Answer: a.Planting trees in forests that have been harmed 

<span>Almost half of the world's oxygen was supplied by phytoplanktons thru the process of photosynthesis. </span>

<span>The other half is produced on land by trees, and other plants via sunlight (photosynthesis) also.  To stop the world’s oxygen supply from decreasing, we must plant trees that have been harmed. </span>

Natasha_Volkova [10]

Answer:

As the white light moves through the two faces of the prism, the different colors bend different amounts and in doing so spread out into a rainbow. In a rainbow, raindrops in the air act as tiny prisms. Light enters the raindrop, reflects off of the side of the drop and exits.

How is hydro electricity produced step by step explanation ​
timama [110]

Answer:

ydropower, electricity produced from generators driven by turbines that convert the potential energy of falling or fast-flowing water into mechanical energy

Explanation:

In the generation of hydroelectric power, water is collected or stored at a higher elevation and led downward through large pipes or tunnels (penstocks) to a lower elevation; the difference in these two elevations is known as the head. At the end of its passage down the pipes, the falling water causes turbines to rotate. The turbines in turn drive generators, which convert the turbines’ mechanical energy into electricity. Transformers are then used to convert the alternating voltage suitable for the generators to a higher voltage suitable for long-distance transmission. The structure that houses the turbines and generators, and into which the pipes or penstocks feed, is called the powerhouse.
