Answer 1

Answer:

• As illumination enters the water, the water consumes white light and reflects just blue light, lights of all colors.
• The earth from space, thus, looks blue.

3. Earth the only planet to have life as

• It is the right distance from the Sun,
• it is protected from harmful solar radiation by its magnetic field,
• it is kept warm by an insulating atmosphere,
• and it has the right chemical ingredients for life, including water and carbon.

Answer 2

Answer:

1) it's not really possible because it's really close to the sun (it means mercury will be very). so no, we can't live on mercury yet but dont know about the future.

2) because 3/4 of the earth is covered from water. That is why most of the earth appears blue. we also call it the blue planet.

3) because we have an atmosphere on earth to live. we have gravity, trees, soil, food and other basic things we need to survive
