antarctica was covered in a vast ice sheet that covered the whole continent and stretched into the ocean onto the middle and outer continental shelves as it is now,.
Living organisms contains large amounts of the mineral phosphate. When the glacier melted oceans and other water body were formed supporting marine life. It also enriched the water bodies with high nutrients like phosphate.

A soda in a styrofoam cup with a lid, coffee in a thermos with the lid closed is the isolated systems.
<h3><u>Explanation:
</u></h3>
Styrofoam cups and thermos containers are typical examples of containers that don’t allow the transfer of heat energy in their environments. A system is said to be isolated if it doesn’t allow heat exchange with its surroundings. A Styrofoam cup with a lid keeps the coffee hot due to its insulation properties.
Thermos container is a more effective insulator since it is made of double-walled container to lock either heat or cold inside. Insulators create effective isolated system depending on the materials they were made from. A completely isolated system does exist.
