why is heating water changing its volume
Answer:
As heat increases water begins to evaporate. Evaporation begins at 0C and is at full effect at 100C. So by increasing heat you are increasing rate of evaporation and thus more and more water molecules are lost to the gas phase reducing volume of the water.

What are ocean waves?Ocean waves are the result of the interaction between the ocean and the wind. They are the most visible and powerful manifestations of the Earth's oceans. Ocean waves vary in size, shape, and speed, depending on the wind's strength, duration, and direction. They can range from small ripples to massive swells and can travel thousands of miles before breaking on shorelines.
The energy of ocean waves is harnessed for various purposes, such as surfing, fishing, and generating electricity through wave energy converters. However, ocean waves can also be destructive, causing erosion and flooding in coastal areas during storms.
Ocean waves play a crucial role in regulating the Earth's climate by transferring heat and energy from the tropics to the poles. They also help distribute nutrients and oxygen to marine life, and their movement influences the ocean's circulation patterns.

How did green algae come about
Answer:
Green algae grow at the edges of a glacial lake in Wales. Hundreds of millions of years ago, similar algae adapted to survive temporarily outside of the water may have kicked off the evolution of green land plants.
Algae didn't always hang out in the seas, but one fateful day, about a billion years ago, a simple bacterial cell swallowed a cyanobacteria cell, writes Ed Yong at The Atlantic. This chance occurrence allowed the bacteria to produce energy from the sun, a process known as photosynthesis.
