Answer:
The results of the heat wave are the rising of sea levels, the oceans became more acidic, and species disappeared
Step-by-step explanation:
About 56 million years ago, heat wave occurs due to the increase in the concentration of greenhouse gases which are present in the atmosphere. We know that greenhouse gases such as carbon-dioxide etc were the main cause of global warming. Due to this warming, many temperature sensitive species die, melting of ice occurs which increases the sea level and carbon-dioxide deposition occurs in the ocean water which make the water more acidic and the life of marine animals will be adversely affected.
